Abstract

A suture-material-dispenser system for a supply of dry or wet suture material includes the supply of such material and a housing which defines a cavity for containing the supply. The housing includes a top region that has an opening formed in it, and a bottom region with a semi-circular bearing positioned in it. A reel fits within the cavity on the bearing, and has wound on it the supply. An anti-contaminant, flip-top cover is pivotably attached to the top region, and is constructed for releasable closure over the top region substantially to prevent contaminants from entering the cavity. A gas-permeable, resilient member is also included and has a body that fits sealingly within the opening, which body has formed in it a suture-material-dispensing port to allow dispensing of suture material therethrough. The body is preferably formed from a substance with a hardness in the range of about 40-80 on a Shore A durometer. An on-board cutter is also attached to the housing adjacent the resilient member for allowing the user to cut a desired dispensed amount of material from such supply. The cover may also include a downwardly extending, elongate pressure applicator with a bottom surface that presses against the resilient member adjacent the port when the cover is closed over the top region. Preferably, the resilient member is formed from a material that is ethylene-oxide-gas permeable, such as liquid-injection-molded silicone.

Claims

1. A suture-material-dispenser system for dry suture material, comprising:

a housing which defines a cavity for containing the suture material, with the housing including a top region that has an opening; and

a resilient member formed from a gas-permeable material, the member having a body that fits sealingly within the opening, the body having a suture-material-dispensing port for allowing the suture material to be dispensed therethrough, the body having a pre-dispense condition and a dispense condition, and the gas-permeable material having a memory characteristic that allows the body adjacent the port to deform when the body is in the dispense condition, thus to minimize degradation of the suture material during dispensing of suture material, and the memory characteristic also allows the body to return substantially to the pre-dispense condition, thus to seal substantially the cavity from contaminant.

2. The system of claim 1 wherein an anti-contaminant, flip-top cover is pivotably attached to the top region, and is constructed for releasable closure over the top region substantially to prevent contaminants from entering the cavity.

3. The system of claim 2 wherein the cover further includes a downwardly extending, elongate pressure applicator with a bottom surface that presses against the resilient member adjacent the port when the cover is closed over the top region.

4. The system of claim 3 wherein the top region includes a lip that extends outwardly from the housing, and the cover includes a downwardly extending expanse that is engageable with the lip to obtain the releasable closure.

5. The system of claim 4 further comprising an on-board cutter attached to the housing adjacent the resilient member for allowing a user to cut a desired dispensed amount of the suture material.

6. The system of claim 2 wherein the top region includes a lip that extends outwardly from the housing, and the cover includes a downwardly extending expanse that is engageable with the lip to obtain the releasable closure.

7. The system of claim 6 further comprising an on-board cutter attached to the housing adjacent the resilient member for allowing a user to cut a desired dispensed amount of the suture material.

8. The system of claim 2 further comprising an on-board cutter attached to the housing adjacent the resilient member for allowing a user to cut a desired dispensed amount of the suture material.

9. The system of claim 3 further comprising an on-board cutter attached to the housing adjacent the resilient member for allowing a user to cut a desired dispensed amount of the suture material.

10. The system of claim 1 further comprising an on-board cutter attached to the housing adjacent the resilient member for allowing a user to cut a desired dispensed amount of the suture material.

11. The system of claim 1 wherein the material of the resilient member is that is ethylene-oxide-gas permeable.

12. The system of claim 1 wherein the body of the resilient member is formed from liquid- injection-molded silicone.

13. The system of claim 1 further comprising a supply of suture material contained in the cavity and a reel is fittable within the cavity, wherein the supply is wound onto the reel and the housing includes a bottom region and a semi-circular bearing positioned in the bottom region for supporting the reel.

14. The system of claim 1 wherein the port is formed as a slit with a length of about 2-6 mm.

15. The system of claim 1 wherein the material of the resilient member has a hardness in a range of about 40-80 on a Shore A durometer.

16. A suture-material-dispenser system for dry suture material, comprising:

a housing which defines a cavity for containing the suture material, with the housing including a top region that has an opening;

an anti-contaminant, flip-top cover pivotably attached to the top region, and being constructed for releasable closure over the top region substantially to prevent contaminants from entering the cavity;

a resilient member formed from a gas-permeable material, the resilient member having a body that fits sealingly within the opening, the body having a suture-material-dispensing port for allowing the suture material to be dispensed therethrough, and the gas-permeable material having a hardness in a range of about 40-80 on a Shore A durometer; and

an on-board cutter attached to the housing adjacent the resilient member for allowing a user to cut a desired dispensed amount of the suture material.

17. The system of claim 16 wherein the cover further includes a downwardly extending, elongate pressure applicator with a bottom surface that presses against the resilient member adjacent the port when the cover is closed over the top region.

18. The system of claim 17 wherein the top region includes a lip that extends outwardly from the housing, and the cover includes a downwardly extending expanse that is engageable with the lip to obtain the releasable closure.
