Abstract
The present invention relates to an innovative biological prostheses, equipped with a drainage system, designed for all surgical applications where there is any risk of hematomas or seromas, which not only allows to minimize adverse events arising from its application, but allows also to improve the effectiveness of the functional reconstruction. The prosthesis of the present invention is a surgical prosthesis made of animal derived collagen having a peripheral outline and a drainage portion comprising a plurality of drainage holes which are located in one or more independent groups each of which has a regular body-centered polygon layout.
Core Innovation
The invention relates to a prosthesis for surgery made of animal derived collagen. The prosthesis has a peripheral perimeter and a drainage portion within the perimeter, and the drainage portion includes a plurality of drainage holes arranged for draining biological surgical sites.
The drainage holes are organized in one or more groups, where each group follows a regular body-centered polygon layout. Each group consists of a single hole at a center of the regular body-centered polygon and holes disposed at vertices of the regular body-centered polygon surrounding the single hole, without additional holes between the center hole and the vertex holes or radially outward of the vertex holes.
Each group of drainage holes is independent such that each group does not share any hole with any other group. The described embodiments emphasize a peripheral outline and a drainage portion designed to improve drainage of hematoma and seroma.
Claims Coverage
Two independent claims define the claimed prosthesis structure, and both specify the core drainage-hole grouping as regular body-centered polygon layouts with independent hole groups. The claims establish the animal derived collagen prosthesis with a peripheral perimeter and drainage portion, grouped drainage holes with a center hole and vertex holes only, and independence between groups with no shared holes.
Animal derived collagen prosthesis with peripheral perimeter and drainage portion
A prosthesis for surgery consisting of animal derived collagen having a peripheral perimeter and a drainage portion within the perimeter provided with a plurality of drainage holes.
Regular body-centered polygon hole group with center hole and vertex holes only
The holes are placed in one or more groups, and each group has a regular body-centered polygon layout, wherein each group consists of a single hole at a center of the regular body-centered polygon and holes disposed at vertices of the regular body-centered polygon surrounding the single hole without further holes between the single hole and the holes disposed at the vertices and without further holes radially outward of the holes disposed at the vertices.
Independent drainage hole groups with no shared holes
Each group of holes is independent, such that each group does not share any hole with any other group.
Regular body-centered polygon hole group with vertex-surrounded center and only surrounding holes
The holes are placed in one or more groups, and each group has a regular body-centered polygon layout, wherein each group consists of a single hole at a center of the regular body-centered polygon and holes disposed at vertices of the regular body-centered polygon surrounding the single hole, wherein the holes disposed at the vertices are the only holes that surround the single hole.
Across independent claim coverage, the prosthesis is defined by animal derived collagen with a peripheral perimeter and a drainage portion containing a plurality of drainage holes. The inventive structure is one or more independent groups, each group having a regular body-centered polygon layout with one center hole surrounded by vertex holes only, and with no shared holes between groups.
Stated Advantages
Improved mechanical fastening due to a non-perforated edge outline zone near the peripheral outline.
Improved drainage performance for fluid accumulation associated with hematoma and seroma.
Documented Applications
Draining biological surgical prosthesis to address hematoma and seroma.
