Abstract
The devices and methods described herein relate to improved structures for removing obstructions from body lumens. Such devices have applicability in through-out the body, including clearing of blockages within the vasculature, by addressing the frictional resistance on the obstruction prior to attempting to translate and/or mobilize the obstruction within the body lumen.
Claims22
A device for deployment within a blood vessel using a catheter, the device comprising:
- a shaft having a distal end and a proximal end;
- a braided cover having a free and open distal section and a proximal end coupled to the shaft at a location proximal to the distal end of the shaft, wherein the proximal end comprises at least one peak pointing in a proximal direction and at least one valley pointing in a distal direction, wherein the braided cover is configured to self-expand against the vessel wall when deployed from the catheter;
- and
- an expandable helical coils within the braided cover and configured to conform to a profile of the braided cover.

A device for deployment within a blood vessel using a catheter, the device comprising:
- a shaft having a distal end and a proximal end;
- and
- a cover configured to self-expand into contact with the vessel wall when deployed from the catheter, the cover including:
- a mesh structure having a free and open distal section and a proximal end coupled to the shaft at a location proximal to the distal end of the shaft, wherein the proximal end comprises at least one peak pointing in a proximal direction and at least one valley pointing in a distal direction, and
- an expandable helical coils inside the mesh structure and configured to conform to a profile of the mesh structure.
