Abstract

A catheter (100) for retrieving a cardiovascular device from within a blood vessel, the catheter (100) comprising: a retrieval module (115) configured to magnetically engage a cardiovascular device within the blood vessel (10) so as to disengage the cardiovascular device from the blood vessel for retrieval from within the blood vessel (10) using the catheter (100).

Claims (25)

1. A catheter for retrieving a cardiovascular device from within a blood vessel, the catheter comprising: a retrieval module configured to magnetically engage a cardiovascular device within the blood vessel so as to disengage the cardiovascular device from the blood vessel for retrieval from within the blood vessel using the catheter.
2. A catheter according to claim 1, wherein the retrieval module comprises a ferromagnetic material.
3. A catheter according to claim 1 or 2, wherein the retrieval module comprises an electromagnet operable to generate a magnetic force.
4. A catheter according to claim 3, wherein the electromagnet is remotely operable.
5. A catheter according to claim 3 or claim 4, wherein the electromagnet is configured to generate a variable magnetic force.
6. A catheter according to any of claims 3 to 5, wherein the retrieval module is connectable to an external power source.
7. A catheter according to any preceding claim further comprising one or more gripping elements arranged to secure the retrieved cardiovascular device to the catheter .
8. A catheter according to any preceding claim further comprising a sheath slidably connected to the catheter and arranged to receive the retrieved cardiovascular device.
9. A catheter according to claim 8, wherein the sheath is arranged to compress the retrieved cardiovascular device in a radial direction upon receipt of the retrieved cardiovascular device.
10. A catheter according to claim 8 or 9, wherein the sheath comprises a tapered profile.
11. A catheter according to any of claims 8 to 10, wherein the sheath is located at a proximal position along the catheter relative to the retrieval module.
12. A catheter according to any preceding claim comprising displacement means for moving at least part of the retrieval module in a radially outward direction.
13. A catheter according to any preceding claim, wherein the cardiovascular device is a replacement heart valve component.
14. A catheter according to claim 13, wherein the magnetic coupling is configured to disengage the replacement heart valve component from a holding member arranged to hold the replacement heart valve component within the blood vessel.
15. A catheter according to any preceding claim further comprising a deployment module arranged to deploy a second cardiovascular device within the blood vessel.
16. A catheter according to claim 15, wherein the deployment module is located at a distal position along the catheter relative to the retrieval module.
17. A catheter according to claim 15 or 16, wherein the deployment module comprises an electromagnet operable to generate a magnetic force .
18. A catheter according to claim 17, wherein the electromagnet is operable to urge a magnetic portion of the second cardiovascular device in a radial direction away from the deployment module.
19. A catheter according to claim 17 or 18, wherein the electromagnet is operable to hold a self-expanding frame to the deployment module.
20. A catheter according to any of claims 15 or 16, wherein the deployment module comprises an inflatable bladder arranged such that inflation of the bladder urges the second cardiovascular device in a radial direction away from the deployment module .
21. A catheter according to any of claims 15 to 20 comprising the second cardiovascular device, wherein the second cardiovascular device is secured to the deployment module.
22. A catheter according to any of claims 15 to 21 when dependent on claim 14, wherein the deployment module is configured to deploy the second cardiovascular device into engagement with the holding member so as to secure the second cardiovascular device within the blood vessel.
23. A catheter according to claim 22, wherein the second cardiovascular device is a second replacement heart valve component.
24. A catheter according to claim 23, wherein the second replacement heart valve component comprises a second magnetic portion for engaging with a corresponding magnetic portion of the holding member .
25. A kit of parts comprising a catheter according to any preceding claim and a cardiovascular device for use with a catheter.
