Abstract
Methods and systems for minimally invasive replacement of a valve. The system includes a collapsible valve and anchoring structure, devices and methods for expanding the valve anchoring structure, adhesive means to seal the valve to the surrounding tissue, a catheter-based valve sizing and delivery system, native valve removal means, and a temporary valve and filter assembly to facilitate removal of debris material. The valve assembly comprises a valve and anchoring structure for the valve, dimensioned to fit substantially within the valve sinus.
Claims41
A valve assembly to be endovascularly implanted within a body channel, comprising:
- an anchoring structure wherein the anchoring structure is collapsible and expandable to fill the body channel;
- a collapsible valve connected to the anchoring structure, wherein the collapsible valve is configured to permit fluid to flow in a first direction and prevent fluid to flow in a second direction;
- an multiple outer circumferential concentric reservoirs attached at an outermost radius of the anchoring structure when the anchoring structure is at an expanded state;
- and
- a sealable fixation compound housed within the reservoirs.
A method of endovascularly implanting a collapsible valve assembly within a body channel, comprising the steps of:
- providing a collapsible valve connected to an anchoring structure, the collapsible valve and anchoring structure being expandable to fill the body channel, the collapsible valve being further configured to permit fluid to flow in a first direction and prevent fluid to flow in a second direction, the anchoring structure having attached outer circumferential multiple concentric reservoirs located at an outermost radius of the anchoring structure when the anchoring structure is at an expanded state, wherein the reservoirs contains a sealable fixation compound for securely fixing the valve assembly at a desired body channel location;
- passing the collapsible valve assembly to the desired body channel location;
- excreting the sealable fixation compound from the reservoirs when the anchoring structure is at an expanded state;
- and
- sealing the anchoring structure onto a tissue at the desired body channel location by activating the sealable fixation compound.
