Abstract
Systems and methods can remove material of interest, including blood clots, from a body region, including but not limited to the circulatory system for the treatment of pulmonary embolism (PE), deep vein thrombosis (DVT), cerebrovascular embolism, and other vascular occlusions.
Claims20
A material capture system comprising:
- a first shaft defining a central lumen, the central lumen defining a central longitudinal axis;
- a second shaft configured to be positioned within the central lumen of the first shaft;
- and
- a body, a first end of the body defining an opening and a second end of the body fixedly attached to the second shaft,
- wherein the body is configured to be transformed from a compressed configuration to an expanded configuration in which the first end is expanded and the opening defines a radial center offset from the central longitudinal axis, and
- wherein a distalmost end of the second shaft is configured to extend distally of the opening when the body is in the expanded configuration.

A material capture system comprising:
- a first shaft defining a central lumen, the central lumen defining a central longitudinal axis;
- a second shaft configured to be positioned within the central lumen of the first shaft;
- a distal nose tip at a distal end of the second shaft;
- and
- a body, a first end of the body defining an opening and a second end of the body fixedly attached to the second shaft,
- wherein the body is configured to be transformed from a compressed configuration to an expanded configuration in which the first end is expanded and the opening defines a radial center offset from the central longitudinal axis,
- wherein the distal nose tip is configured to extend distally of the opening when the body is in the expanded configuration, and
- wherein the distal nose tip is tapered.

A material capture system comprising:
- a catheter including:
- a first shaft defining a central lumen, the central lumen defining a central longitudinal axis;
- a second shaft defining a guidewire lumen, the second shaft configured to be positioned within the central lumen of the first shaft;
- and
- a body, a first end of the body defining an opening and a second end of the body fixedly attached to the second shaft,
- wherein the body is configured to be transformed from a compressed configuration to an expanded configuration in which the first end is expanded and the opening defines a radial center offset from the central longitudinal axis, and
- wherein a distalmost end of the second shaft is configured to extend distally of the opening when the body is in the expanded configuration;
- and
- an expanding guide catheter including a funnel tip, wherein the funnel tip is configured to receive the body.

A material capture system comprising:
- a first shaft defining a central lumen, the central lumen defining a central longitudinal axis;
- a second shaft configured to be positioned within the central lumen of the first shaft;
- a distal nose tip at a distal end of the second shaft;
- and
- a body, a first end of the body defining an opening and a second end of the body fixedly attached to the second shaft,
- wherein the body is configured to be transformed from a compressed configuration to an expanded configuration in which the first end is expanded and the opening defines a radial center offset from the central longitudinal axis,
- wherein the distal nose tip is configured to extend distally of the opening when the body is in the expanded configuration, and
- wherein movement of the second shaft proximally relative to the first shaft causes the second end of the body to move proximally relative to the opening.
