Abstract
The present disclosure relates to an intravascular device for thrombus removal. The device includes a core and a tube structure coupled to the distal section of the core. The tube structure includes a first, distal section and a second, proximal section. The device further includes a wire mesh located in a gapped region between the first section and the second section of the tube structure. The core is coupled to the first section of the tube structure but is free to move longitudinally relative to the second section of the tube structure. Application of a pulling force to the core can therefore selectively contract the wire mesh and cause it to radially expand to a position for contacting and removing a target thrombus.
Claims20
An intravascular device comprising:
- a core having a proximal section and a distal section;
- a tube structure coupled to the distal section of the core, wherein the tube structure comprises a first section and a second section, the second section being disposed proximal of the first section;
- and
- a wire mesh disposed in a gapped region of the tube structure, wherein the gapped region is disposed between the first section and the second section,
- wherein the core is coupled to the first section of the tube structure and is free to longitudinally translate relative to the second section of the tube structure such that when the core is moved proximally relative to the second section of the tube structure, the gapped region is collapsed, and the wire mesh is radially expanded.
An intravascular device comprising:
- a core having a proximal section and a distal section;
- a tube structure coupled to the distal section of the core, wherein the tube structure comprises a first section and a second section, the second section being disposed proximal of the first section;
- a wire mesh disposed in a gapped region of the tube structure, wherein the gapped region is disposed between the first section and the second section;
- a first radiopaque marker disposed at or near a distal tip of the device and longitudinally coincident with the first section of the tube structure;
- a second radiopaque marker longitudinally coincident with the wire mesh;
- and
- an actuation tube attached to a proximal end of the tube structure and extending proximally therefrom,
- wherein the core is coupled to the first section of the tube structure and is free to longitudinally translate relative to the second section of the tube structure and relative to the actuation tube such that when the core is moved proximally relative to the second section of the tube structure and relative to the actuation tube, the gapped region is collapsed, and the wire mesh is radially expanded.
