Abstract

An introducer assembly having a handle, at least one fiber operatively coupling at least one handle with one or more functions of the handle; and having a fiber routing system that allows a predetermined amount of slack to be created during assembly in at least one fiber so as to delay by a desired amount of time actuation of the one or more functions of the handle associated with the at least one fiber during operation of the handle.

Claims

1. A medical device deployment system comprising:

an actuating mechanism operatively coupled to a fiber, the actuating mechanism being configured to tension the fiber; and

a fiber tensioning control system comprising;

a series of pins, the fiber being threaded around the pins to define a first tensioned fiber length and first tensioned fiber pattern, at least one of the series of pins configured to be removed such that the first tensioned fiber length changes to a second tensioned fiber length and second tensioned fiber pattern upon removal of the at least one of the series of pins.

2. The medical device deployment system of claim 1, wherein the first tensioned fiber pattern is substantially non-linear.

3. The medical device deployment system of claim 2, wherein the non-linear pattern is zigzag shaped.

4. The medical device deployment system of claim 1, wherein the second tensioned fiber pattern is substantially linear.

5. A medical device deployment system comprising:

a fiber;

an actuating mechanism operatively coupled to the fiber, the actuating mechanism being configured to tension the fiber; and

a fiber tensioning control system through which the at least one fiber is routed, the fiber tensioning control system providing selective fiber slack in a medical device deployment handle, said fiber tensioning control system having a first state, wherein slack is created in the fiber and tension applied to a first fiber end of the fiber translates to a second opposite fiber end of the fiber;

a second state, wherein a route of the fiber through the fiber tensioning control system is altered such that tension applied to the first fiber end is not translated to the second opposite fiber end; and

a third state, wherein slack is created in the fiber and tension applied to the first fiber end translates to the second opposite fiber end.

6. The medical device deployment system of claim 5 further comprising the fiber being wrapped around at least one pin;

and the transition from the first state to the second state is caused by the removal of the at least one pin.

7. An introducer system for endoluminal delivery of vascular implants, said introducer system comprising:

a constraining mechanism for retaining a vascular implant in delivery configuration and being releasable to allow expansion of the vascular implant toward an expanded configuration;

at least one fiber for actuating one or more functions related to the actuation of the constraining mechanism; and

a handle having a fiber routing system through which the at least one fiber is routed, the fiber routing system configured to create a predetermined amount of slack in the at least one fiber by changing a route of the at least one fiber through the fiber routing system so as to delay by a desired amount of time actuation of the one or more functions of the handle associated with the at least one fiber during operation of the handle such that the slack is created in the at least one fiber so that displacement of the at least one fiber produces approximately zero pull force on an opposite end of the at least one fiber.

8. The introducer system as set forth in claim 7, wherein the fiber routing system includes a series of pins through which the at least one fiber is routed.

9. The introducer system as set forth in claim 8, wherein the at least one fiber is threaded about the series of pins defining a first tensioned fiber length and first tensioned fiber pattern, wherein tension applied to one end of the at least one fiber translates to an opposite end of the at least one fiber.

10. The introducer system as set forth in claim 9, wherein removal of at least one of the series of pins creates the predetermined amount of slack in the at least one fiber.

11. The introducer system as set forth in claim 10, wherein the at least one fiber has a second tensioned fiber length and a second tensioned fiber pattern after the slack is removed by tensioning of the at least one fiber.

12. The introducer system as set forth in claim 11, wherein tensioning the at least one fiber from the first tensioned fiber length and pattern to the second tensioned fiber length and pattern causes the delay in the actuation of the one or more functions of the handle associated with the at least one fiber during operation of the handle.

13. An introducer system for endoluminal delivery of vascular implants, said introducer assembly comprising:

a constraining mechanism for retaining a vascular implant in delivery configuration and being releasable to allow expansion of the vascular implant toward an expanded configuration;

at least one fiber for actuating one or more functions related to the actuation of the constraining mechanism; and

a handle having a fiber routing system, the fiber routing system having a series of pins through which the at least one fiber is routed, defining a first tensioned fiber length and a first tensioned fiber pattern, wherein tension applied to one end of the at least one fiber translates to an opposite end of the at least one fiber, the fiber routing system allowing, during assembly of the handle, a predetermined amount of slack to be created in the at least one fiber so as to delay by a desired amount of time actuation of the one or more functions of the handle associated with the at least one fiber during operation of the handle; and

wherein removal of at least one of the series of pins creates the predetermined amount of slack in the at least one fiber.
