    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.

    摘要： A sheath for a medical instrument includes an elongate body extending from a proximal end to a distal face. The elongate body may be configured to axially extend from a first length to a second length greater than the first length. The sheath may include a first hollow lumen extending from a first end proximate the proximal end to a second end proximate the distal face, and a second hollow lumen extending from the proximal end to the distal face. The second lumen may be open at the distal face. The sheath may also include a transparent window positioned at the second end of the first lumen to seal the first lumen at the second end. The transparent window may be configured to transmit light therethrough.
