Es wird vorgeschlagen, dass das Mittelgewirke (2a) die Mehrzahl von Fäden (5a, 5b, 5c) umfasst.
摘要:
An endoluminal prosthesis (20) comprises a first membrane (25) having a lumen (29) for allowing fluid flow, and a stent (38-68) having contracted and expanded states. At least one surface enhancement member (27, 28), separate from the stent, is secured to the stent prior to a coaxial overlapping state of the stent and the first membrane. The at least one surface enhancement member has stronger bonding properties with the first membrane, relative to bonding properties of bare surfaces of the stent with the first membrane, when the stent and the first membrane are in the coaxially overlapping state.
摘要:
A residual limb suspension liner (10) for a prosthesis has a first layer (14) defined by a first elastomeric material and forms a continuous circumferential internal surface (22) of the liner. The liner also includes a second layer (16) defined by a second elastomeric material different from the first elastomeric material. The second layer (16) has a first surface adjacent to and integrally joined to the first layer (14). The second layer (16) has a variable radial thickness over an anterior aspect of the liner.

A method of making an endoluminal stent-graft, comprises the steps of: placing a first covering member composed of a boicompatible polymer on a surface; placing a radially expandable stent over said first covering member; laying down a layer of an activatable adhesive material over the first covering member and the stent; placing a second covering member composed of a biocompatible polymer over the stent; and applying pressure.

A prosthetic implant for forming a support structure between adjoining vertebrae in a spinal column. The prosthetic implant includes a generally spherical or ellipsoidal body that at least partially engages a surface of adjacent vertebrae.
摘要:
In a method and system for producing an implant, the latter is designed with one or more surfaces extending in the longitudinal direction of the implant. Two or three production stages can be used. In one stage, either a topography with a long wave pattern is produced by means of cutting work, or laser bombardment or further cutting work is used to produce a topography with an intermediate-length wave pattern. In addition, an oxidation process or shot-peening or etching is used to produce an outer layer. When using two of said production stages, said cutting work or said laser bombardment or further cutting work is followed by the oxidation process or the shot-peening or etching method. When using all three production stages, cutting work is followed by laser bombardment, or further cutting work, which in turn is followed for example by the oxidation process. The invention also relates to an implant which is produced using the method and is identified, ordered and produced using the system. The invention permits effective treatment of different implant situations.
摘要:
A composite bone graft (1) for implantation in a patient, to methods of making, and using the composite bone graft along with methods for treating patients by implanting the composite bone graft at a site in a patient. The composite bone graft includes two or more connected, discrete, bone portions (2-4), and includes one or more bio-compatible connectors (7) which hold together the discrete bone portions (2-4) to form the composite bone graft (1). The composite bone graft (1) may include one or more textured bone surfaces (14b). The textured surface (14a, 14b) preferably includes a plurality of closely spaced protrusions, preferably closely spaced continuous protrusions. The composite bone graft (1) is useful for repairing bone defects caused by congenital anomaly, disease, or trauma in a patient, for example, for restoring vertical support of the anterior, and/or posterior column. Implantation of the composite bone graft results in improved graft stability, and osteo-induction ability, without a decrease in mechanical strength.
