Flexible biopsy collection device and related methods of use

摘要

Embodiments of the invention are directed to a medical device and methods for collecting a tissue sample from a patient's body. The device may include a first tube defining a lumen and an aperture at a distal end of the first tube. A second tube extends within the lumen of the first tube and defines a lumen and slots, where at least some of the slots have sharp edges configured to shear tissue. The second tube is movable relative to the first tube such that the sharp edges cut a plurality of samples from tissue disposed within the aperture.

主权项

1. A medical device, comprising:
a first tube defining a lumen and an aperture at a distal end of the first tube, the aperture facing a first side of the first tube, the first tube further defining a plurality of discrete slots proximal the aperture and facing a second side of the first tube opposite the first side, wherein each of the discrete slots includes a passageway extending completely through the second side of the first tube, wherein a distal tip of the first tube covers an entirety of a distalmost portion of the lumen of the first tube; and a second tube extending within the lumen of the first tube, the second tube defining a lumen and slots, at least some of the slots of the second tube having sharp edges configured to shear tissue, wherein adjacent slots of the second tube are longitudinally spaced from each other along a longitudinal axis of the second tube; wherein the second tube is configured for lateral deflection, and wherein the second tube is movable relative to the first tube such that the sharp edges cut a plurality of samples from tissue disposed within the aperture.
