INTRODUCTION One of the most difficult and time-consuming steps in malleostapedotomy surgery is the crimping of the prosthesis onto the malleus handle manually. The advent of the nitinol prosthesis (Gyrus nitinol piston [GNP]; Gyrus ENT LLC, Bartlett, TN) significantly reduced the difficulty of this surgical step, rendering its fixation to the malleus easy and fast. However, Kwok et al. analyze...

Objective. To visually compare the Nitinol "smart" stapes prosthesis to conventional manual crimping stapes pistons in temporal bone cadaver specimens. Main Outcome Measures. 10 otolaryngologists were given a photograph of the randomly ordered stapes pistons and asked to use the pictures to answer questions about each stapes piston. The answers to the survey were then recorded for analysis. Res...

BACKGROUND AND OBJECTIVE To determine whether the NiTiNol frame of a novel hernia repair device utilizing polypropylene mesh for inguinal hernioplasty remains stable and intransient without fixation after a minimum of 6 months. METHODS Twenty patients had 27 inguinal hernias repaired using a novel hernia repair device that has a NiTiNol frame without any fixation. Initial single-view, postope...

BACKGROUND Stenting has been shown to improve patency after femoral artery revascularization compared with balloon angioplasty. Limited data are available evaluating endovascular treatment for obstructive lesions of the popliteal artery. METHODS AND RESULTS This prospective, randomized, multicenter trial compared primary nitinol stent placement to percutaneous transluminal balloon angioplasty...

BACKGROUND A new penetrating stapled anastomotic system using nitinol microclips (Coalescent Surgical U-Clip) has been developed to facilitate the construction of compliant interrupted sutures for minimally invasive and robotic surgery as well as for conventional procedures. The purpose of this study was to determine the effect of nitinol U-Clips used for coronary anastomosis in the development...

OBJECTIVE To compare the hearing results in patients with otosclerosis who underwent a stapedotomy with either a platinum wire prosthesis or a commercially available, heat-activated nitinol stapes piston prosthesis. DESIGN Retrospective medical chart review. SETTING Academic tertiary care medical center. PATIENTS Seventy-nine consecutive patients diagnosed as having otosclerosis who under...

BACKGROUND Self-expanding metal and plastic esophageal stents (SEMS and SEPS, respectively) are used in conjunction with chemoradiation for palliation of malignant dysphagia. To date, the dosimetric effects of stents undergoing proton radiotherapy are not known. STUDY AIM To investigate the proton radiotherapy dose perturbations caused by esophageal stents of varying designs and materials und...

Additive manufacturing (AM) of customised vascular or peripheral stents is great potential for surgeons and patients, enabling the patients to have achieving better outcomes from stenting procedures, with further advantages having a resource efficient process. In this study, AM superelastic NiTi-based shape memory alloy (Nitinol) was investigated. Two stent designs, which are used treatment com...
