Treating valve failure
First Claim
Patent Images
1. A device for treating valve failure in a patient, the device having:
- (a) one or more engaging zones for engaging the device with a valve annulus of the valve being treated;
(b) pre-disposition means for changing the geometry of the device to a predetermined configuration suitable for constricting the valve annulus; and
(c) releasably engageable expansion means including one or more struts configured to expand the periphery of the device to substantially match the internal diameter geometry of the valve annuluswherein the device is compressible within a delivery lumen for percutaneous delivery to the valve, and wherein the one or more struts facilitate expansion of the device when released from the delivery lumen to facilitate engagement of one or more engaging zones of the device with the untreated valve annulus, and wherein upon release of the one or more struts the device assumes the predetermined configuration and constricts the valve annulus facilitating substantial closure of leaflets of the valve.

Abstract
A device (1) for treating valve failure in a patient is provided. The device has one or more engaging zones (3) for engaging the device with the annulus of the valve being treated. The device also has pre-disposition means for changing the geometry of the device to a predetermined configuration which is suitable for constricting the valve annulus. The device is compressible for percutaneous delivery to the valve. When in the predetermined configuration, the engaged device constricts the valve annulus facilitating substantial closure of leaflets of the valve.

13. Apparatus for deploying a valve repair device in a patient, the apparatus including:
-
(a) positioning means to position the repair device relative to the valve; (b) coupling means for releasably coupling the repair device to the positioning means; and (c) releasably engageable expansion means including one or more struts configured to expand the periphery of the repair device to substantially match the internal diameter geometry of the untreated valve annulus; wherein the repair device comprises a pre-disposition means for changing the geometry of the device to a predetermined configuration suitable for constricting the valve annulus, and wherein the positioning means and the coupling means are configured to deliver the repair device to a region of the valve within a percutaneous delivery lumen and wherein after delivery of the valve repair device from the delivery lumen the releasably engageable expansion means facilitates engagement of one or more engaging zones of the repair device with the valve annulus. - View Dependent Claims (14, 18)
