Abstract

A device for spraying a biological substance onto a biocompatible implant. The device includes a housing that defines a sterile chamber. A spray head is within the chamber and proximate to a first end. A first conduit is configured to direct the biological substance into the chamber through a first spray tip of the spray head. A second conduit is configured to direct an activator into the chamber through a second spray tip of the spray head. A third conduit is configured to direct compressed air to the chamber through a third spray tip of the spay head. The spray head is configured to direct a coating of the biological substance as activated by the activator to the implant seated within the chamber at a second end that is opposite to the first end.

First claim

What is claimed is:

1. A method for sterilely spraying a biological substance onto an implant comprising:
connecting a first syringe including the biological substance to a first connector proximate to a first conduit that extends to a first spray tip of a spray head mounted within a housing, the housing defining a chamber having a first end, a second end, and a sidewall having a threaded portion, the sidewall extending between the first end and the second end;
connecting a second syringe including an activator of the biological substance to a second connector at a second conduit that extends to a second spray tip of the spray head that is spaced apart from the first spray tip;
connecting an air compressor line to a third connector at a third conduit that extends to a third spray tip of the spray head that is spaced apart from both the first spray tip and the second spray tip, and activating an air compressor to introduce compressed air into the housing through the third spray tip;
simultaneously compressing the first syringe including the biological substance and the second syringe including the activator to introduce the biological substance into the housing through the first spray tip and to introduce the activator into the housing through the second spray tip, the biological substance is activated by the activator upon entering the chamber;
coating the implant seated within the housing with the activated biological substance, which is provided as a spray upon being exposed to the compressed air at the spray head;
separating the first end of the chamber from the second end of the chamber via the threaded portion; and
removing the coated implant from the housing.

2. The method of claim 1 , further comprising connecting a first plunger of the first syringe to a second plunger of the second syringe to simultaneously compress the syringes.

3. The method of claim 1 , wherein the implant is coated with the activated biological substance outside a sterile operating room field by a non-sterile person and the chamber is separated by the non-sterile person, wherein the implant is removed from the housing by a sterile person.

4. The method of claim 1 , further comprising coating a mesh implant sitting atop a support surface spaced from the second end of the housing with the activated biological substance.

5. The method of claim 4 , further comprising delivering the activated biological substance through the mesh implant and through the support surface having a plurality of openings to permit passage of the activated biological material therethrough to coat a first surface of the mesh implant.

6. The method of claim 4 , further comprising delivering the activated biological substance through the mesh implant to permit passage of the activated biological material therethrough to coat a first surface and a second lower surface.

7. The method of claim 1 , further comprising providing the housing with the implant positioned within the chamber in a sterile condition.

8. A method for sterilely spraying a biological substance onto an implant comprising:
delivering a biological substance through a first spray tip into a chamber of a housing having a first portion and a second portion and housing the implant, the first portion separable from the second portion via a threaded portion;
delivering an activator of the biological substance through a second spray tip into the chamber;
delivering compressed air through a third spray tip into the chamber;
coating the implant that is seated within the housing with the activated biological substance, which is provided as a spray upon being exposed to the compressed air; and
separating the first portion from the second portion by unthreading the first portion of the housing relative to the second portion via the threaded portion of the housing to expose the implant.

9. The method of claim 8 , wherein delivering the biological substance includes connecting a first syringe having the biological substance to a first connector that is in communication with the first spray tip and connecting a second syringe having the activator of the biological substance to a second connector in communication with the second spray tip.

10. The method of claim 8 , wherein delivering compressed air further includes connecting an air compressor line to a third connector in communication with the third spray tip to introduce the compressed air into the housing.

11. The method of claim 8 , wherein delivering the biological substance and delivering the activator of the biological substance occurs simultaneously.

12. The method of claim 8 , wherein the implant is coated with the activated biological substance outside a sterile operating room field by a non-sterile person and the first portion is separated from the second portion by the non-sterile person, the method further comprising removing the implant from within the housing by a sterile person.

13. The method of claim 8 , wherein coating the implant further includes coating a mesh implant positioned on a support surface spaced away from an end of the housing.

14. The method of claim 13 , further comprising applying the activated biological material through the mesh implant and through openings in the support surface.

15. A method for sterilely spraying a biological substance onto an implant comprising:
connecting a first source of the biological substance to a housing defining a chamber housing the implant, the chamber having a first end, a second end, and a sidewall having a threaded portion, the sidewall extending between the first end and the second end;
connecting a second source of an activator of the biological substance to the housing;
connecting a source of compressed air to the housing to deliver the compressed air into the housing;
simultaneously delivering the biological substance and the activator into the housing to activate the biological substance;
coating the implant seated within the housing with the activated biological substance;
separating the first end of the chamber from the second end of the chamber via the threaded portion; and
removing the coated implant from the housing.

16. The method of claim 15 , further comprising removing the coated implant from the housing by separating a first portion of the housing from a second portion of the housing.

17. The method of claim 15 , wherein connecting the first source and the second source to the housing includes connecting a first syringe and a second syringe to the housing, respectively.

18. The method of claim 15 , wherein coating the implant further includes coating the implant positioned atop a support surface spaced apart from an end of the housing.

19. The method of claim 15 , wherein coating the implant with the activated biological substance occurs outside a sterile operating room field by a non-sterile person, and separating the first end from the second end is done by the non-sterile person, wherein removing the implant from within the housing is done by a sterile person located inside the sterile operating room field.
