Devices for transferring fluid to or from a subject include an extension tube assembly with an axially extending inner tube configured to couple to an elongate tubular cannula having opposing proximal and distal ends with an axially extending lumen and an axially extending inner tube. The inner tube extending through the tubular cannula defines an exposed needle tip and is in fluid communication with the inner tube of the extension tube assembly. The needle tip extends out of a distal end of the tubular cannula a suitable distance.

A device for interventions within the body, the device comprising: an end piece 6 for insertion into the body at a distal end thereof, the end piece 6 including a rigid lumen for holding an instrument 10 and guiding the instrument 10 to the distal end of the end piece; and a body section 4 supporting the lumen and being rigidly connected thereto, the body section including a navigation array 14 for guidance of the device using a surgical navigation system and/or including an anchor point 20 for a standard navigation array.

An apparatus (10) for minimally-invasive, including non-invasive, prevention and/or treatment of hydrocephalus and method for use of the same are disclosed. In one embodiment of the apparatus (10), a housing (50) is sized for superjacent contact with a skull having a fontanel. Within the housing (50), a compartment (12) includes a pressure applicator (88), such as a fluid-filled bladder (22), under the control of a pressure regulator (14). The pressure applicator (88) is configured to selectively apply an external pressure to the fontanel. The compartment (12) includes a pressure sensor (90) configured to measure intracranial pulse pressure of the fontanel. Further, in one embodiment, the apparatus (10) can cause pulse pressure modulation by adjusting the intracranial pulse pressure via the pressure applicator (88). This enables a non-invasive measurement of the pulse pressure and modulation thereof in infants, for example.

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.

Endovascular drug delivery systems and methods are disclosed herein for delivering a therapeutic agent to the intracranial subarachnoid space of a patient, and/or deploying an endovascular drug delivery device distal portion in the intracranial subarachnoid space and a portion of the drug delivery device body in a dural venous sinus such that a therapeutic agent is delivered from the deployed drug delivery device into the intracranial subarachnoid space.

A levelling device for positioning of a medical device in relation to a patient is disclosed. The levelling device comprises a tube having fluid communication between a first end and a second end, wherein the first end is configured for connection to the medical device and the second end is configured for connection to the patient. The levelling device comprises a control unit connected to a sensor, wherein the sensor is configured to transmit sensor data to the control unit which is indicative of a pressure difference between the first and second end of the tube, and an actuator connected to the control unit, wherein the actuator is configured to connect to the medical device and to arrange a position of the medical device in relation to the patient in dependence on said pressure difference.

Provided is a functional, low-profile intercranial device (LID). The LID includes a base portion; at least one cavity associated with the base portion and configured to accept at least one functional component; and at least one conduit having a first end in communication with the at least one cavity. The at least one functional component includes a medicinal, electronic, or optic therapeutic. The at least one conduit is configured to accept the medicinal therapeutic and a second end configured to dispense the therapeutic.

Methods, systems, and techniques for providing neurofeedback and for training brain wave function are provided. Example embodiments provide a Brain Training Feedback System (BTFS), which enables participants involved in brain training activities to learn to evoke/increase or suppress/inhibit certain brain wave activity based upon the desired task at hand. In one embodiment, the BTFS provides a brain/computer interaction feedback loop which monitors and measures EEG signals (brain activity) received from participant and provides feedback to participant. The BTFS may use an FFT based system or machine learning engines to deconstruct and classify brain wave signals. The machine learning based BTFS enable optimized feedback and rewards, adaptive feedback, and an ability to trigger interventions to assist in desired brain transitions.

Endovascular drug delivery systems and methods are disclosed herein for delivering a therapeutic agent to the intracranial subarachnoid space of a patient, and/or deploying an endovascular drug delivery device distal portion in the intracranial subarachnoid space and a portion of the drug delivery device body in a dural venous sinus such that a therapeutic agent is delivered from the deployed drug delivery device into the intracranial subarachnoid space.

A method and system for modulating a patient's responses to a medical intervention is provided. The method comprises provisioning a system with immersive content comprising visual content and associating at least one stimulation with the visual content, wherein the stimulation is selected from the group consisting of auditory stimulations, olfactory stimulations, gustatory stimulations, neurological stimulations, environmental stimulations, and tactile stimulations; allowing for the selection of an immersive experience from the immersive content; and responsive to said selection, rendering the immersive experience to the user by providing visual content to the user via a display device, and performing at least one stimulation associated with the visual content.
