Abstract

A fixed sequence activation handle is described that forces a predetermined activation sequence. Such handles are suitable for use in the delivery of medical devices or for other application that require a fixed sequence of activations.

First claim

What is claimed is:

1. A cable retention system in a device handle for use in the delivery of medical devices, the system comprising:
a. at least one retaining element;
b. a substrate having a cavity dimensioned to allow an insertion of the at least one retaining element, the cavity including a maximum dimension smaller than a maximum dimension of the retaining element;
c. a first slot extending from a first edge of the substrate to said cavity; and
d. a second slot extending from a second edge of the substrate to said cavity wherein the first and second slots are dimensioned to allow a placement of a cable within the slots, the at least one retaining element including a curved surface and being configured to retain the cable in the cavity due to a friction fit between the substrate and the at least one retaining element.

2. The system of claim 1 , wherein the cavity includes a curved bottom section, and the first and second slots include edges that extend into the curved bottom section.

3. The system of claim 2 , wherein the curved surface of the at least one retaining element is configured to deform the cable into a shape of the curved bottom section to retain the cable in the cavity.

4. The system of claim 3 , wherein the at least one retaining element includes a spherical shape and is configured to deform the cable into a shape of the curved bottom section to retain the cable in the cavity.

5. The system of claim 1 , wherein an interference fit between the cavity and the at least one retaining element retains the cable in the cavity.

6. The system of claim 1 , wherein the cavity includes at least one alignment guide configured to align the retaining element within the cavity.

7. The system of claim 1 , wherein the first and second slots extend to said cavity on opposing sides thereof.

8. A method of retaining a cable in a device handle for use for use in the delivery of medical devices, the method comprising the steps of:
a. providing the device handle having a substrate with a cavity, a first slot and a second slot;
b. positioning the cable within the first and second slot to cross the cavity; and
c. positioning at least one retaining element including a curved surface within the cavity to secure the cable between the retaining element and the substrate due to a friction fit between the substrate and the at least one retaining element, the cavity including a maximum dimension smaller than a maximum dimension of the retaining element.

9. The method of claim 8 , wherein the cavity includes a curved bottom section and positioning the at least one retaining element includes deforming the cable into a shape of the curved bottom section to retain the cable in the cavity.

10. The method of claim 8 , wherein positioning at least one retaining element includes forcing the at least one retaining element into the cavity to create an interference fit between the cavity and the at least one retaining element to retain the cable in the cavity.

11. The method of claim 8 , wherein the at least one retaining element includes a spherical shape, positioning the at least one retaining element includes deforming the cable into a shape of the curved bottom section to retain the cable in the cavity.

12. The method of claim 8 , providing the device handle includes providing the first slot and the second slot extending to the cavity on opposing sides thereof.
