摘要： A system for delivering an implant within a patient is disclosed. The activation of the heater coil causes the degradation, melting or reduction of a component that brings the heater coil into or out of electrical contact with another component, or causes the individual loops of the coil to contact each other, thereby resulting a notable change in resistance in the circuit supplying the heater coil with electricity. A core wire terminates prior to the distal end of the device, allowing for greater flexibility.

摘要： "métodos para o tratamento de uma doença, deformação ou distúrbio de um paciente humano ou veterinário, e para a preparação de um polímero de hidrogel ambientalmente sensível, e, hidrogel". hidrogéis que se expandem volumetricamente em resposta a uma mudança em seu ambiente (por exemplo, uma mudança no ph ou temperatura) e seus métodos de fabricação e uso. geralmente, os hidrogéis são preparados pela formação de uma mistura de reação líquida que contém a) monômero(s) e/ou polímero(s), pelo menos parte(s) dos quais são sensíveis a mudanças ambientais (por exemplo, mudanças no ph ou temperatura ambiente), b) um reticulador e c) um iniciador da polimerização. se desejável, um porosigênio pode ser incorporado na mistura de reação líquida para criar poros. após o hidrogel ser formado, o porosigênio é removido para criar poros no hidrogel. o hidrogel pode também ser tratado para fazer com que ele assuma um volume não expandido em que permanece até que uma mudança em seu ambiente faça com que ele se expanda. estes hidrogéis podem ser preparados em muitas formas incluindo grânulos, filamentos e partículas. usos biomédicos destes hidrogéis incluem aplicações em que o hidrogel é implantado no corpo de um paciente e uma condição ambiental no sítio de implantação faz com que o hidrogel se expanda in situ.

摘要： One embodiment of the present invention discloses a balloon catheter employing a reinforced, co-axial, duel lumen design, that is operable to use with large gauge guidewires. In certain embodiments, at least one of the lumens is formed of a multilayer, tubular element in which one of the layers functions, in part, to provide radial reinforcement to the tubular element.

摘要： In one embodiment, the present invention relates to a mechanically releasable delivery system. More specifically, this embodiment includes an implantable device secured by tether at a distal end of the delivery system. The tether is fixed to the implantable device and looped around a selectively slidable mandrel. When the mandrel is retracted to expose its distal end, the looped tether slides off the mandrel, freeing the implantable device. Alternately, the tether can be fixed to the delivery system, wrapped around a portion of the implantable device and looped on to the slidable mandrel. Preferably, movement of the mandrel is controlled by an actuation control on the handle of the delivery system, allowing the user to selectively release the implantable device during a medical procedure.

摘要： A system and method for quickly detaching an implant and for locating the detachment zone of a detachable implant. A sensor determines a sudden change in the local environment as the sensor passes from within a microcatheter to being exposed to the vasculature. The sensor may be a temperature sensor, ultrasonic sensor, pressure sensor or the like. If the detachable implant assembly uses a heater coil to detach the implant, the heater coil may be used as a sensor. Additionally, the implant itself may be used as a sensor if a change in electrical resistance is detectable as the implant exits the microcatheter and changes shape.
