Abstract

A method is provided for the transcatheter delivery of an intracorporeal device and includes establishing a device delivery pathway in a patient. The device delivery pathway extends at least from an entry point into the patient to an exit point from the patient. A method is also provided for the transcatheter retrieval of an intracorporeally implanted device and includes establishing a device delivery pathway in a patient, wherein the device delivery pathway extends at least from an entry point into the patient to an exit point from the patient. A delivery device is also provided for the transcatheter delivery of an intracorporeal device through a device delivery pathway in a patient, the delivery device comprising a catheter comprising a radial separation mechanism, or a delivery catheter and detachably coupling with an intracorporeal device.

Claims

1. A method for the transcatheter delivery of an intracorporeal device comprising:

a step of establishing a device delivery pathway in a patient, wherein said device delivery pathway extends at least from an entry point into the patient to an exit point from the patient, and

a step of coupling the intracorporeal device to a delivery system, said delivery system being arranged and configured to extend, in use, at least to the entry point and to the exit point of the device delivery pathway,

wherein the delivery system comprises at least two delivery devices, each delivery device being coupled to an end of the intracorporeal device.

2. The method according to claim 1 wherein the entry point and/or the exit point is generated by a radial, subclavian, jugular, carotid, and/or femoral access procedure to allow entry into and/or exit from a radial, subclavian, carotid, jugular and/or femoral vein or artery.

3. The method according to claim 1, wherein the device delivery pathway is partly or wholly in the circulatory system.

4. The method according to claim 1, wherein the delivery site is located in the patient'"'"'s heart.

5. The method according to claim 1, wherein the delivery site is across one or more anatomical walls.

6. The method according to claim 1, comprising a step of positioning a sheath and/or catheter along part or whole of the device delivery pathway.

7. The method according to claim 1, wherein the delivery device comprises an elongate flexible member and means for coupling an end of said member with the intracorporeal device.

8. The method according to claim 7, wherein the elongate flexible member comprises or consists of a delivery catheter.

9. The method according to claim 7, wherein the elongate flexible member comprises or consists of a wire and/or cable.

10. The method according to claim 7, wherein the elongate flexible member comprises a portion for receiving an end of the intracorporeal device.

11. A method for the transcatheter delivery of an intracorporeal device comprising:

a step of establishing a device delivery pathway in a patient, wherein said device delivery pathway extends at least from an entry point into the patient to an exit point from the patient, and

a step of coupling the intracorporeal device to a delivery system, said delivery system being arranged and configured to extend, in use, at least to the entry point and to the exit point of the device delivery pathway, wherein the delivery system comprises one delivery device which extends from the entry point to the exit point of the device delivery pathway.

12. The method according to claim 11, wherein the delivery device comprises a catheter, said catheter comprising a radial separation line.
