Anchors for securing a medical device relative to a body portal, wherein the anchors may accommodate most any implantation trajectory through the portal. Such anchors may further secure the device along any such trajectory without imparting undesirable biasing forces that may shift the device from its intended implanted location. In some embodiments, the anchor is configured as a burr hole anchor including a spherical member contained in a socket of the anchor such that orientation of the spherical member is permitted about three mutually perpendicular axes.

An intraosseous access system can include a hub coupled to a cannula that can be introduced into a bone of a patient. The system further includes a securement device that can couple with the hub when transitioned from an open orientation to a closed orientation. The securement device includes a first segment and a second segment that are spaced apart from each other when the securement device is in the open orientation and are approximated and secured to each other when the securement device is in the closed orientation. The first segment includes a first receptacle that receives a portion of the hub therein and contacts the hub to restrain movement of the hub relative to the securement device when the securement device is coupled with the hub in the closed orientation. The first segment also includes a first arm coupled to the first receptacle, the first arm biasing the first receptacle toward the hub when the securement device is coupled with the hub in the closed orientation.

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.

An intraosseous access device can include a device body, a trocar needle, and an intraosseous catheter removably disposed on the trocar needle. The device body can be configured to enable a user of the access device to manually insert a distal tip of the trocar needle through a skin surface of a body of a patient to an external surface of a bone of the patient. The intraosseous access device can include a first advancement member configured to provide a first distal advancement force sufficient to distally advance a distal tip of the trocar needle and the catheter through a skin surface to an external surface of a bone of a patient, and a second advancement member configured to provide a second distal advancement force sufficient to distally advance the distal tip of the trocar needle and the catheter through the external surface of the bone.

An intracranial prosthesis comprised of a flat body having an interior ultrasound-compatible window and means about the outer portion capable of engaging a plurality of diagnostic instruments and/or intracranial delivery systems so that a practicing medical professional can monitor certain parameters of a patient or deliver therapeutic agents to the patient while using an ultrasound-monitoring device to image the patient's brain. The prosthesis is designed to allow for the continuous, uninterrupted, simultaneous monitoring of a number of parameters of a patient's brain at the patient's bedside.

A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either within the brain. Once positioned at a desired location, the obturator is removed, leaving a distal end of the outer sheath adjacent an area of interest, and creating a working corridor. Interrogation of the area of interest may be performed to evaluate a disorder and/or abnormality, as well as evaluate treatment regimes. Interventional devices may also be introduced to the area of interest, as well as a variety of treatments.

A lubrication device for lubricating a joint of a human or mammal patient, which is entirely implantable in a patient's body, comprises a reservoir for storing a lubricating fluid and a fluid connection for introducing the lubricating fluid into the joint when the device is implanted in the patient's body. Further, the fluid connection comprises a fluid connection device connecting the reservoir with the joint such that a lubricating fluid flow is established from the reservoir into the joint. The fluid connection comprises either an infusion needle adapted to be intermittently placed into the joint for injecting the lubricating fluid, or a tube adapted to be permanently placed into the joint for continuously injecting the lubricating fluid.

An access device configured for inserting an intraosseous catheter into an interior portion of a bone is disclosed. In one embodiment, an intraosseous access device is disclosed, comprising a device body, a trocar needle included with the device body, and an intraosseous catheter removably disposed on the trocar needle. The device body is configured to enable a user of the access device to manually insert a distal tip of the trocar needle through a skin surface of a body of a patient to an external surface of a bone of the patient. An advancement mechanism is also disclosed and is configured to selectively and distally advance the trocar needle and intraosseous catheter a predetermined distance into an internal portion of the bone of the patient after the distal tip of the trocar needle has been inserted to the external surface of the bone.

Apparatus for delivering therapeutic agents to the central nervous system of a subject is described. The apparatus includes at least one intracranial catheter and a percutaneous access device. The percutaneous access device includes a body having at least one extracorporeal surface and at least one subcutaneous surface, the body defining at least one port for connection to an implanted intracranial catheter. The port is accessible from the extracorporeal surface of the device, but is provided with a seal such as a rubber bung between the lumen of the port and the extracorporeal surface. The percutaneous access device may have more than two ports and/or a flange. A method of implanting the percutaneous access device is also described.

An intracranial prosthesis comprised of a relatively flat, ultrasound-compatible body capable of engaging a plurality of diagnostic instruments and/or intracranial delivery systems so that a practicing medical professional can monitor certain parameters of a patient or deliver therapeutic agents to the patient while using an ultrasound-monitoring device to image the patient's brain. The prosthesis is designed to allow for the continuous, uninterrupted, simultaneous monitoring of a number of parameters of a patient's brain at the patient's bedside.
