Automatically reloading suture passer devices that prevent entanglement
Suture passers and methods of use. Described herein are suture passers preloaded with suture, including cartridges that couple to a suture passer to form a loaded suture passer that are configured to prevent a length of suture (e.g., already-passed suture) from re-entering the channel of the suture passer jaw and getting recaptured and/or entangled by the tissue penetrator. In particular, described herein are preloaded and automatically re-loading suture passers that are adapted to include a gate, guide or shield on one of the jaws of the suture passer, and methods of operating such suture passers for surgical use including repairing tissue.
1. A suture passer comprising: an elongate body extending between a proximal handle end and a distal end; a first and a second jaw coupled to the distal end, the second jaw including; a housing with a suture arranged in a first loop and a second loop housed therein; and a tissue penetrator configured to slide axially in and out of the housing; wherein the housing has a distal opening that receives the tissue penetrator therethrough, and wherein the tissue penetrator is configured to sequentially remove the first and then the second loop of the suture from within the housing; and wherein the second jaw includes a means of inhibiting the first loop from re-entering the distal opening as the tissue penetrator re-enters the housing to engage with the second loop, the means of inhibiting including a gate pin coupled to the second jaw, the first loop wrapped around the gate pin.
2. The suture passer of claim 1 wherein the first loop is preloaded onto the tissue penetrator, and the second loop is proximally arranged relative to the first loop within the housing.
3. The suture passer of claim 1 wherein the suture defines a first and second limb, each limb disposed within the housing.
4. The suture passer of claim 1 wherein the second loop is arranged such that the tissue penetrator automatically loads with the second loop as the tissue penetrator retracts axially.
5. The suture passer of claim 1 wherein the gate pin is disposed adjacent the distal opening and crosses a longitudinal axis of the second jaw.
6. A suture passer comprising: an elongate body extending between a proximal handle end and a distal end; a first and second jaw coupled to the distal end, the second jaw including; a channel extending along the second jaw and defining a distal opening; a tissue penetrator configured to slide axially along the channel; a suture comprising a first bight and a second bight arranged within the channel; and wherein the distal opening is configured to provide passage for the tissue penetrator loaded with either the first or second bight therethrough, and wherein the tissue penetrator is configured to sequentially move the first and then the second bight from within the channel, through the distal opening and towards the first jaw; and wherein a gate pin is coupled to the second jaw, the gate pin engaged with the first bight and configured to inhibit a portion of the first bight of suture from re-entering the distal opening.
7. The suture passer of claim 6 wherein the second bight is arranged such that the tissue penetrator automatically engages the second loop as the tissue penetrator retracts axially.
8. The suture passer of claim 6 wherein the means of inhibiting may include a gate pin has a first end coupled to the second jaw at a first end, and having a free opposing end, the gate pin engaged with the first bight.
9. The suture passer of claim 8 wherein the gate pin is configured to deflect and disengage from the first bight.
10. The suture passer of claim 8 wherein the gate pin is configured to elastically deflect to release the first bight from the channel, and to retract and thereby prevent the first bight from re-entering the distal opening.
11. The suture passer of claim 6 wherein the means of inhibiting includes wrapping a length of the first bight around an outer surface of the second jaw.
