Problems solved by technology

[0004] Stiff and poorly conforming conventional mesh: more likely to irritate the wound when stressed, which may lead to increased postoperative pain and discomfort for the patient; and / or may be less likely to adapt rapidly to the mechanics of muscle contraction and abdominal wall tissue during patient activity Sudden changes in behavior, which may lead to mechanical failure of the mesh, inability of the mesh to maintain augmentation, and / or hernia or prolapse recurrence

example 1

[0261] Implantable meshes were prepared using TFP technology as described herein to combine monofilament radial yarns, monofilament helical yarns and Monofilament axial yarns are placed and secured on a dissolvable ground yarn. The radial monofilament yarn and the axial monofilament yarn were made of a copolymer of polytetrahydrofuran and polybutylene terephthalate (TPC), with a diameter of 210 μm, respectively. The helical monofilament yarn is made of polypropylene (PP) and has a diameter of 300 μm. The first threading multifilament yarn and the second threading multifilament yarn were made of 30Tex polyethylene terephthalate (PET). The soluble base yarn is made of non-woven water-soluble polyvinyl alcohol (PVA).

example 2

[0263] Implantable meshes were prepared using TFP technology as described herein to combine monofilament radial yarns, monofilament helical yarns and Monofilament axial yarns are placed and secured on a dissolvable ground yarn. The radial monofilament yarn and the axial monofilament yarn are made of a copolymer of polytetrahydrofuran and polybutylene terephthalate (TPC), with a diameter of 400 μm, respectively. The helical monofilament yarn is made of polypropylene (PP) and has a diameter of 300 μm. The first threading multifilament yarn and the second threading multifilament yarn were made of 30Tex polyethylene terephthalate (PET). The soluble base yarn is made of non-woven water-soluble polyvinyl alcohol (PVA).

example 3

[0265] Implantable meshes are prepared using TFP technology as described herein to combine monofilament vertical yarns, monofilament horizontal yarns, monofilament Filament diagonal yarns and monofilament helical yarns are placed and fixed on a dissolvable ground yarn. Horizontal monofilament yarns, vertical monofilament yarns, and diagonal monofilament yarns were made from copolymers of polytetrahydrofuran and polybutylene terephthalate (TPC), each with a diameter of 210 μm. The helical monofilament yarn is made of polypropylene (PP) and has a diameter of 300 μm. The first threading multifilament yarn and the second threading multifilament yarn were made of 30Tex polyethylene terephthalate (PET). The soluble base yarn is made of non-woven water-soluble polyvinyl alcohol (PVA).

Abstract

The invention provides implants suitable for soft tissue repair. The present disclosure provides implants suitable for hernia or prolapse repair, the implants including an implantable web including acombination of laid yarns and threading yarns and optionally a substrate. Methods of making such implants are also provided.

Description

technical field [0001] The present disclosure relates generally to implants suitable for soft tissue repair, such as hernia or prolapse repair, comprising an implantable mesh comprising a combination of laying and threading yarns and Optionally a ground yarn. Background technique [0002] Conventional surgical meshes have been used during both laparoscopic and open surgery to treat various types of hernias and / or prolapses. [0003] During surgical treatment of a hernia or prolapse, the opening of the defect in tissue may be closed and bridged with a conventional surgical mesh, such as a knitted, braided and / or woven mesh. In conventional surgical patches, the yarns that form the overall structure of the patch are typically tightly knitted, woven, and / or woven together and locked into place with each other. For example, a knitted patch typically comprises yarns that are knitted together in at least the warp and weft directions such that the warp yarns and the weft yarns ar...
