A system for application of neurostimulation includes an outer sheath, an elongate inner member in the outer sheath and movable relative to the outer sheath. The inner lumen has a distal end. An expandable member is coupled to the distal end of the inner member and is in the outer sheath. The expandable member is self-expanding upon from a compressed state in the outer sheath to an expanded state out of the outer sheath. The expandable member includes a distal portion including a plurality of wires woven together and a proximal portion including the plurality of wires extending parallel to a longitudinal axis. The system includes a plurality of electrode assemblies outward of the expandable member and circumferentially spaced around the expandable member. Each electrode assembly is coupled to two of the wires extending parallel to the longitudinal axis. Each electrode assembly includes a plurality of longitudinally-spaced electrodes.

A method of right atrial pacing of a heart of a patient includes the steps of: stimulating right atrial tissue of the heart using a right atrial lead of a dual chamber cardiac pacemaker to pace the heart with a stimulus architecture protocol; and stimulating local sympathetic and/or parasympathetic tissues with the stimulus architecture protocol proximate to the paced right atrial tissue causing nervous system activity that inhibits the autonomous nervous system to reduce blood pressure. A closed loop system operating according to this method and a cardiac pacing lead for implementing this method also are included within the scope of the illustrated embodiments.

An implantable wireless sensor is provided for determining a pressure of a lumen in a body. The sensor comprises a sensor body comprising a plurality of substrates, at least a portion of the substrates comprising a first dielectric material. An LC resonant circuit is contained with the sensor body. A capacitance of the LC resonant circuit is configured to vary in response to changes in pressure in the lumen. A first anchoring element is coupled to a proximal end of the sensor body and a second anchoring element is coupled to a distal end of the sensor body. The first and second anchoring elements are configured to lodge the sensor body within the lumen. A second dielectric material, different than the first dielectric material, is provided over at least a portion of at least one of the plurality of substrates.

There is provided a method for treating a male impotent patient comprising stimulating at least one portion of the patient's normal penile tissue or the prolongation thereof to at least restrict the blood flow leaving the penis to achieve erection. To improve the erection effect the method further comprises gently constricting the penile portion or the prolongation thereof to restrict the venous blood flow in the penile portion, and then stimulating the constricted penile portion to cause contraction of the penile portion to at least further restrict the blood flow leaving the penis to achieve erection.

In some examples, controlling delivery of CRT includes delivering ventricular pacing according to a sequence of different values of at least one of A-V delay or V-V delay, and acquiring one or more electrograms from respective vectors. For each of the different values of the at least one of A-V delay or V-V delay, at least one of a QRS amplitude or a QRS area may be determined based on the one or more electrograms, and a target change in QRS amplitude or QRS area between adjacent ones of the values of the at least one of A-V delay or V-V delay of the sequence may be identified. In response to the identification of the target change, the implantable medical device may deliver the ventricular pacing at a value of the at least one of A-V delay or V-V delay determined based on the identification to provide CRT.

The present invention relates to an implantable device for stimulating a heart and lowering blood pressure, comprising: a stimulation unit configured to stimulate the His bundle or the left-bundle branch of the heart, and a sensing unit for detecting atrial activity of the heart. According to the present invention the stimulation unit is configured to stimulate the His bundle or the left bundle branch immediately before or immediately after detection of an atrial activity.

A method for treating a male impotent patient, the method comprising the steps of cutting the skin of the patient, inserting a dissecting tool and dissecting an area of at least one portion of a tissue wall of a penile portion, and placing a medical device. The medical device comprises a constriction device configured to gently constrict the penile portion to restrict the blood flow leaving the penis, and a stimulation device configured to stimulate the penile portion constricted by the constriction device to at least further restrict the blood flow leaving the penis to achieve erection.

A leadless cardiac pacemaker (LCP) may be deployed within a patient's vasculature at a location near the patient's heart in order to pace the patient's heart and/or to sense electrical activity within the patient's heart. In some cases, an LCP may be implanted within the patient's superior vena cava or inferior vena cava. The LCP may include an expandable anchoring mechanism configured to secure the LCP in place.
