  • Patent number: 9820764
    Abstract: The invention relates to systems for removing obstructions and other objects within a blood vessel or other interior lumen of an animal. The system may be deployed in the lumen from a catheter and includes a pull wire having a proximal end and a distal end, and a distal body having a proximal hub, a basket, and a distal hub. In some embodiments, the distal body includes a plurality of proximal strips that form a closeable claw that is used to capture the obstruction. In other embodiments, the basket includes an enlarged opening that allows the object to enter the basket. Optionally, the basket includes x-ray markers adjacent to the enlarged openings to allow the operator to locate the openings, as well as twisting strips that connect the basket to the proximal hub. The present invention also relates to methods of making and using such systems.

  • Patent number: 9566412
    Abstract: A method of making a platform of medical devices from a single tube of a memory metal is described. The single tube, which may be generally cylindrical, is cut to form perforations that function as scoring lines and are located adjacent to the proximal and distal ends. The perforations allow the manufacturer to cleanly tear proximal memory metal strips from each other and to cleanly tear distal memory metal strips from each other so that the freed proximal memory metal strips may be re-attached to each other and the freed distal memory metal strips may be re-attached to each other to form a medical device that may be positioned inside a catheter that has an inner diameter (ID) that is less than the outer diameter of the single tube. The formed medical device may be in the form of an expandable, shape-set basket with x-ray markers that may be used to remove an intracranial blood clot.

  • Patent number: 8900265
    Abstract: The present invention relates to a system for removing obstructions and other objects within a blood vessel or other interior lumen of an animal. The system may be deployed in the lumen from a catheter and includes a pull wire having a proximal end and a distal end, and a distal body. Optionally, the distal body includes a plurality of memory metal strips that form a closeable claw that is used to capture the obstruction. Optionally, the memory metal strips are connected to a proximal hub that is slideable along at least a segment of the pull wire and the memory metal strips are moved towards each other and towards the pull wire by moving the proximal hub distally towards a stationary distal hub, which in turn, causes the claw to close and capture the obstruction. The present invention also relates to methods of making and using such systems.
