SHAPED UMBILICAL CORD TRANSPLANT PRODUCT

摘要

A shaped transplant product 10 derived from human umbilical cord 2 has a collagenous tissue membrane 20 derived from an umbilical cord 2 made essentially of thick collagenous tissue which is shaped to form a soft tissue barrier or wound covering or other internal or external wound healing attachment. The shaped transplant product 10S has a defined memory shape that can be configured to pass through a hollow cylindrical trocar or arthroscopy device for implantation. The defined memory shape can be a hollow elongated split tube. The split tube along the split can have abutting edges. The split tube can have an open split forming a gap between edges adjacent the open slit. The split tube can have overlapping edges. The split tube can have an elongated body having a center portion tapering toward opposing smaller ends to form a pre-set shape.

主权项

1. A shaped transplant product derived from human umbilical cord comprising:
a collagenous tissue membrane derived from an umbilical cord, configured as a soft tissue barrier or wound covering or other internal or external wound healing attachment, wherein the collagenous tissue membrane is shaped during manufacture to have a defined memory retained shape wherein the defined memory retained shape is a hollow cylindrically shaped wall of the collagenous tissue membrane formed as a hollow elongated split tube having ends defining a length of the split tube and wherein the hollow elongated split tube has a longitudinal extending slit forming a gap between two opposing edges adjacent the slit extending the length of the split tube configured to open and pass blood or nerve vessels inside the walls of the collagenous tissue membrane wherein the cut collagenous tissue membrane has a plurality of suture entry sites, the suture entry sites formed integrally in the cylindrically shaped wall along the two opposing edges adjacent the slit, each suture entry site has a structurally enhanced peripheral wall adjacent a thin center surrounded by the peripheral wall thickened relative to the cylindrically shaped wall of the split tube that acts and performs like a grommet but without any additional reinforcements, wherein the hollow elongated split tube along the split forming the gap is configured to close allowing the two opposing edges to abut when sutured wherein each of the plurality of suture entry sites is formed by a heated tip that forms the peripheral wall thickened and toughened creating the structurally enhanced peripheral wall encircling each of the suture entry sites.
