1. A fixed sequence activation handle comprising:
- a first removable member attached to a first distally extending line for communication with a remotely located deployable device;
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; and
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,wherein the third distally extending line maintains communication between the second distally extending line and the deployable device,wherein rotation of said rotatable portion modulates a first portion of the deployable device without causing axial displacement of the rotatable portion relative to the second member.

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 rotatable portion modulates the first portion of the deployable device without causing axial displacement of the second removable member, wherein removal of said second member results in complete deployment of the first portion of the device and allows access to the third member, and 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:
-
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; delivering the deployable device to a target location; removing the first member from the handle to partially deploy the first portion of the device and allow access to the second member; rotating a rotatable portion of the second member to modulate the first portion of the deployable device without causing axial displacement of the second removable member; removing the second member to complete deployment of the first portion of the device and allow access to the third member; and manipulating the third member to deploy the second portion of the device resulting in delivery of the deployed device.

10. A fixed sequence activation handle comprising:
-
a first removable member attached to a first distally extending line for communication with a remotely located deployable device; and 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 and a third distally extending line each for communicating with the remotely located deployable device, the third distally extending line maintaining communication between the second distally extending line and the deployable device, wherein rotation of said rotatable portion modulates a first portion of the deployable device via axial displacement of the second distally extending line without causing axial displacement of the third distally extending line. - View Dependent Claims (11)
