An implantable medical device configured to monitor fluid in proximity to an implantable medical device for an inadvertent introduction of infusate into a pocket of tissue surrounding the implantable medical device during a refill procedure, the implantable medical device including a refillable infusate delivery system, the refillable infusate delivery system including a reservoir in fluid communication with an access port, and a conductivity sensor configured to monitor fluid in proximity to the conductivity sensor for an introduction of infusate into a pocket of tissue surrounding the implantable medical device, wherein the conductivity sensor comprises a pair of electrodes positioned on an external surface of the implantable medical device.

Method to detect inadvertent delivery of drug to a subcutaneous pocket

An implantable infusate spread promoting system configured to enable improved dispersion of delivered infusate. The system including an implantable device configured to enable infusate delivery within a body of a patient, and an implantable manually actuatable flushing pump configured to remove and re-inject a quantity of fluid with each actuation to promote improved dispersion of the delivered infusate.

Fluid drug spread-promoting pump

An intrathecal drug delivery system configured to monitor one or more physiological conditions of the patient to look for opportunities to time medicament delivery to coincide with patient activity inferring heightened cerebrospinal fluid oscillations, thereby improving dispersion of the medicament within the intrathecal space of the patient. The intrathecal drug delivery system includes an implantable medical pump, one or more physiological sensors, and an external programmer configured to program the implantable medical pump with a treatment protocol specifying at least one period of time during which a specified quantity of medicament is to be administered during which the implantable medical pump utilizes data from the one or more physiological sensors to time delivery of the medicament.

Optimized intrathecal drug delivery

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.

Socketed portal anchors and methods of using same

An intrathecal drug delivery system includes: an intrathecal drug delivery device configured to deliver a fluid containing one or more pharmaceutical agents intrathecally to the cerebrospinal fluid (CSF) within a spinal canal of a patient and a deep brain catheter having an elongated body, extending from a distal end implanted within a deep brain structure of a patient and a proximal end positioned within the subarachnoid space directly adjacent to the brain to provide a passageway, via an inner lumen, between the subarachnoid space and the deep brain structure. The drug delivery system is configured to transport the pharmaceutical agent(s), using diffusion and the pulsatile flow of the CSF, through the deep brain catheter from the subarachnoid space to the deep brain structure.

Implantable medical device for delivery of pharmacological agents to the deep brain structures

A medical system configured to aid a user in locating an access port of an implantable medical device, the medical system including an implantable port comprising a medicament chamber accessible through a septum, a localizer base operably coupled to the implantable port comprising an array of electromagnetic field emitting coils, an antenna array comprising a plurality of electromagnetic field sensing coils, and a user interface adapted to display data received from the antenna array to visually depict a relative position of the antenna array relative to the localizer base.

Drug infusion port

A first medical device for obstructive sleep apnea therapy includes therapy delivery circuitry coupled to a first set of electrodes implantable proximate to a first hypoglossal nerve within a tongue of the patient and configured to deliver a first electrical stimulation signal to the first hypoglossal nerve that causes the tongue of the patient to advance and includes information to communicate to a second medical device implantable within the head or neck of the patient and coupled to a second set of electrodes implantable proximate to a second hypoglossal nerve within the tongue of the patient; and sensing circuitry coupled to the first set of electrodes and configured to receive a second electrical stimulation signal, delivered to the second hypoglossal nerve by the second medical device, that includes information that the second medical device communicates to the first medical device.

Multi-device obstructive sleep apnea (OSA) treatment

Systems and methods involve an intrathoracic cardiac stimulation device operable to provide autonomous cardiac sensing and energy delivery. The cardiac stimulation device includes a housing configured for intrathoracic placement relative to a patient's heart. A fixation arrangement of the housing is configured to affix the housing at an implant location within cardiac tissue or cardiac vasculature. An electrode arrangement supported by the housing is configured to sense cardiac activity and deliver stimulation energy to the cardiac tissue or cardiac vasculature. Energy delivery circuitry in the housing is coupled to the electrode arrangement. Detection circuitry is provided in the housing and coupled to the electrode arrangement. Communications circuitry may optionally be supported by the housing. A controller in the housing coordinates delivery of energy to the cardiac tissue or cardiac vasculature in accordance with an energy delivery protocol appropriate for the implant location.
