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 ho 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.
Claims1
A funnel device for securing debris and/or devices within a vessel, the funnel device comprising:
- a shaft having a flexibility to navigate through tortuous anatomy and having a lumen extending therethrough;
- a funnel comprising a distal opening and a proximal portion connected to the shaft and a cavity therebetween such that when the funnel is expanded the funnel tapers in a proximal direction towards the shaft, the funnel comprising a mesh material secured to the shaft such that when expanded the mesh material forms a funnel configuration having at least an exterior mesh wall and an interior mesh wall that are shape;
- and
- where at least a portion of the mesh material is porous to permit fluid flow therethrough.
