Abstract
Vascular treatment devices and methods include a woven structure including a plurality of bulbs that may be self-expanding, a hypotube, for example including interspersed patterns of longitudinally spaced rows of kerfs, and a bonding zone between the woven structure and the hypotube. The woven structure may include patterns of radiopaque filaments measureable under x-ray. Structures may be heat treated to include various shapes at different temperatures. The woven structure may be deployable to implant in a vessel. A catheter may include a hypotube including interspersed patterns of longitudinally spaced rows of kerfs and optionally a balloon. Laser cutting systems may include fluid flow systems.
Claims18
A system for facilitating aspiration of blood clots from vasculature within a body, the system comprising:
- a flexible catheter comprising an atraumatic distal tip and an open working lumen;
- and
- a negative suction device comprising a control unit configured to generate one or a plurality of suction outputs;
- wherein at least one suction output of the one or the plurality of suction outputs comprises a plurality of intensity levels,
- wherein the plurality of intensity levels comprises a first intensity level and a second intensity level, and
- wherein the at least one suction output comprises a repetitive cycle of the first intensity level having a first negative pressure and the second intensity level having a second negative pressure different than the first negative pressure.
A system for facilitating aspiration of blood clots from vasculature within a body, the system comprising:
- a flexible catheter comprising an atraumatic distal tip and an open working lumen;
- and
- a negative suction device comprising a control unit configurable to generate one or a plurality of suction outputs, wherein the control unit is configured to transmit at least one suction output through the open working lumen of the flexible catheter, wherein the at least one suction output includes a plurality of intensity levels.
A system for facilitating aspiration of blood clots from vasculature within a body, the system comprising:
- a flexible catheter comprising an atraumatic distal tip and an open working lumen;
- and
- a negative suction device comprising a control unit configured to generate negative suction to be applied through the open working lumen of the flexible catheter,
- wherein the negative suction applied has a repetitive suction pattern.
