Luminous Medical raises $24M for automated glucose monitoring – Carlsbad, Calif.-based Luminous Medical, a medical-device maker, raised $23.5 million in a second funding round. Investors included Adams Street Partners, RiverVest Venture Partners, Finistere Ventures, De Novo Ventures and Latterell Venture Partners.

Luminous is developing an automated blood-sugar sensor for diabetic patients being treated in hospital intensive-care units and operating rooms. According to the company, keeping a tight rein on blood-glucose levels, which can soar or crash unexpectedly in diabetics, helps prevent complications while shortening hospital stays and reducing the risk of death.

Measuring such tight control, however, typically requires manually checking blood-glucose levels every 30 to 60 minutes, the company says. The Luminous device, by contrast, uses infrared spectroscopy — a technique that identifies particular molecules by measuring which wavelengths of light they absorb — to measure glucose and other blood chemicals non-invasively.

The company licensed its technology from InLight Solutions of Albuquerque, N.M., which previously invested $60 million in the technology. The device has not been approved by the FDA.

Axial Biotech takes in $6M for spinal diagnostics – Axial Biotech, a Salt Lake City diagnostic-test maker, raised $6 million as part of its second funding round. Investors included Johnson & Johnson Development, vSpring Capital and Ohio Biotech Group.

Axial, founded in 2002 by a group of spinal surgeons and geneticists, is an odd hybrid of biotech and devices. The company aims to produce tests that will predict and measure the severity of spinal problems such as scoliosis, as well as unspecified “motion-preserving technologies” — presumably an alternative to the stigmatizing back braces that orthopedists have long inflicted on children with the condition.

Insulin bioengineer enGene receives $6.4M – Canada’s enGene, a Vancouver biotech looking for ways to jump-start natural insulin production in diabetics, raised $6.4 million in a first round of funding. Investors included Saad Investments, Masa Life Science Ventures and private investors.

EnGene has an audacious — which is to say, of course, also quite chancy — approach to diabetes, in which the immune system attacks and kills insulin-producing “beta cells” in the pancreas (type 1 diabetes) or the body grows desensitized to insulin and requires higher levels (type 2 diabetes). In either case, patients often require insulin shots to maintain blood-sugar levels necessary or proper metabolism.

EnGene proposes to engineer cells in the small intestine — known as “K cells” — to produce insulin themselves. The advantage of this technique lies in the fact that K cells, like beta cells, respond to sugar levels in the gut, although they normally secrete a separate molecule. Once bioengineered to produce insulin as well, these cells could help regulate blood sugar automatically much the way beta cells normally do.

Of course, gene therapy has, in general, been a great disappointment so far, so there’s no shortage of uncertainty associated with this sort of technique. EnGene has tested its technique in mice, but not yet in humans. The startup plans to seek a second round of funding in the second half.

Alimera Sciences gets $30M for eye-disease drug – Alimera Sciences, an Alpharetta, Ga., drug developer with a focus on eye disease, raised $30 million in a third funding round. The company will now take a majority stake in its drug for diabetic macular edema, a vision-degrading complication of diabetes, which Alimera is developing with its partner pSividia.

We’ve written before about Alimera, which is presumably still contemplating an IPO this fall. All five of the company’s existing VC backers participated in the round: BA Venture Partners, Domain Associates, Intersouth Partners, Polaris Venture Partners and Venrock Associates.

Vaccine maker LigoCyte draws $28M – LigoCyte Pharmaceuticals, a Bozeman, Mont., biotech focused on new vaccines against infectious disease, raised $28 million in a third funding round. Investors included Forward Ventures, JAFCO, Novartis Venture Fund, Fidelity Biosciences, MedImmune Ventures, Athenian Venture Partners and MC Life Sciences Ventures.

The company is developing new vaccines using “virus-like particles” — usually structural viral proteins, minus the replication machinery packed in DNA or RNA — against gastroenteritis, anthrax and flu. It is also working on antibody drugs against inflammatory disease.

Featured companies: Reliant Technologies, Leptos Biomedical, Calidora Skin Clinic

Reliant Tech seeks $95M IPO for dermatology lasers — Mountain View, Calif.-based Reliant Technologies, a developer of medical lasers for “skin rejuvenation” treatment, filed to raise as much as $95 million in an initial offering. The company currently markets two laser systems for skin treatment under the Fraxel brand name, and intends to launch a third one next year.

Oddly enough, Reliant Tech’s IPO filing comes just days after Reliant Pharmaceuticals filed for a $400 million initial offering (see our coverage in this daily briefing). That should certainly keep investors on their toes. Journalists, too — I almost didn’t cover this IPO because I thought I’d already written about it.

Although it has products on the market, Reliant Tech is not only still losing money, its losses are apparently continuing to mount. Total revenues have grown substantially, to $57.4 million in 2006 from $4.5 million in 2004, but its net losses have also kept pace, largely as a result of mounting sales and marketing expenses. Net losses in 2006 were $20.9 million, up from $13.3 million in 2004; for the first half of 2007, the company posted a loss of $10.9 million on $35.3 million in revenue.

Reliant Tech raised $37 million in its two most recent fundings, most recently drawing in $15 million in a fifth round, according to VentureWire (subscription required).

