Abstract
A medical device that includes a handle, an actuator movably coupled to the handle, a shaft extending distally from the handle, and a sheath including a distal end disposed within the shaft and a proximal end disposed within the handle. The sheath includes a plurality of branches secured to one another at the distal end and separated from one another at the proximal end. The actuator is coupled to each of the plurality of branches at the proximal end of the sheath, and the actuator is configured to move each of the plurality of branches relative to one another to articulate the shaft in a plurality of directions.
Claims20
A medical device, comprising:
- a handle;
- an actuator movably coupled to the handle;
- a shaft extending distally from the handle;
- and
- a sheath including a distal end disposed within the shaft and a proximal end disposed within the handle, wherein the sheath includes a plurality of branches secured to one another at the distal end and separated from one another at the proximal end;
- wherein the actuator is coupled to each of the plurality of branches at the proximal end of the sheath, and the actuator is configured to move each of the plurality of branches relative to one another to articulate the shaft in a plurality of directions.
A medical device, comprising:
- a handle;
- an actuator rotatably coupled to the handle;
- a shaft extending distally from the handle;
- and
- a sheath including a plurality of branches, wherein the plurality of branches are secured to the actuator at a proximal end and to the shaft at a distal end, wherein the plurality of branches are movable relative to one another at the proximal end and immovable relative to one another at the distal end;
- wherein the actuator is configured to articulate the shaft by rotating relative to the handle and translating at least one of the plurality of branches relative to the remaining plurality of branches.
A medical device, comprising:
- a handle;
- a shaft extending distally from the handle;
- an end effector at a distal end of the shaft;
- an actuator secured to the shaft, wherein the actuator is configured to provide omnidirectional movement of the distal end of the shaft;
- and
- a sheath disposed within the shaft and defining a lumen that receives the end effector, wherein a proximal end of the sheath is attached to the actuator and a distal end of the sheath is attached to the shaft;
- wherein the sheath is bifurcated into at least a first branch and a second branch, and the actuator is configured to move the first branch relative to the second branch at the proximal end of the sheath to articulate the distal end of the shaft and deflect the end effector.
