  • Patent number: 9980812
    Abstract: 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.

  • Publication number: 20040133221
    Abstract: A connector assembly for joining a graft vessel to a target vessel. The assembly includes a tubular connector member provided with tines at a distal end thereof, the tines extending inwardly of the connector member and then radially outwardly and then proximally at sharp ends thereof, the tines being adapted to engage end portions of the graft vessel and thereafter wall portions of the target vessel, a spreader portion comprising a tubular body slidably disposed in the tubular connector member and movable to engage the inwardly extending tines and force the tines into position substantially disposed in a hypothetical extension of walls of the connector member, and a seal portion slidably disposed around the connector member and provided with flanges for engagement with the target vessel in wall areas proximate the tines to clamp target vessel wall portions to the tines.
