Detachment actuator for use with medical device deployment systems
First Claim
1. An actuator for use with an implantable medical device deployment system including a control member that controls the release of the implantable medical device upon movement of the control member, the actuator comprising:
- a first portion, a second portion and a fracturable member located between the first and second portions, said first portion being adapted to be connected to the deployment system and said second portion being adapted to be connected to the control member; and
said second portion being detachable from said first portion upon the application of torque to either said first portion or said second portion, thereby fracturing the fracturable member and allowing said second portion to be separated by a distance from said first portion to cause movement of the control member through an elongated carrier member to release the medical device.

Abstract
A detachment actuator for use with an implantable medical device deployment system that guide and deploys the medical device at a target location within a body vessel. The detachment actuator includes a first portion that is connected the implantable medical device and a second portion that is attached to a control member the controls the release of the medical device, The second portion of the detachment actuator detaches and moves away from the first portion of the detachment actuator to move the control member and release the medical device.

9. An actuator for use with an implantable medical device deployment system including a control member that controls the release of the implantable medical device upon movement the control member, the actuator comprising:
-
a first portion, a second portion and a fracturable member located between the first and second portions, wherein said first portion and said second portion are integral, said first portion being adapted to be connected to the deployment system and said second portion being adapted to be connected to the control member; and the fracturable member between the first and second portions such that said second portion is detachable from said first portion by fracturing said fracturable member by applying torque to the first portion or the second portion of the actuator, thereby allowing said second portion to be separated by a distance from said first portion to cause movement of the control member through an elongated carrier member to release the medical device, wherein the actuator is configured to be fractured by applying torque to the first portion or the second portion of the actuator. - View Dependent Claims (10, 11)

12. A deployment system for delivering an implantable medical device to a target location of a body vessel, comprising:
-
a generally elongated carrier member having a proximal end portion and a distal end portion; an implantable medical device releasably attached to the distal end portion of the carrier member a control member whose movement through the elongated carrier member causes the release of the implantable medical device from the distal end portion of the carrier member; an actuator including a first portion, a second portion and a fracturable member located between the first and second portions, said first portion of the actuator being connected to the carrier member and said second portion of the actuator being connected to the control member; and said second portion of the actuator being detachable from said first portion of the actuator upon the application of torque to either said first portion or said second portion of the actuator, thereby fracturing the fracturable member and allowing said second portion of the actuator to be separated by a distance from said first portion of the actuator to cause movement of the control member and release of the implantable medical device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method of deploying an implantable medical device to a target location of a body vessel, comprising:
-
providing a generally elongated carrier member having a proximal end portion and a distal end portion, an implantable medical device releasably secured to the distal end portion of the carrier member, a control member whose movement through the elongated carrier member causes the release of the implantable medical device from the distal end portion of the carrier member, an actuator including a first portion, a second portion and a fracturable member located between the first and second portions, said first portion of the actuator being connected to the proximal end portion of the carrier member and said second portion of the actuator being connected to the control member; positioning the implantable medical device generally adjacent to a target location within a body vessel; detaching the second portion of the actuator from the first portion of the actuator by applying torque to either the first portion or second portion of the actuator thereby fracturing the fracturable member; and separating the second portion of the actuator from the first portion of the actuator, thereby causing movement of the control member and release of the medical device. - View Dependent Claims (23, 24, 25)
