Abstract: Systems, methods, devices and computer software for delivering electrical stimulation to biological tissue are described. In some implementations, an electrical lead for implantation in a patient can include a distal portion with electrodes that are configured to generate therapeutic energy for biological tissue of the patient, such as the heart or pericardium. The distal portion can include an electrode extension having a tip electrode, the electrode extension configured to facilitate contact of the tip electrode with biological tissue of the patient when the lead is in a deployed configuration. A distal part of the lead can be configured to include a heel portion, a bend in a proximal part, and/or a bend in a distal part, to facilitate contact of an electrode located on the heel portion with biological tissue of the patient when the lead is in a deployed configuration.

Abstract: A therapy specific, pre-programmed, hand-held auto-injection device for delivering a drug to a patient includes a housing, a plurality of syringes carried by the housing, at least one actuator disposed within the housing coupled to the plurality of syringes, and a controller disposed within the housing and communicatively coupled to the at least one actuator.

The controller is also configured to operate the at least one actuator based on the infusion and aspiration protocol by either expelling a fluid from a respective barrel of the plurality of syringes into the infusion and aspiration location or drawing a fluid from the infusion and aspiration location into a respectively barrel of the plurality of syringes.

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: Fluid delivery systems and methods of delivering an agent and treating a disorder are disclosed that include a subcutaneously implantable port having a body defining a chamber with an open top and a delivery opening and a septum coupled to the body to extend over the open top of the chamber. The systems and methods can further include an intrathecal catheter having an proximal end configured to be coupled to the port and fluidly coupled to the delivery opening of the chamber and a plug having a body with a passage to receive the intrathecal catheter therethrough. The plug can be configured to be inserted into the fascia to protect against leakage of cerebrospinal fluid.

Abstract: A method of delivering a drug to a patient using a therapy specific, pre-programmed auto-injection device includes positioning the hand-held device proximate to an infusion and aspiration location of the patient, and receiving, at a controller disposed within the housing, an infusion and aspiration profile. The infusion and aspiration profile including an infusion and aspiration protocol for controlling at least one of a plurality of syringes partially disposed within the housing. The method also includes operating at least one actuator coupled to the plurality of syringes according to the infusion and aspiration protocol, causing the syringes to expel a fluid from a respective barrel of the plurality of syringe into the infusion and aspiration location or causing the syringes to draw a fluid from the infusion and aspiration location into a respective barrel of the plurality of syringes.

Abstract: Fluid delivery systems and methods of delivering a therapeutic agent are disclosed that include a subcutaneously implantable port that can be easily and efficiently located through the tissue of a patient. The port includes a body that defines a chamber having an open top, a delivery opening, and a catheter connection portion, and a septum disposed on the body, where the septum includes a lower surface extending over the open top of the chamber and an opposite, upper surface. The port further includes a cap of the port that defines an opening extending therethrough and the cap is configured to be coupled to the body to secure the septum within the port with the opening of the cap providing needle access to the septum. The cap includes a downwardly tapered surface that extends around the opening and is configured to direct a needle towards the upper surface of the septum.
