Abstract
Aspiration catheters and systems are disclosed including a thrombectomy catheter which includes a catheter body extending from a proximal end region to a distal end region and includes a catheter lumen extending between the proximal end region and the distal end region. A high-pressure fluid supply tube may extend through the catheter lumen from the catheter body proximal end region toward the catheter body distal end region. The high-pressure fluid supply tube having a longitudinal axis and adapted for communication with a fluid source near the catheter body proximal end region and including a plurality of angled jet orifices with an elliptical cross-section oriented perpendicular to the longitudinal axis of the high-pressure fluid supply tube.
Claims20
A thrombectomy catheter, comprising:
- a catheter body extending from a proximal end region to a distal end region and including a catheter lumen extending between the proximal end region and the distal end region;
- a high-pressure fluid supply tube extending through the catheter lumen from the catheter body proximal end region toward the catheter body distal end region, the high-pressure fluid supply tube comprising a longitudinal axis and configured for communication with a fluid source near the catheter body proximal end region;
- a plurality of angled jet orifices for expelling a fluid jet from the high-pressure fluid supply tube within the catheter lumen in an angled direction non-perpendicular to the longitudinal axis;
- wherein one or more of the plurality of angled jet orifices have an elliptical cross-section in which a long axis of the elliptical cross-section is oriented perpendicular to the longitudinal axis of the high-pressure fluid supply tube.
A thrombectomy catheter, comprising:
- a catheter body extending from a proximal end region to a distal end region and including a catheter lumen extending between the proximal end region and the distal end region;
- a high-pressure fluid supply tube extending through the catheter lumen from the catheter body proximal end region toward the catheter body distal end region, the high-pressure fluid supply tube comprising a longitudinal axis and configured for communication with a fluid source near the catheter body proximal end region;
