RHEOLYTIC THROMBECTOMY CATHETER WITH SELF-INFLATING PROXIMAL BALLOON WITH DRUG INFUSION CAPABILITIES

摘要

The present disclosure involves a rheolytic thrombectomy catheter with a self-inflating proximal balloon having drug infusion capabilities. A self-inflating balloon having a plurality of outflow orifices located about the peripheral circumference thereof is located proximal to an inflow gap or orifices and a fluid jet emanator and which balloon is inflated and expanded by internal operating pressures to uniformly space and position the outflow orifices of the self-inflating balloon in close proximity to or in intimate contact with the thrombus or walls of the blood vessel. Devices of the present disclosure can be used for the purposes of thrombectomies, embolectomies, thrombus or vessel dilation and for the delivery of drugs to a thrombus or vessel site.
