초록 ▼

A heart valve implant is disclosed herein. The heart valve implant comprises an inflatable valve body, a shaft, an anchor assembly and an inflation (injection) port. Also disclosed herein, are methods of trans-apically and trans-septally delivering a heart valve implant within a heart such that the valve body can be inflated in situ to partially or completely restrict blood flow through a heart valve in a closed position. The inflation (injection) port permits inflation of the valve body with an adjustable amount of an inflation fluid to attain a desired degree of inflation of the valve body when disposed within the heart valve.

대표청구항 ▼

1. A heart valve implant comprising: an inflatable valve body defining a cavity comprising a proximal end and a distal end;a shaft extending through the proximal end of the inflatable valve body, said shaft comprising a lumen in fluid communication with said cavity;an anchor assembly attached to the shaft, proximal to the inflatable valve body; andan inflation port comprising one or more lumens in fluid communication with the shaft lumen, wherein said inflation port is configured to be secured subdermally;wherein: the anchor assembly comprises a passageway and two arms;the passageway is positioned between said two arms and is configured to receive and advance the shaft;each of the two arms defines an opening; andthe anchor assembly is configured to be secured to an exterior surface of an individual's heart. 2. The heart valve implant of claim 1, further comprising one or more radiopaque markers. 3. The heart valve implant of claim 2, wherein the one or more radiopaque markers are at or near the proximal end of the inflatable valve body. 4. The heart valve implant of claim 1, wherein the inflation port further comprises a pierceable septum configured to fluidly seal the inflation port. 5. The heart valve implant of claim 4, wherein the pierceable septum comprises silicone. 6. The heart valve implant of claim 5, wherein the inflation port further comprises one or more suture holes. 7. The heart valve implant of claim 4, wherein the pierceable septum is liquid-tight. 8. The heart valve implant of claim 1, wherein one or more sutures are placed around each of the two arms of the anchor assembly. 9. The heart valve implant of claim 1, wherein the inflatable valve body is partially or completely inflated with an inflation fluid. 10. The heart valve implant of claim 1, wherein the shaft is attached to the distal end of the inflatable valve body. 11. The heart valve implant of claim 10, wherein the lumen in fluid communication with the inflatable valve body comprises one or more openings.
