METHODS AND SYSTEMS FOR TREATING HYDROCEPHALUS
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.
Methods and Systems for Treating Intracranial Hypertension and Related Indications Using An Optic Nerve Stent or Shunt
Embodiments of the present specification provide surgical methods and apparatuses to deploy at least one stent through an optic nerve sheath in order to maintain an opening/fenestration for intracranial fluid egress. The surgical method creates a fenestration, an opening, a slit, or a hole, through an optic nerve sheath of a human patient. The fenestration is created in a minimally invasive manner using an applicator, such as an endoscopic visualization apparatus, that includes a stent or shunt for deploying through the fenestration. The presently disclosed specification is indicated to treat papilledema and/or intracranial hypertension and to deliver therapeutic compositions through the optic nerve sheath.
Implantable Valve Assembly With Extended Lifespan
An implantable valve assembly including a drainage catheter having a central lumen transitioning into a plurality of distinct branch lumen made of a shape memory material. A bioabsorbable dip coating secures the distal end of the plural distinct branch lumen together in physical contact with one another. Each branch lumen has an outer perimeter comprising at least one of a first outer surface section and a second outer surface section. in a secured state with the plural distinct branch lumen held together by the dip coating fluid is prohibited from passing through the holes defined in the first outer surface section. Bioabsorbable blocking members disposed about the outer perimeter of the assembled branch lumen mask holes defined in the second outer surface section prohibiting fluid from entering therein. In a time staggered fashion, the bioabsorbable elements absorb exposing new holes through which the fluid drains.
SHUNT FLUSHERS AND RELATED METHODS
Systems and methods for flushing shunt systems are disclosed herein. In some embodiments, a flusher includes a pinch tube that extends over a flush dome such that a user can simultaneously close the pinch tube and actuate the flush dome with a single motion. Flushing and refill valves of the system can be disposed in a cartridge that is laterally-offset from the flush dome, advantageously reducing the height profile of the flusher. Flushers with integrated shunt valves are also disclosed, as are shunt systems with restricted and unrestricted modes for selectively limiting the instances in which a user can open an auxiliary flow path through the system.
Methods and apparatus for reducing localized circulatory system pressure
The present invention is thus directed to methods and apparatus for decreasing pressure in a first portion of a vessel of the cardiac structure of a patient by implanting a shunt communicating with an area outside said first portion, whereby a volume of blood sufficient to reduce pressure in said first portion is released.
Cerebrospinal fluid diversion for the treatment of chronic fatigue syndrome and fibromyalgia and use of RNFL thinning as a biomarker therefor
This application discloses methods and tools for the treatment of chronic fatigue syndrome (CFS) and fibromyalgia and the use of retinal nerve fiber layer thinning as a biomarker for the treatment.
System And Method For Valve Control
Disclosed is a system including a flow control assembly. The system may include a flow regulating shunt system, for various purposes. The flow control assembly may be controlled according to selected parameters and methods.
HYDROCEPHALUS SHUNT
The present disclosure provides a hydrocephalus shunt including a ventricular catheter portion having an omniphobic surface. The ventricular catheter portion comprising: a proximal end portion and a distal end portion; wherein the proximal end portion is comprised of fluoropolymer tubing and the distal end portion is comprised of tubing that is comprised of a second material selected from the group consisting of a non-fluorinated polymer, non-perfluorinated polymer, silicone elastomer, fluorosilicone elastomer, or perfluorosilicone elastomer.
Drain Electrode
A method for monitoring patients undergoing cSDH evacuation for spreading depolarization comprising the steps of: placing a subdural electrode strip and drain tube having a distal tip on the cortex of the patient, and a method and device wherein, at the time of surgery, a subdural assembly comprising a drainage tube and an electrode strip is placed between the brain and skull of a patient undergoing cSDH evacuation.
Method of removing fluid from the body, and device therefore
A method for removing bodily fluid includes drawing bodily fluid that has accumulated in excess, converting the drawn fluid from bulk liquid form to aerosol form, and disposing of the aerosol via evaporation of liquid droplets and absorption and/or diffusion of vapor. Conversion from bulk liquid to aerosol may include collecting the bulk liquid fluid in a reservoir, conveying the bulk liquid bodily fluid to an atomizer, converting the bulk liquid fluid into an aerosol having ultrafine droplets, and ejecting the aerosol into a subcutaneous space for disposal via evaporation of liquid droplets and absorption and/or diffusion of vapors. The method may be performed with a subcutaneous atomizer that may be controlled locally or by an external transmitter for effecting a conversion and mist rate to keep pace with the accumulation of excess bodily fluid.
