US Patent:

20080228215, Sep 18, 2008

Filed:

Feb 27, 2008

Appl. No.:

12/038730

Inventors:

Brian Michael Strauss - Trabuco Canyon CA, US
Todd Jeffrey Hewitt - Laguna Niguel CA, US
Ramon Torres Carrillo - Santa Ana CA, US
Khoa Dang Vu - Santa Ana CA, US
William Robert Patterson - Irvine CA, US
Stacy Leon Faught - Aliso Viejo CA, US

Vince Divino - Mission Viejo CA, US

International Classification:

A61F 2/00

US Classification:

606191

Abstract:

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.

US Classification:

606191, 242590

Abstract:

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.

International Classification:

A61B 17/00

US Classification:

606 1

Abstract:

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.

International Classification:

A61F 2/95

Abstract:

Medical device delivery devices, systems, and methods are disclosed herein. According to some embodiments, a medical device delivery system includes a core member and a coupling assembly positioned about the core member. The coupling assembly may include an engagement member having projections configured to engage a medical device and a release member that is movable between a compressed configuration and an expanded configuration. A medical device can extend along the core member such that, when the release member is in the compressed configuration, the projections of the engagement member engage the medical device and when the release member is in the expanded configuration, the release member prevents the projections from engaging the medical device and/or facilitates expansion of the medical device.
