PATCH FOR REGENERATING BIOLOGICAL TISSUES AND METHOD FOR PRODUCING SAME

Abstract

Patch (1) for regenerating biological tissues in patients and method of manufacture associated with the same, comprising a collagen membrane (2) which comprises cells with a regenerative character; and at least one reinforcement element (3a, 3b) configured to increase the rigidity of said membrane (2), preventing the deformation of said membrane (2) during the handling thereof; wherein said reinforcement element (3a, 3b) can be a perimeter frame (3a) and/or a crossed attachment (3b) between the ends of said membrane (2); which provides a patch (1) which can be applied to any type of biological organ with maximum assurances of success as well as reducing the application time.

3. The patch (1) according to any of the preceding claims, characterised in that said at least one reinforcement element (3a, 3b) comprises a crossed attachment (3b) between ends of said membrane (2).

4. The patch (1) according to any of the preceding claims, characterised in that said at least one reinforcement element (3a, 3b) is manufactured with the same material as said membrane (2).

5. A method of manufacturing a patch (1) for regenerating biological tissues in patients, characterised in that it comprises the following steps: a) manufacturing a collagen membrane (2); b) manufacturing at least one reinforcement element (3a, 3b); c) placing said at least one reinforcement element (3a, 3b) with respect to said membrane (2); d) sterilising the membrane; and e) adding cells with a regenerative character on said membrane (2).

6. The method of manufacturing a patch (1) according to claim 5, characterised in that subsequent to step c) and prior to step e), the assembly formed by the collagen membrane (2) and said at least one reinforcement element (3a, 3b) are sterilised.

7. The method of manufacturing a patch (1) according to any of claims 5 and 6, characterised in that in step c), placing said at least one reinforcement element (3a, 3b) with respect to said membrane (2) is carried out in two sub steps: c1) wetting the membrane (2); and c2) irradiating the membrane (2) and the reinforcement element (3a, 3b) by means of gamma radiation.

8. The method of manufacturing a patch (1) according to any of claims 5 and 6, characterised in that the steps a) and b) of manufacturing the membrane (2) and said at least one reinforcement element (3a, 3b) are carried out in one single step since said at least one reinforcement element (3a, 3b) is part of the membrane (2) itself and both entities being collagen; and wherein the step c) of placing said at least one reinforcement element (3a, 3b) with respect to said membrane (2) is carried out bending at least one of the borders of said membrane (2).

9. The method of manufacturing a patch (1) according to any of claims 5 to 8, characterised in that steps a) and b) of manufacturing the membrane (2) and said at least one reinforcement element (3a, 3b) are carried out in one single step since said at least one reinforcement element (3a, 3b) is part of the membrane (2) itself and both entities being collagen; and wherein the step c) of placing said at least one reinforcement element (3a, 3b) with respect to said membrane (2) is carried out by folding at least a portion of the internal surface of said membrane (2).

Description

DESCRIPTION OF THE DRAWINGS

[0030] In order to complement the description being given and with the aim of aiding a better understanding of the features of the invention, according to a preferred exemplary embodiment of the same, as an integral part of said description, a drawing is included wherein the following has been represented in an illustrative and non-limiting manner:

[0031] FIG. 1 shows a three-dimensional view of the patch for regenerating biological tissues in patients object of the invention, being ensured by surgical material.

PREFERRED EMBODIMENT OF THE INVENTION

[0032] FIG. 1 shows a patch (1) for regenerating biological tissues in patients object of the invention comprising: [0033] a collagen membrane (2) with a plurality of cells with a regenerative character; and [0034] two reinforcement elements (3a, 3b), each one configured to increase the rigidity of said membrane (2), preventing the deformation of said membrane (2) during the handling thereof.

[0035] Said reinforcement elements (3a, 3b) are defined by a perimeter frame (3a) with respect to said membrane (2); and by a pair of crossed attachments (3b) between the ends of said membrane (2); which increase the structural rigidity of the entire patch (1) in a highly effective manner since said reinforcement elements (3a, 3b) are manufactured with the same collagen material as said membrane (2), simplifying to a large extent the installation process thereof during surgery.

[0036] In this respect, the preferred methods of manufacture of the patch (1) for regenerating biological tissues in patients, comprise the following steps: [0037] a) manufacturing the collagen membrane (2) and the reinforcement elements (3a, 3b); [0038] b) placing and generating said reinforcement elements (3a, 3b) with respect to said membrane (2). In which the step b) of placing said reinforcement elements (3a, 3b) with respect to said membrane (2) is carried out by bending each one of the borders of said membrane (2) in order to implement the perimeter frame (3a); and each one of the crossed attachments (3b) is carried out by folding a portion of the internal surface of said membrane (2); [0039] c) sterilising the assembly formed by the membrane (2) and the reinforcement elements (3a, 3b); and lastly [0040] d) adding cells with a regenerative character on said membrane (2).

[0041] In light of the present description and figure, a person with skill in the art could understand that the embodiments of the invention described can be combined in multiple manners within the object of the invention. The invention has been described according to some preferred embodiments of the same, but for the person with skill in the art it will be evident that there can be multiple variations made in said preferred embodiments without departing from the object of the claimed invention.
