Abstract
Embodiments of the present disclosure include a medical device including, among other things, an elongated member having a proximal end, a distal end, and at least one channel. A distal portion of the at least one channel may be displaced relative to a longitudinal axis of the elongated.
Claims19
A medical device comprising:
- a tubular member having a proximal end, a distal end, and a channel extending between the proximal and distal ends, wherein a distal portion of the channel is displaced relative to a central longitudinal axis of the tubular member, wherein the distal portion of the channel is defined by a cap secured to the distal end of the tubular member, wherein the distal portion of the channel is housed within a lumen of the cap, wherein a position of the distal portion of the channel does not change relative to the lumen, wherein the lumen has a greater cross-sectional dimension than a cross-sectional dimension of the distal portion of the channel and the lumen surrounds the distal portion of the channel, wherein the channel crosses the central longitudinal axis of the tubular member between a proximal end of the cap and a distal end of the cap, and wherein a distal-most end of the channel opens through a wall of the cap that defines the lumen.
A medical device comprising:
- a tubular member having a proximal end, a distal end, and a channel extending there between;
- and
- a cap coupled to the distal end of the tubular member, wherein the cap defines (a) an interior surface defining a lumen, wherein the lumen extends to a distal-most end of the cap;
- and (b) a diverter tube fixed in a stationary position relative to the lumen and extending within the lumen from a proximal end portion of the cap, wherein the diverter tube is displaced relative to a longitudinal axis of the tubular member, wherein the diverter tube is spaced apart from the interior surface of the cap between a proximal end of the diverter tube and a distal end of the diverter tube, and wherein the distal end of the diverter tube includes a sidewall having a notch.

A method for resecting tissue from a patient, the method comprising:
- inserting a resection device into a body cavity, the resection device comprising:
- a tubular member having a proximal end, a distal end, and at least one channel extending between the proximal and distal ends, wherein a distal portion of the at least one channel is disposed in a cap and displaced relative to a central longitudinal axis of the tubular member, wherein the cap defines an open lumen extending between a proximal end of the cap and a distal end of the cap, wherein the distal portion of the channel extends within the open lumen, a position of the distal portion of the channel does not change, and the lumen surrounds the distal portion of the channel, wherein the distal portion of the channel crosses the central longitudinal axis of the tubular member between the proximal end of the cap and the distal end of the cap, and wherein a distal-most end of the channel opens through a wall of the cap that defines the open lumen;
- and
- advancing an instrument through the tubular member and into the distal portion of the at least one channel to excise tissue.
