| 摘要 |
The present invention provides endovascular brushes that include a brush segment at the distal end and a mandrel segment extending from the brush segment to the proximal end of the endovascular brush. The brush segment includes at least brush element, such as a fiber, bristle, loop, ridge, or corrugation, configured to provide a space or spaced for retaining cells biopsied with the endovascular brush and to reduce the thrombogenicity of the endovascular brush, which allows a user to safely obtain therewith endovascular tissue from a targeted vascular segment in-vivo.
