Abstract
A tissue puncture closure device includes an anchor, a sealing plug, a suture coupled to the sealing plug, a compaction arrangement, and an automatic driving assembly. The automatic driving assembly includes first and second spool members and an actuation member. The first spool member is configured to coil a portion of the suture. The second spool member is configured to coil a portion of the compaction arrangement. The actuation member is coupled to the first and second spool members. Activation of the actuation member releases the first spool member for rotation to apply a tension force in the suture, and releases the second spool member for rotation to distally advance a portion of the compaction arrangement to compress the sealing plug.
Claims20
A tissue puncture closure device, comprising:
- an anchor;
- a sealing plug;
- a suture coupled to the sealing plug;
- a compaction arrangement;
- an automatic driving assembly, comprising:
- a first spool member configured to coil a portion of the suture;
- a second spool member configured to coil a portion of the compaction arrangement;
- an actuation member coupled to the first and second spool members, wherein activation of the actuation member releases the first spool member for rotation thereby applying a tension force in the suture, and wherein activation of the actuation member releases the second spool member for rotation to advance a portion of the compaction arrangement to compress the sealing plug.
A tissue puncture closure device adapted for partial insertion into and sealing of a tissue puncture in an internal tissue wall accessible through a percutaneous incision, the device comprising:
- an anchor disposed on a distal side of the internal tissue wall;
- a sealing plug disposed on a proximal side of the internal tissue wall;
- a suture coupled at a distal end portion to the anchor and the sealing plug, wherein the sealing plug is slidably disposed on the suture proximal of the anchor;
- a compaction arrangement including a compaction member disposed on the suture and configured to drive the sealing plug along the suture distally towards the anchor;
- a first spool member onto which a proximal end portion of the suture is wound;
- a second spool member onto which a portion of the compaction arrangement is wound;
- an actuation member disengageably coupled to the first and second spool members, wherein activation of the actuation member releases the first spool member to rotate thereby providing a tension force in the suture, and wherein activation of the actuation member releases the second spool member to rotate thereby advancing the compaction member distally to compact the sealing plug.
A method of sealing a tissue puncture in an internal tissue wall accessible through a percutaneous incision, the method comprising:
- providing a tissue puncture closure device having an anchor, a sealing plug, a suture coupled to the anchor and sealing plug, a compaction arrangement, first and second spool members, and an actuation member, a portion of the suture being wound about the first spool member, and at least a portion of the compaction arrangement being wound about the second spool member;
- inserting the tissue puncture closure device into the percutaneous incision;
- deploying the anchor through the tissue puncture;
- at least partially withdrawing the tissue puncture closure device from the percutaneous incision;
- actuating the actuation member to release the first and second spool members to permit rotation of the first spool member to create tension in the suture and permit rotation of the second spool member to compact the sealing plug toward the anchor with the compaction arrangement.
