Abstract: The present invention is concerned with a method of manufacturing a tissue-integration device, and a tissue-integration device so produced, the method comprising the steps of wrapping a porous sheet of material around a mandrel in order to create overlapping layers of the porous sheet material, the wrapped mandrel then being placed in a mould in order to apply pressure and heat to the overlapping layers in order to effect the lamination thereof such as to form a device having spaces defined by overlapping pores of the adjacent layers.

Abstract: A gastric constriction device comprises a sheet extending over part of the wall of the stomach. Five bands extend around the stomach to fix the sheet in position relative to the stomach. The lower two bands extend from the first side of the sheet around the stomach only partially towards the second side. These lower two bands are not fixed to the second side. This arrangement results in an unconstricted portion of the stomach. In this manner, the device restricts expansion of the majority of the stomach wall while facilitating expansion of this unconstricted portion. The unconstricted portion is therefore free to expand or bulge outwardly upon ingestion. This expansion may trigger the feeling of satiation due to the presence of the vagal nerves in this portion of the stomach.

Abstract: Described herein are tissue repair implants comprising at least a first layer of peritoneal membrane. The first layer of peritoneal membrane can be located adjacent to a second layer of peritoneal membrane and can be in direct contact with the second layer of peritoneal membrane. Additional layers (e.g., a third or fourth layer) can be included. Where more than one layer is present, the layers can be affixed to one another. For example, a first layer of peritoneal membrane can be attached to the second layer of peritoneal membrane by an adhesive bond, suture, or staple. One or more of the peritoneal membranes can be non-crosslinked, partially crosslinked, or substantially fully crosslinked. Any of the layers of peritoneal membrane may be attached to a wall (e.g., an interior or exterior wall) of an abdominal tissue by an adhesive, suture, and/or staples.

Abstract: A tissue scaffold includes a first film having a plurality of cell openings and a second film adjacent the first film and having a plurality of cell openings larger than the cell openings of the first film. The cell openings of the first film interconnect with the cell openings of the second film to define pathways extending through the first and second films.

Abstract: A soft tissue implant comprises a condensed surgical mesh having a plurality of monofilament biocompatible fibers 12. Condensing of the fibers reduces the void space between adjacent fibers 12 in the mesh and reduces the surface area of the fibers 12 available for contact with tissue. Condensation of the fibers 12 may be achieved by applying mechanical pressure, and/or vacuum, and/or heat to the mesh.

Abstract: The present invention features soft tissue implants and methods for making same. The implants can includes a biocompatible film that is rendered porous due to the inclusion of uniformly or non-uniformly patterned cells, and the film has a thickness of less than about 0.015 inches in the event the starting material is non-porous and less than about 0.035 inches in the event the starting material is a microporous film. Multi-film implants can also be made.

Abstract: The present invention features soft tissue implants comprising major and minor struts and methods for making same. The implants can includes a biocompatible film that is rendered porous due to the inclusion of uniformly or non-uniformly patterned cells, and the film has a thickness of less than about 0.015 inches in the event the starting material is non-porous and less than about 0.035 inches in the event the starting material is a microporous film.

Abstract: A medical assembly comprises a soft tissue implant (16) for treating a first portion of body tissue during hernia repair, and a device (20). The device (20) comprises a support element (31) to support the soft tissue implant (16) during deployment. The device (20) comprises an elongate drawstring to releasably couple the soft tissue implant (16) to the support element (31). The support element (31) and the soft tissue implant (16) are movable between a collapsed delivery configuration, and an expanded deployment configuration. During deployment a second end (33) of the support element (31) engages with a second portion of body tissue to maintain the second portion of body tissue spaced-apart from the soft tissue implant (16). The support element (31) comprises an access opening (34) through which one or more instruments may be extended to access the soft tissue implant (16). The soft tissue implant (16) is attached to the first portion of body tissue using a suture.

Abstract: A soft tissue implant comprises a condensed surgical mesh having a plurality of monofilament biocompatible fibres 12. Condensing of the fibres reduces the void space between adjacent fibres 12 in the mesh and reduces the surface area of the fibres 12 available for contact with tissue 18. Condensation of the fibres 12 may be achieved by applying mechanical pressure, and/or vacuum, and/or heat to the mesh.

Abstract: A gastric constriction device (160) comprises a sheet (131) extending over part of the wall of the stomach (24). Five bands (151) extend around the stomach (24) to fix the sheet (131) in position relative to the stomach (24). The lower two bands (151) extend from the first side (152) of the sheet (131) around the stomach (24) only partially towards the second side (153). These lower two bands (151) are not fixed to the second side (153). This arrangement results in an unconstricted portion of the stomach (161). In this manner, the device (160) restricts expansion of the majority of the stomach wall while facilitating expansion of this unconstricted portion (161). The unconstricted portion (161) is therefore free to expand or bulge outwardly upon ingestion. This expansion may trigger the feeling of satiation due to the presence of the vagal nerves in this portion (161) of the stomach (24).
