Abstract
A delivery system comprises a catheter configured to be delivered through a blood flow pathway of a heart and an implant configured to maintain an opening in a tissue wall to allow blood flow through the opening and into the blood flow pathway and be delivered via the catheter. The implant is at least partially composed of a flexible material to allow the implant to bend with the catheter.
Claims34
A delivery system comprising:
- a catheter configured to be delivered through a blood flow pathway of a heart;
- and
- an implant configured to:
- maintain an opening in a tissue wall to allow blood flow through the opening and into the blood flow pathway;
- and
- be delivered via the catheter, the implant being at least partially composed of a flexible material to allow the implant to bend with the catheter;
- wherein the implant comprises a puncture element configured to puncture through a tissue wall to create the opening in the tissue wall.
4 more elements
A method comprising:
- delivering an implant enclosed at least partially by a sheath to a coronary sinus via a right atrium, wherein the implant is at least partially composed of braided or coiled cords to allow the implant to bend into the coronary sinus;
- puncturing a tissue wall of the coronary sinus with the implant to create an opening between a left atrium and the coronary sinus;
- retracting the sheath to expose the implant;
- and
- anchoring the implant at the opening, wherein the implant is configured to maintain the opening.
2 more elements
A medical implant comprising:
- means for maintaining an opening through a tissue wall of a heart, the opening creating a blood flow path from a first chamber of a heart to a blood flow pathway of the heart, the means for maintaining the opening comprising a means for puncturing the tissue wall to create the opening, and the means for maintaining the opening configured to bend to facilitate delivery into the blood flow pathway and the first chamber;
- and
- means for anchoring to the tissue wall at the opening.
