Systems and devices for endovascular treatment of intracranial aneurysms are described. Various configurations of coiled implants may be used as stenting devices or aneurysm coils. The implants include one or more filaments wound about a longitudinal axis to form a generally tubular shape. Lateral flexibility of the implants may be manipulated by, for example, adjusting a pitch between adjacent filaments, using different materials for the filaments, employing different filament cross-sectional shapes, grouping filaments into pluralities of varying flexibilities, and nesting inner coils within outer coils.

Aneurysm treatment coils

This invention is directed to implantable coils and, more particularly, to a coil implant having a stretch-resistant member internal to the coil. The implant of the invention is able to freely articulate and torque prior to delivery. Once delivered, the implant is no longer stretch resistant and is therefore able to substantially conform to the vascular site.

Implant including a coil and a stretch-resistant member

An intravascular implant delivery system carries an implant by retaining an engagement member engaging the implant in a position proximal of an aperture at a distal end of the delivery system. The engagement member is retained proximal to the aperture by a cord that obstructs the movement of the engagement member through the aperture. The engagement member is free to rotate and move within an area defined by the delivery system, allowing the implant to react to forces imparted to the implant by the movement of the delivery system and implant through a delivery catheter. Once the implant is in a desired implant position, the cord is moved away from an aperture and the engagement member is allowed to move away from the delivery system.

System and method for mechanically positioning intravascular implants

This invention is directed to an implant having a coil for embolizing a vascular site, such as aneurysm. The coil has a specific three-dimensional shape that is achieved by winding the coil around a mandrel in a specific pattern and then heat setting the coil and the mandrel, another aspect of the invention. The three-dimensional shape resembles unclosed mobius loops. Also provided are methods of making the coil and methods of embolizing vascular site.

A guidewire extender particularly suited for use in percutaneous transluminal coronary angioplasty. A tubular connector member attaches to the proximal end of a steerable guidewire. A helical coil bonded to a male insertion segment of a proximal extension member contacts an inward depression on the tubular connector. The extension member mates with the tubular connector to extend the guidewire by rotating the extension member to advance the helical coil past the depression. Some axial play between the coupled components is possible. The extension member locks to the guidewire without special tools. Manufacture and assembly are simplified.
