Abstract
An implantable prosthetic spacer device can include an inflatable spacer having a plurality of inflatable members and a frame, the frame comprising one or more anchors and one or more clasps. The inflatable spacer can be configured to be disposed between native leaflets of a heart. The implantable prosthetic spacer can be disposed in a symmetrical or an asymmetrical configuration. The inflatable spacers can be inflatable between an uninflated and an inflated configuration.
Claims23
An implantable prosthetic device, comprising:
- an inflatable spacer having an interior cavity, the inflatable spacer being inflatable between an uninflated configuration and an inflated configuration, wherein in the inflated configuration the inflatable spacer is configured to be positioned between native heart valve leaflets to reduce regurgitation therebetween;
- and
- a frame comprising at least one anchor configured to be placed on one side of one of the native leaflets, and a clasp coupled to the anchor and configured to be placed on the other side of the one native leaflet, wherein the clasp is moveable between an open position and a closed position,
- wherein when in the closed position the clasp is configured to retain a portion of the one native leaflet to the anchor, and
- wherein the inflatable spacer is configured to be inflated from the uninflated configuration to the inflated configuration by filling the interior cavity of the inflatable spacer with an inflation medium.
An implantable prosthetic device, comprising:
- an inflatable spacer configured to be positioned between native heart valve leaflets to reduce regurgitation therebetween, the spacer comprising a plurality of inflatable members each having an interior cavity, each inflatable member being inflatable between an uninflated configuration and an inflated configuration;
- and
- at least one anchor configured to anchor the inflatable spacer relative to the native leaflet;
- wherein each inflatable member can be independently inflated to a respective inflated configuration.
A method for improving coaptation of native heart valve leaflets, the method comprising:
- advancing a delivery apparatus and an implantable prosthetic device into a body of a patient, the implantable prosthetic device comprising an inflatable spacer comprising at least first and second inflatable members;
- positioning the inflatable spacer between the native heart valve leaflets;
- and
- at least partially inflating at least the first inflatable member with an inflation medium so that the spacer assumes an asymmetric configuration against which the native leaflets can coapt.
