摘要： The invention is an apparatus for breaking up a thrombus by introducing a tating core wire into the thrombus whereby the fibrin of the thrombus will be withdrawn from the thrombus into the rotating core wire, thereby breaking up the network of the thrombus which prevents blood flow. The apparatus includes a drive shaft housing which can be used to withdraw fluid from the area of the thrombus or to introduce medicines, such as streptokinase which will further break up the thrombus or other chemicals such as contrast agents for visualizing the vascular anatomy. The apparatus also includes a shaft housing which is provided with an expanded catheter funnel at the distal end and a venturi insert immediately proximal to the distal end. The apparatus further includes a prime mover which, in addition to rotating the drive shaft, allows for axial motion of the drive shaft relative to the drive shaft housing.

摘要： A defoaming device for separating foam and bubbles from a liquid, such as blood, is disclosed. The device can be used in conjunction with a medical device, such as a membrane oxygenator, for separating air from blood while minimizing blood contact with the antifoam agent used in the device. The device includes a reservoir and a filtering material that does not contain any antifoaming agent. This filtering material is positioned in a lower portion of the reservoir to separate foam and bubbles from the liquid. An element containing an antifoaming agent is positioned in the reservoir above the maximum surface fluid level therein and receives the foam and bubbles that rise from the filtering material. Contact of the liquid with the antifoaming agent is substantially avoided.

摘要： Autotransfusion apparatus and methods are disclosed for collecting, processing and returning blood to a patient during or after surgery. The processing step of the autotransfusion system comprises sequential rough filtering and filtering of the blood. Filtering is achieved within a single filter housing which includes a first ultrafiltration zone where blood fluids and anticoagulant are separated and removed from red blood cells, a washing zone where washing solution is injected into the remaining concentrated red blood cell solution and a second filtration zone where washing solution, residual blood fluids and anticoagulant are separated and removed from the washed and concentrated red blood cell solution. The filtration includes a rotating disc which creates a shear force upon the blood to prevent clotting and red blood cell build up along the face of filter membranes.

摘要： Systems and methods for cutting, or trimming, a catheter at a specified location along the length of the catheter. The catheter preferably includes a stop feature comprising a difference in a physical characteristic between a first portion of the catheter and a second portion of the catheter which interacts with an elongate member of the cutting system to determine the catheter is in a proper position to be cut.
