A port catheter includes a port housing and a port chamber formed in the port housing and closed by a septum. The port catheter also includes a first catheter connection communicating with the port chamber for the connection of a first catheter, a second catheter connection for connecting a second catheter connected to an infusion pump and supplying a fluid to the port catheter from the infusion pump, and a third catheter connection communicating with the second catheter connection for connecting a third catheter which discharges the fluid supplied by the infusion pump.

Described herein is the use of CSF, more particularly external CSF or CSF-like compositions for the treatment and prevention of different diseases. More particularly, the application provides for the administration of CSF to the intrathecal space or the cerebral ventricles of a patient to increase intracranial pressure and/or CSF flow.

An apparatus includes an elongated body having a tapered distal end and a proximal end that are aligned along an axis; first and second electrical sensors disposed on the elongated body; an injection port on the elongated body between the first and second electrical sensors; a power source electrically coupled to the first and second electrical sensors; a computer having an input electrically coupled to the first and second electrical sensors to receive first and second output signals, respectively, from the first and second electrical sensors. The computer is configured to analyze an electrical characteristic measured by the first and second electrical sensors; and produce an output control signal when the electrical characteristic measured by the first and second electrical sensors indicates that the injection port is aligned with a target anatomical feature.

Systems and method for monitoring the glucose concentration of a patient during a peritoneal dialysis session, and automated administration of a medication in response to the glucose concentration falling outside a specified range. The system includes a peritoneal dialysis system, a glucose sensor and at least one medication infusion pump. The peritoneal dialysis system includes a control system, and a peritoneal dialysate generation flow path fluidly connectable to a patient. The glucose sensor is in communication with the control system and positioned to continuously measure the glucose concentration of the patient during the peritoneal dialysis session. The control system can be programmed to provide automated administration of medication by the at least one medication infusion pump in response to changes in the glucose concentration of the patent during the hemodialysis session.

In one embodiment, a fluid storage device includes a rigid outer housing that defines a septum cavity, a reservoir cavity, and a channel that extends between the two cavities, the outer housing further defining an outlet in fluid communication with the reservoir cavity, a septum provided within the septum cavity, the septum being made of an elastic polymer and facilitating refilling of the fluid storage device, and a thin, collapsible membrane that does not generate significant restoring forces when it is deformed as fluid is drawn from the reservoir cavity and, therefore, does not completely or partially return to its initial non-deformed shape even if the outlet of the device remains open after doses are administered.

A method of stimulation treatment for medical disorders using stimulation parameters that provide stimulation of a target site directly or create partial stimulation signals that combine into vector signals that stimulate a target site. Stimulation signals have characteristics such as frequency, timing, temporal content that is adjusted for the person being treated. Signals are designed with advantageous characteristics to influence target tissue in an intended manner and avoid producing unwanted side-effects. Stimulation signals are designed to match or avoid internal/endogenous activity (e.g., brain patterns and rhythms) of a patient. Methods for choosing, creating and partial signals are provided. Tissue modulation may be accomplished with electrical and/or magnetic stimulation, such as repetitive transcranial magnetic stimulation.

Self-righting articles, such as self-righting capsules for administration to a subject, are generally provided. In some embodiments, the self-righting article may be configured such that the article may orient itself relative to a surface (e.g., a surface of a tissue of a subject). The self-righting articles described herein may comprise one or more tissue engaging surfaces configured to engage (e.g., interface with, inject into, anchor) with a surface (e.g., a surface of a tissue of a subject). In some embodiments, the self-righting article may have a particular shape and/or distribution of density (or mass) which, for example, enables the self-righting behavior of the article. In some embodiments, the self-righting article may comprise a tissue interfacing component and/or a pharmaceutical agent (e.g., for delivery of the active pharmaceutical agent to a location internal of the subject). In some cases, upon contact of the tissue with the tissue engaging surface of the article, the self-righting article may be configured to release one or more tissue interfacing components. In some cases, the tissue interfacing component is associated with a self-actuating component. For example, the self-righting article may comprise a self-actuating component configured, upon exposure to a fluid, to release the tissue interfacing component from the self-righting article. In some cases, the tissue interfacing component may comprise and/or be associated with the pharmaceutical agent (e.g., for delivery to a location internal to a subject).

The present solution provides trans-round window membrane (RWM) drug delivery. As an overview, the system can include a micropump that is connected to a flexible cannula. The cannula can include a stiffened and sharpened tip to facilitate insertion through the RWM. The cannula can be inserted through the RWM to improve the distribution of the delivered drug throughout the inner ear. The present solution can function as a small implantable or wearable device that can be used for both chronic and acute trans-RWM drug delivery. With this configuration, the micropump can constantly or intermittently deliver, over a period of days to months, small volumes of drugs from an internal reservoir.

The present disclosure provides an apparatus including a first tubular housing including a first exit port and a second tubular housing including a second exit port. The apparatus also includes a third tubular housing coupled to at least one of the first tubular housing and the second tubular housing such that each of the first tubular housing, the second tubular housing, and the third tubular housing are fixed with respect to one another. The apparatus also includes a first catheter including a first plurality of outlets and is configured to be positioned at least partially within the first tubular housing. The apparatus also includes a second catheter including a second plurality of outlets and is configured to be positioned at least partially within of the second tubular housing. The apparatus also includes a pressure transducer line positioned in the third tubular housing and a pressure transducer coupled to the pressure transducer line.

Systems and methods for treating a cognitive disease or disorder are provided. A treatment method comprises: selecting a target volume of brain tissue to be stimulated; identifying at least one avoidance volume of brain tissue; selecting a first stimulation lead comprising at least one stimulation element; identifying at least one proposed trajectory for placement of the first stimulation lead based on the target volume and the at least one avoidance volume; placing the first stimulation lead along a placement trajectory selected from the at least one proposed trajectory; attaching the first stimulation lead to a stimulator; and stimulating the target volume with the first stimulation lead at least one stimulation element to treat at least one of a cognitive disease or a cognitive disorder. Systems include a stimulator with one or more stimulation leads and an image analyzer for identifying a proposed trajectory for placing the stimulation leads.
