摘要:
A mesh fiber member having a plurality of biodegradable fibers, the mesh fiber member being configured to induce modulated healing of damaged biological tissue when deployed proximate thereto. The strands comprise an extracellular matrix (ECM) composition or an ECM-mimicking biomaterial composition, such as poly(glycerol sebacate) (PGS), and can include a biodegradable ECM, polymeric or ECM-mimicking biomaterial composition coating.

Implantable prostheses for reinforcing and repairing defects in a muscular or tissue wall and a method for fabricating the prostheses that minimizes wasted mesh material and reduces the labor and time required for fabrication. The prosthesis may include a plug body formed of surgical mesh material having a closed end, a larger open end, and a cavity extending therebetween, and a filler body formed of the surgical mesh material comprising a plurality of petals extending radially outwardly from and spaced laterally about a common base disposed in the plug body with the common base attached to the closed end of the plug body. The plug bodies are cut as circular pieces, and the filler bodies are cut as hour-glass shaped pieces from the same sheet of material so as to leave virtually no wasted mesh material. The filler pieces may be attached to the plug body piece by welding.
摘要:
A reinforcement device for reinforcing tissues having one or more structural deficiencies includes a longitudinally-extending reinforcing layer for treating the structural deficiency, a plurality of spiked naps distributed across the reinforcing layer and projecting therefrom for adhering to the tissue, and a dissolvable matrix layer covering at least a portion of the reinforcing layer and a portion of the plurality of spiked naps. The matrix layer increases the time before the spiked naps substantially adhere to the tissue, thereby allowing the practitioner additional time to position the reinforcement device.

The implantable reinforcement prosthesis, in particular for reinforcing the abdominal wall, comprises a reinforcement part (10) forming a netting intended to be incorporated into the inner surface of the wall (1) in order to reinforce said wall and a plurality of flat strips (20; 120) made from textile material extending from the edges of the reinforcement part and intended to be placed in transfixing penetration in the wall to each side of the area to be reinforced. According to a particular provision, the strips (20; 120) comprise anchoring wires (30; 130) intcorporated by interleaving into said strips, and extending along the length of said strips. The strips can be formed from two different segments of strips, depending on the region of the wall in which they are to be positioned.
摘要:
This disclosure describes a membrane configured to guide bone and tissue regeneration for a bone defect. The membrane may comprise a first layer, a second layer, one or more perforations, a binder, and/or other components. The first layer of the membrane may be configured to contact bone. The first layer may include pores configured to promote ingrowth of bone regenerating cells into the first layer. In some implementations, the first layer may be a continuous sheet of microporous material without large perforations. The second layer may be configured to substantially prevent fibrous connective tissue from growing into the bone defect. The second layer may comprise a relatively dense structure. The second layer may be fixedly coupled to the first layer. In some implementations, the perforations may comprise co-axial through-holes having common dimensions through the first layer and the second layer. The perforations may be configured to enhance ossification.
摘要:
A three-dimensional fabric structure in a form of a pocket for use in a breast reconstruction surgical procedure such as single-stage or two-stage breast reconstruction. The silk scaffold employs a knit pattern that substantially prevents unraveling and preserves the stability of the mesh or scaffold device, especially when the mesh or scaffold device is cut. An example scaffold device employs a knitted mesh including at least two yarns laid in a knit direction and engaging each other to define a plurality of nodes.
摘要:
An auto-graft bio-synthetic mesh and a method of application for wound closure is described. The mesh is utilized for wound closure wherein an abdominal incision is effected through the peritoneum and the rectus abdominal sheath of the rectus muscle such as when repairing ventral or paracoslostomy hernias. The mesh comprises a flexible patch of woven fibers and wherein the patch is one of a substantially circular patch or a patch having a substantially circular delineation thereon whereby to provide guidance for the formation of stitches in at least one circle to secure the patch to the peritoneal peritoneum and the rectus abdominal sheath of the rectus muscle. The patch is secured by applying stitches all about an outer circular edge of the patch and an inner circle thereof. A suture clip for joining portions of bodily soft tissue is also described.
摘要:
Implants for the treatment of pelvic support conditions and methods of implementing the same. The implants comprise relatively soft, flexible bodies and relatively strong arms extending in predetermined orientation therefrom. Methods and devices for placing the implants minimize trauma to the pelvic floor and provide well-anchored support to pelvic organs without interfering with sexual or other bodily functions.
摘要:
An implant or sling device is provided with a tension adjustment system. The adjustment system can include one or more small pressure bulbs placed against the inferior pubic rami for support. By palpating the bulbs (one on left and one on right), the pressure can be adjusted to control the tension of the implant. Other conduits, balloons, introduction tools, ports and fluid adjustment components and mechanisms can be included to provide selective adjustment of the tension of the implant relative to the supported tissue or organ.
摘要:
According to one aspect of the invention, composite implants for soft tissue repair are provided which comprise (a) a substantially two-dimensional piece of biologic matrix material and (b) one or more non-absorbable synthetic polymeric filaments.
