  • HYBRID STENT AND STENT RETRIEVER
    Publication number: 20240156624
    Abstract: A stent including a hybrid network cluster of open cells and closed cells arranged wherein said closed cells are connected in a configuration to be resheathable. Open cells are not connected and the stent can be unsheathed to enhance flexibility. In one embodiment a ring of proximal closed cells are tapered and the stent is retrievable by engagement of a pushwire assembly.

  • Methods and apparatus for deploying ureteral stents
    Patent number: 8911450
    Abstract: A ureteral decompression device comprises a guide member and an anchoring structure. The guide member may be introduced through the urethra and bladder into the ureter so that the anchor structure passes a lodged kidney stone. Once past the stone, the anchor structure can be compacted to anchor the guide member in place. The anchor structure will permit leakage and the guide member will provide a leakage path directly past the stone, thus decompressing the kidney.
