Abstract
Polypectomy devices and methods for making and using polypectomy devices are disclosed. An example polypectomy device may include an elongate sheath extending from a proximal end region to a distal end, the elongate shaft including an inner reinforcing layer and an outer insulating layer, a shaft slidably disposed within the sheath, a handle coupled to the proximal end of the sheath, a longitudinal actuator disposed about the handle and secured to a proximal end of the shaft, and a snare coupled to a distal end of the shaft.
Claims20
A polypectomy device, comprising:
- an elongate sheath extending from a proximal end to a distal end, the elongate shaft including an inner reinforcing layer and an outer layer;
- a shaft slidably disposed within the sheath;
- a handle coupled to the proximal end of the sheath;
- a longitudinal actuator disposed about the handle and secured to a proximal end of the shaft;
- and
- a snare coupled to a distal end of the shaft.
A polypectomy device, comprising:
- an elongate sheath extending from a proximal end to a distal end, the elongate sheath comprising:
- an inner reinforcing layer;
- an outer insulating layer disposed over a radially outward surface of the inner reinforcing layer;
- and
- a tubular distal tip extending distally from a distal end of the inner reinforcing layer and free from the outer insulating layer;
- a shaft slidably disposed within the sheath;
- a handle coupled to the proximal end of the sheath;
- a longitudinal actuator disposed about the handle and secured to a proximal end of the shaft, the longitudinal actuator movable relative to the handle;
- an electrical connector configured to electrically couple the shaft with an external power source;
- and
- a snare coupled to a distal end of the shaft.
A polypectomy device, comprising:
- an elongate sheath extending from a proximal end to a distal end, the elongate sheath comprising:
- an inner reinforcing layer comprising a stainless steel helically wound filar;
- an outer insulating layer disposed over a radially outward surface of the inner reinforcing layer;
- and
- a tubular distal tip extending distally from a distal end of the inner reinforcing layer and free from the outer insulating layer;
- a shaft slidably disposed within the sheath;
- a handle coupled to the proximal end of the sheath;
- a longitudinal actuator disposed about the handle and secured to a proximal end of the shaft, the longitudinal actuator movable relative to the handle;
- and
- a snare coupled to a distal end of the shaft.
