Methods and devices for collection of soft tissue
First Claim
1. A tissue sampling apparatus, comprising:
- a body having a primary lumen for receiving a tissue sample, and having a distal end, a proximal end, and a longitudinal axis extending from said proximal end to said distal end;
a cutter having a distal cutting edge and being movable both distally and proximally relative to said body; and
a band having an opening disposed therein and extending across a distal end of said tissue sampling apparatus, said opening being movable relative to said distal cutting edge in order to sever a distal end of said tissue sample.

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.

18. A method of capturing a body tissue sample using a tissue sampling apparatus comprising a body having a lumen extending therethrough and a distal end, a cutting element disposed at the distal end of the body, an opening disposed at the distal end of the body for transverse movement across said distal end, and an actuator for moving the opening, the method comprising:
-
advancing the body through a tissue portion a desire distance so that the cutting element cuts a tissue sample core as the tissue sample enters the lumen; and
actuating the opening to move across the distal end of the body to sever a distal end of the tissue sample core.
