Patent number: 10639478Abstract: Neuromodulation is used to enhance left ventricular relaxation. An exemplary neuromodulation system includes a therapy element positionable in proximity to at least one nerve fiber, and a stimulator configured to energize the therapy element to delivery therapy to the at least one nerve fiber such that left ventricular relaxation and left ventricular contractility are contemporaneously enhanced.Type: GrantFiled: January 31, 2018Date of Patent: May 5, 2020Assignee: NeuroTronik IP Holding (Jersey) LimitedInventors: Michael Cuchiara, Stephen C Masson

Patent number: 10524832Abstract: A method for positioning an electrode array of a neuromodulation catheter at a target circumferential position along a posterior wall of a superior vena cava includes advancing the catheter to a target longitudinal position within the superior vena cava, and orienting a marker on the extracorporeal portion of the catheter in a circumferential orientation known to position the array at the target circumferential position along the posterior wall. A method of positioning the array at a target longitudinal position includes advancing the catheter into the superior vena cava and using features of the catheter to detect the location of right atrial tissue, such as by sensing for a P-wave using an electrogram captured using an electrode carried at a distal end of the catheter, or by using such electrodes to capture the atrium using atrial pacing pulses. Once the location of the right atria is determined, the electrode array may be deployed in a position known to be proximal to the atrium.Type: GrantFiled: October 30, 2017Date of Patent: January 7, 2020Assignee: NeuroTronik IP Holding (Jersey) LimitedInventor: Stephen C Masson

Publication number: 20180236220Abstract: An intravascular catheter is positionable within a blood vessel for use in transvenous stimulation of targets external to the wall of the blood vessel. The catheter includes a catheter body, a support at the distal end of the catheter body, and a plurality of electrodes carried by the support. At least a portion of the support being inflatable within the blood vessel to bias at least a portion of the plurality of electrodes into contact with the blood vessel wall.Type: ApplicationFiled: April 19, 2018Publication date: August 23, 2018Applicant: NeuroTronik IP Holding (Jersey) LimitedInventors: Richard A.

Publication number: 20140316496Abstract: A neuromodulation catheter positionable within a blood vessel for transvascular nerve stimulation includes a catheter body and an electrically insulative substrate carried at a distal end of the catheter body. A distal end of the substrate includes a plurality of laterally spaced-apart fingers. The substrate includes a first face and a second face on an opposite side of the substrate from the first face. A plurality of electrodes are disposed on the first face of the substrate such that each of the fingers has a plurality of the electrodes longitudinally spaced thereon. A support at the distal end of the catheter is expandable within the blood vessel to bias the first faces of the fingers against the wall of a blood vessel so as to bias at least a portion of the electrodes in contact with the wall.Type: ApplicationFiled: November 20, 2013Publication date: October 23, 2014Applicant: NeuroTronik IP Holding (Jersey) LimitedInventors: Stephen C.
