Invasive Intervention

Emerging paradigms furthering the reach of medical technology into human anatomy present unique modeling, control, and sensing problems. This review provides a brief history of medical robotics, leading to the current trend of minimally invasive intervention and diagnostics in confined spaces. We discuss robotics for natural orifice and single-port access surgery, capsule and magnetically actuated robotics, and microrobotics, with the aim of elucidating the state of the art. We also discuss works on modeling, sensing, and control of mechanical architectures of robots for natural orifice and single-port access surgery, followed by works on magnetic actuation, sensing, and localization for capsule robotics and microrobotics. Finally, we present challenges and open problems in each of these areas.

Access Surgery

Objective The placement of epicardial pacing wires before weaning from bypass during port-access heart surgery can be difficult or impossible. Sometimes, it is necessary to pacing the patient to wean from bypass, and it is problematic to exchange the Edwards pulmonary vent (EndoVent) for a pace catheter under the drapes. Our objective was to devise an effective means of pacing the patient using the pulmonary vent catheter. Methods All patients having aortic valve minimally invasive port-access surgery have a pacing wire deployed through the Edwards EndoVent catheter. We did a retrospective chart analysis of these cases. Results After reviewing the anesthesia records, we determined that we were able to reliably convert the pulmonary vent catheter, which is beneficial for the surgery, into a pacing catheter before weaning from bypass 100% of the time. The mean pacing threshold current was 1.60 mA with the wire in the right ventricular apex. Conclusions We found that in all 25 patients we were able to rapidly convert the vent catheter into a reliable pacing catheter without any complications.

Specific Tissue

William Harvey was the first scientist to describe the heart as consisting of separate right- and left-sided circulations. Our understanding of the heart’s anatomy and physiology has grown significantly since this landmark discovery in 1628. Today, we recognise not only the importance of these separate systems, but also the specific tissue that divides them. Our growing understanding of the inter-atrial septum has allowed us to identify defects within this structure and develop effective percutaneous devices for closure of these defects in the adult patient. This article discusses the formation of a patent foramen ovale (PFO) and atrial septal defect (ASD). In addition, we describe the medical illnesses caused by these defects and summarise the indications and risks related to percutaneous closure of these defects. We also report the most up-to-date transcatheter therapeutic options for closure of these common congenital defects in the adult patient.

Cerebrovascular Events

Innovative percutaneous procedures for stroke prevention have emerged in the last two decades. Transcatheter closure of the patent foramen ovale (PFO) is performed in patients who suffered a cryptogenic stroke or a transient ischaemic attach (TIA) in order to prevent recurrence of thromboembolic events. Percutaneous occlusion of the left atrial appendage (LAA) has been introduced to reduce stroke risk in patients with atrial fibrillation (AF). The role of PFO and LAA in the occurrence of cerebrovascular events and the interventional device-based therapies to occlude the PFO and LAA are discussed.
