Medical device maker Endoscopic Technologies brought in an $11 million tranche of second-round funding from Boston Scientific, Telegraph Hill Partners and Saints Capital. The money will be used to further develop the San Ramon, Calif. company’s line of devices that aid in cardiothoracic surgeries like bypasses and valve repairs, reports VentureWire.

Operating under the name Estech, it raised a previous $5 million tranche in 2003. Psilos Group joined Telegraph in that investment. An undisclosed influx of cash also came from Boston Scientific in early 2004.
