Haptics and the heart: Force and tactile feedback system for cardiovascular interventions

Cardiovascular Revascularization Medicine : Including Molecular Interventions
Stuart SchecterEric Rashba

Abstract

Interventional cardiovascular procedures are performed while operators view multiple visual displays including fluoroscopic and ultrasonic images, intracardiac electrical signals, electroanatomic mapping data, and hemodynamic indices. Operators are unable to palpate physiologic and biophysical signals or feel intracardiac anatomy due to the attenuation and dampening properties of cardiac catheters. This poses a significant limitation when performing higher risk procedures such as complex coronary interventions, transeptal or epicardial puncture to gain access to the left atrium or pericardium for ablation of heart rhythm disorders, cardiac device delivery, and when attempting to maintain stable tissue contact force ("CF") during ablation of cardiac arrhythmia. We utilized signals acquired from a prototype sensorized cardiac guiding catheter, conventional transeptal puncture kit with end hole manometry, commercially available contact force sensing ablation catheter, and epicardial puncture needle, input these signals into a novel signal processing system and generated palpable sensations to blinded subjects using a proprietary tactile/force (haptic) feedback system. Qualitative and quantitative analysis of the system was perform...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
