Title : Role of textile materials as cardiovascular implants
Abstract:
Due to a steadily growing number of patients and considerable diagnostic and therapeutic advances, vascular diseases are becoming more and more important in general and clinical practices. The design and fabrication of synthetic vascular prostheses have been challenging to the area of surgical research over the last four decades. As vascular grafts must have specific characteristics. Textile structures are usually the materials used for arterial replacement, however they do not always meet all the requirements. The most important aspects of an arterial grafts are porosity, compliance and bio-degradability. A graft should be micro porous to provide a stable anchorage for vascular cells and stimulate cell ingrowth. Most Textile grafts are constructed either of PET (Polyethylene terephthalate) commercial name Dacron or PTEF (Polythetraflouoroethylene) known as Teflon. The design requirements for large as well as small vascular grafts are highlighted herein. Different textile structure use for grafts, Latest development in textile graft to improve kinking properties, Tissue grafts and different product available in market to solve cardiovascular problem. It is concluded that the development of vascular grafts for replacing small diameter arteries may be reached by modifying currently available synthetic materials or thru break through procedures and discoveries in the area of tissue engineering.
What will audience learn from presentation
1. Audience will get exposure on the developments in the field
2. They could apply the materials to their research
3. The new textile materials could offer a substitute to existing materials
