Systems and methods for treating hydrocephalus
First Claim
1. A system for implanting an endovascular shunt in a patient, comprising:
- 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 comprising 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,a penetrating element coupled to a distal end of the shunt delivery catheter; and
a guard at least partially disposed over, and movable relative to, the penetrating element, wherein the guard comprisesa tubular guard body having a first guard body lumen or recess configured to receive the penetrating element, anda pull wire having a distal portion attached to the guard body, wherein the pull wire is configured to translate the guard body proximally or distally relative to the shunt delivery catheter so as to at least partially expose or cover, respectively, the penetrating element.
