摘要： An embolic coil deployment system for placing a coil at a preselected site within a vessel of the human body is provided. The deployment system includes a heating element at the distal end of a detachment member and a heat-responsive coupling attached to a delivery member for holding the coil during positioning of the coil. The heating element is heated to reduce the strength of and sever the heat-responsive coupling for releasing the coil at a desired position within the body vessel.

摘要： An ultrasonic imaging catheter comprises a flexible catheter body having a rigid housing at its distal end. A tapered flexible end piece is secured to the distal end of the rigid housing, and a flexible guide wire tube extends in parallel to both the housing and the flexible end piece from the catheter body. The guide wire tube defines a guide wire lumen capable of receiving a movable guide wire, and the combined structure of the housing, flexible end piece, and flexible guide wire tube minimize constriction of the guide wire as it passes through the guide wire lumen.

摘要： In a shapable catheter and method for positioning a shapable catheter within a body cavity, a core wire is provided which includes a pre-shaped region bent into a predetermined shape. A catheter is provided which includes a lumen proportioned to slidably receive the core wire. The catheter includes a rigid proximal section and a flexible distal section. During use, the distal end of the catheter is inserted through a patient's vasculature and is passed into a body cavity. The pre-shaped region of the core wire is passed into the lumen and is straightened by the rigid proximal section of the catheter. The pre-shaped region is passed further into the catheter until it reaches the flexible distal region, in which the pre-shaped section re-assumes its predetermined shape and causes the core wire to form the distal section of the catheter into the predetermined shape. The distal section of the catheter is positioned in contact with tissue in the body cavity, and electrodes carried by the distal end are used to map and/or ablate the tissue.

摘要： A guidewire imaging catheter includes a catheter body, housing secured to the distal end of the catheter body, a drive cable extending through a central lumen of the catheter body, and an imaging system disposed within the housing and coupled to the drive cable. A fixed guidewire is secured to the distal tip of the housing, and the catheter body is highly flexible while retaining sufficient torsional stiffness to allow the entire catheter to be used as a guidewire. Thus, the imaging guidewire can be used to first image a desired region within a patient's vascular system and subsequently as a guidewire to allow placement of a desired interventional catheter.

摘要： An ultra-thin distal sheath section of the sheathed system uses heat shrinkable elastomer tubing with a wall thickness that is less than 0.05 mm and may be less than 0.025 mm. There are two methods for securing the ultra-thin distal sheath section over the distal tip. A first method is to employ another thin tube shrunk down over the distal end of the ultra-thin distal sheath. It is also envisioned that simply shrinking the ultra-thin distal sheath section down on the tapered section of the distal tip will hold it securely. A monorail (rapid exchange) version of this stent delivery system is also envisioned. A second version uses radioopaque elastic bands mounted over the ends of the balloon just proximal and just distal to the stent to provide a low profile for a primary stent delivery system. These radioopaque elastic bands could contain a high-density material such as tungsten to make them radioopaque and eliminate the need for radioopaque markers normally attached to the angioplasty balloon inner shaft.
摘要翻译：护套系统的超薄远端护套部分使用壁厚小于0.05mm且可能小于0.025mm的热收缩弹性体管。有两种方法用于将超薄远端鞘部分固定在远端上。第一种方法是使用在超薄远侧鞘的远端下方收缩的另一条细管。还可以想到，将超薄远端鞘部分简单地收缩在远侧尖端的锥形部分上将牢固地保持。还设想了该支架输送系统的单轨（快速交换）版本。第二个版本使用放射性弹性带，其安装在球囊的端部的刚好在支架的近侧并且仅在支架的远端处，以为主支架输送系统提供低轮廓。这些不透射线的弹性带可以含有诸如钨的高密度材料，使其不透射线，并且不需要通常附着于血管成形术球囊内轴的不透射线标记。
