Abstract: A guidewire with collapsible filter system and method of use where a deployable, collapsible and retrievable filter attached to a guidewire tube is utilized for filtering thrombotic particulate from blood flow in the vascular system during thrombectomy or other interventional vascular procedures.

Abstract: An occlusive guidewire system having an ergonomic handheld control mechanism prepackaged in a pressurized gaseous environment and a compatible prepackaged torqueable kink-resistant guidewire with distal occlusive balloon. Convenient structure and overall mechanism for operation of a torqueable kink-resistant guidewire with a distal occlusive balloon, including evacuation and inflation control of the distal occlusive balloon, and sealing and severing of a crimpable inflation tube which is in communication with the occlusive balloon. Torqueable kink-resistant guidewires include centrally located structure which imparts robustness to the torqueable kink-resistant guidewires. An inflation lumen aligns within the torqueable kink-resistant guidewires for inflation of the occlusive balloon.
