Use of heparin-bonded surfaces in cardiopulmonary bypass
Perfusion, 1993Heparin surface coating is a convenient means of improving the thrombo resistance of blood-exposed surfaces. At this time, heparin can be bonded to oxygenator/heat-exchanger structures, soft venous reservoirs, cardiotomy reservoirs, centrifugal pump heads, tubings, and cannulae.

Realization of FDDI optical bypass switches using surface micromachining technology
SPIE Proceedings, 1995We report a novel fiber data distribution interface (FDDI) optical bypass switch using the surface-micromachining technology. In this design, all of the switches' components are made of polysilicon films and are monolithically patterned. The switch consists of four multimode optical fibers and a two-sided mirror sitting vertically on the top of a ...

Cardiopulmonary bypass (CPB) leads to activation of the coagulation and fibrinolytic cascades, partially associated with foreign surface contact. Hemorrhage and the need for blood products is associated with rising cost and increased risk of infection.

Neutrophil-endothelial adhesion is the initiating event in neutrophil migration to areas of infection or injury. The binding of neutrophils to endothelium depends upon adhesive glycoproteins, of which the CD11/CD18 glycoproteins are the most important.

Experimental Investigation of Wake-Induced Bypass Transition Control by Surface Roughness
Chinese Physics Letters, 2012Surface roughness is experimentally used to control the flat-plate boundary layer bypass transition induced by an upstream convected two-dimensional (2D) circular cylinder wake. It is shown that the later stage of this bypass transition is successfully postponed, at the price of accelerating the earlier transition stage. A regularisation process of the

Canal surfaces with rational contour curves and blends bypassing the obstacles
Computer-Aided Design, 2015In this paper, we will present an algebraic condition, see (20), which guarantees that a canal surface, given by its rational medial axis transform (MAT), possesses rational generalized contours (i.e., contour curves with respect to a given viewpoint). The remaining computational problem of this approach is how to find the right viewpoint.

Coagulation Patterns in Bovine Left Heart Bypass with Phospholipid Versus Heparin Surface Coating
ASAIO Journal, 1993The current study was designed to evaluate tubing sets with either polymeric phospholipids or ionically bound heparin in six bovine experiments (body weight, 70 +/- 5 kg). No heparin was given systemically. Left heart bypass was started with 300 ml of clear priming solution and maintained over 6 hours (50 ml/kg/min).

Modification of polymer surfaces to achieve a surface with enhanced compatibility is an important means of obtaining improved biomaterials. The molecular design of the novel technologies is carried out with attention to create a biomembrane-mimicking surface on medical devices. This review focuses on the comparison of the chemical composition of recent
