RHEOLYTIC THROMBECTOMY CATHETER WITH SELF-INFLATING PROXIMAL BALLOON WITH DRUG INFUSION CAPABILITIES
First Claim
1. A thrombectomy catheter comprising:
- a manifold having a central elongated tubular body with a proximal end and a distal end;
an elongated flexible catheter tube having a proximal end and a distal end, said proximal end of said catheter tube extending into and distally from said distal end of said central elongated tubular body of said manifold;
said elongated flexible catheter tube having an elongated distal section, said elongated distal section of said catheter tube having a proximal end and a distal end;
said proximal end of said elongated distal section being spaced from said distal end of said elongated flexible catheter tube by an inflow gap interposed between the elongated flexible catheter tube and the elongated distal section;
said elongated flexible catheter tube further having a section adjacent said distal end, said section forming a self-inflating balloon having a periphery with a plurality of outflow orifices in said periphery;
a fluid jet emanator having a plurality of spaced jet orifices, said fluid jet emanator secured within said proximal end of said elongated distal section;
an elongated flexible high pressure tube having a proximal end in fluid communication with a fluid source and the fluid jet emanator; and
wherein the self-inflating balloon is pressurized into an expanded configuration by a proximal flow of fluid from the fluid jet emanator.

Abstract
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.
