Systems and methods for deploying an implant in the vasculature
First Claim
1. A system for treating a patient, comprising:
- an implant configured for deployment through a venous system of the patient, the implant comprising a proximal portion, a distal portion having a distal anchoring mechanism, and a lumen providing fluid communication between the proximal portion and one or more distal openings in the distal portion; and
a delivery system configured for creating an anastomosis between an inferior petrosal sinus and a subarachnoid space of the patient, and for deploying the implant in the anastomosis with the distal portion of the implant positioned in the subarachnoid space, such that, when the implant is deployed in the anastomosis, the implant lumen provides a fluid communication pathway between the proximal portion of the implant and the subarachnoid space of the patient.

Abstract
Methods for treating hydrocephalus using a shunt, the shunt having one or more CSF intake openings in a distal portion, a valve disposed in a proximal portion of the shunt, and a lumen extending between the one or more CSF intake openings and the valve, the method comprises deploying the shunt in a body of a patient so that the distal portion of the shunt is at least partially disposed within a CP angle cistern, a body of the shunt is at least partially disposed within an IPS of the patient, and the proximal portion of the shunt is at least partially disposed within or proximate to a JV of the patient, wherein, after deployment of the shunt, CSF flows from the CP angle cistern to the JV via the shunt lumen at a flow rate in a range of 5 ml per hour to 15 ml per hour.

15. An implant configured for being deployed in an inferior petrosal sinus (IPS) of a patient, the implant comprising:
-
a distal portion configured for being introduced into, and disposed within, a cerebellopontine (CP) angle cistern of the patient via the IPS; a proximal portion configured for being disposed within or otherwise in communication with a venous system of the patient; and a lumen extending from the distal portion to the proximal portion, wherein the lumen is in fluid communication with one or more openings in the distal portion, such that, when the implant is deployed in the IPS with the distal portion of the implant disposed within the CP angle cistern and the proximal portion of the implant disposed within or otherwise in communication with the patient'"'"'s venous system, the implant lumen provides a fluid communication pathway between the proximal portion of the implant and the subarachnoid space of the patient. - View Dependent Claims (16, 17, 18, 19, 20)
