Abstract:

When fabricating a small diameter arterial prosthesis, the performance requirements include controlling dimensions, maintaining a uniform structure, ensuring superior mechanical properties as well as excellent biocompatibility. Material selection and fabricating methods can influence these factors. In this study, three 100% polyester prostheses, three bicomponent polyester/silk prostheses and three 100% silk prostheses were woven into seamless tubular prototype prostheses with three different basic weaves. After degumming/scouring they met the target inner diameter of 3.83 ± 0.30 mm which demo

Abstract:

In the market for products for the needs of cardiovascular surgery, there is still no effective vascular prosthesis with a diameter of less than 4 mm, despite the continuous increase in the incidence of atherosclerosis and the increase in the number of surgical operations to restore blood flow in the affected arteries. At the same time, vascular tissue engineering has diverse methodological approaches for the development of effective functionally active small-diameter vascular prostheses suitable for adaptive growth and regeneration in situ.

Oral rehabilitation with fully ceramic implant-supported prostheses is one of the treatment options that presents clinical longevity and patient satisfaction. However, complications regarding the chipping are reported in the literature. To reduce these problems, the use of monolithic zirconia is constantly suggested. Another option, not so reported, are the modifications in the final configuration of the cover ceramic. The design of the chosen materials is discussed.

Then, the decellularized pericardium was employed for a primary cover of a transmural left ventricular defect in minipigs (n = 9).

Background/Objectives: Surgical removal is the treatment of choice for cholesteatoma control.

Titanium foreign materials (prostheses, meshes) can be used to restore sound transmission and to cover larger defects of the skull base. After the operation, recurrence and residual control are necessary. This can be achieved by means of second-look surgery or an MRI examination with a non-EPI DWI sequence.

Several studies have shown that 65 % of expanded poly (tetrafluoroethylene) (ePTFE) vascular prostheses had to be explanted within 10 years of implantation in humans.

It has been shown that surface modification of ePTFE arterial prostheses could enable their endothelialization therefore improving their biocompatibility and hemocompatibility. Indeed, endothelial cells naturally cover the biological blood vessel wall and consequently, an endothelial layer constitutes the best achi

Abstract:

A tactile glove sensory system of the haptic feedback stimulation system for the upper limb prostheses was developed in this work to enable the patients of the upper limb amputation to recover the sense of touch and slippage. The system features six of a spot piezoresistive force sensors of type Quantum tunnelling compositesÂ (QTC) with 10 mm diameter, in order to measure the contact pressure between the hand and the objects. Five sensors were distributed on each fingertip and an extra sensor was mounted on the handâ€™s palm to cover all the critical point and increase the probability of detec

Abstract:

Falls and fear of falling are significant problems arising from impaired balancing abilities that affect people with lower limb amputation during unassisted transfer manoeuvres and ambulation. It is important to develop and evaluate efficient therapeutic interventions aimed at improving balancing and coordination skills. A group of 14 persons after trans-tibial amputation, fitted with trans-tibial prostheses, were included in a balance-training programme, consisting of approximately 20 minutes of balance training per day for five consecutive days on BalanceReTrainer – a novel balance-training,

Abstract:

Clinically used heart valve prostheses, despite their progress, are still associated with limitations. Biodegradable poly-ε-caprolactone (PCL) nanofiber scaffolds, as a matrix, were seeded with human endothelial colony-forming cells (ECFCs) and human induced-pluripotent stem cells-derived MSCs (iMSCs) for the generation of tissue-engineered heart valves. Cell adhesion, proliferation, and distribution, as well as the effects of coating PCL nanofibers, were analyzed by fluorescence microscopy and SEM. Mechanical properties of seeded PCL scaffolds were investigated under uniaxial loading. iPSCs w

Purpose: To investigate the extent to which clinical status is affected by covering the left subclavian artery (LSA) with stent-grafts in the thoracic aorta. Methods: Stent-graft reconstruction of the thoracic aorta was performed in 23 patients (20 men; mean age 50.8 years, range 17–77) for management of rupture (n = 11), type B dissection (n = 9), or aneurysm (n = 3). All patients had bilaterally equal systolic and diastolic blood pressures (141.3 ± 19.8 and 78.9 ± 11.0 mmHg, respectively). Twenty Gore TAG and 1 Talent thoracic endografts were used; 2 cases required a combination of prosthese

Abstract:

INTRODUCTION: Cranioplasty is a routine neurosurgical procedure but carries significant morbidity. Government hospitals in lower-middle-income-countries cannot afford conventional PEEK/Titanium patient-specific 3D-printed commercial implants, which have better clinical-cosmetic outcomes than free-hand polymethylmethacrylate (PMMA) cranioplasty. Therefore, free-hand PMMA cranioplasty remains the most commonly utilised method nationally. METHODS: High-resolution preoperative CT heads were used to prefabricate three-dimensional implants utilising contralateral healthy calvariums and/or reference

This report describes prosthetic rehabilitation of a patient with dry mouth due to a complex maxillofacial defect. The patient had undergone 5 surgical operations because of repeated recurrence pleomorphic adenoma, which resulted in partial maxillectomy followed by total maxillectomy, and finally orbital resection. The patient was left with oral, nasal, and orbital communication. Rehabilitation with a silicone facial cover was planned because the patientâ€™s chief complaint was mouth dryness during sleep, and air leakage through the defects was considered a cause of this dryness.

Abstract:

The functional design of the boundaries of the prosthesis behind the molar area provides for the base to cover the mucous membrane of the alveolar tubercle, without displacement by the impression material. In the lateral areas, the base of the prosthesis should ensure free movement of the mylohyoid muscle. In the area of the retromaxillary-hyoid line, the functional state of the hyoglossus muscle should be taken into account.

Prosthetic vascular graft infection is a formidable complication after cardiac surgery. Until now, the question on the tactics of managing such patients remains open, as well as the timing of each of the treatment methods such as conservative antibiotic therapy and surgery. In addition, the choice of a method of surgical treatment in itself poses new questions for specialists in regard to what methods to adhere to including prosthesis-preserving technique, prosthesis explantation and its replacement with a synthetic or biological graft, and the use of omentum to cover the infected bed.
