1. A tissue collection device comprising:
a proximal end and a distal end defining a length of the device;
a shaft located along at least a portion of the length, the shaft defining a lumen;
a tendon member residing in the shaft lumen; and
a tissue storage reservoir having an adjustable cross-section, wherein the tissue storage reservoir is movable between a first configuration and a second configuration, the second configuration having a smaller crossing profile and a reduced cross-section relative to the first configuration,
wherein the proximal end is adapted to couple to a catheter and further comprises an opening configured to communicate with the catheter when the catheter is coupled thereto such that excised tissue from the catheter can enter the tissue storage reservoir, and
wherein the tissue storage reservoir comprises a plurality of gaps having a width from 50 μm to 200 μm.
