Abstract

A molded suture retainer is provided for retaining and storing long suture lengths. Both absorbable and nonabsorbable sutures fabricated from natural or synthetic materials can be advantageously retained and stored therein. The retainer is characterized by a wide spiraling oval passageway with minimal convolutions covered by a cover sheet. The length of the passageway is preferably proportional to 1/3 to 1/2 the overall length of the suture to be retained therein. In accordance with the method of the invention, sutures are doubled or tripled over and inserted into the retainer under vacuum. Sutures packaged in accordance with the invention exhibit fewer kinks and bends than prior packaged sutures.

Claims

1. A method of leading a suture having a proximal end and a distal end into a suture retainer having a convoluted passageway with a suture receiving section at a proximal end thereof and a central vacuum receiving section at a distal end thereof and a cover sheet with a suture entrance aperture and a vacuum aperture respectively aligning with the suture receiving section and said central vacuum receiving section of the passageway, said method comprising the steps of:

forming a first curved section in said suture about one third down the length of said suture from the proximal end thereof;

forming a second curved section in said suture about two thirds down the length of said suture from the proximal end thereof;

disposing the distal end of said suture adjacent and extending beyond said first curved section;

applying a vacuum to said vacuum aperture;

sequentially feeding said distal suture end and said first curved section through said suture entrance aperture into said passageway under vacuum while holding said proximal end and said second curved section; and

drawing said suture into said passageway until said distal suture end and said first curved section are disposed in said passageway such that said first curved section remains curved while disposed in said passageway and said proximal suture end is adjacent said suture entrance aperture.

2. The method of claim 1 further comprising the step of maintaining said distal suture end adjacent and extending beyond said first curved section as said suture is drawn into said passageway.

3. A method of loading a suture into a suture retainer having a convoluted passageway with a suture receiving section at a proximal end thereof and a central vacuum receiving section at a distal end thereof and a cover sheet with a suture entrance aperture and a vacuum aperture respectively aligning with the suture receiving section and said central vacuum receiving section of the passageway, said method comprising the steps of:

folding said suture, thereby forming a curved section;

applying a vacuum to said vacuum aperture to draw said suture into said passageway;

feeding said curved section through said suture entrance aperture into said convoluted passageway under vacuum drawing said suture into said passageway until curved section of said suture is disposed closest said distal end of said passageway.

4. The method of loading a suture as in claim 3 wherein the step of folding the suture further includes forming a plurality of curved suture sections.

5. The method of loading a suture as in claim 3 wherein said convoluted passageway of said suture retainer is formed in a spiral.

6. The method of loading a suture as in claim 3 wherein said suture includes at least one needle attached to an end thereof.
