Abstract: An aspiration thrombectomy catheter system includes an aspirator and an aspiration catheter for insertion in a blood vessel. The catheter has a shaft with a proximal end for connection with the aspirator and a tapering distal end with a tip for insertion in the vessel. A plurality of aspiration ports are arranged in sets along the tapering distal end, for aspirating thrombus from the vessel. At least one aspiration lumens within the shaft conducts thrombus from the vessel, through the aspiration ports, to the aspirator. Variably sized or shaped ports provide differing aspiration vectors for enhanced thrombus removal. The aspiration thrombectomy catheter additionally provides for uniform drug dispersion at a thrombotic area, alone or in combination with aspiration of the thrombus. In the event of an adverse reaction, drug dosage may be easily reduced by aspirating dispersed drugs back into the catheter.

Abstract: A pressure assist system for facilitating vascular hemostasis includes a support bar and a midbar extending perpendicularly from a middle portion of the support bar, for supporting a user's thumb when the user grasps the midbar. A base extends perpendicularly from a bottom of the support bar, for supporting the user's knuckles when the user grasps the midbar. A foot for pressing against a wound is configured with a bottom surface of the base. The midbar may be adjustable along the support bar, according to user grip preference. In a related method, a hand-held pressure assist system is provided, having a support bar, a midbar and base extending perpendicularly from the support bar, and a foot beneath the base. A use's thumb and knuckles are positioned over the midbar and base, respectively. The foot is placed over a wound and downward pressure is applied until hemostasis is achieved.
