摘要:
A urinary catheter having an insertable shaft formed from a blend of an ethylene and/or propylene based polymer and water swellable material. The catheter having a hydrophilic coating disposed on the outer surface of the insertable catheter shaft.
摘要:
Compositions and methods for glass composites suitable for tissue augmentation, biomedical, and cosmetic applications are provided. The glass microsphere component of the composites are biologically inert, non-reactive and act as a nearly permanent tissue filler. One embodiment provides a tissue augmentation composite containing an effective amount of solid glass microspheres, hollow glass microspheres, porous wall hollow glass microspheres, or combinations thereof with a suitable biocompatible matrix to serve as a bulking agent when injected into a patient. The compositions can be used for soft or hard tissue augmentation as well as delivery of cargos on demand.
摘要:
A regenerative respiratory tract prosthesis comprising a tubular extracellular matrix (ECM) member having a lumen therethrough, at least first and second biodegradable polymeric anchors disposed on the tubular member exterior surface. The first and second anchors can include a microneedle tissue engagement member.
摘要:
The invention relates to tubular prostheses or implants having increased protein adsorption on the external surface and not on the internal surface, and to the process of obtaining such prosthesis by specific surface treatments on localized parts of said prosthesis.
摘要:
The invention describes a tubular patch (3) made of PGA fabric, optionally containing within it a mesh tubular support (10) in PGA/ PLA, for implantation to replace one or more urethral and/or ureteral removed segments for use in tissue reconstruction of said removed segments for the treatment of diseases such as necrosis, stenosis, tumours, trauma, iatrogenic injuries and the like, or congenital malformations, wherein the patch is suitable to be used without any coating of culture cells previously cultured and/or surface treatment to promote engraftment during regrowth of the autologous tissues.
摘要:
Biodegradable implants including an ECM material and methods for treating a pelvic floor condition are described. ECM particles can be present within or on the surface of a pelvic implant, such as a biodegradable mesh, a pouch, or a urethral stent. After implantation the implant can provide tissue support, degrade over a period of time, and deposit the ECM material in the implantation area for regeneration of tissue and long term benefit.
摘要:
A biocompatible textile and methods for its use and fabrication are disclosed. The textile may be fabricated from electrospun fibers forming windings on a mandrel, in which the windings form openings having a mesh size between adjacent windings. The textile may also be fabricated by the addition of solvent-soluble particles incorporated into the textile while the windings are formed. Such particles may be removed by exposing the textile to a solvent, thereby dissolving them. Disclosed are also replacements for animal organs composed of material including at least one layer of an electrospun fiber textile having a mesh size. Such replacements for animal organs may include biocompatible textiles treated with a surface treatment process.
摘要:
A description is given of a patch (1) for the replacement of a portion of bladder wall, following partial cystectomy, comprising a textile (2) deriving from a PGA yarn and provided with a star-shaped support frame, flexible and harmonic, formed by a plurality of radial strips (3) manufactured by injection of a PGA/PLA copolymer, said patch (1) being suitable for making autologous fibrous capsule cells, generated by the process of tissue reconstruction, grow thereon after its insertion inside the patient.
摘要:
A description is given of a domed cap (100) for the enlargement of an atrophied bladder (200), in biocompatible and absorbable material comprising a textile (1) made with yarns or with monofilaments deriving from PGA fibres, characterised in that said textile (1) is supported by a star-shaped frame with domed profile, formed by a plurality of radial strips (3) manufactured by injection of a PGA/PLA copolymer, said cap (100) being suitable for growing thereon autologous fibrous capsule cells, generated by the process of tissue reconstruction, after its insertion inside the patient.
