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 measurable 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.

A system for facilitating aspiration of a thrombus in a vessel, the system comprising:
- an automated motor pump configured to facilitate aspiration of the thrombus, the automated motor pump comprising an external control panel configured to receive input from an operator;
- and
- power electronics that power and control the automated motor pump to generate a plurality of stored suction patterns having a plurality of intensity levels,
- wherein the plurality of intensity levels comprises:
- a first intensity level having a first negative pressure between 100 and 350 mm Hg;
- a second intensity level having a second negative pressure between 351 and 550 mm Hg;
- and
- a third intensity level having a third negative pressure between 551 and 769 mm Hg;
- and
- wherein a first crescendo suction pattern of the plurality of stored suction patterns comprises a repetitive cycle comprising the first intensity level for a first duration, the second intensity level for a second duration after the first duration, and the third intensity level for a third duration after the second duration.
A system for facilitating aspiration of a thrombus in a vessel, the system comprising:
- a pump configured to facilitate aspiration of the thrombus;
- and
- power electronics configured to power and control the pump to generate a plurality of stored suction patterns having a plurality of intensity levels,
- wherein the plurality of intensity levels comprises:
- a first intensity level having a first negative pressure;
- a second intensity level having a second negative pressure, the second negative pressure being more negative than the first negative pressure;

- and
- wherein a first crescendo suction pattern of the plurality of stored suction patterns comprises the first intensity level for a first duration, the second intensity level for a second duration after the first duration, and the third intensity level for a third duration after the second duration.
A system for facilitating aspiration of a thrombus in a vessel, the system comprising:
- a pump that facilitates aspiration of the thrombus and generates a plurality of different stored suction patterns, wherein each suction pattern of the plurality of different stored suction patterns comprises a plurality of intensity levels,
- wherein the plurality of intensity levels comprises:
- a first intensity level having a first negative pressure;
- a second intensity level having a second negative pressure, the second negative pressure being larger than the first negative pressure;
- and
- a third intensity level having a third negative pressure, the third negative pressure being larger than the second negative pressure;
- and
- wherein a first suction pattern of the plurality of different stored suction patterns comprises the first intensity level for a first duration, the second intensity level for a second duration, and the third intensity level for a third duration.
