Abstract
In some examples, a capture assembly configured to remove material of interest, including blood clots, from a body region, including but not limited to the circulatory system, includes a body configured to receive the material of interest. The body can be configured to axially lengthen and shorten.
Claims20
A material capture system comprising:
- a first shaft defining a central lumen;
- a second shaft comprising a distal tip, the second shaft configured to be positioned within the central lumen of the first shaft;
- and
- a body attached to the first shaft and the second shaft, the body defining:
- a fold point where the body everts;
- and
- a proximal-facing opening configured to receive a thrombus,
- wherein the body is configured to be transformed between:
- a first configuration in which the proximal-facing opening is expanded and a first axial distance separates the fold point and the distal tip, and
- a second configuration in which the proximal-facing opening is expanded and a second axial distance separates the fold point and the distal tip, the second axial distance being different than the first axial distance.

A material capture system comprising:
- a first shaft defining a central lumen;
- a second shaft comprising a distal tip, the second shaft configured to be positioned within the central lumen of the first shaft;
- and
- a body attached to the first shaft and the second shaft, the body defining:
- a fold point where the body everts;
- a proximal-facing opening at a first end of the body, the proximal-facing opening configured to receive a thrombus;
- and
- a second shaft attachment point spaced apart from the first end,
- wherein the body is attached to the second shaft at the second shaft attachment point, and
- wherein the body is configured to be transformed between:
- a first configuration in which the proximal-facing opening is expanded and a first axial distance separates the fold point and the distal tip, and
- a second configuration in which the proximal-facing opening is expanded and a second axial distance separates the fold point and the distal tip, the second axial distance being different than the first axial distance, and
- wherein in the first configuration and the second configuration, the distal tip of the second shaft is distal to the fold point.

A method comprising:
- positioning a material capture system near an obstruction, the material capture system comprising:
- a first shaft defining a central lumen,
- a second shaft comprising a distal tip, the second shaft configured to be positioned within the central lumen of the first shaft, and
- a body attached to the first shaft and the second shaft, the body defining:
- a fold point where the body everts, and
- a proximal-facing opening configured to receive a thrombus;
- and
- transforming the material capture system, for capturing the obstruction, between:
- a first configuration in which the proximal-facing opening is expanded and a first axial distance separates the fold point and the distal tip, and
- a second configuration in which the proximal-facing opening is expanded and a second axial distance separates the fold point and the distal tip, the second axial distance being different than the first axial distance.
