Objective(s): NiTi is known as the most important material for manufacturing implants and medical devises duo to its shape memory and superelasticity properties, high energy damping, and high corrosion resistance. Methods: In this project, the possibility of producing nanostructured NiTi implant with high porosity was investigated. For reaching to the nan...

INTRODUCTION Laparoscopic incisional and ventral hernia repair (LIVHR) was first reported by Le Blanc and Booth in 1993. Many studies are available in the literature that have shown that laparoscopic repair of incisional and ventral hernia is preferred over open repair because of lower recurrence rates (less than 10%), less wound morbidity, less pain, and early return to work. AIM To identify...

PURPOSE To evaluate the patency and the freedom of target lesion revascularization of the 4-French Pulsar-18 self-expandable (SE) nitinol stent for the treatment of long femoropopliteal occlusive disease in a two-center, prospective, all-comers registry with a follow-up period of 12 months. METHODS This registry enrolled 36 patients with symptomatic femoropopliteal long lesions for recanaliza...

BACKGROUND The use of ethylene-vinyl alcohol copolymer for liquid embolization of cranial vascular lesions has resulted in microcatheter fragments entrapped in patients following endovascular procedures. Undergoing subsequent diagnostic MRI examinations poses a safety concern due to the possibility of radiofrequency heating of the metallic braid incorporated into the microcatheter. Heating of n...

In this section, we provide specific information on our experimental apparatus. For all of our experiments we used a universal testing machine (Instron 5943, Norwood, MA) with a 10 N low-profile static load cell (2530 from the same manufacturer). The displacement and force resolutions were 10−4 mm and 10−4 N, respectively. Our experiments involved measuring displacements and forces of ∼ 10 mm a...

BACKGROUND Patients with endovascular stent implantation for the treatment of right ventricular outflow tract obstruction are often left with incomplete relief of the obstruction and significant pulmonary regurgitation. A noninvasive and reproducible method for monitoring such patients is desirable. MRI in the presence of a stent, however, has to overcome the problem of potential metallic artif...

T he superficial femoral artery (SFA) lies largely within the adductor canal, where it is surrounded by a double layer of fascia of the firm muscles of the thigh. After passing the adductor hiatus, the termination of the adductor canal, the SFA becomes known as the popliteal artery and enters the soft fatty tissue of the popliteal fossa. The SFA is hypothesized to undergo dramatic nonpulsatile ...

OBJECTIVE We wanted to determine the technical and clinical efficacy of using a PTFE-covered self-expandable nitinol stent for the palliative treatment of malignant biliary obstruction. MATERIALS AND METHODS Thirty-seven patients with common bile duct strictures caused by malignant disease were treated by placing a total of 37 nitinol PTFE stents. These stents were covered with PTFE with the ...

Aim of this case report was to analyze the treatment mechanics of Tip-Edge Plus appliance. A recent modification to the Tip-Edge bracket system now enables torque and tip corrections to be achieved without the use of auxiliary springs (Side-Winders). Tip Edge Plus employ nickel titanium for root uprighting by using the additional slot of the bracket. The Aesthetics and efficiency in Stage III o...

Problems of displacement, poor healing, degradation of the polymers and corrosion of the metallic frame in endovascular devices still require in-depth investigations. As the tissues and the foreign materials are in close contact, it is of paramount importance to efficiently investigate the interfaces between them. Inclusion in polymethymethacrylate (PMMA) permits us to obtain thin slides and pr...
