Abstract: Intrathecal drug delivery pumps can aspirate cerebrospinal fluid (CSF) when the drug reservoir is empty or at other times to maintain a continuous or cyclic fluid flow through the pump and the delivery catheter. This addresses the potential need for continuous infusion to maintain an un-occluded fluid pathway to the intrathecal space by providing an “active port” that aspirates and expels CSF to keep fluid flow going without infusing a drug or requiring saline to fill the pump. If drug refill visits are missed, CSF could be used to keep the pump mechanism functional rather than having it run dry requiring replacement or requiring saline injections to keep the pump mechanism functioning. In addition, by having the pump aspirate CSF into the body of the pump, it would be possible to monitor biomarkers using systems in the fluid pathway and pressure differences for possible issues related to CSF management.

Abstract: In some examples, a medical system includes one or more trialing leads implanted within a patient, one or more sensors configured to determine a value for a sensed parameter indicative of an activity level of the patient, and processing circuitry. The processing circuitry may be configured to receive the value from the one or more sensors, determine whether the value is outside a threshold range, and—in response to determining that the value is outside the threshold range—generate information indicating a status of the one or more trialing leads. In some examples, processing circuitry may be configured to output an alert warning that patient movement could dislodge, or has already dislodged, the one or more trialing leads.

Abstract: A medical system, including an implantable medical device configured to administer therapy to a patient according to a programmed therapy delivery profile for treatment of a disease, disorder or condition, and a user interface configured to collect qualitative patient feedback regarding one or more symptoms related to the disease, disorder or condition, wherein the system is configured to use the collected qualitative patient feedback to personalize the programmed therapy delivery profile for improved treatment of the disease, disorder or condition.

Abstract: An extendable and retractable electrical lead for providing electrical stimulation including an elongated lead body extending from a proximal portion to a distal portion, one or more electrical contacts carried by the proximal portion of the lead body configured to be coupled to an implantable neurostimulator, one or more electrodes carried by the distal portion of the lead body configured to electrically communicate with the one or more electrical contacts to deliver neurostimulation therapy to a target treatment site based on a stimulation therapy provided by an implantable neurostimulator; and a protective sheath coaxially aligned with the lead body along a common axis and extending over part of a length of the lead body, where the protective sheath is configured to slide relative to the lead body and the common axis between an extended state and a retracted state.

Abstract: Implantable medical systems include an infusion or stimulation medical device that may be implanted and anchored within a subcutaneous or subfascial pocket by deployable anchors. The deployable anchors may be retractable. The deployable anchors may be deployed from an integral anchor system of the implanted device or from a separate chassis coupled to the implanted device. Actuators that may be controlled by a clinician may be used to deploy the anchors from a retracted state to a deployed state.
