Abstract: A medical device system is configured to guide implantation of a pacing electrode for left bundle branch pacing. The system includes a medical device having a processor configured to receive at least one cardiac electrical signal, determine a feature of the cardiac electrical signal, compare the feature to left bundle branch signal criteria, and determine a left bundle branch signal in response to the feature meeting the left bundle branch signal criteria. The system includes a display unit configured to generate a user feedback signal indicating advancement of a pacing electrode into a left portion of a ventricular septum in response to the processor determining the left bundle branch signal.

Abstract: A catheter for use in a patient's heart, especially for mapping a tubular region of the heart, has a catheter body, a deflectable intermediate section and a distal a mapping assembly that has a generally circular portion adapted to sit on or in a tubular region of the heart. A control handle of the catheter allows for single-handed manipulation of various control mechanisms that can deflect the intermediate section and contract the mapping assembly by means of a deflection control assembly and a linear control assembly. The deflection control assembly has a deflection arm and a rocker member. The linear control assembly has a linear control member, an inner rotational member and a cam. A pair of puller members are responsive to the deflection control assembly to bi-directionally deflect the intermediate section. A third puller member is responsive to the linear control assembly to contract the generally circular portion of the mapping assembly.

Abstract: There is provided an electrode catheter for measuring an electric potential inside a heart of a subject. The electrode catheter includes: a shaft that is inserted into the heart, wherein the shaft includes a distal end portion, and a guide portion that is connected to the distal end portion; a non-contact electrode that is provided on an outer circumferential surface of the distal end portion or the guide portion; and at least one contact electrode that is provided on the outer circumferential surface of the distal end portion and that is configured to make contact with an endocardium of the heart. The non-contact electrode is provided on the outer circumferential surface of the distal end portion or the guide portion so as not to make contact with the endocardium in a state where the contact electrode is in contact with the endocardium.

Abstract: In an example, a method includes receiving a cardiac signal that is sensed by an electrode at a tissue location inside the heart. Fractionations are identified in the cardiac signal. The fractionations identified at the tissue location are compared between first and second cardiac cycles of the cardiac signal. Based on the comparing, a likelihood is estimated, that the tissue location is causing a stable arrhythmia. Based on the estimated likelihood, the tissue location is indicated to a user as likely to be causing the stable arrhythmia.

Abstract: Methods, systems, computer-readable media, and apparatuses for obtaining at least one bodily function measurement are presented. A mobile device includes an outer body sized to be portable for user, a processor contained within the outer body, and a plurality of sensors physically coupled to the outer body. The sensors are configured to obtain a first measurement indicative of blood volume and a second measurement indicative of heart electrical activity in response to a user action. A blood pressure measurement is determined based on the first measurement and the second measurement. The sensors also include electrodes where a portion of a user's body positioned between the electrodes completes a circuit and a measurement to provide at least one measure of impedance associated with the user's body. A hydration level measurement is determined based on the measure of impedance.

Abstract: A catheter is described with an end effector having densely arrayed electrodes on three loops which are arrayed in various planar configurations when the end effector is unconstrained. The end effector has first, second and third loop members, each loop member includes two spines and a connector that connects the two spines to define a loop extending away from a tubular member of the catheter such that the first, second and third loop members are configured so that each connector of each of the first, second and third loop members is in contact with only one connector of the adjacent loop member.
