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. Following experimental evaluation, these devices have become available for

Cardiopulmonary bypass with a surface-heparinized extracorporeal perfusion system.
ASAIO transactions, 1991To evaluate the effect of surface heparinization on platelet consumption during cardiopulmonary bypass (CPB) ten pigs were placed on CPB for 3 hours. All pigs were injected with autologous Indium-111 labeled platelets (300-420 uCi) 24 hours prior to CPB and were systemically heparinized prior to cannulation for CPB.

Towards navigation on the heart surface during coronary arterty bypass grafting
International Journal of Computer Assisted Radiology and Surgery, 2008Coronary artery bypass grafting (CABG) is the standard treatment for advanced coronary artery diseases. In a preoperative MSCT, both wall plaque formations and resulting optimal anastomotic site are visible to the surgeon. During surgery, the identification of this position on the surface of the heart is of utmost importance for an effective ...

The cardiopulmonary bypass (CPB) circuit induces blood activation and a systemic inflammatory response in cardiac surgical patients. The CPB circuit treated with surface-modifying additive (SMA) has been found to reduce blood activation by in vitro and ex vivo experiments.

Swarm control with collision avoidance for multiple underactuated surface vehicles
Ocean Engineering, 2019In this paper, a novel swarm control strategy based path following guidance is addressed for multiple underactuated surface vehicles (USVs) with complex unknowns including uncertain dynamics and time-varying disturbances.

Study of the Free Surface Flow on an Ogee-Crested Fish Bypass
Journal of Hydraulic Engineering, 2008A study of the free surface flow on an ogee-crested fish bypass is presented. The commercial computational fluid dynamics (CFD) code Fluent 6.1 was used to perform the simulations. Structured/unstructured hybrid grids were used to accommodate the complex geometry that included gate slots, flow control gates, and an aeration slot.

Surface Modified Cardiopulmonary Bypass Circuits: Modifying the Inflammatory Response
Seminars in Cardiothoracic and Vascular Anesthesia, 2002As a consequence of an aging population demographic, now more than ever, researchers in cardiac surgery must focus on means to improve the methods and technologies related to cardiopulmonary bypass. This review presents a classification of the currently available options for biomaterial modification for cardiopulmonary bypass circuits.

Perfusion, 2009
It is well known that extracorporeal surfaces have the ability to bind such drugs as fentanyl, nitroglycerine and propofol. Adsorption of the injectable anesthetic agent Diprivan® (propofol) onto uncoated and heparin-coated extracorporeal surfaces during cardiopulmonary bypass (CPB) has been previously investigated; however, propofol adsorption onto ...

The bypass tracts of the WFW syndrome may be situated anywhere along the AV ring. Accurate localization of such tracts has in the past been largely effected by electrophysiologic studies, particularly epicardial mapping. During recent years, however, criteria for localization of the bypass tracts from the conventional 12-lead ECG have become ...
