First Claim
Patent Images
1. A catheter for insertion into the arterial passage comprising:
- a flexible tube-like base member having an enlarged distal end portion, said distal end portion including side walls defining an open ended cavity;
a plurality of side wall openings communicatively connecting said cavity with said arterial passage;
inflatable balloon means encircling said enlarged distal end portion between said side wall openings and said open end of said cavity;
self actuating valve means operatively disposed within said cavity permitting blood to flow from the open end of said cavity through the side wall openings while arresting flow in the opposite direction;
air passage means communicating with said inflatable balloon means; and
fluid passage means communicating with said distal end portion, whereby when said catheter is inserted into an arterial passage said inflatable means can be inflated to wedge the same against the vessel wall to both hold the same in place and to prevent undesirable blood backflow.

Abstract
An arterial catheter of the multi-lumen type having an inflatable balloon portion to wedge the catheter in place against the arterial wall. Multi-infusions are allowed through the segmented multi-lumens. This catheter is so designed to allow blood to flow in the arterial system with the catheter in place. During diastolic phases, the blood flow will be closed off with movable plastic valves.
