Abstract

A uterine fibroid tissue removal device includes an inner tube disposed within an outer tube and configured to be translated and rotated relative to the outer tube, and a unitary distal tip member attached to a distal end of the inner tube such that the distal tip member translates and rotates relative to the outer tube along with the inner tube, wherein a distal facing open cutting end of the distal tip member in fluid communication with an axial lumen of the distal tip member translates across a tissue resection window in a sidewall of the outer tube so as to sever tissue extending therethrough, the distal tip member axial lumen being in fluid communication with an axial lumen of the inner tube, wherein the axial lumen of the distal tip member is smaller in cross-sectional area than the axial lumen of the inner tube, and wherein the distal tip member has a length greater than a length of the resection window.
