Aspiration catheters for thrombus removal
First Claim
1. An aspiration catheter comprising:
- an aspiration device,a proximal portion,a connection port connected to the proximal portion, wherein the connection port is connected to the aspiration device,a distal segment wherein the distal segment comprises a single lumen and wherein the distal segment comprises one or more polymers including at least one thermoplastic polymer forming a tubular element and metal wire reinforcement embedded in the polymer tubular element and extending around the tubular element, anda tube section connected between the distal segment and the proximal portion,wherein the distal segment has a constant outer diameter with a value that is from about 25 percent to about 95 percent of the average outer diameter of the tube section and comprises a distal opening at the distal end of the catheter,wherein the catheter comprises a continuous lumen extending from the proximal portion through the tube section and the distal segment to the distal opening that provides fluid communication between the aspiration device and the distal opening, and the portion of the continuous lumen inside the distal segment has a smaller diameter relative to the diameter of the portion of the continuous lumen inside the tube section, wherein the diameter of the distal segment is not extendible.

Abstract
Systems for less invasive medical procedures comprise a filter device mounted on an integrated guiding structure and an aspiration catheter. These components can be used together or separately, and the system can be used with other medical devices that are designed for less invasive procedures, such as procedures in a patient'"'"'s vasculature. The catheter can have a radiopaque band that is held in place under metal wire embedded within the polymer forming the tube of the catheter. In some embodiments, the aspiration catheter has a small diameter distal portion that can access into small diameter vessels in which the distal portion has a smaller average diameter than the remaining tube of the catheter.
