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.

(canceled)
A system for aspirating thrombi, the system comprising:
- a flexible catheter;
- a suction device configured to facilitate thrombus aspiration by generating at least a first suction pattern, wherein the first suction pattern comprises a plurality of intensity levels,
- wherein the first suction pattern may be selectable using an external control panel,
- and wherein the first suction pattern comprises a first intensity level for a first duration and a second intensity level for a second duration.
A system for aspirating thrombi using suction, comprising:
- a flexible catheter;
- and
- a suction device configured to transmit at least a first vacuum output to the distal end of the catheter,
- wherein the first vacuum output comprises a repetitive cycle pattern having at least one intensity level and at least one pause duration.
A system for aspirating thrombi using suction, comprising:
- a catheter comprising a proximal end, a distal end, and a lumen;
- and
- a suction control unit configured to transmit at least a first vacuum output at the distal end of the catheter,
- wherein the first vacuum output comprises a first intensity level for a first duration and a second intensity level for a second duration.
