Abstract: A medical device having an elongate body with a proximal portion, a distal portion, and defining a lumen therethrough. The medical device has an expandable element coupled to the distal portion of the elongate body, the expandable element defining a proximal portion, a distal portion opposite the proximal portion and an intermediate portion disposed between the proximal portion and the distal portion. The expandable element also has an inner surface and an outer surface opposite the inner surface. The medical device has a plurality of cutting members, each cutting member being coupled with the outer surface of the expandable element, each cutting member having a proximal end and a distal end opposite the proximal end, the proximal end being proximate the proximal portion of the expandable element and the distal end being proximate to the intermediate portion of the expandable element.

Abstract: A pacemaker has a housing and a therapy delivery circuit enclosed by the housing for generating pacing pulses for delivery to a patient's heart. An electrically insulative distal member is coupled directly to the housing and at least one non-tissue piercing cathode electrode is coupled directly to the insulative distal member. A tissue piercing electrode extends away from the housing.

Abstract: A medical device includes a motion sensor for producing a motion signal including cardiac event signals. The medical device generates a ventricular pacing pulse upon expiration of a pacing interval. The medical device determines a synchrony metric from the motion signal after a delivered ventricular pacing pulse and adjusts the pacing interval based on the synchrony metric.

Abstract: A surgical method treats infections on a lead positioned at least partially within a patient's body. The surgical method includes uncoupling the lead from a pulse generator. The lead is then coupled to an ultrasound wave generator. Ultrasound waves are propagated from the ultrasound wave generator through the lead. Systems are disclosed.

Abstract: A method of creating a shunt between a right atrium and a left atrium of a mammalian heart including puncturing an atrial septum between the right atrium and the left atrium to create a shunt. An ablation device having balloon is advanced at least partially through the shunt. The balloon is inflated and configured to thermally isolate the atrial septum from blood within the left atrium and the right atrium. Ablation energy is delivered to ablate the atrial septum.

Abstract: An implantable lead system may include an adjustable lead assembly. The lead assembly may include a fixation member and an implantable lead slidably coupled to and rotatable relative to the fixation member. The implantable lead system may include a telescoping delivery system. The delivery system may include an outer catheter and an inner catheter slidably coupled to and rotatable relative to the outer catheter. The lead assembly may be implanted in a cardiac septal wall through the delivery assembly.

Abstract: A reservoir of a system for deploying an implantable lead to an extravascular location delivers a flow of fluid through a lumen of one or both of a tunneling tool and an introducer of the system. In some cases, the tunneling tool includes a pressure sensor assembly for monitoring a change in a pressure of the flow through the lumen thereof. Alternately, or in addition, a flow-controlled passageway, through which the flow of fluid from the reservoir is delivered to the lumen of the introducer, includes a compliant chamber to hold a reserve of the fluid. Fluid from the reserve may be drawn into the lumen of the introducer as the tunneling tool is withdrawn therefrom. Alternately, the introducer may include a chamber located between two seals, wherein fluid that fills the chamber is drawn distally into the lumen of the introducer, as the tunneling tool is withdrawn therefrom.

Abstract: VfA cardiac therapy uses an implantable medical device or system. The implantable medical device includes a tissue-piercing electrode implanted in the basal and/or septal region of the left ventricular myocardium of the patient's heart from the triangle of Koch region of the right atrium through the right atrial endocardium and central fibrous body. The device may include a right atrial electrode, a right atrial motion detector, or both. The device may be implanted completely within the patient's heart or may use one or more leads to implant electrodes in the patient's heart. The device may be used to provide cardiac therapy, including single or multiple chamber pacing, atrioventricular synchronous pacing, asynchronous pacing, triggered pacing, cardiac resynchronization pacing, or tachycardia-related therapy. A separate medical device may be used to provide some functionality for cardiac therapy, such as sensing, pacing, or shock therapy.

Abstract: A system and method of positioning an atrial pacing lead for delivery of a cardiac pacing therapy that includes sensing electrical activity of tissue of a patient from a plurality of external electrodes and determining a distribution of bi-atrial activation in response to the sensed electrical activity. A target site for delivering the atrial pacing therapy is adjusted based on a change in bi-atrial dyssynchrony that is determined in response to the determined distribution of bi-atrial activation, and placement of the atrial pacing lead for delivery of the atrial pacing therapy is determined in response to the adjusting.

Abstract: Cardiac electrical heterogeneity information may be used to determine whether one or more His bundle paced settings for His bundle pacing therapy are acceptable for His bundle pacing. Cardiac electrical heterogeneity information may be generated during His bundle pacing, and the evaluation against baseline information and/or other information to determine whether the His bundle paced settings are acceptable.
