Publication number: 20070198044Abstract: A guide wire (1) for re-canalising a vascular occlusion comprises a core wire (5) which terminates at its distal end (4) in a terminal member (7) for opening the occlusion. A helical coil sleeve (10) extends around the core wire (5) from the terminal member (7) to a location (11) along the core wire (5). The terminal member (7) defines first and second planar surface portions (13,14) which converge towards a distal transversely extending leading edge portion (8). As the terminal member (7) is urged through the vascular occlusion, the first and second surface portions (13,14) act on the occlusion to form an opening therethrough. A distal portion (28) of the core wire (5) is of spade-like configuration for facilitating bending thereof for directing the terminal member (7) out of a central major plane (35) defined by the distal portion (28) for facilitating aligning of the terminal member (7) with a branched vessel of the vascular system.Type: ApplicationFiled: March 24, 2005Publication date: August 23, 2007Inventors: Henry Lupton, Mark Bruzzi

Publication number: 20070032744Abstract: A guide wire (1) for use with a catheter comprises a core wire (3) terminating in a distal portion (18) of flat ribbon-like construction having respective opposite major surfaces (29,30). A spring (24) is brazed to a distal end (27) of the distal portion (18) and to the core wire (3) at a tapering portion (14). A reinforcing member (38) extends axially along the distal portion (18) from a proximal end (26) of the distal portion (18) to a location (40) for reinforcing the distal portion (18) for in turn increasing its torsional rigidity in order to minimise axial twisting of the distal portion (18).Type: ApplicationFiled: December 19, 2003Publication date: February 8, 2007Inventor: Henry Lupton

Publication number: 20060264784Abstract: A guide wire (1) for use with a catheter for accessing a remote site in the venal or other system of the body of a human or animal subject comprises a core wire (2) extending from a proximal end (5) to a distal end (6). The core wire (2) terminates at the distal end (6) in a distal portion (16) which is of rectangular transverse cross-section defining a pair of opposite major surfaces (18,19) and minor surfaces (20,21). The distal portion (16) also defines a central major plane (24) which lies between the major surfaces (18,19) and bisects the minor surfaces (20,21), and a central minor plane (25) which lies between the minor surfaces (20,21) and bisects the major surfaces (18,19).Type: ApplicationFiled: August 9, 2004Publication date: November 23, 2006Inventor: Henry Lupton

Publication number: 20060247556Abstract: A guide wire (1) extending between a distal end (3) and a proximal end (4) defines a central axis (5). A main tubular member (6) of the guide wire (1) terminates in a curvature controllable portion (15) adjacent the distal end (3) for facilitating inducing a curvature therein for offsetting the distal end (3) at an angle (?1,?2) relative to the central axis (5). A first member (19) of the curvature controllable portion (15) and a second member (21) thereof are secured to a bulbous tip (7) at the distal end (3), and the second member (21) is slideable in the direction of the arrows A and C relative to the first member (19) for inducing curvature in the curvature controllable portion (15) for in turn offsetting the distal end (3) in the direction of the arrows B and D, respectively, from the central axis (5).Type: ApplicationFiled: August 6, 2004Publication date: November 2, 2006Inventor: Henry Lupton
