Abstract: The fluid delivery devices, systems and methods described herein include a subcutaneous port, a catheter, and a connection assembly configured to fluidly couple the port and catheter.

Abstract: Fixation devices are disclosed herein that can be used to secure to a catheter. The fixation devices include a body having a central bore extending therethrough to receive a catheter and at least one end having a tapered profile tapering inwardly a distal edge thereof. The body can include an expanded intermediate portion, such as one or more bulbous portions. The fixation devices can also include suture openings or grooves to secure the devices to tissue.

Abstract: Drug delivery systems and methods are disclosed herein. In some embodiments, a drug delivery system can be configured to deliver a drug to a patient in coordination with a physiological parameter of the patient (e.g., the patient’s natural cerebrospinal fluid (CSF) pulsation or the patient’s heart or respiration rate). In some embodiments, a drug delivery system can be configured to use a combination of infusion and aspiration to control delivery of a drug to a patient. Catheters, controllers, and other components for use in the above systems are also disclosed, as are various methods of using such systems.

Abstract: Fixation devices are disclosed herein that can be used to secure to a catheter and to tissue. The fixation devices include a body having a bore extending therethrough to receive a catheter. The fixation devices can also include suture openings or grooves to secure the devices to tissue.

Abstract: Systems and methods for delivering a drug or other therapy over an extended period of time (e.g., several hours, days, weeks, months, years, and so forth) are disclosed herein, as are systems and methods for monitoring various parameters associated with the treatment of a patient. Systems and methods are also disclosed herein that generally involve CED devices with various features for reducing or preventing backflow.

Abstract: 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.

Abstract: Automated drug delivery systems and related methods are disclosed herein. In some embodiments, these systems can reduce or eliminate infusion inconsistencies. An exemplary system can include a syringe actuator which can be controlled via electrical, mechanical, pneumatic, and/or hydraulic means to precisely infuse and/or withdraw material from a patient.

Abstract: Systems and methods are provided herein that generally involve shunting fluid, e.g., shunting cerebrospinal fluid in the treatment of hydrocephalus. Self-cleaning catheters are provided which include split tips configured such that pulsatile flow of fluid in a cavity in which the catheter is inserted can cause the tips to strike one another and thereby clear obstructions. Catheters with built-in flow indicators are also provided. Exemplary flow indicators include projections that extend radially inward from the interior surface of the catheter and which include imageable portions (e.g., portions which are visible under magnetic resonance imaging (MRI)). Movement of the flow indicators caused by fluid flowing through the catheter can be detected using MRI, thereby providing a reliable indication as to whether the catheter is partially or completely blocked.

Abstract: A tongue manipulation device (10) has a tissue anchor (20) for attachment to the tongue, a bone anchor (22) typically for attachment to the mandible and a tether line (24) which fixes the tissue anchor to the bone anchor. The bone anchor comprises a tether line spool arrangement which comprises a spool (46) rotatable about a spooling axis and a spooling locking arrangement (54). The spooling locking arrangement is controlled by rotation about the spooling axis between spooling locking and permitting configurations. In this way, the physician implanting and setting the device can perform titration and subsequent locking as two independent operations.

Abstract: Percutaneous therapy or drug delivery devices are described herein. The device can include one or multiple lumens inside a cannula or catheter body. The device can include features for reducing or preventing backflow or reflux of infusate along the device insertion track, such as one or more bullet noses, over tubes, and/or micro-tips. The device can be used in any of a variety of treatment methods, including to inject cancer therapy medicinal products directly into pulmonary tumors or tumors located in other regions of the body. The device can include features to keep the distal tip secure during patient respiration or during other patient movement, and can reduce the incidence of reflux during therapy delivery.
