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
