Techniques, systems and apparatus for anchoring a therapy delivery device within a body portal are disclosed. An anchoring apparatus may comprise a first part comprising an outer sidewall and opposing grip surfaces. The outer sidewall may extend around a longitudinal axis of the apparatus to define an outer perimeter, at least a portion which may engage a surface of the body portal. A second part may comprise first and second activation members and a slot configured to receive the therapy delivery device. When the therapy delivery device is received in the slot and the second part is moved generally along the longitudinal axis, the first and second activation members may move the opposing grip surfaces toward one another to thereby anchor the therapy delivery device between the opposing grip surfaces.

A powered or automatic air management system for measuring pressure from an air pressure catheter located within a patient. Powered pumps are included in a remote pump assembly to automatically adjust the air volume to a desired level. A pressure transducer assembly is located at the bed of the patient and is connected to an air catheter, and a separate pump assembly is fixed to an IV pole away from the patient and connected to a pressure monitor to display the pressure readings. By locating the pressure transducer to a location relatively close to the connection point of the catheter, more accurate pressure readings can be achieved.

A burr cap assembly is at least partially inserted into a burr hole within the cranium of a patient. The burr cap assembly enables a elongate member to be inserted through the burr cap assembly to access a brain of the patient. A shifting member of the burr cap assembly may be configured to enable the elongate member to move with shifting fluid and matter of the brain. The shifting member of the burr cap assembly may be configured to move within a cavity defined by the burr cap assembly. The shifting member may be configured to move in a direction that is substantially perpendicular to a longitudinal axis of the distal portion of the elongate member. The shifting member may at least partially retain the elongate member, so as the shifting brain applies forces upon the elongate member, the elongate member and the shifting member may move within the cavity.

The present invention relates to a partial skull replacement consisting of polydimethylsiloxane (PDMS) and a method of monitoring biological tissues within a skull using the partial skull replacement. The method of monitoring using the partial skull replacement of the present invention has a minimal influence on intracranial pressure and cerebrospinal fluid flow as compared to a conventional cranial window technique using glass, and, by way of visualizing biological tissues within a skull with enhanced clarity, is expected to be usefully employed as a method of monitoring biological tissues within the skull.

A catheter placement device including a location portion for locating the device relative to a body part and a tubular up stand extending upwardly from the location portion and having a bore therethrough, the bore being oriented such that the bore extends angularly relative to the body part in use.

A head mounting system for therapeutic vibration is provided. The head mounting system includes first and second arms configured to support first and second movable vibration generating pads, respectively. The first and second movable vibration generating pads may be movable along tracks that are integrally formed on the inner sides of the first and second arms. The head mounting system further includes a headband dimensioned to engage a crown of a patient head. The headband includes a first end, a second end, and a power source positioned between the first end and the second end and is configured to supply vibrational power to the first and second movable vibration generating pads. The first and second arms extend laterally away from the first and second ends of the headband, respectively, and are configured to engage first and second sides of a patient face.

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.

An implantable percutaneous fluid delivery device is described that includes a subcutaneous base portion having one or more ports for supplying fluid to one or more implanted catheter devices and a percutaneous portion including an extracorporeal surface. The one or more ports of the subcutaneous base portion are accessible from the extracorporeal surface of the percutaneous portion. The subcutaneous base portion is at least partially insertable into a complementary recess formed in a bone, the subcutaneous base portion including one or more features for gripping the internal surface of such a complementary recess thereby directly anchoring the subcutaneous base portion to the bone. The device may be used to route fluid to neurosurgical catheters optionally via a router unit.

An infusion/aspiration catheter comprises an elongate catheter body, at least one infusion lumen, and an aspiration lumen extending between a proximal end and a distal end of the catheter body. The aspiration lumen terminates in a distal fluid port at the distal end of the catheter body. The catheter further comprises arms respectively having proximal ends affixed together at the distal end of catheter body. The distal fluid port of the catheter body is between the proximal ends of the arms, the arms have lumens in fluid communication with the infusion lumen(s), and each of the arms has fluid ports in fluid communication with the lumen of the respective arm. The catheter further comprises at least one infusion connector in fluid communication with the infusion lumen(s), and an aspiration connector in fluid communication with the aspiration lumen(s).
