Abstract
A medical device for resecting tissue. The medical device includes a catheter shaft having a proximal portion and two or more distal branch portions. The distal branch portions are moveable between a closed position, and an open position. One or more lumens extend between the proximal portion and through each distal branch portion. An actuation element extends through the lumen of each distal branch portion. A snare loop is connected to each actuation element.
Claims16
A medical device, comprising:
- an elongate member having a proximal end, a distal end, and a first lumen formed therein, wherein the distal end splits into a first distal branch portion having a second lumen, and a second distal branch portion having a third lumen, and the first distal branch portion and the second distal branch portion are each directly fixedly coupled to the distal end of the elongate member, wherein the first and second distal branch portions are movable between a first position, wherein the first and second distal branch portions are disposed relative to one another at a first angle, and a second position, wherein the first and second distal branch portions are positioned relative to one another at a second angle greater than the first angle;
- a snare loop configured to transition between a collapsed configuration and an expanded configuration, and disposed at least partially within the first distal branch portion and the second distal branch portion when in the collapsed configuration;
- and
- first and second actuation elements extending, respectively, through the second and third lumens.
