Abstract

Methods and apparatuses are disclosed for closing a patent foramen ovale. Some of the disclosed apparatuses include an elongate body having a proximal end and a distal end, with first and second suture clasp arms adapted to hold end portions of a suture when in an extended position. A first suture catch mechanism is slidably housed in the elongate body and moves in a proximal-to-distal direction to engage the suture end held by the first suture clasp arm, and a second suture catch mechanism is slidably housed in the elongate body and moves in a distal-to-proximal direction to suture end held by the second suture clasp arm. The first suture clasp arm can be positioned around the septum primum to deliver a suture thereto, and the second suture clasp arm can be positioned around the septum secundum to deliver a suture thereto.

Claims (53)

1. A device for applying a knot to a suture, the device comprising:

a handle;

an elongate tubular member having a proximal end and a distal end, wherein the proximal end of the elongate tubular member is coupled to the handle, and wherein the elongate tubular member comprises a first opening at the distal end and a second opening on a side wall of the elongate tubular member near the distal end, wherein the first opening and the second opening are configured to receive a suture such that the suture extends through the second opening and out the first opening;

an actuator rod having a proximal end and a distal end that extends through and is translatable longitudinally within the elongate tubular member, the actuator rod further comprising a tip at the distal end of the actuator rod and a cutting edge that is rotatable about a longitudinal axis of the elongate tubular member; and

a knot body and a plug for positioning within the distal end of the elongate tubular member;

wherein the handle is usable to distally advance the actuator rod to cause the tip to force the plug into the knot body to secure the suture between the knot body and the plug when the knot body and the plug are positioned within the distal end of the elongate tubular member and the suture extends through the second opening and out the first opening; and

wherein the handle is usable to rotate the actuator rod to rotate the cutting edge to cut the suture.

2. The device of claim 1 , wherein when the actuator rod is in a proximal position, the handle is configured to resist rotation and when the actuator rod is in a distal position, the handle is configured to allow rotation of the actuator rod to rotate the cutting edge to cut the suture.

3. The device of claim 1 , wherein the handle comprises a housing, a button and a knob.

4. The device of claim 3 , wherein advancing the button into the housing causes the actuator rod to advance distally.

5. The device of claim 3 , wherein the knob is rotatable to rotate the actuator rod and rotate the cutting edge to cut the suture.

6. The device of claim 1 , further comprising a sleeve in the distal end of the elongate tubular member, the sleeve having a side opening configured to receive the suture, wherein the sleeve is configured to support the knot body and the plug.

7. The device of claim 6 , wherein the side opening in the sleeve has a cutting edge that is configured to cooperate with the cutting edge of the actuator rod to cut the suture.

8. A device for applying a knot to a suture, the device comprising:

a knot body and a plug for positioning within the distal end of the elongate tubular member;

wherein depressing the button is configured to advance the actuator rod to cause the distal end of the actuator rod to force the plug into the knot body to secure the suture between the knot body and the plug when the knot body and the plug are positioned within the distal end of the elongate tubular member and the distal end of the elongate tubular member is coupled to the suture; and

wherein the knob is actuatable to cut the suture with the cutting edge.

9. The device of claim 8 , wherein the cutting edge is rotatable about a longitudinal axis of the elongate tubular member by rotating the knob.

10. The device of claim 8 , further comprising a sleeve inside the elongate tubular member near or at the distal end of the elongate tubular member, the sleeve having a side opening configured to receive the suture, wherein the sleeve is configured to support the knot body and the plug.

11. The device of claim 10 , wherein the side opening in the sleeve has a cutting edge that is configured to cooperate with the cutting edge of the actuator rod to cut the suture.

12. A device for applying a knot to a suture, the device comprising:

a handle comprising a housing, a button and a knob;

an elongate tubular member having a proximal end and a distal end, wherein the proximal end of the elongate tubular member is coupled to the handle, and wherein the elongate tubular member comprises a first opening at the distal end and a second opening on a side wall of the elongate tubular member near the distal end, wherein the first opening and the second opening are configured to receive a suture such that the suture extends through the second opening and out the first opening;

an actuator rod having a proximal end and a distal end that extends through and is translatable longitudinally within the elongate tubular member, the actuator rod comprising a tip at the distal end of the actuator rod and a cutting edge that is rotatable about a longitudinal axis of the elongate tubular member; and
