Filed:

Oct 1, 2003

Appl. No.:

10/677715

Inventors:

Neil Williams - Newark DE, US
Keith Levesque - Oxford PA, US
Richard Martin - Newark DE, US

International Classification:

G01V003/00

US Classification:

324318000, 324322000

Abstract:

An MR coil array made of a plurality of circuits having a conductive trace mounted on a substrate, each of the circuits adapted to generate a signal; and means in each substrate for attaching and aligning at least two of the circuits to one another. Preferably the means for attaching and aligning the circuits are holes or openings formed in the substrates, designed to mate with corresponding holes or openings in the other substrates. In a preferred embodiment, the coil array also includes means disposed on each of the circuits for pre-amplifying the signal.

Abstract:

A vasculature device with a wire with a shaped set portion, an electrically conductive path, an electrical connector connecting the wire to the electrically conductive path at a point distal to the shaped set portion, and a hypotube encasing the wire, electrically conductive path and electrical connector is provided. The vasculature device can be actuated from a low-profile configuration to a deployed configuration by heating of the wire, and in particular the shaped set portion of the wire, via application of an electrical current to the wire. The vasculature device is useful in removal of clots, thromboemboli and foreign bodies from the vasculature, and in particular the cerebral vasculature, and as steering wires or guidewires.
