Beschreibung
Zusammenfassung:	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.
