Abstract
A guidewire is coupled to a control module and extends through a lumen of the control module. The control module operates to transition between a first control state wherein the control module allows movement of the guidewire relative to a catheter and a second control state wherein relative axial movement between the catheter and guidewire is prevented.
Claims28
A delivery system, comprising:
- a handle maintaining a control module;
- a catheter coupled to the handle and including a lumen;
- and
- a guidewire coupled to the control module and extending through the lumen, the control module operating to transition between a first control state wherein the control module axially moves the guidewire relative to the catheter and a second control state wherein relative axial movement between the handle and guidewire is prevented.
A stent frame delivery system, comprising:
- a handle including at least one actuator;
- a catheter including a lumen and a delivery sheath capsule compressively retaining a stent frame;
- a guidewire positioned within the handle and the lumen of the catheter;
- and
- a control module coupled with the handle and controlling the guidewire to move the guidewire relative to the handle during a first control state and lock the guidewire relative to the handle during a second control state.
A delivery system, comprising:
- a handle;
- a catheter having a lumen, a first end and a second end, the catheter coupled to the handle at the first end;
- a tip coupled to the catheter at the second end of the catheter;
- a control module coupled with the tip;
- and
- a guidewire coupled to the control module and extending through the lumen and the tip, the control module operating to transition between a first control state wherein the control module allows relative axial movement between the tip and guidewire and a second control state wherein the control module prevents relative axial movement between the tip and the guidewire.
The delivery system of claim 26, wherein only one of the first inflatable region and the second inflatable region is inflated in the second control state.
A stent frame delivery system, comprising:
- a handle including at least one actuator;
- a catheter including a lumen, a delivery sheath capsule compressively retaining a stent frame and a tip positioned distal the delivery sheath capsule;
- a guidewire positioned within the handle and the lumen of the catheter;
- and
- a control module coupled with the tip and controlling the guidewire to allow movement of the guidewire relative to the tip during a first control state and prevent movement of the guidewire relative to the tip during a second control state.
