摘要： The disclosure pertains to a medical device deployment system comprising a restraint member which holds the embolic protection filter in a restrained, or partially collapsed, state for insertion into a lumen and transit to a desired deployment site. The restraint member comprises two or more portions which differ in their mechanical ability to resist the radial forces exerted by various portions of the medical device when it is in a restrained, or partially collapsed, state. The restraint member is maintained in a restraint configuration by an actuation member which engages portions of the restraint member lying on opposite sides of a generally axial gap until deployment of the medical device is desired. Withdrawal of the actuation member allows the restraint member to release the medical device which may then return to a deployed state. The invention also provides a method for assembling a medical device deployment system.

摘要： Systems and methods for transporting and deploying intravascular devices through a body lumen are disclosed. An intracorporeal device in accordance with an exemplary embodiment of the present invention can include an elongate member with a proximal portion defining first, second and third lumens and a distal portion defining a containment lumen. A filter assembly can be disposed within the containment lumen, with a filter wire attached to the filter assembly and extending through the first lumen. A guidewire can be passed through a distal guidewire lumen that extends through the filter assembly. The guidewire can extend through the distal guidewire lumen and through the second or third lumen. With the filter assembly disposed in the elongate member, the guidewire can then be advanced through a patient's vasculature, the filter delivery system advanced through the vasculature over the guidewire and the filter assembly deployed from the containment lumen.

摘要： An improved catheter system having an ultrasonic imaging transducer coupled to a drive cable disposed within a lumen of a flexible tubular catheter body. An improvement including a reconfiguration of the ferrites in the hub assembly, such that the need for the gap between the ferrites is removed. A strain relief member is provided to increase the strength of the electrical transmission lines to enable them to withstand the tensile forces caused by either flushing and/or pull-back operations. A device which allows the electrical transmission lines to extend their length when placed in tension may also be employed to provide strain relief to the electrical transmission lines. Another improvement includes a counter-wound coil structure, which may either expand or contract as the drive cable is being rotated to strengthen the drive cable. The distal tip of the catheter body may be redesigned to provide a lumen which allows for the release of flushing fluids through a distal port in the guidewire lumen.
