Perhaps your fur coat no longer fits, is out of style or no longer works in your lifestyle. Whatever your reason for wanting to part with it, here are some ways that you can go about selling your fur coat.

15 Sep 2016 Basic principle of the design of a multifunctional biomaterial coating. performance by Carmeda® bioactive surface heparin immobilization.

In normal hemostasis, the endothelium regulates the balance between anticoagulant and prothrombotic systems. It becomes particularly more challenging to maintain this physiologic hemostasis when we are faced with extracorporeal life support therapies, where blood is continuously in contact with a foreign … the PVC surface. We showed that Terumo X-coating and Medtronic Carmeda are comparable in their ability to inhibit insulin binding to PVC tubing. These coatings reduced the binding of insulin by 48%.

Immobilized heparin, as presently used in the carmeda coating, seems not to influence the formation and persistence of HPF4 antibodies. Further studies will have to prove whether HPF4 antibodies contribute to thromboembolic complications in these patients. There are several methods for the binding mechanism of heparin to the oxygenator membranes. Carmeda Bioactive Surface (CBAS), developed by Carmeda, involves the irreversible adsorption of a priming layer (polyethyleneimine). Alternating layers of PEI are treated with dextran sulfate and the crosslinking agent glutaraldehyde. After treating the coating, which includes heparin, with nitrous acid, the coating process is completed, and the result is an “end-point immobilization” of heparin. faces,11 2 separate processes for coating of extracor-poreal circuits with immobilized heparin have been available for routine clinical use for many years.

This coating reduces platelet adhesion and activation and preserves platelet function. ‡ Representing Medtronic’s commitment to perfusion solutions, Balance Biosurface expands options used by cardiovascular surgery teams for comprehensive strategies to achieve the best possible outcomes for their patients undergoing cardiopulmonary bypass.

This study compared platelet function and hemostasis activation in pediatric cardiac surgery conducted with nonheparin coating (Balance; Medtronic, Minneapolis, MN) versus heparin-based coating (Carmeda; Medtronic) circuits. There are currently many other kinds of circuit coatings that improve biocompatibility between the patient's blood and the CPB circuit.

There are currently many other kinds of circuit coatings that improve biocompatibility between the patient's blood and the CPB circuit. Although none are as effective at reducing systemic anticoagulation as Carmeda coating, many do not use heparin and such coatings are indicated for patients with heparin allergy.

The coating reduces platelet Bioactive Carmeda® heparin-coated extracorporeal circuits (ECCs) have been shown to reduce contact phase and coagulation activation during cardiopulmonary bypass (CPB). Heparin coating is therefore effective in safely reducing coagulation during routine CPB. An investigation was conducted to evaluate the effect that surface coating of the hollow-fiber membrane oxygenator had on circulating platelet count drop during cardiopulmonary bypass (CPB). Sixty patients undergoing non-emergency myocardial revascularization for coronary artery disease were randomly divided into two groups. CARMEDA ® BioActive Surface (CBAS ® Heparin Surface) This heparin bonding technology was developed by Carmeda AB, a wholly owned subsidiary of W.L. Gore & Associates, Inc. The technology has been used in a variety of applications including CPB equipment, hemodialysis catheters, ventricular assist devices, vascular stents, stent grafts, and vascular grafts. Immobilized heparin, as presently used in the carmeda coating, seems not to influence the formation and persistence of HPF4 antibodies. Further studies will have to prove whether HPF4 antibodies contribute to thromboembolic complications in these patients.
