Devices, systems, and methods for supporting tissue and/or structures within a hollow body organ
Devices, systems and methods support tissue in a body organ for the purpose of restoring or maintaining native function of the organ. The devices, systems, and methods do not require invasive, open surgical approaches to be implemented, but, instead, lend themselves to catheter-based, intra-vascular and/or percutaneous techniques.
1. A method to reduce the volume or modify the shape of the heart, the method comprising:
providing at least one implant, wherein the implant comprises a helical fastener;
introducing a guide component from a remote access site into the interior of the heart, wherein the guide component has a deflectable distal tip;
advancing an applier instrument through the guide component, wherein the guide component and/or the applier instrument is configured to possess sufficient column strength to resolve at least a portion of an implantation force, and wherein the implantation force comprises a force necessary to cause the helical fastener to penetrate heart tissue;
bracing a distal portion of the guide component against an interior wall of the heart to apply a resolution force to counteract the implantation force; and
rotating the helical fastener into the heart tissue with the applier instrument to anchor the implant to the heart tissue.
2. The method according to claim 1 , wherein the implant is configured to engage the applier instrument and the applier instrument is configured to apply the implantation force to cause the helical fastener to penetrate the heart tissue.
3. The method according to claim 2 , wherein the implant comprises a tether element.
4. The method according to claim 3 , further comprising anchoring at least two implants, wherein each of the at least two implants comprises a tether element.
5. The method according to claim 4 , further comprising:
providing a clip;
coupling the tether elements together with the clip; and
applying a tensioning force to the tethering elements, wherein the clip maintains tension of the tethering elements.
6. The method according to claim 1 , wherein the guide component is manipulated to provide at least one deflected curve in the distal tip.
7. The method according to claim 1 ,
wherein the interior wall is a first interior wall of the heart,
wherein the heart tissue forms a portion of a second interior wall of the heart, and
wherein the first interior wall is substantially opposite the second interior wall.
