Abstract:
A formulation for generating an adhesion barrier that includes a plurality of particles or a dry powder that is made of a polymer combination of at least one biodegradable polymer and at least one water soluble polymer is disclosed. Methods of making and delivering the formulation are further disclosed. The formulation of particles is deposited on a surface of internal body tissue and the deposited formulation absorbs moisture from the tissue and forms a film over the surface. The film acts as an adhesion barrier by reducing or preventing adhesion of the surface to other body tissue.
Abstract:
This invention discloses a method for determining the relationship of a Customer Edge Router (CE) with a Virtual Private Networking (VPN), which comprises: assigning in advance for each CE device at least one Route Target (RT) value to form the RT table of the CE, creating CE Route Communities (CERC) in the network management and assigning for each created CERC a Hub RT value and a Spoke RT value. The method further comprises: dividing the RT table of the current CE to be matched with a CERC into an import RT table and an export RT table according to the import/export attributes of the RT values, and determining whether the CE belongs to the designated CERC and whether the CE is a Hub CE or a Spoke CE in the CERC according to the RT values in the import RT table and export RT table obtained as well as the Hub RT value and Spoke RT value assigned to the designated CERC. With the method, the relationship between a CE and a CERC as well as the type of the CE in the CERC can be learned by a reverse deduction based on the RT tables known on the network so that VPN information can learn from the network management. Accordingly, less human effort is involved and cost of network maintenance greatly decreased.
Abstract:
An apparatus and method for supporting a plurality of components, at least one of which is a heat-generating electrical device such as a power semiconductor device, are disclosed. In some embodiments, the apparatus includes a first structure having a first surface on one side of the structure configured for interfacing a first of the plurality of components and a second surface on another side of the structure, and also includes a second structure capable of receiving the first structure, where one of the second surface and an additional surface of the second structure includes a tip that is in contact with the other of those surfaces. The apparatus further includes at least one component configured to assist in retaining the first and second structures relative to one another, where notwithstanding the at least one component the first structure is capable of pivoting relative to the second structure about the tip.
Abstract:
A mounting apparatus for mounting a drive bracket on which a protruding portion is provided, includes an enclosure, and a mounting member. The enclosure includes a base wall for supporting the drive bracket thereon, a side wall extending from one side of the base wall, and a holder extending from the side wall. The mounting member is movably attached to the holder. The mounting member includes a locking portion extending therefrom for engaging with the protruding portion of the drive bracket.
Abstract:
A medical device such as a stent with a catheter, delivery balloon and an infrared energy source is disclosed. The infrared energy source heats the delivery balloon, and/or the stent to a temperature above body temperature, thereby increasing the flexibility of the stent such that formation of cracks in the stent upon its expansion is reduced or eliminated. Either the delivery balloon, and/or the stent may include an infrared energy absorbing material.
Abstract:
This invention relates to a method of extending the shelf-life of constructs, in particular bioabsorbable stents, comprising semi-crystalline polymers by increasing the crystallinity of the polymers.
Abstract:
A heat exchanging device includes a receptacle having a chamber for receiving a fluid medium, a housing received within the receptacle and having an outer peripheral wall arranged to allow the fluid medium to flow into the housing via the upper portion of the outer peripheral wall, and having an inner peripheral wall having a lower portion directed toward the lower portion of the receptacle. A circulating device may circulate the fluid medium to flow from the upper portion of the housing and then toward the lower portion of the receptacle. A coil is arranged to have a fluid material to flow in a direction opposite to that of the fluid medium, to allow the fluid medium to transmit and to release heat to the fluid material.
Abstract:
Methods and systems for manufacturing an implantable medical device, such as a stent, from a tube with desirable mechanical properties, such as improved circumferential strength and rigidity, are described herein. Improved circumferential strength and rigidity may be obtained by inducing molecular orientation in materials for use in manufacturing an implantable medical device. Some embodiments may include inducing molecular orientation by expansion of a molten annular polymer film. Other embodiments may include inducing circumferential molecular orientation by inducing circumferential flow in a molten polymer. In certain embodiments, circumferential orientation may be induced by expansion of a polymer tube. Further embodiments may include manufacturing an implantable medical device from a biaxially oriented planar polymer film.

Abstract:
A device and a method of manufacturing an implantable medical device, such as a stent, are described herein. The device includes a metallic region composed of a bioerodable metal and a polymer region composed of a biodegradable polymer contacting the metallic region. The metallic region may erode at a different rate when exposed to bodily fluids than the polymer region when exposed to bodily fluids. In certain embodiments, the polymer region is an outer layer and the metallic region is an inner layer of the device. A further aspect of the invention includes device and a method of manufacturing the device that includes a mixture of a biodegradable polymer and bioerodable metallic particles. The mixture may be used to fabricate an implantable medical device or to coat an implantable medical device. In some embodiments, the metallic particles are metallic nanoparticles.
