Polyurethanes form a large family of polymeric materials with an enormous diversity of chemical compositions and properties The wide range of properties that can be achieved with polyurethane chemistry has attracted the attention of developers of biomedical devices who see promise in the mechanical flexibility of these materials combined with their high tear strength. The authors of this book discuss polyurethanes used in a variety of biomedical applications.
Chapters available from this book
The Future of Polyurethanes
Robert Guidoin and Hans J. Griesser
Where would implantology and the biomedical devices industry be today if it were not for synthetic polymeric biomaterials such as polyurethanes? While "natural" biopolymers such as reconstituted collagen have made essential contributions to the viability of some biomedical devices, synth...
Biomedical Applications of Polyurethanes
Mylène Bergeron, Stéphane Lévesque, and Robert Guidoin
Polyurethanes (PUs) represent a very broad family of polymers. They have earned an enviable and irreplaceable position within the medical industry. The applications of PUs are limitless. However one should ascertain that PUs are indeed the best materials to manufacture devices for spe...
Surface Modification of Polyurethanes
Hans J. Griesser
Why perform surface modification of polyurethanes (PUs) when numerous publications and patents claim "biocompatible" and "blood compatible" PUs? The simple answer is that some claims are exaggerated and others only applicable to specific situations. While the mechanical properties (such ...
Developments in Design and Synthesis of Biostable Polyurethanes
Pathiraja A. Gunatillake, Gordon F. Meijs, and Simon J. McCarthy
Synthetic elastomers are frequently the materials of choice for the construction ofimplantable medical device componentry. To function effectively, the chemical and mechanical properties of the polymer must be suitable for the intended application. The polymer must also have character...
Biomedical Degradation of Polyurethanes
Patrick Vermette, Stéphane Lévesque, and Hans J. G
As discussed in the preceding Chapter, polyurethanes (PUs) generally show relatively acceptable biological responses, which have frequently led to statements that they are biocompatible. However, many researchers have pointed out a need for improved performance in some applications, s...
Biocompatibility of Polyurethanes
Yves Marois and Robert Guidoin
In the last 50 years, the development and the conception of biomaterials used for the construction of prostheses and medical devices has expanded very rapidly. A wide variety of biomaterials are now commonly implanted in the human body for the treatment of various diseases such as hea...
Additives in Biomedical Polyurethanes
Nathalie Dubé, Sahar Al–Malaika, Gaétan Laroche, and Patrick Vermette
In the preceding Chapter, industrial production of polyurethanes (PUs) was covered. The main industrial processes and sterilization techniques that apply to biomedical polyurethanes were discussed. However, the issue of using polymer additives during the preparation of commercial polyure...
Commercial Production of Polyurethanes
Stéphane Lévesque, Denis Rodrigue, Patrick Vermette, and Pathiraja Gunatillake
As discussed in the preceding Chapter, polyurethanes (PUs) involve relatively complexchemistry and synthesis procedures compared to other conventional polymers used in biomedical applications. To meet the task of engineering PU–based devices and implants that fulfil the requirements...
Synthesis, Physicochemical and Surface Characteristics of Polyurethanes
Martin Castonguay, Jeffrey T. Koberstein, Ze Zhang, and Gaétan Laroche
This Chapter constitutes the starting point that will bring the reader to the other subjects discussed in this book as, for example, the biological response and biostability related to polyurethanes (PUs) are primarily driven at the first steps with their Synthesis and processing. Many l...
