Dec 30, 1998

Appl. No.:

09/223223

Inventors:

Mark Richardson - Escondido CA
Emmanuel C. Biagtan - Temecula CA

Assignee:

Advanced Cardiovascular Systems, Inc. - Santa Clara CA

International Classification:

A61B 500

US Classification:

600585

Abstract:

The invention is directed to a guide wire having at least two different polymeric jackets that impart different handling characteristics to the portions of the guide wire they surround. Preferably, the guide wire may have jackets of different grades of polymer, such as polyurethane 55 D and 90 A.

International Classification:

A61B 500

US Classification:

600585

Abstract:

A guidewire or section thereof, that has a core member or the like with a plurality of contiguous tapered segments having taper angles that are configured to produce a linear change in stiffness over a longitudinal portion of the device. The device may also have a core section with a continuously changing taper angle to produce a curvilinear profile that is configured to produce a linear change in stiffness of the core over a longitudinal portion of the device. An embodiment has a plurality of radiopaque elements that may be intermittent, continuous or in the form of a helical ribbon for scaled measurement of intracorporeal structure under flouroscopic imaging. Another embodiment has at least one layer of polymer over the distal end of the device.

Appl. No.:

10/421213

Inventors:

Mark Richardson - Escondido CA, US
David Anderson - Temecula CA, US

Assignee:

Cardiac Pacemakers, Inc. - St. Paul MN

International Classification:

A61N 1/05

US Classification:

607119

Abstract:

An apparatus is usable for guiding and stabilizing a body implantable medical device. The apparatus includes a guide wire with an enlarged distal tip. The enlarged distal tip may include a compliant portion to prevent tissue abrasion or perforation. The implantable device includes an open lumen configured to longitudinally advance along the guide wire. A sleeve is disposed over the guide wire and slidably deployable over the enlarged tip of the guide wire. When the implantable device is in final position, the open lumen encompasses at least part of the enlarged tip of the guide wire. The sleeve can be moved over at least part of the enlarged tip and create an interference between the tip and the open lumen, thereby stabilizing the implantable device.

US Classification:

726 5

Abstract:

Systems and methods are disclosed for securely transferring research data relating to media exposure data, such as radio, television, streaming media and the Internet. A plurality of portable computing devices seek and bond to a collector via Bluetooth in a specific area, such as a household. The collector authenticates itself with each of the portable computing devices and vice versa where the collector arranges a secure research data transfer session with each respective device using exchanged authentication files. As each secure session is made, each portable computing device transmits stored research data during the session.

Abstract:

Intravascular devices, systems, and methods are disclosed. In some embodiments, side-loading electrical connectors for use with intravascular devices are provided. The side-loading electrical connector has at least one electrical contact configured to interface with an electrical connector of the intravascular device. A first connection piece of the side-loading electrical connector is movable relative to a second connection piece between an open position and a closed position, wherein in the open position an elongated opening is formed between the first and second connection pieces to facilitate insertion of the electrical connector between the first and second connection pieces in a direction transverse to a longitudinal axis of the intravascular device and wherein in the closed position the at least one electrical contact is electrically coupled to the at least one electrical connector received between the first and second connection pieces.
