    摘要： A seal is provided for effectively inhibiting the egress of fluids from the working channel of an endoscope when an elongate device having a region with a non-circular cross-sectional shape is disposed therein. The seal has a body portion with a proximal end adapted for insertion of the elongate device, a distal end adapted for connection to the proximal end of the endoscope, and a wall defining a lumen adapted to receive the elongate device and to provide access to the working channel of the endoscope. The seal includes a sealing element for sealing the region of the elongate device with a non-circular cross-sectional shape. The sealing element conforms to the profile of the non-circular region.

    摘要： A device for capturing a tissue sample from within a body comprises a needle slidably comprising a needle lumen extending therethrough to a needle opening in the distal end and a stylet slidably received in the needle lumen for movement between an extended position in which a tissue penetrating distal tip of the stylet extends out of the needle opening to penetrate target tissue and a retracted position in which the distal tip of the stylet is received within the needle opening to substantially seal the needle lumen. The stylet further comprises an anchoring feature located proximally of the tissue penetrating distal tip. The anchoring feature comprises a first gripping member including a first proximal facing abutting surface adjacent to a first tissue receiving gap. Movement of the stylet distally out of the needle lumen brings the first gripping member into engagement with surrounding tissue to anchor the stylet at a desired position within the body.

    摘要： A device for penetrating tissues within a living body, comprises a shaft extending from a proximal end which, in an operative position, remains outside the body to a distal end which, in the operative position, is within a living body, the shaft comprising a channel extending therethrough from the proximal end to an opening at the distal end. The device also comprises a needle extending within the channel and comprising a tissue penetrating tip. A portion of an outer surface of the needle includes a first structure wrapping therearound and configured to mate with a second structure formed on a corresponding portion of an inner wall of the shaft. The first and second structures mate with one another so that, as the needle is urged axially through the channel, the mating causes the needle to rotate about an axis of the channel.
