Deployment handle for a medical device deployment system
First Claim
Patent Images
1. A deployment handle for an introducer assembly, the handle comprising:
- a first actuating mechanism for actuating an implantable device deployment arrangement, the first actuating mechanism including a first helical guide, the implantable device deployment arrangement including a constraining sheath that is axially displaceable between a first state releasably constraining an implantable device toward a delivery configuration for endoluminal delivery and a second state allowing deployment of the implantable device;
a second actuating mechanism for actuating a blocking arrangement between a first state in which access to one or more functions of the handle is blocked and a second state in which the access to one or more functions of the handle is unblocked; and
a knob operatively coupled to both of the first and second actuating mechanisms to cause concurrent operation of both of the first and second actuating mechanisms in response to actuation of the knob, the first actuating mechanism being movable with the knob about a rotational axis.

Abstract
An introducer assembly includes a first actuating mechanism for actuating a constraining sheath between a first state releasably constraining a vascular implant and a second state allowing deployment of the vascular implant; a second actuating mechanism for actuating a blocking mechanism between a blocked state for blocking other functions of the handle and an unblocked state for allowing operation of the other functions of the handle; and an operating knob operatively coupled to both of the first and second actuating mechanisms for concurrent operation of both of the first and second actuating mechanisms in response to actuation of the operating knob.

14. A medical device deployment handle comprising:
-
a first actuating mechanism for actuating a first implantable device deployment component; a first knob; a cover; a second actuating mechanism for actuating the cover relative to the second actuating mechanism and causing the deployment handle to transition from a first state in which the first knob is concealed by the cover to a second state in which the cover has been actuated such that the first knob is revealed, the first knob being distinct from the first and second actuating mechanisms and being configured to actuate a second implantable device deployment component; and a second knob operatively coupled to each of the first and second actuating mechanisms to cause concurrent actuation of both of the first and second actuating mechanisms in response to actuation of the second knob, the first and second knobs being independently actuatable such that the first and second knobs can be actuated relative to one another. - View Dependent Claims (15, 16, 17)

18. A deployment handle assembly comprising:
-
a constraining sheath; a displacement member for retracting the constraining sheath from covering an implantable medical device; a first knob for actuating a component of the handle assembly; and a second knob that is actuatable to cause the handle to transition from a first state in which the first knob is inaccessible to a second state in which the first knob is accessible, the second knob being actuatable to cause the displacement member to retract the constraining sheath from covering the implantable medical device, the first and second knobs being independently actuatable such that the first and second knobs can be actuated relative to one another. - View Dependent Claims (19, 20, 21)
