Abstract

A medical device for repairing soft tissue is disclosed. The medical device includes a cannulated probe positionable a tear in the soft tissue and a stop. The cannulated probe has an inlet about a proximal end and at least one outlet about a distal end with a lumen therethrough. The inlet is operatively connectable to an adhesive source to receive the adhesive therein. The outlet(s) is/are positionable about the tear to emit the adhesive about the tear. The stop is disposable about a periphery of the probe a distance from the inlet, and is positionable adjacent a surface of the soft tissue to terminate advancement of the cannulated probe into the soft tissue whereby a delivery portion of the cannulated probe is positionable about the soft tissue to deliver the adhesive about the tear.

First claim

What is claimed is:

1. A medical device for repairing soft tissue, comprising:
a cannulated probe formed from a single tubular wall defining a periphery of the cannulated probe and a single lumen therethrough, the cannulated probe positionable about a tear in the soft tissue, the single tubular wall of the cannulated probe forming a needle configured to penetrate tissue at a distal end, the single tubular wall having an inlet at a proximal end and at least one outlet about the distal end with the single lumen therethrough, the inlet connected to an adhesive source to receive an adhesive therein and deliver the adhesive through the single lumen to the at least one outlet, the at least one outlet positionable about the tear to emit the adhesive about the tear;
a stop adjustably disposed about a periphery of the single tubular wall of the cannulated probe a distance from the inlet, the stop terminating advancement of the cannulated probe into the soft tissue and preventing further insertion when a delivery portion of the cannulated probe is positioned about the soft tissue to deliver the adhesive about the tear; and
a v-shaped clip comprising an upper plate and a lower plate hingedly connected to the upper plate to define an opening to receive the soft tissue therein and grasp the soft tissue therebetween, wherein the upper plate is configured to fit over a planar surface of the soft tissue having the tear and the lower plate is configured to fit over an opposing planar surface of the soft tissue opposite the tear to secure the opposing planar sides of the tissue, the cannulated probe disposable through the v-shaped clip,
wherein the single lumen extends the length of the single tubular wall of the cannulated probe between the inlet and the outlet.

2. The medical device of claim 1 , wherein the at least one outlet is a distance from the proximal end.

3. The medical device of claim 1 , wherein the at least one outlet comprises a plurality of side ports at various distances from the proximal end.

4. The medical device of claim 3 , wherein the plurality of side ports are angled.

5. The medical device of claim 1 , wherein the cannulated probe is rigid.

6. The medical device of claim 1 , wherein the cannulated probe is flexible.

7. The medical device of claim 1 , wherein the lumen is flexibly shapeable about the soft tissue.

8. The medical device of claim 1 , wherein the cannulated probe has a tip insertable into the tear.

9. The medical device of claim 1 , wherein the stop extends radially about the cannulated probe to define a support disposable about the surface of the soft tissue.

10. The medical device of claim 1 , wherein the stop defines a penetration depth of the delivery portion of the cannulated probe.

11. The medical device of claim 10 , wherein the penetration depth is configured to span positions of the soft tissue on either side of the tear.

12. The medical device of claim 1 , wherein the stop is shaped to cover the tear and seal the adhesive therein.

13. The medical device of claim 1 , further comprising a fiber optic cable disposable through the lumen.

14. The medical device of claim 1 , wherein:
the stop forms an external diameter around the tubular wall of the probe; and
the stop is adjustable to extend radially from the tubular probe at an angle such that the stop is flush with a surface of the tissue.

15. A method of repairing soft tissue, comprising:
providing the medical device of claim 1 ;
inserting the cannulated probe into the soft tissue;
passing the adhesive through the lumen and into the tear; and
retracting the cannulated probe from the soft tissue.

16. A system for repairing soft tissue, comprising:
an adhesive stored in an adhesive source; and
a medical device, comprising:
a cannulated probe formed from a single tubular wall defining a periphery of the cannulated probe and a single lumen therethrough, the cannulated probe positionable about a tear in the soft tissue, the single tubular wall of the cannulated probe forming a needle configured to penetrate tissue at a distal end, the single tubular wall having an inlet at a proximal end and at least one outlet about the distal end with the single lumen therethrough, the inlet connected to the adhesive source to receive the adhesive therein and deliver the adhesive through the single lumen to the at least one outlet, the at least one outlet positionable about the tear to emit the adhesive about the tear;
a stop adjustably disposed about a periphery of the single tubular wall of the cannulated probe a distance from the inlet, the stop terminating advancement of the cannulated probe into the soft tissue and preventing further insertion when a delivery portion of the cannulated probe is positioned about the soft tissue to deliver the adhesive about the tear; and
a v-shaped clip comprising an upper plate and a lower plate hingedly connected to the upper plate to define an opening to receive the soft tissue therein and grasp the soft tissue therebetween, wherein the upper plate is configured to fit over a planar surface of the soft tissue having the tear and the lower plate is configured to fit over an opposing planar surface of the soft tissue opposite the tear to secure the opposing planar sides of the tissue, the cannulated probe disposable through the v-shaped clip,
wherein the single lumen extends the length of the single tubular wall of the cannulated probe between the inlet and the outlet.

17. The system of claim 16 , wherein the adhesive comprises at least one of chemical agents selected from the group of anesthetic agents, plasticizing agents, therapeutic agents, buffers, catalysts, fillers, micro particles, adhesion initiators, thickeners, solvents, drugs, medicaments, natural rubbers, synthetic rubbers, stabilizers, pH modifiers, bioactive agents, cross-linking agents, chain transfer agents, fibrous reinforcements, colorants, preservatives, reducing agents, scavenging agents, formaldehydes, and mixtures thereof.

18. The system of claim 16 , wherein the adhesive comprises at least one of polylactide, poylglycolide, polysaccharides, certain proteins, polyesters, polyhydroxyal kanoates, polyalkelene esters, polyamides, polycaprolactone, polyvinyl esters, polyamide esters, polyvinyl alcohols, polyanhydrides and their copolymers, modified derivatives of caprolactone polymers, polytrimethylene carbonate, polyacrylates, polyethylene glycol, polyolefin, engineered materials, hydrogels, photo-curable hydrogels, terminal diols, minerals, and combinations thereof.

19. The system of claim 16 , further comprising a bioabsorbable fiber and a bioabsorbable polymer matrix comprising minerals and therapeutics.

20. A method of repairing soft tissue, comprising:
providing a cannulated probe formed from a single tubular wall defining a periphery of the cannulated probe and a single lumen therethrough, the single tubular wall of the cannulated probe forming a needle configured to penetrate tissue at a distal end, the single tubular wall having an inlet at a proximal end and at least one outlet about the distal end with the single lumen extending the length of the single tubular wall of the cannulated probe between the inlet and the outlet;
providing a v-shaped clip comprising an upper plate and a lower plate hingedly connected to the upper plate to define an opening;
disposing an adjustable stop about a periphery of the single tubular wall of the cannulated probe a distance from the inlet;
placing the upper plate over a first planar surface of the
