Nov 4, 1996

Appl. No.:

8/743494

Assignee:

Target Therapeutics, Inc. - Fremont CA

International Classification:

A61B 1708

US Classification:

606151

Abstract:

A solderless sacrificial link between a detachable member which is placed at and is intended to remain at a desired site within the mammalian body and the core wire used to introduce the detachable member. The detachable member device may be one used to create emboli in the vascular system or may be of any other type deliverable into the human body and detached into an ionic aqueous environment, either for later removal or permanent placement.

Appl. No.:

9/389914

Inventors:

Michael J. Mariant - San Jose CA

Assignee:

Target Therapeutics, Inc. - Fremont CA

International Classification:

A61B 1732

US Classification:

606191

Abstract:

This is an implantable vaso-occlusive device. It is a complex, helically wound coil comprised of a primary helically wound coil which is then wound into a specific secondary shape. The final shape upon deployment is in the approximate shape of an anatomical cavity. upon deployment, the device first fills the periphery of the cavity and then continues to infill the center. The device is a self-forming shape made from a pre-formed linear helically wound. Fibers may be introduced onto the device and affixed to the pre-formed linear member. The constituent member may be also be covered with a fibrous braid. The device is typically introduced through a catheter. The device is passed axially through the catheter sheath and assumes its form upon exiting the catheter without further action. The invention also includes methods of winding the vaso-occlusive device into appropriately shaped forms and annealing them.

International Classification:

A61M 2900

US Classification:

606191

Abstract:

This is a surgical device that, in particular, is for forming a vasoocclusion or embolism. Typically, it is a helically wound coil in which the helix is wound in such a way as to have multiple axially offset, longitudinal or focal axes. Another important facet of the invention is the presence of small diameter secondary coil windings adjacent large diameter coil windings. The device is sufficiently flexible and small that it may be delivered to a site within the vasculature of the human body using a pusher and a catheter. The device is generally linear when within the catheter but relaxes to form the multi-focal form after delivery from the distal end of the catheter lumen. Various mechanical connections may also be used to discharge the inventive coil from its pusher. Similarly, the coil may be attached to a pusher using a sacrificial joint, which sacrificial joint is dissolved by imposition of a small voltage within the human body. The device may be used alone or in conjunction with other coils or with a fibrous thrombotic attachments or the substrate to localize subsequent infusion of tissue adhesives, other particulate embolization devices, or chemotherapeutic agents in abnormal blood vessels and tissues.
