Abstract
An embodiment of a medical device includes a proximal handle, a distal end effector, an elongate member connecting the end effector to the handle, and a sheath enclosing at least a portion of the elongate member. The handle may include a first mechanism coupled to one of the sheath and the elongate member to move the sheath relative to the elongate member, a second mechanism coupled to the elongate member to rotate the elongate member relative to the handle, and a locking mechanism coupled to the first mechanism to hold the first mechanism in a default position. Embodiments also include methods of positioning the medical device to perform a medical procedure.

1-38. (canceled)
A medical device, comprising:
- a handle having a proximal end and a distal end;
- a sheath having a lumen extending along a longitudinal axis;
- a shaft having a proximal end received by the handle, and a distal end including an end-effector, wherein at least a portion of the shaft extends through the lumen of the sheath;
- a first actuator coupled to one of the sheath and the shaft, the first actuator including a rotatable member and a linearly translatable member, wherein the rotatable member is movable into and out of engagement with the linearly translatable member, wherein the rotatable member is biased to move out of engagement with the linearly translatable member, and wherein the rotatable member is rotatable about an axis perpendicular to the longitudinal axis;
- and
- a second actuator coupled to the shaft and rotatable about an axis that is one of coaxial with and parallel to the longitudinal axis.
A medical device, comprising:
- a handle having a proximal end and a distal end;
- a sheath having a lumen extending along a longitudinal axis;
- a shaft having a proximal end received by the handle and a distal end including an end-effector, wherein at least a portion of the shaft extends through the lumen of the sheath;
- a first actuator coupled to one of the sheath and the shaft, wherein the first actuator includes a rotatable member and a linearly translatable member, wherein the rotatable member is movable into and out of engagement with the linearly translatable member, wherein the rotatable member is biased to move out of engagement with the linearly translatable member, and wherein the rotatable member is rotatable about an axis extending transverse to the longitudinal axis;
- a second actuator coupled to the shaft and rotatable about an axis that extends in a direction in which the longitudinal axis extends;
- and
- a stiffening member extending along the longitudinal axis and at least partially received by the linear translatable member, wherein the stiffening member circumferentially surrounds the shaft.
A method of positioning a medical device to perform a medical procedure, comprising:
- with a distal end effector of a medical device positioned within a sheath of the medical device, advancing the distal end effector to a treatment site, wherein the distal end effector is operatively coupled to a handle of the medical device via a shaft that extends through the sheath;
- moving a first actuator of the handle from a first state toward a second state by pressing a first rotatable member of the first actuator in a direction transverse to a longitudinal axis of the sheath, wherein in the first state, the first rotatable member engages a portion of a housing of the handle, and wherein in the second state, the first rotatable member disengages from the portion of the housing, and the first rotatable member engages a linearly translatable member coupled to the shaft or the sheath;
- extending the distal end effector distally of the sheath by rotating the first rotatable member to longitudinally advance the linearly translatable member;
- and
- actuating a second actuator of the handle to rotate the end effector about the longitudinal axis of the sheath.