Neuromodulator Leptos raises $20M for obesity implant — Leptos Biomedical, a Brooklyn Center, Minn., developer of obesity-control implants, raised $20 million in a third funding round, VentureWire reports. Investors included Latterell Venture Partners, Spray Venture Partners, Thomas McNerney & Partners and Technology Partners.

Leptos is developing what it calls an “implantable pulse generator” designed to send electric signals into the sympathetic nervous system in order to suppress appetite and induce the burning of fat. The company has apparently already conducted a pilot trial of the device, which it says the new funding will allow it to extend. Leptos hasn’t disclosed additional details about its technology; on its Web site, the page devoted to approach is a two-paragraph stub filled with boilerplate.

I’ve written earlier about EnteroMedics, another company hoping to treat obesity using an implant that interferes with signals transmitted along the vagus nerve — you can read our previous coverage here. In general, the whole field of “neuromodulation” is heating up quite a bit these days, with companies hoping to use timed electrical pulses to the nervous system for treating everything from epilepsy to sleep apnea to hypertension — although it’s worth bearing in mind that almost all of these approaches are so far unproven. See our previous coverage of other companies in this space here, here, here, here, and here.

Founded in 2003, Leptos is the brainchild of serial physician-entrepreneur John Dobak, who previously founded hypothermia-inducer InnerCool Therapies and CryoGen, which developed a cryothermic technique for stanching uterine bleeding. Both companies have since been acquired — InnerCool for $6 million (after raising $49 million) and CryoGen for something between $40 million and $150 million (after raising roughly $60 million).

Skin-clinic chain Calidora raises $4M for SoCal expansion — Calidora Skin Clinic, a chain of four “medical-aesthetic” skin-care clinics in the Seattle area, raised $4 million in a first funding round to expand its operations into southern California. Roughly half the funding was provided by the company’s existing angel investors and insiders, with Fluke Venture Partners providing the rest.

From the release:

Courtion said the funding enables the completion of expansion plans underway in Manhattan Beach, Marina Del Ray, and Glendale, Calif., and other real estate and partnership opportunities on the near horizon. The company is working with Southern California based Caruso Affiliated, a leading retail developer, on two of the three properties, including the Americana at Brand, which is slated to open in downtown Glendale in Spring of 2008.

CardioMind, a secretive Sunnyvale, Calif., developer of stents designed to prop open blocked arteries, raised $33 million in a third round of funding, VentureWire reports (subscription required). From the VentureWire story:

CardioMind, with 30 employees, is developing small-diameter drug-eluting stents and delivery devices for cardiovascular and neurological indications and has been largely operating in stealth mode for the past five years.

SV Life Sciences and De Novo Ventures led the round, joined by InterWest Partners, Latterell Venture Partners, Morgenthaler Ventures and Onset Ventures.

CardioMind had previously raised $20 million in two financing rounds, according to VentureWire.

Despite recent concerns over the safety of drug-eluting stents, which are coated with a substance designed to prevent growth of scar tissue that can reblock arteries, new stent companies have continued to get a warm welcome from investors. Menlo Park, Calif.-based Xtent, for instance, raised $76 million in a February IPO. In May, Devax, a Lake Forest, Calif., stent developer, filed to raise up to $85 million in an IPO.

Talima Therapeutics, a Santa Clara, Calif., developer of techniques that limit drug delivery to specific parts of the body, raised $19 million in a second funding round. The company’s release is here.

The company is at work on localized drug-delivery techniques that could serve as alternatives to systemic drugs, potentially improving their effectiveness while limiting side effects. Its initial focus lies in dermatology, a field in which “local application” — that is, ointments, creams and lotions — is already in common practice. Talima hasn’t revealed much about its technology beyond describing it as a “micro-implant” system, which could mean almost anything. The new funding will carry its leading drug candidates — whatever they are — into mid-stage human testing.

The round was led by US Venture Partners and Latterell Venture Partners, joined by current investors De Novo Ventures and Palo Alto Healthcare.

Palo Alto, Calif.-based Pulmonx raised $20 million in a second-round funding, VentureWire reports (subscription required).

The startup is one of several device makers hoping to pioneer new medical techniques in the field of “interventional pulmonology.” Much like interventional cardiology, in which non-surgeons perform procedures such as angioplasty and stenting to open blocked arteries, interventional pulmonology aims to give lung specialists new tools to treat lung problems such as emphysema in their offices. Patients, of course, could benefit from quicker recovery times and avoiding hospitals as well, at least if the procedures are proven to be equal or superior to existing techniques.

According to VentureWire:

Richard M. Ferrari, managing director of De Novo, said that these companies, like Pulmonx, are looking to replace the current mode of treatment: lung volume reduction surgery. “It’s an incredibly invasive procedure,” he said. “So the concept of having an office-based procedure is irresistible.”

Pulmonx’s technology involves the insertion of a one-way valve, shutting off diseased portions of the lung. Ferrari said that the technique is part of a growing field of interventional pulmonology, which, like the more established field of interventional cardiology, uses catheter-based treatments for diseases.

Pulmonx has been in trials outside of the U.S., Ferrari said, and plans to begin human implantations in the U.S. later this year or early next year. “The $20 million will take them well into their clinical trials,” he said.

The round was led by De Novo Ventures. Others involved in the round include new investor Latterell Venture Partners and existing investors Montreux Equity Partners and MedVenture Associates.
