Systems And Methods For Implementing Different Versions Of A Blood Separation Procedure

A blood separation device has a controller configured to execute a first and a second version of a blood separation procedure. Information regarding a blood source is analyzed to determine whether to implement the first version of the procedure or the second version. This may include an analysis of the age, weight, and/or sex of the blood source, along with whether the blood source has previously been the subject of a blood separation procedure. The second version may allow for a greater percentage of the blood or red blood cells of the blood source to be outside of the body of the blood source (in a fluid flow circuit mounted to the device) at any time during the procedure. The second version may also or alternatively allow for a higher blood cell separation efficiency than the first version, along with separating the blood in a larger blood separation chamber.

SYSTEMS AND METHODS FOR PLASMA COLLECTION

A plasmapheresis system and a method for operating a plasmapheresis system are provided by which a volume of plasma product (i.e., anticoagulated plasma) so that that the targeted volume of pure plasma in the plasma product is determined based on donor-specific characteristics. In particular, the targeted amount of pure plasma to be collected is based on the weight, or the weight and the height, of the donor. The targeted volume of pure plasma to be collected, TVP, may be a multiple of the donor's weight. Alternatively, TVP may be a multiple of the donor's total blood volume, TBV, with the TBV of the donor being determined based on the donor's weight and height. A target volume for the plasma product to be collected, TVPP, is established, and separation of whole blood into a plasma component and a second component continues until the volume of plasma product in a collection container equals TVPP.

SYSTEMS AND METHODS FOR OPTIMIZATION OF PLASMA COLLECTION VOLUMES

A system for collecting plasma comprises a separator to separate whole blood from a donor into a plasma product and red blood cells, an anticoagulant line to introduce anticoagulant to the whole blood, a touchscreen, and a controller. The controller is configured to receive donor parameters electronically from a donor management system. The controller is configured to use a target volume for plasma product and/or raw plasma which is based at least in part on donor height and weight used to calculate total donor blood volume, the target volume for plasma product and/or raw plasma based on the total donor blood volume. The controller is configured to control the system to operate at least three draw and return phases to withdraw whole blood from a donor and separate the whole blood into the plasma product and the red blood cells and to return the red blood cells to the donor.

Systems and methods for optimization of plasma collection volumes

A plasmapheresis system and a method for operating a plasmapheresis system are provided by which the volume/weight of anticoagulated plasma that is collected is optimized. In one example, a nomogram is provided that utilizes the donor's hematocrit to calculate the volume/weight of raw plasma within a plasma product having the maximum volume permitted by the FDA nomogram. In a plasmapheresis procedure having multiple collection phases followed by a reinfusion cycle in which concentrated red blood cells are returned to the donor, the volume of plasma product to be collected is calculated prior to the start of each collection cycle to account for the donor's increasing hematocrit, thus resulting in a greater total volume of plasma product to be collected during the plasmapheresis procedure.

Diffusion and infusion resistant implantable devices for reducing pulsatile pressure

Diffusion and infusion resistant implantable devices and methods for reducing pulsatile pressure are provided. The implantable device includes a balloon implantable within a blood vessel of a patient, e.g., the pulmonary artery. The balloon is injected with a fluid mixture comprising a constituent fluid(s) and a diffusion-resistant gas to provide optimal balloon volume and limit fluid diffusion throughout multiple cardiac cycles. The fluid mixture may be pressurized such that the balloon is transitionable between an expanded state and a collapsed state responsive to pressure fluctuations in the blood vessel.
