Epicardial Electrodes TRIZ Cases

Pre-excitation pacing therapy delivers timed electrical pulses to myocardial sites near an infarct to synchronize ventricular contraction.

Merging drive-sense circuits onto one line eliminates separate wiring, reducing power consumption while maintaining reliable bidirectional data communication.

Hinged lead design reduces mechanical stress on myocardial tissue during cardiac motion, enabling minimally invasive implantation and reliable long-term pacing.

An implantable device adapts pacing parameters based on real-time cardiac feedback to improve diastolic function in HFpEF patients.

A subcutaneously implantable cardiac device uses a clip to anchor the housing to tissue while prongs extend to contact the heart for sensing and therapy.

Coaxial suction feet stabilize epicardial tissue, enabling precise lead placement without complex venous navigation.

A leadless pacemaker identifies atrial events using ventricular filling artifacts detected by motion sensors.

Navigating a guidewire through the transverse sinus and capturing it with a snare stabilizes epicardial devices while preventing coronary artery puncture.

A spring-biased tethering cap shifts between closed and open configurations to guide catheters through tight cardiac spaces.

Combining a piercing tip with a conductive helix resolves the trade-off between complex fixation mechanisms and reliable tissue contact.

Segmented intra-pericardial leads eliminate MRI-induced RF heating by placing telemetry coils outside the myocardium while maintaining precise pacing access.
