Abstract

Medical devices for applying a cinch to one or more suture and cutting the suture, and methods for making and using such devices are disclosed. An example medical device may include an elongated shaft, a connection sleeve, a cinch sleeve coupled to the connection sleeve, and a cinch member. An elongated inner shaft may extend through and be longitudinally movable within the elongated shaft, connection sleeve, cinch sleeve, and cinch member.

First claim

What is claimed is:

1. A medical device for applying a cinch to one or more sutures, the medical device comprising:
an elongated shaft defining a shaft lumen;
a connection sleeve having a sleeve lumen and releasably coupled with the elongated shaft;
a cinch sleeve defining a cinch lumen and having a proximal portion configured to releasably engage the connection sleeve;
a cinch member defining a cinch member lumen, the cinch member including at least a proximal segment configured to fit within the cinch lumen; and
an elongated inner shaft extending through and longitudinally movable within the shaft lumen, the sleeve lumen, the cinch lumen, and the cinch member lumen;
wherein:
an opening is defined radially through the outer surface of the cinch sleeve and into the cinch lumen;
at least one suture cutting element is disposed on one or both of the connection sleeve and the opening; and
proximal movement of the cinch sleeve with respect to the connection sleeve engages one or more sutures extending through the opening with the at least one suture cutting element to cut the one or more sutures with the at least one suture cutting element.

2. The medical device of claim 1 , further comprising a coupler connected to the elongated shaft, the coupler having a coupler lumen and a distal coupling member, wherein the connection sleeve includes a first connector and a second connector, wherein the first connector is configured to releasably engage the distal coupling member to be releasably coupled with the elongated shaft.

3. The medical device of claim 2 , wherein the cinch sleeve has at least one proximal coupling member releasably engaged with at least the second connector of the connection sleeve.

4. The medical device of claim 3 , wherein when the cinch sleeve moves toward a proximal position from a distal position, the at least one proximal coupling member disengages from the second connector of the connection sleeve and moves proximally, releasing the distal coupling member of the coupler from the first connector of the connection sleeve.

5. The medical device of claim 1 , wherein the sleeve lumen has a sleeve lumen diameter, and the cinch sleeve has an outer surface defining a shoulder, the shoulder having a proximally facing shoulder surface and a shoulder diameter greater than the sleeve lumen diameter, wherein the proximal portion of the cinch sleeve extends proximal of the shoulder.

6. The medical device of claim 5 , wherein when the cinch sleeve is in a distal position, a gap is defined between the proximally facing shoulder surface and a distally facing end surface of the connection sleeve.

7. The medical device of claim 1 , wherein a distal end section of the elongated inner shaft is configured to releasably engage the cinch member lumen, wherein proximal movement of the elongated inner shaft moves the cinch member from a first configuration in which at least a part of the cinch member is spaced apart from a distal end of the cinch sleeve, to a second configuration in which the cinch member engages the cinch lumen.

8. The medical device of claim 7 , wherein from the second configuration, further proximal movement of the elongated inner shaft disengages the connection sleeve from the elongated shaft, resulting in a third configuration.

9. The medical device of claim 8 , wherein further proximal movement of the elongated inner shaft moves the coupled cinch member and cinch sleeve from the third configuration to a fourth configuration in which a cinch assembly including the cinch member, cinch sleeve, and connection sleeve is separated from the elongated shaft.

10. The medical device of claim 9 , wherein the cinch member lumen has a distal section and a proximal section, wherein a diameter of the distal section is larger than a diameter of the proximal section, wherein the elongated inner shaft includes a distal region having a diameter larger than the diameter of the proximal section of the cinch member lumen, wherein the distal region is compressible such that application of a predetermined amount of proximal force compresses the distal region, allowing it to move into the proximal section of the cinch member lumen.

11. The medical device of claim 1 , wherein a distal end section of the elongated inner shaft is configured to releasably engage the cinch member lumen, wherein proximal movement of the elongated inner shaft moves the cinch member from a first configuration in which at least a part of the cinch member is spaced apart from a distal end of the cinch sleeve, to a second configuration in which the cinch member engages the cinch lumen.

12. The medical device of claim 11 , wherein further proximal movement of the elongated inner shaft disengages the elongated shaft from the cinch member.

13. The medical device of claim 1 , wherein as the cinch member moves proximally, a proximal end of the cinch member disengages the connection sleeve from the elongated inner shaft.

14. The medical device of claim 1 , further comprising a suture extending longitudinally through the cinch lumen and radially out the opening defined through the outer surface of the cinch sleeve.

15. The medical device of claim 1 , wherein the suture cutting element is disposed on one of a distally facing end surface of the connection sleeve or the opening in the cinch sleeve.

16. A suture cinch comprising:
a connection sleeve having a sleeve lumen;
a cinch sleeve defining a cinch lumen and an opening defined radially through the outer surface of the cinch sleeve into the cinch lumen; and
a cinch member defining a cinch member lumen, the cinch member including at least a proximal segment configured to fit within the cinch lumen; and
at least one suture cutting element disposed on one or both of the connection sleeve and the opening;
wherein proximal movement of the cinch sleeve from a distal position to a proximal position engages the at least one suture cutting element for cutting one or more sutures extending through the opening.

17. The suture cinch of claim 16 , wherein the connection sleeve has first and second connectors, and the cinch sleeve has at least one proximal portion with at least one proximal coupling member configured to releasably engage either of the first and second connectors.

18. The suture cinch of claim 17 , wherein the at least one proximal coupling member is engageable with a proximal end surface of the connection sleeve to place the suture cinch in a locked position.
