Abstract
Abstract A tissue sampling apparatus comprises a tubular body having a primary lumen for receiving a tissue sample. The tubular body includes a distal end, a proximal end, and a longitudinal axis extending from the proximal end to the distal end. The tissue sampling apparatus further comprises a cutting cylinder having a distal cutting edge, which is movable both distally and proximally relative to the tubular body. A band having an eyelet disposed therein extends across a distal end of the tissue sampling apparatus, wherein the eyelet is advantageously movable relative to the distal cutting edge in order to sever a distal end of the tissue sample.

Claim 20
Independent Claim
118 words
A method of capturing a body tissue sample using a tissue sampling apparatus comprising a tubular body having a lumen extending therethrough and a distal end, a cutting element disposed at the distal end of the tubular body, an eyelet disposed at the distal end of the tubular body for transverse movement across said distal end, and an actuator for moving the eyelet, the method comprising: advancing the tubular body through a tissue portion a desired distance so that the cutting element cuts a tissue sample core as the tissue sample enters the lumen; and actuating the eyelet to move across the distal end of the tubular body to sever a distal end of the tissue sample core.
Claim 21
Independent Claim
118 words
A method of capturing a body tissue sample using a tissue sampling apparatus comprising a tubular body having a lumen extending therethrough and a distal end, a cutting element disposed at the distal end of the tubular body, an eyelet disposed at the distal end of the tubular body for transverse movement across said distal end, and an actuator for moving the eyelet, the method comprising: advancing the tubular body through a tissue portion a desired distance so that the cutting element cuts a tissue sample core as the tissue sample enters the lumen; and actuating the eyelet to move across the distal end of the tubular body to sever a distal end of the tissue sample core.
