Abstract

The present disclosure includes systems and a method for in situ application of a surgical patch during minimally invasive surgery. The method includes the steps of inserting a surgical patch into a bag; transferring a polymeric bag containing a hemostatic patch into a body cavity; removing the surgical patch from the polymeric bag while the polymeric bag is within the body cavity; and applying the surgical patch to a tissue within the body cavity.

First claim

What is claimed is:

1. A method for in situ application of a surgical patch during minimally invasive surgery, the method comprising the steps of:
providing a surgical patch comprising:
a substrate having a first hydrogel precursor applied to a first portion of the substrate; and
a second hydrogel precursor applied to a second portion of the substrate;

inserting the surgical patch into a polymeric bag;
transferring the polymeric bag containing the surgical patch into a body cavity;
removing the surgical patch from the polymeric bag while the polymeric bag is within the body cavity; and
applying the surgical patch to a tissue within the body cavity by orienting the second portion of the substrate having the second hydrogel precursor closer to the tissue and the first portion of the substrate having the first hydrogel precursor further from the tissue.

2. A method according to claim 1 , further comprising the step of providing a polymeric bag comprising a material selected from the group consisting of polyurethane and latex.

3. The method according to claim 1 further including the step of:
creating hemostasis along the tissue by dissolving the second hydrogel precursor with physiological fluid and allowing the fluid to migrate through the surgical path towards the first portion thereby contacting the first hydrogel precursor, wherein the first and second hydrogel precursors react to form a biocompatible cross-linked material.

4. A method for inserting a surgical patch into a body cavity, the method comprising the steps of:
providing a surgical patch comprising:
a substrate having a first hydrogel precursor applied to a first portion of the substrate; and
a second hydrogel precursor applied to a second portion of the substrate;

transferring a surgical patch into a polymeric bag; and
laparoscopically inserting the polymeric bag containing the surgical patch, into a body cavity by orienting the second portion of the substrate having the second hydrogel precursor closer to a tissue of the body cavity.

5. A method according to claim 4 , further comprising providing a polymeric bag comprising a material selected from the group consisting of polyurethane and latex.
