TRI-BENDING SPHINCTERTOME |
摘要 |
Disclosed herein are devices and methods for forming multidirectional cuts in tissue. The tissue cutting devices disclosed herein generally include a flexible elongate member with at least first, second, and third wires that are at least partially constrained within or along a portion of the member. A distal portion of the wires is anchored on or within a portion of the elongate member. When tension is applied to at least one of the wires, such as by an actuator at a proximal end of the device, the elongate member bows while an unconstrained portion of the wire becomes exposed relative to the adjacent portion of the elongate member, assuming a tissue-cutting configuration. |
