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.

A device for treating a thrombus in a vessel, the device comprising:
- a distal portion comprising a plurality of wires woven to form a textile structure expandable from a collapsed configuration to an expanded configuration,
- the textile structure comprising, in the expanded configuration:
- a first bulb,
- a second bulb distal to the first bulb, the first bulb and the second bulb having a first diameter,
- a first neck longitudinally between the first bulb and the second bulb,
- a third bulb distal to the second bulb,
- a second neck longitudinally between the second bulb and the third bulb,
- a fourth bulb distal to the third bulb, the third bulb and the fourth bulb having a second diameter smaller than the first diameter,
- a third neck longitudinally between the third bulb and the fourth bulb,
- a fifth bulb distal to the fourth bulb,
- a fourth neck longitudinally between the fourth bulb and the fifth bulb,
- a sixth bulb distal to the fifth bulb;
- the fifth bulb and the sixth bulb having a third diameter smaller than the second diameter, and
- a fifth neck longitudinally between the fifth bulb and the sixth bulb;
- the plurality of wires comprising:
- a plurality of shape-memory wires, and
- a plurality of radiopaque wires;
- a proximal portion including a tubular member, the tubular member comprising:
- a wire;
- and
- a hypotube comprising a lumen, the hypotube distal to the wire,
- wherein a portion of the wire is coupled inside the lumen of the hypotube;
- and
- a bonding zone coupling the distal portion and the proximal portion.
A device for treating a thrombus in a vessel, the device comprising:
- a first portion comprising a plurality of wires woven to form a textile structure expandable from a collapsed configuration to an expanded configuration,
- the textile structure comprising, in the expanded configuration:
- four to twenty self-expanding bulbs, wherein the four to twenty self-expanding bulbs comprises:
- a first bulb;
- a second bulb distal to the first bulb, the first bulb and the second bulb having a first diameter;
- a third bulb distal to the second bulb;
- and
- a fourth bulb distal to the third bulb, the third bulb and the fourth bulb having a second diameter smaller than the first diameter;
- a plurality of necks,
- pairs of the four to twenty self-expanding bulbs spaced along a longitudinal axis of the textile structure by a neck of the plurality of necks,
- the plurality of wires comprising shape-memory wires;
- a second portion including a tubular member;
- and
- a bonding zone coupling the first portion and the second portion.
