Patent number: 11490912Abstract: A system for removing a kidney stone from a ureter may include: an elongate, flexible, outer shaft having a distal end configured to be advanced into the ureter and a proximal end; an elongate, flexible, inner shaft extending through at least part of the outer shaft; an expandable stone retention member extending through at least part of the inner shaft and moveable along the longitudinal axis relative to the inner shaft; an elongate, flexible camera positioned coaxially within the retention member shaft, such that a distal end of the camera is located at or near a distal end of the inner shaft; and a handle coupled with the proximal end of the outer shaft, a proximal end of the inner shaft, and a proximal end of the retention member shaft.Type: GrantFiled: May 31, 2019Date of Patent: November 8, 2022Assignee: Calcula Technologies, Inc.Inventors: Raymond Arthur Bonneau, David Gal, David Wellman Snow

Patent number: 10624657Abstract: 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.Type: GrantFiled: April 11, 2018Date of Patent: April 21, 2020Assignee: CALCULA TECHNOLOGIES, INC.Inventors: Raymond Arthur Bonneau, David Gal, David Wellman Snow
