摘要： A controller circuit for activating and deactivating an electrical power converter that provides power to a device includes power input terminals on a primary side, and power output terminals on a secondary side, which are configured to provide power to the device. The controller circuit includes a detection circuit configured to determine whether the device is connected and, if connected, causes power to be routed to the electrical power converter to activate the electrical power converter. When the device is not detected, the electrical power converter is deactivated until the device is reconnected.

摘要： A circuit protection device includes a substrate with first and second electrodes connected to the circuit to be protected. The circuit protection device also includes a heater element between the first and second electrodes. A sliding contact is connected by a sensing element to the first electrode, second electrode, and heater element, thereby bridging and providing a conductive path between each. A spring element is held in tension by, and exerts a force parallel to a length of the substrate against, the sliding contact. A flux material is provided around the sensing element. Upon detection of an activation condition, the sensing element releases the sliding contact and the force exerted by the spring element moves the sliding contact to another location on the substrate at which the sliding contact no longer provides a conductive path between the first electrode, second electrode, and heater element. The flux allows the sliding contact to move without dragging the sensing material.

摘要： A reflowable thermal fuse includes a conduction element with first and second ends, disposed within a housing. The reflowable thermal fuse also includes an elastic element disposed within the housing and adapted to apply force on the conduction element in an activated state of the reflowable thermal fuse. A restraining element is utilized to secure the elastic element and prevent the elastic element from applying force on the conduction element in an installation state of the reflowable thermal fuse. Application of an activating current through the restraining element causes the restraining element to break and thereby release the elastic element and place the reflowable thermal fuse in the activated state.

摘要： Balloons for medical devices, particularly balloon angioplasty catheters, are made from particular block copolymer thermoplastic elastomers in which the block copolymer is made up of hard segments of a polyester or polyamide and soft segments of polyether; the polyester hard segments are polyesters of an aromatic dicarboxylic acid and a C2-C4 diol; the polyamide hard segments are polyamides of C6 or higher carboxylic acids and C6 or higher organic diamines or of C6 or higher aliphatic ω-amino-α-acids, and the polyether soft segments are polyethers of C2-C10, diols; the block copolymer has a low flexural modulus, namely less than 150,000 psi; the block copolymer has a hardness, Shore D scale, of greater than 60; and the percentage by weight of the block polymer attributable to the hard segments is between about 50% and about 95%. The polymers provide high strength, thin wall, compliant and semi-compliant balloons, which leads to a low profile catheter. The low profile catheters have very good initial crossing, good trackability, good recrossing after first inflation.

摘要： A processing technique and a composition which allow compositions of PBT polymers or copolymers to be formed into blow molded articles, especially medical balloons such as dilatation or stent placement balloons, from extruded tubular parisons. The process includes a longitudinal stretch step run at a temperature below the Tg of the polymeric material and a radial expansion step run at a temperature above the Tg of the polymeric material. During the longitudinal stretch step, the tubing is subjected to high internal pressure. In the composition a small amount of boric acid is added to the polybutylene terephthalate in a melt blend to give a formulation which has reduced crystallinity after extrusion and which can more readily fashioned into high strength blow molded articles than PBT by itself. Articles, which may be formed using the invention include medical device balloon articles in which the polymer consists essentially of PBT optionally blended with boric acid.
