The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

Responsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

Periprocedural complications after laser balloon ablation procedures for atrial fibrillation: An analysis using a nationwide claims database

Heart Rhythm O2
Background: Evidence regarding the periprocedural safety of laser balloon (LB) catheter ablation for atrial fibrillation (AF) is scarce. Objective: We aimed to investigate the periprocedural safety of LB ablation for AF compared with that of either ...

Epicardial Ablation of Ventricular Tachycardia with Manual Controlled External Irrigation in a Patient with Nonischemic Cardiomyopathy

Journal of Arrhythmia, 2009
We describe a patient with nonischemic cardiomyopathy who underwent radiofrequency (RF) catheter ablation for a drug-refractory ventricular tachycardia (VT). RF ablation from a left ventricular (LV) endocardial site failed to eliminate the VT.

Comparative Effectiveness of Various Radiofrequency Ablation Catheters in the Ablation of Typical Atrial Flutter

Cardiology and Therapy, 2023
Introduction Although ablation of typical atrial flutter (AFL) can be easily achieved with radiofrequency energy (RF), no studies compare the effectiveness of different ablation catheters.

Radiofrequency catheter ablation of supraventricular tachycardia.

Indian pacing and electrophysiology journal, 2002
Supraventricular tachycardias are quite common in clinical practice. Medical treatment of supraventricular tachycardia often involves regular intake of drugs for several years. Problems of drug therapy include poor efficacy and bothersome side effects including proarrhythmia. This has lead to the development of non-pharmacological therapies. Arrhythmia

Influence of Radiofrequency Catheter Ablation on Platelet Aggregation [PDF]

Clinical and Applied Thrombosis/Hemostasis, 2007
the objective of this article was to find out how radiofrequency catheter ablation (RFA) influences platelet aggregation (PA), and the dependence on the total energy (TE) of RFA used and the cause of arrhythmia. We investigated 97 patients. PA was analyzed before, after, and in 24 hours after RFA.

Mapping the lineage of prostate tissue ablation medical device predicates for focal therapy of prostate cancer approved via the FDA 510(k) clearance pathway

Surgical Practice, EarlyView.
Abstract Objective Medical devices are reviewed by the US Food and Drug Administration (FDA) for safety and effectiveness. Class II devices can receive 510(k) clearance if they are “substantially equivalent” to an existing predicate device. This process can be repeated iteratively, leading to a lineage of predicates for newly cleared devices.
