Surface Nitriding and Oxidation of Nitinol [PDF]

, 2011
Nitinol has been widely employed in biomedical devices due to its unique mechanical properties such as superelasticity, shape memory, and good biocompatibility. However, nickel ion release from the surface of the Nitinol is an issue.

Late Extraction of Micra AV and Implantation of Right Atrial Leadless Pacemaker

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Tine‐based leadless pacemakers have been commercially implanted over the last 10 years. Retrieval of older devices is rarely discussed and based on rare case reports only. Methods A retrospective review of an extraction case of a Micra AV leadless pacemaker was performed. Internal Review Board approval was obtained.

Comparison of Two Partially Covered Metal Stents for Endoscopic Ultrasound‐guided Hepaticogastrostomy: A Multi‐Center Retrospective Study

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) is an alternative biliary drainage method after failed endoscopic retrograde cholangiopancreatography. Nevertheless, it is associated with adverse events (AEs), including peritonitis and stent migration.

Comparison Between the Acurate Neo and the Acurate Neo 2 Transcatheter Heart Valve System: Impact of Midframe Under‐Expansion

Catheterization and Cardiovascular Interventions, Volume 108, Issue 5, Page 1784-1794, November 1, 2026.
ABSTRACT Background Transcatheter aortic valve implantation (TAVI) with the Acurate Neo has been linked to a significant incidence of paravalvular leakage (PVL), addressed by the Acurate Neo 2 incorporating an active sealing skirt. Recent findings suggest that midframe under‐expansion is associated with worse outcomes.

Surface Modification of Nitinol by Biocompatible Passive Films

, 2010
Nitinol, near-equiatomic nickel-titanium alloy, exhibits unique properties, shape memory effect and superelasticity, and is therefore of a huge importance in biochemical engineering for medical devices. The high corrosion resistivity and biocompatibility
