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.
Claims20
A medical device, comprising:
- a catheter, including:
- a proximal portion having a first lumen,
- a first distal branch portion having a second lumen, and
- a second distal branch portion having a third lumen,
- 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;
- first and second actuation elements extending, respectively, through the second and third lumens;
- and
- a snare loop connected at a first location to the first actuation element and connected at a second location to the second actuation element.

A medical device, comprising:
- an elongate member having a proximal end, a distal end, and a lumen formed therein, wherein the distal end splits into two or more branches, each branch having a lumen formed therein;
- and
- an expandable wire loop configured to transition between a collapsed configuration and an expanded configuration, and disposed at least partially within the two or more branches when in the collapsed configuration.
A method for manipulating tissue, comprising:
- inserting a medical device within a body cavity, the medical device comprising:
- a catheter, including:
- a proximal portion having a first lumen,
- a first distal branch portion having a second lumen, and
- a second distal branch portion having a third lumen,
- 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;
- first and second actuation elements extending, respectively, through the second and third lumens;
- and
- a snare loop connected at a first location to the first actuation element and connected at a second location to the second actuation element,
- advancing an introduction sheath to a desired location within the body;
- positioning the snare distally relative to a distal end of the introduction sheath;
- deploying the snare over the tissue to be resected;
- and
- manipulating the tissue with the medical device.
