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.

Claims

1. A fixed sequence activation handle comprising:

a. a first removable member attached to a first distally extending line for communication with a remotely located deployable device;

b. a second removable member having a rotatable portion, the second member at least partially covered by said first removable member and attached to a second distally extending line for communication with the remotely located deployable device;

c. a third member at least partially covered by said second removable member and attached to a third distally extending line for communication with the remotely located deployable device.

2. The fixed sequence activation handle of claim 1, wherein the presence of the first member prevents the removal of the second member.

3. The fixed sequence activation handle of claim 1, wherein the presence of the second member prevents the removal of the third member.

4. The fixed sequence activation handle of claim 1, wherein the third member is

nested within the second member;

and

the second member is nested within the first member.

5. The fixed sequence activation handle of claim 1, wherein the third member is removable.

6. The fixed sequence activation handle of claim 1, further comprising an access port to at least one of said first, second or third distally extending lines.

7. A fixed sequence activation handle comprising:

a. a first removable member attached to a first distally extending line for communication with a remotely located deployable device; and

b. a second member having an adjustment feature, said second member at least partially covered by said first removable member and attached to a second distally extending line for communication with the remotely located deployable device.

8. A fixed sequence activation handle comprising:

at least a first, second and third removable member each attached to a distally extending line in communication with a remotely located deployable device having a first and second portion;

wherein removal of the first member from the handle results in partial deployment of the first portion of the device and allows access to the second member;

wherein the second member includes a rotatable portion wherein rotation of said portion modulates the first portion of the deployable device

wherein removal of said second member results in complete deployment of the first portion of the device and allows access to the third member;

wherein manipulation of the third member deploys the second portion of the device.

9. A method of delivering a deployable device comprising the steps of:

a. providing a handle having at least a first, second and third removable member each attached to at least one distally extending line for communication with a remotely located deployable device having a first and second portion;

b. delivering the deployable device to a target location;

c. removing the first member from the handle to partially deploy the first portion of the device and allow access to the second member;

d. rotating a rotatable portion of the second member to modulate the first portion of the deployable device;

e. removing the second member to complete deployment of the first portion of the device and allow access to the third member; and

f. manipulating the third member to deploy the second portion of the device resulting in delivery of the deployed device.

10. A cable retention 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,

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 an elongate member within the slots so that the retaining element retains the elongate member in the cavity.

11. A method of retaining an elongate member in a device handle comprising the steps of :

a. providing a device handle having a substrate with a cavity, a first slot and a second slot

b. positioning at least one elongate member within the first and second slot to cross the cavity; and

c. positioning at least one retaining element within the cavity so that the at least one elongate member is secured between the retaining element and the substrate.
