摘要:
A system for treating a vascular condition includes a stent including hydroxyapatite fibers interwoven to define a stent lumen. Another aspect of the invention is a method of manufacturing a stent by forming hydroxyapatite fibers and biodegradable polymeric fibers, and interweaving the fibers to form a stent wall. The hydroxyapatite fibers can be formed by a sol-gel process, followed by spinning of the gel to form the hydroxyapatite fibers.

An implantable interference screw for use in a soft tissue repair, the screw having a bioresorbable body comprising a plurality of interconnected pores, the body having an instrument interface in one end and a thread around an exterior of the body starting from distal end. The plurality of interconnected pores of the resorbable body are substantially filled with a bioresorbable polymer.

An intravascular filter (10) has a main filter portion (12) and an anchor portion (14). The main filter portion is made up of a number of struts (16), which form a first and a second biodegradable filter sections (26,28). The first and the second biodegradable filter sections biodegrade at different rates. The anchor portion secures the filter within a blood vessel and also has a collar (32). The first and the second biodegradable portions may have a different thickness and may be comprised of different materials. The collar may be formed from a resiliently deformable material.
摘要:
An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon.In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.
摘要:
The present invention relates to a biocorrodable implant in which corrosion may be triggered or accelerated after implantation by applying an external stimulus, the implant having a base body which is completely or partially composed of a biocorrodable metallic material, and the base body having a coating with a protective layer which is not biocorrodable. According to the invention, the implant has control elements which are configured in such a way that the protective layer, optionally in combination with the control elements, completely or partially encloses the base body so as to be impermeable to bodily medium, and the protective layer being convertible to a form which is permeable to bodily medium as the result of a change in shape of the control elements which may be regulated and/or controlled by an external stimulus.
摘要:
A composite fixation device is described herein which includes a first and second biodegradable material. The first and second biodegradable materials degrade at different rates thereby permitting tissue ingrowth into the device prior to degradation of the entire device.
摘要:
Methods of treating renal cancers and other kidney-related inflammatory disorders with a bioabsorbable polymer scaffold (such as a stent) are described. The treatments are provided as alternative to complete or partial surgical removal of a diseased kidney.
摘要:
An implant for deployment in select locations or select tissue for regeneration of tissue is disclosed. The implant includes collagen and or other bio-resorbable materials, where the implant may also be used for therapy delivery. Additionally, the implant may include, or have blended in, an additive, such as an osteoinductive factor, for example biocompatible ceramics and glass.
摘要:
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.
摘要:
Surgical implants are provided which include a film comprising a first therapeutic agent and a mesh comprising a second therapeutic agent. The surgical implant includes a film in direct contact with a mesh. The first therapeutic agent may be released at a first rate and the second therapeutic agent may be released at a second rate.
