Abstract
A medical device includes an elongate shaft having a proximal end portion, a distal end portion, and a defining a lumen therebetween. The distal end portion defines al least one slot. An expandable member is disposed, within the lumen, the expandable member being configured to protrude outward from the at least one slot when expanded with cryogenic fluid.
Claims20
A medical device, comprising:
- an elongate shaft having a proximal end portion, a distal end portion, and defining a lumen therebetween;
- the distal end portion defining at least one slot;
- and
- an expandable member disposed within the lumen, the expandable member being configured to protrude outward from the at least one slot when expanded with cryogenic fluid.
