Hemostatic devices and methods of use
An anchorage device is provided that is configured to surround an implantable medical device. The anchorage device includes a substrate having a hemostatic agent and an active pharmaceutical ingredient selectively positioned on the substrate. Kits, systems and methods are disclosed.
1. A hemostatic device comprising:
a biodegradable sheet made from a first hemostatic agent, the sheet comprising only one piece; and
a second hemostatic agent selectively positioned on the sheet such that the sheet comprises a plurality of first portions that each include the second hemostatic agent and are spaced apart from one another by a second portion of the sheet that does not include the second hemostatic agent.
2. The hemostatic device recited in claim 1 , wherein the second hemostatic agent is selectively positioned on the sheet such that the second hemostatic agent is targeted to a location of blood loss of a patient.
3. The hemostatic device recited in claim 1 , wherein the sheet comprises opposite top and bottom surfaces, the second hemostatic agent being positioned on the bottom surface.
4. The hemostatic device recited in claim 1 , wherein the sheet comprises opposite top and bottom surfaces, the second hemostatic agent being positioned on the bottom surface and is spaced apart from the top surface.
5. The hemostatic device recited in claim 1 , wherein the second hemostatic agent is positioned about a perimeter of the sheet.
6. The hemostatic device recited in claim 1 , wherein the second hemostatic agent is positioned about an entire perimeter of the sheet and is spaced apart from an interior portion of the sheet.
7. The hemostatic device recited in claim 1 , wherein the second hemostatic agent is selectively positioned on one side of the sheet and an active pharmaceutical ingredient is selectively positioned on an opposite second side of the sheet, the second side being free of the second hemostatic agent.
8. The hemostatic device recited in claim 7 , wherein the active pharmaceutical ingredient is selected from a group consisting of anesthetics, antibiotics, anti-inflammatory agents, procoagulant agents, fibrosis-inhibiting agents, anti-scarring agents, leukotriene inhibitors/antagonists, cell growth inhibitors and mixtures thereof.
9. The hemostatic device recited in claim 1 , wherein the second hemostatic agent is selected from a group consisting of epinephrine, tranexamic acid, chitosan and oxidized regenerated cellulose.
10. The hemostatic device recited in claim 1 , wherein the second hemostatic agent is selectively positioned on opposite first and second sides of the sheet and an active pharmaceutical ingredient is selectively positioned on at least one of the sides of the sheet.
11. The hemostatic device recited in claim 1 , wherein the sheet comprises a first portion and a second portion, the second hemostatic agent being selectively positioned on the first portion, an active pharmaceutical ingredient being selectively positioned on the second portion.
12. The hemostatic device recited in claim 11 , wherein the active pharmaceutical ingredient is selected from the group consisting of rifampin and minocycline and mixtures thereof.
13. The hemostatic device recited in claim 1 , wherein:
the first hemostatic agent is collagen; and
the sheet is made entirely from the first hemostatic agent.
14. The hemostatic device recited in claim 1 , further comprising a polymer that is applied to the sheet, the polymer comprising the second hemostatic agent.
15. The hemostatic device recited in claim 14 , wherein the polymer is selected from a group consisting of polylactic acid, polyglycolic acid, poly(L-lactide), poly(D,L-lactide)polyglycolic acid[polyglycolide], poly(L-lactide-co-D,L-lactide), poly(L-lactide-co-glycolide), poly(D, L-lactide-co-glycolide), poly(glycolide-co-trimethylene carbonate), poly(D,L-lactide-co-caprolactone), poly(glycolide-co-caprolactone), polyethylene oxide, polydioxanone, polypropylene fumarate, poly(ethyl glutamate-co-glutamic acid), poly(tert-butyloxy-carbonylmethyl glutamate), polycaprolactone, polycaprolactone co-butylacrylate, polyhydroxybutyrate, copolymers of polyhydroxybutyrate, poly(phosphazene), poly(phosphate ester), poly(amino acid), polydepsipeptides, maleic anhydride copolymers, polyiminocarbonates, poly[(97.5% dimethyl-trimethylene carbonate)-co-(2.5% trimethylene carbonate)], poly(orthoesters), tyrosine-derived polyarylates, tyrosine-derived polycarbonates, tyrosine-derived polyiminocarbonates, tyrosine-derived polyphosphonates, polyethylene oxide, polyethylene glycol, polyalkylene oxides, hydroxypropylmethylcellulose, polysaccharides, hyaluronic acid, chitosan, regenerate cellulose and mixtures thereof.
16. A hemostatic device comprising:
a sheet consisting of a first hemostatic agent, the first hemostatic agent being selected from the group consisting of collagen, epinephrine, tranexamic acid, chitosan and cellulose;
a second hemostatic agent selectively positioned on the sheet such that the substrate comprises a plurality of first portions that each include the second hemostatic agent positioned thereon and are spaced apart from one another by a second portion of the sheet that does not include the second hemostatic agent positioned thereon; and
an active pharmaceutical ingredient selectively positioned on the sheet.
17. The hemostatic device recited in claim 16 , wherein the active pharmaceutical ingredient is selectively positioned on the sheet such that active pharmaceutical ingredient is targeted to a location to treat at least one condition when the sheet is applied to the patient.
18. The hemostatic device recited in claim 16 , wherein the active pharmaceutical ingredient is selectively positioned on the sheet such that active pharmaceutical ingredient is targeted to a location to provide pain relief, inhibit scarring or fibrosis and/or inhibit bacterial growth.
19. A hemostatic device comprising:
a biodegradable sheet made from a first hemostatic agent; and
a second hemostatic agent selectively positioned on the sheet such that the sheet comprises a plurality of first portions that each include the second hemostatic agent and are spaced apart from one another by a second portion of the sheet that does not include the second hemostatic agent,
wherein the first hemostatic agent is collagen and the sheet is made entirely from the first hemostatic agent.
20. The hemostatic device recited in claim 19 , further comprising a polymer that is applied to the sheet, the polymer comprising the second hemostatic agent.
