Patent number: 11951270Abstract: Systems and methods for implanting an endovascular shunt in a patient is disclosed. The system having an expandable anchor configured for being deployed in a dural venous sinus of a patient at a location distal to a curved portion of a wall of an inferior petrosal sinus (IPS) of the patient; an elongate guide member coupled to, and extending proximally from, the anchor; a shunt delivery catheter having a first lumen configured to receive the guide member, and a second lumen extending between respective proximal and distal openings in the shunt delivery catheter, the shunt delivery catheter further having a penetrating element coupled to a distal end of the catheter; and the system further having a guard at least partially disposed over, and movable relative to, the penetrating element.Type: GrantFiled: August 5, 2020Date of Patent: April 9, 2024Assignee: CereVasc, LLCInventors: Adel M.

Publication number: 20200030588Abstract: An endovascular shunt implantation system includes a guide member configured for being deployed in an inferior petrosal sinus, and a delivery catheter movably coupled to the guide member, wherein a distal end of the delivery catheter includes a tissue penetrating element. A guard is disposed over the tissue penetrating element, the guard having an open distal end portion including an inner surface feature configured to deflect the tissue penetrating element away from the guide member when the tissue penetrating element is translated distally relative to the guard. A shunt delivery shuttle is positioned within, and is movable relative to, the delivery catheter, the shunt delivery shuttle having a distal portion configured to collapse around an elongate shunt body to thereby transport the shunt body through the delivery catheter, wherein the distal portion self-expands to release the shunt body when the distal shuttle portion is advanced out of the delivery catheter.Type: ApplicationFiled: October 11, 2017Publication date: January 30, 2020Applicant: CEREVASC, LLCInventors: Carl Heilman, Adel M. Malek, David A. Rezac, Jack B. Sattell, Alexander Bonin
