Abstract
A reinforcing incision drape for tissue, such as fragile tissue, includes an absorbable surgical mesh having top and bottom major surfaces. The absorbable surgical mesh has a stitching zone and first and second reinforcing zones that bound opposite sides of the stitching zone. The stitching zone is less porous and the first and second reinforcing zones are more porous than the stitching zone. A releasable liner covers the top major surface of the absorbable surgical mesh within the stitching zone of the absorbable surgical mesh. A weaker adhesive, such as a pressure sensitive adhesive, covers the bottom major surface of the surgical mesh within the centrally located stitching zone of the absorbable surgical mesh, and a stronger adhesive, such as cyanoacrylite, covers the first and second reinforcing zones of the absorbable surgical mesh.
Core Innovation
The invention relates to a reinforcing incision drape for tissue that uses an absorbable surgical mesh having a top major surface and a bottom major surface opposite the top major surface. In a desired position, the bottom major surface is positioned against tissue to be sutured, and the stitching zone is configured to be stitched to the tissue to be sutured. The absorbable surgical mesh includes a stitching zone and first and second reinforcing zones that bound opposite sides of the stitching zone.
The stitching zone has first structural properties, while the first and second reinforcing zones have second structural properties that differ from the first structural properties. The second structural properties are configured to generate a bond between the reinforcing zones and the tissue to be sutured that is stronger than a bond generated between the stitching zone and the tissue to be sutured. The reinforcing zones and the stitching zone are treated as different bonding regions, with structural properties intended to alter the strength of the resulting bond.
A releasable liner covers the top major surface of the absorbable surgical mesh within the stitching zone. The releasable liner comprises a central section covering the stitching zone and series of first and second laterally extending releasable strips spaced from one another, extending over the first reinforcing zone and over the second reinforcing zone, respectively, to side edges of the absorbable surgical mesh. The strips expose top major surface portions located within the reinforcing zones between adjacent strips, and the reinforcing zones include pores and larger apertures that are covered by the corresponding laterally extending releasable strips.
Claims Coverage
Three independent claims are present: clm-00001, clm-00004, and clm-00011. Across these independent claims, the coverage centers on an absorbable surgical mesh reinforced incision drape with different structural properties in stitching and reinforcing zones, and a releasable liner structure that exposes reinforcing-zone areas while covering stitching-zone top surface.
Stitching-zone versus reinforcing-zone bonding strength using differing structural properties
An absorbable surgical mesh having a stitching zone and first and second reinforcing zones that bound opposite sides of the stitching zone, where the stitching zone has first structural properties and the first and second reinforcing zones have second structural properties configured to generate a bond between the reinforcing zones and the tissue to be sutured that is stronger than a bond generated between the stitching zone and the tissue to be sutured.
Releasable liner with central section and laterally extending strips exposing reinforcing-zone top surface
A releasable liner covering the top major surface of the absorbable surgical mesh within the stitching zone, comprising a central section covering the stitching zone and series of laterally extending releasable strips extending over the first and second reinforcing zones to side edges, wherein the top major surface of the absorbable surgical mesh located within each reinforcing zone is exposed between adjacent ones of the laterally extending releasable strips.
Reinforcing zones with pores and larger apertures covered by the releasable strips
The first reinforcing zone includes a plurality of first pores, the second reinforcing zone includes a plurality of second pores, and the reinforcing incision drape further comprises a first set of apertures within the first reinforcing zone larger than the first pores with the first laterally extending releasable strips covering the first set of large apertures, and a second set of large apertures within the second reinforcing zone larger than the second pores with the second laterally extending releasable strips covering the second set of large apertures.
System for reinforcing tissue using first and second absorbable adhesives and the reinforcing incision drape liner
A system for reinforcing tissue comprising a reinforcing incision drape having a stitching zone and first and second reinforcing zones, a first absorbable adhesive covering the bottom major surface within the stitching zone, a second absorbable adhesive covering the first and second reinforcing zones configured to generate a bond with the tissue to be sutured stronger than a bond between the first absorbable adhesive and the tissue to be sutured, and a releasable liner covering the top major surface within the stitching zone with central and laterally extending releasable strips exposing reinforcing-zone areas.
The independent claims cover a reinforcing incision drape and reinforcing tissue system in which an absorbable surgical mesh defines a stitching zone and first and second reinforcing zones with different structural properties to produce stronger bonds at the reinforcing zones. The releasable liner structure includes a central section and laterally extending strips that cover stitching-zone top surface while exposing reinforcing-zone top surface, with pores and larger apertures in the reinforcing zones covered by the laterally extending strips.
Stated Advantages
A bond between the reinforcing zones and the tissue to be sutured that is stronger than a bond generated between the stitching zone and the tissue to be sutured.
Documented Applications
Reinforcing tissue during suturing by using a reinforcing incision drape configured to place an absorbable surgical mesh against tissue to be sutured.
