A method of making a self-sealing patch for a tissue expander implant includes providing a first sheet having a first sheet outer perimeter and a first sheet inner edge defining a first central opening, providing a second sheet having a second sheet outer perimeter and a second sheet inner edge defining a second central opening, aligning the first and second sheet outer perimeters and the first and second sheet inner edges, capturing an outer washer between the first and second sheet outer perimeters for attaching the first and second sheets together, and capturing an inner washer between the first and second sheet inner edges for attaching the first and second sheets together. The method includes spacing an inner perimeter of the outer washer from an outer perimeter of the inner washer to form a sealed annular space between the attached first and second sheets, and disposing a hydrophobic material within the sealed annular space.

Methods of making self-sealing patches for tissue expander implants

Disclosed is a self-sealing patch for use with a tissue expander implant. The self-sealing patch serves as protection for the tissue expander against a hypodermic needle inadvertently missing a fluid injection port thereof by sealing a puncture through the patch. The patch includes a first sheet having a first sheet perimeter, a second sheet having a second sheet perimeter attached to the first sheet perimeter to form a pocket between the first sheet and the second sheet. Material is disposed within the pocket, where the material is hydrophobic material having a viscosity high enough that the material is prevented from flowing outside the pocket when either the first or second sheet is punctured with a hypodermic needle but low enough that the material flows to close a track made by a hypodermic needle puncturing the first or second sheet.

Tissue expander implant with self-sealing safety patch

Methods for defatting omentum and processes for preparing an acellular omentum, i.e., devitalized or decellularized omentum, comprising extracellular matrix for implantation into a mammalian system. Constructs for medical applications comprising decellularized omentum are also described. More specifically, mesh reinforced omentum biomatrix for soft tissue repair is described.
