Patent number: 11701170Abstract: Medical methods and devices for treating aortic dissections. A catheter-based cutting device permits cutting a septum of acute or chronic aortic dissections, in a retrograde manner. The catheter includes a base section having a central lumen therethrough and two flexible arms extending from a distal end thereof. The flexible arms can each have a guide wire channel therethrough. With distal ends of the two flexible arms separated, the two arms form a Y-shape with the base section. In one embodiment, with distal ends of the two flexible arms together, the two arms have a longitudinal profile, about a periphery thereof, identical to a longitudinal profile of the base section. A cutting component resides between the two arms. The cutting component can face distally outward between the two arms with the distal ends of the two flexible arms separated.Type: GrantFiled: April 3, 2020Date of Patent: July 18, 2023Assignee: CUTCATH LLCInventors: Ramon Berguer, Juan Parodi, Gene Parunak, Adrienne R.

Publication number: 20220039751Abstract: An anorectal expulsion device includes a balloon having a wall that extends between proximal and distal ends of the balloon and defines a balloon interior. The balloon interior contains a self-expanding, low compression-set material (e.g., open cell foam). The device also includes a catheter that extends through the proximal end of the balloon and at least a portion of the balloon interior. An interior of the catheter is in fluid communication with the balloon interior. The device also includes a termination component (e.g., a cap or a valve) coupled to the catheter at a position along the catheter that is outside of and proximal to the proximal end of the balloon (e.g., at the proximal end of the catheter). The physical configuration of the termination component is adjustable, and controls whether the balloon interior is in fluid communication with the external environment.Type: ApplicationFiled: September 9, 2019Publication date: February 10, 2022Inventors: William D.

Publication number: 20210252199Abstract: An apparatus including a hollow body, an inlet fluidly coupled to the hollow body, a piston slidably engaged within the hollow body, and a filter module arranged within the hollow body between the inlet and piston. The piston and hollow body cooperatively generate a negative pressure, relative to ambient, within the hollow body during distal piston translation from a first position to a second position, thereby drawing a fluid, such as blood, through the filter module into the hollow body. The piston and hollow body cooperatively generate a positive pressure, relative to ambient, within the hollow body during piston translation from the second position to the first position to egress the filtered fluid from the hollow body. The filter module may include a filter housing, a filter medium disposed within the housing, and a body valve configured to seal an open distal face of the filter housing.Type: ApplicationFiled: May 3, 2021Publication date: August 19, 2021Inventors: Theresa Fisher, Gene Parunak, Rick Routson, Steve Meines, Gillian Henker, Caitlin Winget, Rajen Kumar
