Abstract: A method includes depositing a plurality of layers over a substrate. The layers include read sensor layers and an electrically conductive layer substantially coplanar with the read sensor layers and substantially surrounding the read sensor layers. The electrically conductive layer is in contact with at least one of the read sensor layers. The electrically conductive layer provides an electrical path between the at least one of the read sensor layers and ground. The method further includes forming an isolation structure around the read sensor layers by removing a portion of the electrically conductive layer substantially surrounding the read sensor layers. The isolation structure is substantially coplanar with the read sensor layers and substantially surrounds the read sensor layers. The isolation structure breaks the electrical path between the at least one of the read sensor layers and the ground.

Abstract: A device for cleaning a lens of an endoscope inside a patient during a surgical procedure may include a cannula having a proximal end, a distal end and an opening, and an expandable member coupled with the cannula such that when fluid is introduced into the expandable member, it expands out of the opening in the cannula. A method for cleaning a lens of an endoscope inside a patient during a surgical procedure may involve: advancing a cannula into the patient; passing fluid into an expandable member coupled with the cannula to expand the expandable member, wherein some of the fluid passes through the expandable member to an outer surface of the expandable member; and contacting the endoscope lens with the outer surface of the expandable member, located inside the patient, to clean the lens.

Abstract: A device for cutting tissue in a human body may include an elongate, hollow shaft having a proximal portion and a distal portion, a bundle of flexible wires slidably disposed within at least a portion of the shaft and having a proximal end and a distal end, and an actuator coupled with the proximal portion of the shaft and the proximal end of the bundle of wires. The distal end of the bundle may be configured to facilitate cutting of tissue, and the wires of the bundle may be at least partially free to move, relative to one another, to allow a cross-sectional shape of the bundle to differ along a length from the proximal to the distal end. The actuator may be configured to move the wires back and forth through the hollow shaft to cause the distal ends of the wires to cut tissue.
