  • Patent number: 11154391
    Abstract: Provided is a ureteral stent for placement in a bladder, a kidney and a ureteral passageway connecting the bladder and the kidney. The ureteral stent includes a solid bladder portion free of a lumen positionable in the bladder, a tubular kidney portion positionable in the kidney and the ureteral passageway, and a tether connecting the bladder portion and the ureter portion to allow the bladder portion to float in the bladder and to allow a ureter orifice connecting the ureteral passageway to the bladder to move between a compressed state and an uncompressed state. By not having a lumen, the solid bladder portion allows the bladder to have a smaller diameter while maintaining a necessary uncoil force. The smaller diameter also allows the bladder portion to be inserted into a scope alongside a pusher tube, thereby avoiding loading the bladder portion onto a guidewire.

  • Patent number: 10925640
    Abstract: The present disclosure describes delivery cables for delivering a medical device. In one embodiment, a delivery cable includes a flexible inner core, a proximal outer coil, and a distal outer coil. The proximal outer coil has a first rigidity. The distal outer coil surrounds at least a portion of a distal section of the flexible inner core and has a second rigidity less than the first rigidity thereby, thereby reducing bias placed on the medical device by the delivery cable.

  • Patent number: 10881542
    Abstract: A stent delivery device for deploying a low column strength stent may include an inner member having a distal region and a stent receiving area disposed therein. A low column strength stent convertible between a compressed configuration and an expanded configuration may be disposed on the stent receiving area. The stent receiving area may include a soft durometer polymer configured to permit the low column strength stent to sink into the soft durometer polymer when the low column strength stent is in the compressed configuration. An outer member may be moveable between an extended position in which the outer member extends over the stent and a retracted position in which the outer member is proximal of the stent.
