Abstract

A suture guide includes a first part having a first base piece and a plurality of first needle portions joined to the first base piece. Each first needle portion has a respective first needle portion sidewall. The suture guide further includes a second part having a second base piece and a plurality of second needle portions joined to the second base piece. Each second needle portion has a respective second needle portion sidewall. The first part and second part are moveable between a separated configuration and a joined configuration. In the separated configuration, the first needle portions are spaced away from the second needle portions. In the joined configuration, each one of the first needle portions is positioned adjacent and cooperates with a respective one of the second needle portions to form a needle.

Claims (22)

1. A suture guide comprising:

first suture guide part having a first base piece and a plurality of first needle portions joined to the first base piece, each first needle portion having a respective first needle portion sidewall; and

a second suture guide part having a second base piece and a plurality of second needle portions joined to the second base piece, each second needle portion having a respective second needle portion sidewall;

wherein the first suture guide part and second suture guide part are moveable between a separated configuration and a joined configuration;

wherein in the separated configuration, the plurality of first needle portions are spaced away from the plurality of second needle portions; and

wherein in the joined configuration, each one of the first needle portions is positioned adjacent and cooperates with a respective one of the second needle portions to form a needle, each needle having a respective needle sidewall formed by one of the first needle portion sidewalls and one of the second needle portion sidewalls, and each needle sidewall defining, respectively, a lumen and a pointed tip.

2. The suture guide of claim 1 , wherein:

each first needle portion sidewall defines a respective first needle portion lumen and has a respective first proximal end joined to the first base piece, and a respective opposed first distal end, and

each second needle portion sidewall defines a respective second needle portion lumen and has a respective second proximal end joined to the second base piece, and a respective opposed second distal end.

3. The suture guide of claim 2 , wherein

each first needle portion sidewall defines a respective first opening extending between the first proximal end thereof and the first distal end thereof, and

each second needle portion sidewall defines a respective second opening extending between the second proximal end thereof and the second distal end thereof.

4. The suture guide of claim 2 , wherein when the first suture guide part and the second suture guide part are in the joined configuration, each one of the first needle portion lumens joins with a respective one of the second needle portion lumens to form a respective one of the lumens.

5. The suture guide of claim 1 , wherein

the plurality of first needle portions are arranged linearly along an edge of the first base piece with each first opening facing away from the first base piece, and

the plurality of second needle portions are arranged linearly along an edge of the second base piece with each second opening facing away from the second base piece.

6. The suture guide of claim 1 , wherein the first suture guide part comprises a first engagement member, the second suture guide part comprises a second engagement member, and the first engagement member is releasably securable to the second engagement member to maintain the first suture guide part and the second suture guide part in the joined configuration.

7. The suture guide of claim 1 , wherein

the first base piece comprises a first elongate plate and extends along a first longitudinal axis, and the second base piece comprises a second elongate plate and extends along a second longitudinal axis; and

when the first suture guide part and the second suture guide part are in the joined configuration, the first base piece and second base piece are positioned side-by-side and the first longitudinal axis and second longitudinal axis are parallel.

8. The suture guide of claim 7 , wherein the first base piece comprises a set of notches therein, and the set of notches extend transverse to the first longitudinal axis.

9. The suture guide of claim 1 , wherein when in a transverse section, each first needle portion sidewall and each second needle portion sidewall is semicircular.
