ENDOVASCULAR CATHETER WITH MULTIPLE CAPABILITIES

摘要

An endovascular catheter combination configured to have multiple capabilities is disclosed. These capabilities include proximal and distal occlusion of a segment of a target blood vessel (such as the carotid artery) thus excluding the segment of the blood vessel from circulation for purposes such as surgical consideration. Another capability includes intravascular shunting of the blood through the excluded portion of the artery during a procedure such as an endarterectomy. Additionally, a microsensor provides a measurement of the rate/volume of blood flow through the distal end of the catheter. In one embodiment, a guidewire is provided with a filtration mesh as an anti-embolic mechanism both at the time of initial positioning of the catheter and after reversing the occlusion.

主权项

1. An endovascular catheter comprising:
a flexible lumen with a leading end, a trailing end and a central portion disposed between the leading end and the trailing end; a first syringe and a second syringe, each disposed proximate the trailing end; at least one aperture in the central portion, the at least one aperture being fluidly connected to an opening at the leading end thereby providing a bypass; a common carotid balloon operatively connected to the first syringe; an internal carotid balloon operatively connected to the second syringe; and wherein the internal carotid balloon is disposed proximate the leading end and the common carotid balloon is disposed between the internal carotid balloon and the at least one aperture, the internal carotid balloon and the common carotid balloon being spaced apart by a distance.
