An implantable medical device for delivering therapeutic fluid to, and withdrawing cerebrospinal fluid (CSF) from, a CSF-containing space, includes a first inlet configured to be accessed by a needle of an aspiration device; a first outlet; a first fluid pathway extending from the first inlet to the first outlet; a second inlet; a second outlet; and a second fluid pathway extending from the second inlet to the second outlet. The first fluid pathway is free of a filter configured to prevent passage of a microbe.

In some examples of a method of forming a catheter, a structural support member is positioned over an inner liner. Prior to being positioned over the inner liner, the structural support member tapers in diameter along at least a portion of a length of the structural support member.

Presented herein are implantable systems and methods for long-term delivery of treatment substance to a recipient.

An implantable cranial medical device includes a first fluid flow path, a second fluid flow path, and upper flange portion, and a lower portion. The upper flange portion is configured to rest on a skull of a subject about a burr hole. The lower portion is configured to be placed within the burr hole. The first fluid flow path may extend from a first opening in the upper flange portion to a first opening in the lower portion. The second fluid flow path may extend from a second opening in the upper flange portion to a second opening in the lower portion.

A system and method for providing sensory relief from distractibility, inattention, anxiety, fatigue, and/or sensory issues to a user in need. The user can be autistic/neurodiverse, or neurotypical. The system can be configured to connect to a datastore storing one or more sensory thresholds specific to a user of a wearable device of the system, the sensory thresholds selected from auditory, visual or physiological sensory thresholds; record, using one or more sensors of the wearable device, a sensory input stimulus to the user; compare the sensory input stimulus with the sensory thresholds to determine an intervention to be provided to the user, the intervention configured to provide the user relief from distractibility, inattention, anxiety, fatigue, or sensory issues; and provide the intervention to the user, the intervention comprising filtering, in real-time, an audio signal presented to the user or an optical signal presented to the user.

The present invention provides a skull implant-type automatic fluid drain device comprising: a body having a first port to be connected to a catheter, a second port provided opposite the first port, and a flow passage connecting the first port and the second port; a separation member for separating the flow passage into first and second sub-channels; a first valve fixed to the separation member and provided to allow the movement of a fluid that moves from the first port to the second port in the first sub-channel; and a second valve fixed to the separation member and provided to allow the movement of a fluid that moves from the second port to the first port in the second sub-channel, wherein each of the first valve and the second valve has an inflow end portion that is open and a discharge end portion provided in a closed state such that the same is selectively opened at an allowed opening pressure or higher; each of the first valve and the second valve is configured such that the inner flow sectional area decreases along the direction of allowed movement of the fluid passing through each of the inflow end portion and the discharge end portion; and the allowed opening pressures of the first valve and the second valve are set to differ from each other.

A device, system, and method for facilitating a sleep cycle in a subject during a pandemic or peri COVID vaccination period, comprising determining a current awake or sleep stage of a person; automatically defining a desired sleep cycle pattern, dependent on the current awake or sleep stage of the person; generating an audio or optical stimulation pattern by an automated processor; and entraining brainwaves of the brain of the person with the stimulation pattern corresponding to the desired sleep cycle pattern, to thereby induce a sleep cycle in the person according to the sleep cycle pattern. When sleep patterns are normalized, a SARS-Cov-2 vaccination may be administered to the person.

A percutaneous fluid access apparatus includes a percutaneous fluid access device. The percutaneous fluid access device has a base portion including a subcutaneous portion and at least one port for connection to one or more fluid conduits within a body of a patient. A housing has at least one fluid channel and at least one seal for sealing the at least one fluid channel, and the housing is removably attachable to the base portion. The at least one fluid channel is in fluid communication with the at least one port when the housing is attached to the base portion.

A method for treating an aneurysm in accordance with a particular embodiment of the present technology includes intravascularly delivering a mixture including a biopolymer (e.g., chitosan) and a chemical crosslinking agent (e.g., genipin) to an aneurysm. The method further includes mixing the biopolymer and the chemical crosslinking agent to initiate chemical crosslinking of the biopolymer. The mixture is delivered to the aneurysm via a lumen and an exit port of a catheter while the chemical crosslinking is ongoing. The mixture exits the catheter as a single cohesive strand that at least partially agglomerates to form a mass occupying at least 75% of a total internal volume of the aneurysm. During delivery of the mixture, the method includes expanding a tubular flow diverter to reinforce a neck of the aneurysm.

An apparatus for guiding the migration of cancer and other cells includes a reservoir device, a cover, a tube, a nanofiber structure, and a lock device. The reservoir device defines a reservoir having an open top. The cover is configured for removable installation over the open top of the reservoir. The tube has a proximal end portion reaching into the reservoir. The nanofiber structure communicates an inlet port in the tube with the reservoir. The lock device interlocks the tube with the reservoir device, and also interlocks the nanofiber structure with the reservoir device.
