    摘要： A medical guidewire (28) includes a flexible spiral coil (52) , a fiber (54), and a strengthening element. The coil is configured to guide a medical device into a patient body. The fiber extends along at least part of the coil, is coupled to the at least part of the coil at one or more first predefined locations and is configured to mechanically strengthen the at least part of the coil. The strengthening element is coupled to one or more second predefined locations along a distal section of the coil, and is configured to mechanically strengthen the distal section.

    摘要： To provide a catheter with excellent torque transmissivity and excellent flexibility, enabling easy insertion into a blocked portion of a blood vessel or the like, and allowing the catheter to easily restore its original form even when a degree of curvature of the catheter becomes large and the catheter is deformed, thereby preventing a break at a border area between a catheter main body and a distal end tip and improving the operability of a combination device such as a guide wire. A catheter (1) includes a coil body (20) formed of at least one stranded wire (30) which is formed of a first wire (31a) and a plurality of second wires (31b) and is wound into a hollow helical coil structure.

    摘要： Un cathéter vasculaire (10) comprend un corps de cathéter (12) à l'extrémité distale (16) duquel est attaché un fil de guidage fixe (40). Le fil de guidage fixe (40) comprend un passage axial (42) lequel est aligné avec un passage du fil (46) se trouvant à l'intérieur du corps du cathéter (12) de sorte que ledit cathéter vasculaire (10) peut être introduit dans le système vasculaire par un fil de guidage mobile (48). Le corps (12) du cathéter comprend typiquement un tube flexible (12) à l'extrémité distale (16) duquel est fixé un logement (24). On peut loger à l'intérieur dudit logement une variété de dispositifs d'intervention parmi lesquels des dispositifs thérapeutiques et diagnostiques. L'emploi à la fois d'un fil de guidage fixe (40) et d'un fil de guidage mobile (48) facilite l'introduction initiale de cathéters vasculaires de gros diamètre, tout en permettant un repositionnement ultérieur des cathéters après le retrait dudit fil de guidage mobile (48).

    摘要： A catheter for balloon angioplasty includes a flexible shaft (12) defining a hollow passage (18), the shaft having first (14) and second (16) ends. A core means (20) is movably and removably mounted within the hollow passage, the core means having first and second ends adjacent the first and second ends of the shaft. The core means has a first flexible portion (26) adjacent the first end and a second flexible portion (28) of greater flexibility adjacent the second end. The core means may also have an enlarged terminal knob (30) at the second end. A flexible guide wire (32) may be fixed to the second end of either the shaft or the core means. The catheter may be inserted into a vascular tree. After removal of the core means, the core means may be replaced by an exchange wire, an angioscope, a laser fiber, or a rotatable wire. Also, when the core means is replaced by an exchange wire, the shaft may then be removed and replaced by either a different balloon angioplasty catheter or a perfusion catheter.
