Abstract

A suture passer of the type adapted for releasably retaining a suture is disclosed. The suture passer has a handle and an elongate tubular probe guide extending in a distal direction from the handle. The tubular probe guide can be straight or curved. An elongate probe is axially movably disposed within the tubular probe guide, for motion between at least one retracted position and an extended position in which the sharpened distal tip of the probe is exposed. The probe has a recess, which cooperates with an opening on the tubular guide for receiving a suture.

Claims

1. A suture passer of the type adapted for releasably retaining a suture, comprising:

a handle;

an elongate tubular probe guide extending in a distal direction from the handle;

an elongate pointed probe axially movably disposed within the tubular probe guide to facilitate penetration of tissue; and

a recess on the pointed probe and an opening on the tubular probe guide for receiving a suture, wherein the pointed probe is axially movable with respect to the probe guide between a first position in which the recess is aligned with the opening for receiving a suture therein, and a second position wherein the recess is out of alignment with the opening to trap a suture within the recess, wherein the opening comprises a slot having a first segment generally extending axially along a first side of the probe guide, a second segment generally extending axially along a second side of the probe guide, said second side being generally opposite said first side, and a third segment joining said first segment and said second segment, said third segment extending transverse to the longitudinal axis of the probe guide.

2. A suture passer as in claim 1, further comprising a third position so that in a first position the recess is aligned with the opening for receiving a suture and the distal tip of the pointed probe is retracted within the probe guide;

in a second position the recess is out of alignment with the opening and the distal tip of the pointed probe is retracted; and

in a third position the recess is out of alignment with the opening and the distal tip of the pointed probe is extended beyond the probe guide.

3. A suture passer as in claim 2, further comprising a control on the handle for selectively positioning the pointed probe in the first, second, and third positions.

4. A suture passer as in claim 3, further comprising an axially movable actuator pin extending proximally from the pointed probe.

5. A suture passer as in claim 4, wherein the control comprise a rotatable cam having a contoured engagement surface for engaging the actuator pin and holds the actuator pin in a stable position.

6. A suture passer as in claim 5, wherein the engagement surface comprises a ramp which cooperates with the actuator pin and the proximal bias on the pointed probe so that the distal tip of the pointed probe is normally retracted within the distal end of the probe guide, and distally extended beyond the probe guide only during manual manipulation of the control.

7. A suture passer as in claim 6, further comprising an indicium on the control for indicating the axial position of the pointed probe.

8. A suture passer as in claim 7, wherein the indicium comprises the rotational position of the cam.

9. A suture passer as in claim 1, wherein said recess comprises an annular or slotted recess extending radially inwardly about the periphery of the pointed probe.

10. A suture passer as in claim 1, further comprising a spring within the handle for biasing the pointed probe in the proximal direction with respect to the probe guide.

11. A suture passer as in claim 1, wherein the distal end of the probe guide is provided with a blunt atraumatic tip which allows for tactile positioning digitally.

12. A suture passer as in claim 1, wherein said third segment joins the proximal ends of said first and second segments of the opening.

13. The suture passer as in claim 1, in combination with a suture extending through the recess on the pointed probe.

14. A suture passer of the type adapted for releasably retaining a suture, comprising:

a handle;

an elongate, curved tubular guide extending in a distal direction from the handle, the distal end of the guide having a blunt atraumatic tip that allows for tactile positioning;

an elongate, curved probe axially movably disposed within the tubular guide to facilitate penetration of tissue; and

a generally transverse recess on the probe and an opening on the tubular guide for receiving a suture, wherein the probe is axially movable with respect to the guide between a first position in which the recess is aligned with the opening for receiving a suture therein, and a second position wherein the recess is out of alignment with the opening to trap a suture within the recess.

15. A suture passer of the type adapted for releasably retaining a suture, comprising:

a handle;

an elongate tubular probe guide extending in a distal direction from the handle;

an elongate pointed probe axially movably disposed within the tubular probe guide to facilitate penetration of tissue;

a recess on the pointed probe and an opening on the tubular probe guide for receiving a suture, wherein the pointed probe is axially movable with respect to the probe guide between a first position in which the recess is aligned with the opening for receiving a suture therein and the distal tip of the pointed probe is retracted within the probe guide, a second position in which the recess is out of alignment with the opening to trap a suture within the recess and the distal tip of the pointed probe is retracted, and a third position in which the recess is out of alignment with the opening and the distal tip of the pointed probe is extended beyond the probe guide;

an axially movable actuator pin extending proximally from the pointed probe; and

a control on the handle for selectively positioning the pointed probe in the first, second, and third positions, said control comprising a rotatable cam having a contoured engagement surface for engaging the actuator pin and holding the actuator pin in a stable position.

16. A suture passer as in claim 15, wherein the engagement surface comprises a ramp which cooperates with the actuator pin and the proximal bias on the pointed probe so that the distal tip of the pointed probe is normally retracted within the distal end of the probe guide, and distally extended beyond the probe guide only during the manual manipulation of the control.

17. A suture passer as in claim 16, further comprising an indicium on the control for indicating the axial position of the pointed probe.

18. A suture passer as in claim 17, wherein the indicium comprises the rotational position of the cam.
