Abstract
A deflection mechanism for use in an elongate medical device is presented. The deflection mechanism comprises an actuator. The actuator comprises a rotatable body comprising a channel. The deflection mechanism further comprises an activation wire having a proximal end and a distal end, and a wire lock attached to the proximal end of the activation wire. The wire lock is disposed within the channel and is configured to ride therein when the actuator body is rotated. An elongate medical device, and a handle assembly thereof, that incorporate the deflection mechanism are also presented.
Claims22
A deflection mechanism for use in an elongate medical device, comprising:
- an actuator comprising a rotatable body, said body comprising a channel;
- an activation wire having a proximal end and a distal end;
- and
- a wire lock attached to said proximal end of said activation wire;
- wherein said wire lock is disposed within said channel and is configured to slide within said channel so as to move relative to said channel, when said actuator body is rotated.
A handle assembly for use in a steerable elongate medical device, comprising:
- a housing defining a cavity;
- and
- a deflection mechanism, said deflection mechanism comprising
- an actuator comprising a rotatable body at least a portion of which is disposed within said cavity of said housing, said body comprising a channel,
- an activation wire having a proximal end and a distal end, and
- a wire lock attached to said proximal end of said activation wire, wherein
- said wire lock is disposed within said channel and is configured to slide Within said channel so as to move relative to said channel when said actuator body is rotated, and further wherein
- said activation wire extends from said channel and into said cavity of said housing.
An elongate medical device, comprising:
- an elongate shaft comprising a proximal end portion and a distal end portion;
- a pull assembly disposed within said shaft at said distal end portion thereof;
- a handle disposed at said proximal end portion of said shaft, said handle comprising a housing defining a cavity;
- and
- a deflection mechanism configured to deflect said elongate shaft, said deflection mechanism comprising
- an actuator comprising a rotatable body that at least a portion of which is disposed within said cavity of said housing of said handle, said body comprising a channel;
- an activation wire having a proximal end and a distal end, said distal end of said activation wire being coupled to said pull assembly and said activation wire extending from said pull assembly to said actuator body;
- and
- a wire lock attached to said proximal end of said activation wire;
- wherein
- said wire lock is disposed within said channel and is configured to slide within said channel so as to move relative to said channel when said actuator body is rotated, and
- said activation wire extends from said channel and into said cavity of said housing of said handle.
