An electrode device for implantation in a subject, said electrode device comprising: a control unit arranged in a biocompatible package configured to protect the control unit from an implant environment; an electrode arrangement comprising electrodes for providing electrical signals to and/or acquiring electrical signals from a body part of the subject; a plurality of electrode leads, each configured to connect the control unit with a respective electrode and each being fixedly connected to the control unit; and an interface wire configured to connect the control unit to a powering device, wherein the interface wire is configured to provide power from the powering device to the control unit and communication between the control unit and the powering device. An implantable system comprises the electrode device and the powering device.

A catheter has a distal assembly with at least one loop with ring electrodes. A single continuous puller wire for bidirectional deflection is pre-bent into two long portions and a U-shape bend therebetween. The U-shape bend is anchored at a distal end of a deflectable section which is reinforced by at least one washer having at least two holes, each hole axially aligned with a respective lumen in the deflectable section. Each hole is centered with a lumen so that each puller wire portion therethrough is straight and subjected to tensile force only. A proximal end of the support member is flattened and serrated to provide a better bonding to the distal end of the deflectable section.

A diagnostic electrocardiogram (ECG) apparatus (20) is disclosed herein. The apparatus comprises a body and printed electrodes. The body (110) includes extension members (61-66), with each having an expansion section (61a) and at least one electrode section (61b). Each expansion section (61a) has at least one concertina member (75) and at least one connector member (76). The diagnostic ECG apparatus (20) conforms to American Heart Association guidelines on diagnostic resting ECGs.

In some embodiments, an apparatus comprises a biocompatible substrate configured to be disposed on a surface of a brain and including a plurality of nodes and a plurality of connectors interconnecting the plurality of nodes, the biocompatible substrate defining a plurality of openings therein, each of the plurality of nodes and the plurality of connectors including at least one encapsulation material.

An example method is performed by an electrocardiogram (ECG) device and includes determining a number of lead wires of an ECG cable assembly that is attached to the ECG device. The method also includes receiving ECG signals using electrodes of the ECG cable assembly. Further, the method includes using the number of lead wires as a basis for selecting a live-lead view from among a first live-lead view and a second live-lead view. Still further, the method includes displaying a representation of the ECG signals in the selected live-lead view in accordance with the selection.
