Implant
First Claim
1. An implant for implantation around a circumferential tissue structure in a heart, the implant comprising:
- a flexible elongated component which has a longitudinal axis and which has a first distal end portion, a second distal end portion and an intermediate portion extending between the first and second distal end portions, and one inner lumen extending longitudinally between the first and second distal end portions and through the intermediate portion; and
a locking means configured to allow the first distal end portion to be fixedly connected to the second distal end portion so as to provide the elongated component as a closed loop;
wherein the first distal end portion is provided with a first distal opening which connects the one inner lumen with an outside of the component;
wherein the second distal end portion is provided with a second distal opening which connects the inner lumen with the outside of the component;
wherein the intermediate portion is provided with a proximal opening which connects the one inner lumen with the outside of the component, wherein the proximal opening is longitudinally spaced from both the first and second distal openings; and
wherein the first distal end portion is configured to engage into the second distal opening, the locking means comprises a protrusion which radially protrudes from an outside of the first distal end portion, and when the first distal end portion is in engagement in the second distal opening, the protrusion radially engages with an inner portion of the second distal end portion so as to fixedly secure the engagement of the first distal end portion in the second distal opening.

Abstract
An implant for implantation around a circumferential tissue structure in a heart, includes a flexible elongated component having a longitudinal axis and a first distal end portion, a second distal end portion and an intermediate portion extending between the first and second distal end portions, and an inner lumen extending longitudinally between the first and second distal end portions and through the intermediate portion; and a locking member for allowing the first distal end portion to be fixedly connected to the second distal end portion so as to provide the elongated component as a closed loop. The first distal end portion is provided with a first distal opening which connects the inner lumen with an outside of the component. The second distal end portion is provided with a second distal opening which connects the inner lumen with the outside of the component.

11. A system for implanting an implant around a circumferential tissue structure in a heart of a patient, the system comprising:
-
a flexible elongate continuous guide wire for surrounding the tissue structure, which has a first leg portion with a first free end portion, a second leg portion with a second free end portion, and a loop portion extending between and connecting the first and second leg portions, wherein the loop portion is for distally extending around the tissue structure and the first and second leg portions are for proximally extending from the tissue structure towards an outside of the patient so that the first and second free end portions are accessible for a surgeon, and an implant including; a flexible elongated component which has a longitudinal axis and which has a first distal end portion, a second distal end portion and an intermediate portion extending between the first and second distal end portions, and one inner lumen extending longitudinally between the first and second distal end portions and through the intermediate portion; and a locking means configured to allow the first distal end portion to be fixedly connected to the second distal end portion so as to provide the elongated component as a closed loop; wherein the first distal end portion is provided with a first distal opening which connects the one inner lumen with an outside of the component; wherein the second distal end portion is provided with a second distal opening which connects the inner lumen with the outside of the component; and wherein the intermediate portion is provided with a proximal opening which connects the one inner lumen with the outside of the component, wherein the proximal opening is longitudinally spaced from both the first and second distal openings; wherein the guide wire is disposable or is disposed in the one inner lumen of the component in a manner so that the loop portion extends between the first and second distal end portions, the first leg portion extends from the loop portion through the first distal opening and through the proximal opening so that the first free portion is proximally exposed from the component, and the second leg portion extends from the loop portion through the second distal opening and through the proximal opening so that the second free end portion is proximally exposed from the component, and wherein the implant is moveable along the guide wire in a distal direction, with the first and second distal end portions being simultaneously moveable in a distally leading manner on the first and second leg portions onto the loop portion. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
