Assignee:

BOSTON SCIENTIFIC SCIMED, INC. - Maple Grove MN

International Classification:

A61M 29/00
A61B 17/58

US Classification:

606200, 606103

Abstract:

A device for delivering an occlusive element includes an elongate sheath. A distal blocking member is located at the distal end of the elongate sheath and includes an aperture therein. An elongate releasing member is disposed within a lumen of the elongate sheath. The elongate releasing member includes a proximal end and a distal end with the distal end terminating in at least one retaining member. The device includes an occlusive element such as, for example, a vaso-occlusive coil that has a securing member located at a proximal end thereof. The securing member of the occlusive element passes through the aperture of the distal blocking member and the at least one retaining member is releasably secured to the securing member.

International Classification:

A61B 17/00

US Classification:

604 57, 606108

Abstract:

An implant assembly comprises an elongated pusher member, and an implantable device (e.g., a vaso-occlusive device) mounted to the distal end of the pusher member. The implant assembly further comprises an electrolytically severable joint disposed on the pusher member, wherein the implantable device detaches from the pusher member when the severable joint is severed, and a return electrode carried by the distal end of the pusher member (e.g., a coil disposed about the pusher member) in proximity to, but electrically isolated from, the severable joint. The implant assembly further comprises a terminal carried by the proximal end of the pusher member in electrical communication with the severable joint.

Assignee:

Boston Scientific Scimed, Inc. - Maple Grove MN

International Classification:

A61F 2/00

US Classification:

606108, 606 1, 606191

Abstract:

Electrolytically detachable implantable devices and methods of delivering the same to a treatment site. An assembly includes an implantable device, such as a vaso-occlusive coil, a conductive deployment mechanism, such as a conductive pusher or wire, and a temporary connection between the deployment mechanism and the coil in the form of an electrolytically detachable junction. The detachable junction includes fine wires, e.g., stainless steel wires having a small diameter of about 0.00001″ to about 0.0025″, for example, about 0.0005″. The pusher or wire is used to deliver the implantable device through a catheter and to a desired location or treatment site. After the implantable device is properly positioned, electrical current is applied to the fine wires, thereby simultaneously disintegrating the fine wires and leaving the coil at the treatment site.
