Abstract

The disclosure contemplates a device for cinching surgical sutures, an applicator for applying the device, a dispenser for dispensing the device, an endoscopic kit including the above and a method of use for the same.

Claims

1. Device for cinching surgical sutures, which comprises:

a) first generally elongated member defining a generally longitudinal axis; and

having a generally elongated neck portion having a distal end and a proximal end, and a head portion connected to the distal end of the neck portion, the head portion, the head portion having at least two extension flanges and

b) second generally elongated member defining a generally longitudinal axis and positionable at least partially within the first member with the generally longitudinal axis in alignment with the axis of the first member, the first member movable between a first position which permits reception of a surgical suture between the first and second member in a direction generally transverse to the longitudinal axis and a second position in engagement with wherein said at least two extension flanges are the second member which cinches the suture between the first and second members.

2. The device for cinching surgical sutures according to claim 1 wherein the second member comprises an elongated neck portion having a proximal end and a distal end, a pair of locking legs connected to the proximal end of the neck portion for engaged reception by the first member, and a suture cinching head connected to the distal end of the neck portion for cinched reception of a surgical suture between the cinching head and the first member.

3. The device for cinching surgical sutures according to claim 2 wherein the head portion of the first member defines a generally annular shaped member having an inner open aperture for engaged reception of at least a portion of the head portion of the first member and at least two extensions at distal end which define at least two surface portions which generally complement corresponding respective surface portions on said second member to facilitate the engaged reception of the first member with the second member with the suture therebetween.

4. The device for cinching surgical sutures according to claim 3 wherein the neck portion of the first member defines at least two generally elongated opposed slots extending in the longitudinal direction and dimensioned for reception of corresponding opposed depending flange members of an applicator for applying the suture cinching device, the flanges being dimensioned for engaged reception by the leg portions of the second member for positioning the suture cinching device on the applicator for application to body tissue.

5. The device for cinching surgical sutures according to claim 4 wherein the suture cinching head of the second member is dimensioned for reception within an annular wall portion of the first member for cinching the suture therebetween.

6. The device for cinching surgical sutures according to claim 5 wherein the cinching head of the second member comprises a disc shaped member defining opposed spaces at the periphery thereof for reception of correspondingly configured and dimensioned locator extensions positioned on the first member.

7. The device for cinching surgical sutures according to claim 6 wherein the first and second members are formed of a bioabsorbable material.

8. Apparatus for cinching surgical sutures in a surgical procedure which comprises:

a) a suture cinching device including;

i) a first generally elongated suture cinching member defining a generally longitudinal axis; and

ii) a second generally elongated suture cinching member defining a generally longitudinal axis and positionable at least partially within the first suture cinching member with the generally longitudinal axis in alignment with the axis of the first suture cinching member, the first suture cinching member movable between a first position which permits reception of a surgical suture therebetween in direction generally transverse to the longitudinal axes in a second position in engagement with the second member in which the suture is cinched therebetween;

b) an applicator having a handle portion and an elongated tubular portion connected to the handle portion, the tubular portion having a distal end defining an opening for reception of the first and second members in relative spaced position for reception of the suture therebetween; and

c) an actuating system in the applicator for advancing the first member distally toward the second member to cinch the suture when positioned therebetween and extending in a direction generally transverse to the longitudinal axis of the first and second members, the actuating system being further adapted to eject the first and second members from the distal end of the applicator upon completion of the suture cinching procedure.

9. The apparatus for cinching surgical sutures according to claim 8 further comprising at least one suture.

10. The apparatus for cinching surgical sutures according to claim 8 wherein the suture cinching device is made of a bioabsorbable material.

11. A kit for cinching surgical sutures in surgical procedures, which comprises:

a) at least one dispenser containing a plurality of suture cinching devices for dispensing, each suture cinching device including;

i) a first generally elongated member defining a generally longitudinal axis; and

ii) a second generally elongated member defining a generally longitudinal axis and positionable at least partially within the first member, with the generally longitudinal axis in alignment with the axis of the first member, the first member movable from a first position which permits reception of a surgical suture therebetween in the direction generally transverse to the longitudinal axis and a second position in engagement with the second member which cinches the suture therebetween;

b) an applicator having a handle portion and an elongated portion connected to the handle portion, the elongated portion having a distal end defining an opening for reception of the first and second members in relatively spaced relation; and

c) an actuating system in the applicator for displacing the first member toward the second member to cinch the suture when positioned therebetween and extending in the direction generally transverse to the longitudinal axes of the first and second members, the actuating system being further adapted to eject the first and second members from the distal end of the applicator upon completion of the suture cinching procedure.

12. The kit according to claim 11 further comprising a package containing at least one such applicator and at least one such dispenser, the package having a protective cover for protecting and displaying the applicator and the at least one dispenser.

13. The kit according to claim 11 wherein said package contains at least three of said dispensers.

14. The kit according to claim 11 wherein the suture cinching devices are made of a bioabsorbable material.

15. The kit according to claim 11 further comprising a supply of surgical sutures.
