Abstract: A device for removing an obstruction from a lumen in a human or animal subject may include an inflatable balloon. The inflatable balloon may include a proximal tapered portion having a proximal taper angle, a central portion, and a distal tapered portion having a distal taper angle that is greater than the proximal taper angle. The balloon may also include at least one eversion feature on the proximal tapered portion and/or the distal tapered portion. The eversion feature may facilitate preferential eversion of the distal tapered portion into an inside of the balloon without the proximal tapered portion collapsing. Preferential eversion of the distal tapered portion may be provided by the differences in the distal and proximal taper angles and by one or more of a number of different types of eversion features.

Abstract: A device for removing a urinary tract stone from a ureter may include an outer shaft, an inner shaft extending coaxially within the outer shaft, a self-expanding wire basket attached to a basket shaft extending coaxially within the inner shaft, an inflatable balloon and a handle. The balloon may include a rounded distal tip. The handle may include an inversion slider coupled to the inner shaft and configured to actuate the inner shaft, thereby inverting the distal tip of the inflatable balloon to form a pocket adapted to receive a urinary tract stone. The handle may also include a basket slider coupled to the basket shaft and configured to actuate the basket shaft to move the wire basket in and out of the inner shaft. The basket slider and the inversion slider are coupled such that when the inversion slider is moved along the handle to invert the distal tip of the balloon, the basket slider moves automatically to retract the wire basket into the distal tip of the balloon.

Abstract: Disclosed systems, methods, and devices may include a system for removing a kidney stone from a ureter. The system may have an inner shaft extending coaxially within an outer shaft, a stone retention member shaft having a stone retention member and extending coaxially within the inner shaft, a wall protection member coupled to the outer shaft and the inner shaft, and a handle coupled with proximal ends of the outer shaft, the inner shaft, and the stone retention member shaft. The handle may include an eversion mechanism coupled to the inner shaft and configured to actuate the inner shaft, thereby everting the wall protection member to form a pocket adapted to receive a kidney stone. The system may also include a retention member mechanism coupled to the stone retention member shaft and configured to actuate the stone retention member shaft.
