Guidewire with tubular connector |
摘要 |
An improved guidewire for advancing a catheter within a body lumen which has a high strength proximal core section, a flexible distal core section preferably formed of pseudoelastic alloy and a connecting element to provide a torque transmitting coupling between the distal end of the proximal core section and the proximal end of the distal core section. The ends of the core sections are secured within the inner lumen of the connecting element by means of a hardened mass of bonding material. The wall of the connecting element is provided with an opening to facilitate the introduction of the hardenable bonding material in the pourable state into the inner lumen of the connecting element. Preferably at least one of the ends of the core sections are configured, e.g. enlarged in at least one dimension compared to an adjacent part of the core section, to develop a mechanical interlock within the mass of hardened material.
