摘要： This is a composite guidewire for use with a catheter for accessing a targeted site in a lumen system of a patient's body. The guidewire core or guidewire section may be of a stainless steel or a high elasticity metal alloy, preferably a Ni—Ti alloy, also preferably having specified physical parameters. The composite guidewire assembly is especially useful for accessing peripheral or soft tissue targets. The invention includes multi-section guidewire assemblies having super-elastic alloy or stainless steel ribbon braided reinforcements along a least a portion of the core. A variation of the inventive guidewire includes a braid and a tie layer (and one or more lubricious polymers on the tie layer exterior) to enhance the guidewire's suitability for use within catheters and within the interior of vascular lumen.

摘要： This is a composite guidewire for use in a catheter and is used for accessing a targeted site in a lumen system of a patient's body. The guidewire core or guidewire section may be of a stainless steel or a high elasticity metal alloy, preferably a Ni--Ti alloy, also preferably having specified physical parameters. The composite guidewire assembly is especially useful for accessing peripheral or soft tissue targets. Variations include multi-section guidewire assemblies having (at least) super-elastic distal portions and super-elastic braided reinforcements along the mid or distal sections. A variation of the inventive guidewire includes the coating of the wire with a tie layer and then with a one or more lubricious polymers to enhance its suitability for use within catheters and with the interior of vascular lumen.

摘要： This is a catheter assembly and a section of that catheter assembly. That catheter assembly may be used in accessing a tissue target within the body, typically a target which is accessible through the vascular system. Central to the invention is the use of a braided metallic reinforcing member, typically of super-elastic alloy ribbon, situated within the catheter body in such a way to create a catheter having an exceptionally thin wall, controlled stiffness, high resistance to kinking, and complete recovery in vivo from kinking situations. The braid may have a single pitch or may vary in pitch along the axis of the catheter or catheter section. The braided ribbon reinforcing member typically is placed between a flexible outer tubing member and an inner tubing member to produce a catheter section which is very flexible but highly kink resistant. The catheter sections made according to this invention may be used alone or in conjunction with other catheter sections either made using the concepts shown herein or made in other ways. The more proximal sections of the catheter assembly are often substantially stiffer than the more distal sections due to the presence of stiff polymeric tubing or metallic tubing or composited materials in the stiffer section.

摘要： This invention is an apparatus for the formation of occlusions in spaces in the human body, occluding such as thrombi in arteries, veins, aneurysms, vascular malformations and arteriovenous fistulas. In particular, it deals with a one piece assembly having an improved electrolytically erodable link to an occlusive member and further having an incorporated return electrode in the assembly. The occlusion-forming member is introduced to and is intended to remain at the desired occlusion site. The invention also relates to the joint itself. The invention further includes a method for introduction and electrolytic separation of the device.

摘要： This is a surgical device usually delivered through an intravascular catheter. It is designed to pierce and remove emboli often found in tortuous vasculature. The device includes several sections. The device has a core element. Placed around the distal end of the core wire is a collapsible but self expanding embolism collection assembly. That collector assembly is typically joined to the core wire at its distal end. The collector assembly may have a generally conical distal portion when expanded and may have a proximal section having varied purposes, e.g. for centering the collector assembly in the vascular lumen. The assembly further may have an actuator which permits the collector assembly to expand after deployment.

摘要： This is a catheter having a shaft, the layers of which are coextruded in an intermittently changing pattern that produces particular mechanical and frictional properties in the structure. The outer layer of the catheter shaft is comprised of a material which has greater flexibility than the material which comprises the inner layer of the catheter shaft. The stiffer material which comprises the inner layer has frictional properties which facilitate guidewire passage and control. The invention includes the substituent shaft per se and a method of making the shaft.

摘要： This is an implant for placement in the human body and an assembly for so placing that implant. Most desirably, it is an implant for use in the vasculature of the human body and is used to occlude some space in that vasculature as a portion of a treatment regimen. The implant itself is preferably a component of a deployment device using an electrolytically severable joint. The implant is electrically isolated from the electrolytically severable joint by a highly resistive or insulative layer. Such isolation and minimization of the conductive pathway from the placement apparatus to the body's fluids appears to enhance the susceptibility of the electrolytic joint to quick erosion and detachment of the implant from the deployment media. Although the implant itself is preferably a vaso-occlusive device, it may instead be a stent, a vena cava filter, or other implant which may be installed in this manner.

摘要： A pusher-vasoocclusive coil assembly that is advanced through a catheter to a site within a vessel and is manipulated to detach the coil from the assembly. The coil has an enlarged member at its proximal end and the pusher has a keyway at its distal end that receives the enlarged member in interlocking engagement. The pusher and coil are coupled by placing the enlarged member in the keyway and enclosing the coupled assembly with a coaxial sleeve. The coil-pusher-sleeve assembly is positioned at the site and the sleeve is retracted to allow the member to move out of the keyway to uncouple the pusher and coil.
