Abstract
A multi-cavity aspiration device for more efficiently aspirating multiple obstructions, clots, thrombi, emboli, or the like in a single aspiration stroke. The multi-cavity aspiration device may include a tubular member having an inner circumference. One or more cavities may be formed or cut into the inner circumference of the tubular member so as to increase surface area without affecting structural integrity. The one or more cavities may be positioned radially about the inner circumference of the lumen. The one or more cavities may be tapered proximally and terminate at a point. The one or more cavities may be exposed to the internal lumen of the tubular member.
Claims22
A multi-cavity aspiration device, comprising:
- a tubular member including a lumen having an inner circumference, the lumen having a uniform diameter along its length;
- and
- one or more cavities formed in the inner circumference of the tubular member at a distal end of the tubular member.
(canceled)
A multi-cavity aspiration system, comprising:
- an aspiration catheter comprising:
- a tubular member including a lumen having an outer circumference and an inner circumference;
- one or more cavities formed in the inner circumference of the tubular member near a distal end of the tubular member;
- and
- a radiopaque marker band attached to the outer circumference of the tubular member over the one or more cavities;
- and,
- an aspiration source connected to a proximal end of the aspiration catheter.
(canceled)
A medical device, comprising:
- a catheter having a proximal portion, a distal portion, and a lumen therebetween, and wherein the catheter has an inner diameter, an outer diameter, and a catheter sidewall therebetween;
- and
- one or more longitudinal cavities within the catheter sidewall at the distal portion of the catheter that are in fluid communication with the lumen;
- and
- a radiopaque marker band positioned around the distal portion of the catheter over the one or more longitudinal cavities.
