198 results about "Hernia repair" patented technology

Hernia repair refers to a surgical operation for the correction of a hernia—a bulging of internal organs or tissues through the wall that contains it. It can be of two different types: herniorrhaphy; or hernioplasty. This operation may be performed to correct hernias of the abdomen, groin, diaphragm, brain, or at the site of a previous operation. Hernia repair is often performed as an ambulatory procedure.

Method of repairing inguinal hernias

A universal, surgical prosthesis for hernia repair is provided in the form of a foldable sheet. The prosthesis includes a barrier layer formed of a material adapted to prevent biological adherence thereto, such as polytetrafluoroethylene, and a second surface layer formed of a material adapted to promote biological tissue adherence thereto, such as polypropylene. The second surface may be formed of a series of spaced projections. The prosthesis is adapted to be manipulated into an operative position to exhibit an appropriate exterior when in the operative position. In this manner, the universal, surgical prosthesis can be utilized for a wide range of surgical procedures.

Three-dimensional culture of pancreatic parenchymal cells cultured living stromal tissue prepared in vitro

A stromal cell-based three-dimensional cell culture system is prepared which can be used to culture a variety of different cells and tissues in vitro for prolonged periods of time. The stromal cells and connective tissue proteins naturally secreted by the stromal cells attach to and substantially envelope a framework composed of a biocompatible non-living material formed into a three-dimensional structure having interstitial spaces bridged by the stromal cells. The living stromal tissue so formed provides the support, growth factors, and regulatory factors necessary to sustain long-term active proliferation of cells in culture and / or cultures implanted in vivo. When grown in this three-dimensional system, the proliferating cells mature and segregate properly to form components of adult tissues analogous to counterparts in vivo, which can be utilized in the body as a corrective tissue. For example, and not by way of limitation, the three-dimensional cultures can be used to form tubular tissue structures, like those of the gastrointestinal and genitourinary tracts, as well as blood vessels; tissues for hernia repair and / or tendons and ligaments; etc.

Hernia repair mesh prosthesis, and method of using same

A hernia repair prosthetic element includes: a central portion which covers a hernia opening within a patient; plural support portions integrally connected about a periphery of the central portion for securing the central portion in covering relation to the hernia opening; the prosthetic element, including the central and support portions, being a substantially planar member formed of flexible mesh material; the support portions being foldable relative to the central portion so that the prosthetic element can be selectively manipulated between folded and unfolded shapes; the support portions being adapted to securely engage various components of the patient's body surrounding the hernia opening; and openings are formed through the central portion for passage of fluid therethrough. The prosthetic element has only two basic shapes, one for use in relation to all groin hernias and one for use in relation to all abdominal hernias. The flexible mesh material may be of propylene or other suitable materials, the central portion has an enhanced strength, such as being formed of two layers of the mesh material, and the central portion may be stretchable to absorb greater forces imposed thereon.

Method and apparatus for minimally invasive delivery, tensioned deployment and fixation of secondary material prosthetic devices in patient body tissue, including hernia repair within the patient's herniation site

Apparatus and methods enable insertion and tensioned deployment of a secondary material prosthetic device into a body cavity or other tissue of a patient, such as for example hernia repair mesh into the abdominopelvic cavity of a patient through the hernia site. The present invention establishes fixation sites for the prosthetic device and tensions it against the body tissue. It may also be used implant fixation devices within the body tissue so that the prosthetic device is tensioned into firm abutting contact with the body tissue. Instrument deployment and fixation struts may be advanced in retrograde fashion in order to reduce needed deployment volume within the patient's body cavity. The prosthetic device advantageously may be flexibly coupled to the instrument via fixation devices such as sutures, so as to increase orientation flexibility.

Absorbable Synthetic Braided Matrix for Breast Reconstruction and Hernia Repair

A braided, rather than woven, three-dimensional matrix has been developed to provide mechanical support in breast reconstruction or a mastopexy procedure. The braided three-dimensional matrix may be used to assist in hernia repair procedures. The matrix is a supple, strong, and flexible material, that can increase 50% to 100% in size when stretched along the vertical plane, but only extends by about 10% to 20% in length when stretched along the horizontal plane. Although the matrix is degradable, it provides sufficient mechanical and structural support for six to twelve months following implantation to allow for repair or growth of the breast tissue or the abdominal wall. The matrix is formed of three-dimensional braided multifilament polymeric fibers plied to create yarn bundles, and wherein the matrix comprises an inter-connected, open pore structure that enables even and random distribution and in-growth of cells.

Insufflation of body cavities

An apparatus for use in insufflation of a body cavity 5, such as through a trocar 6 is described. One such application is laparoscopic surgery. The device is also suitable for use in any situation involving insufflation of a body cavity such as in arthroscopies, pleural cavity insufflation (for example during thoracoscopy), retroperitoneal insufflations (for example retroperitoneoscopy), during hernia repair, during mediastinoscopy and any other such procedure involving insufflation. The apparatus comprises a reservoir 1 for storing an liquid solution, an aerosol generator 2 for aerosolising the solution, and a controller 3 for controlling operation of the aerosol generator 2. Aerosolised liquid solution (which main contain a pharmaceutical) is entrained with insufflation gas using a T-piece connector or housing 30 having an insufflation gas inlet 31 and an outlet 32. The connector 30 also comprises an aerosol supply conduit 34 for delivering the aerosol from the aerosol generator 2 into a mixing chamber 33 in which the aerosol is entrained with insufflation gas. The aerosol insufflation gas mixture passes out of the connector 30 through the outlet 32 and is delivered along the insufflation gas conduit 15 to the trocar 6 for delivery into a body cavity 5. The connector 30 causes a substantial sudden reduction in the velocity of the insufflation gas from the insufflation gas inlet as it enters the mixing chamber 33. The connector 30 also causes a gradual increase in the velocity of the insufflation gas with entrained aerosol between the mixing chamber 33 and the outlet 32.

Methods of making composite prosthetic devices having improved bond strength

A method of making a composite prosthetic device, such as a hernia repair device, includes providing a support layer, juxtaposing a layer of an absorbable material with the support layer, and disposing an absorbable adhesive between the support layer and the layer of an absorbable material. The method includes heating the layers for melting the absorbable adhesive so as to bond the support layer with the layer of the absorbable material. Before the heating step, the moisture content of at least one of the layers is increased for improving thermal conductivity between the layers so as to enhance the strength of the bonds formed between the layers. The moisture content may be increased by exposing at least one of the layers to an environment having elevated relative humidity. In one embodiment, the support layer is polypropylene mesh, the layer of the absorbable material is oxidized regenerated cellulose, and the absorbable adhesive is polydioxanone.
