This invention relates to a device to monitor the administration of a fluid through a conduit, such as intravenous fluid, and detect the completion of fluid delivery by monitoring the fluid level inside a chamber. The device will monitor, through an optical fluid sensor comprising a radiation source, two sensors, a logic means, and an indicating means, the bottom half of any “user supplied” drip chamber that is normally full during the administration of fluids. When the fluid level in the chamber drops below a predetermined level, the indicating means will initiate an electromechanical device that releases a pinching device to occlude the conduit. The pinching device is a rotary pincher that derives its force from a torsion spring and is held in the open position by the electromechanical device.

The present invention relates to a nano-imprinting stamp for imprinting nanometer-sized to mm-sized structures, the stamp (1) having a base part and a first and a second imprinting section (2,3), the first and second imprinting sections having a lithographic pattern (7) intended for imprinting in a receiving substrate. In a first aspect, the first and the second imprinting sections (2,3) are independently displaceable in a direction substantially parallel to an imprinting direction of the imprinting stamp. In a second aspect, the first and the second imprinting sections (2,3) are mechanically weakly coupled in a direction substantially parallel to an imprinting direction of the imprinting stamp. The stamp limits the effect of imperfections in or on the substrate to be imprinted with a lithographic pattern (7) and imperfections in or on the stamp and any combinations of such imperfections by localising the bending of the stamp to the base part (5) in-between the imprinting sections (2,3).

Endovascular intervention methods entail creating a temporary capillary block in the vasculature of at least a portion of a patient's organ, such as a hemisphere of the patient's brain, the capillary block essentially blocking blood flow through capillaries in the portion of the patient's organ, and performing the endovascular intervention. Distal embolism protection devices include a blood pump and at least one of a centrifuge element, a dialysis element, a cooling element, and a filtration element. The blood pump is generally capable of drawing blood from a patient's vein, circulating the blood through each of the elements so that a characteristic of a blood component may be manipulated therewith, and perfusing the modified blood into a patient's artery. A capillary block is thereby created in the vasculature of at least a portion of a patient's organ with manipulated blood components.

A scroll compressor that includes a housing and scroll compressor bodies disposed in the housing as well as a method of operation thereof is provided. The housing is separated into different chambers by a separator. One of the scroll bodies is sealed to the separator with a floating seal arrangement including a seal interface between a floating seal of the floating seal arrangement and a hub of a fixed scroll compressor body. A seal retaining ring prevents axial motion of a seal member of the seal interface during start-up operations due to pressure imbalances across the seal member.

An elastic structure is introduced percutaneously into the left ventricle and attached to the walls of the ventricle. Over time the structure bonds firmly to the walls via scar tissue formation. The structure helps the ventricle expand and fill with blood during the diastolic period while having little affect on systolic performance. The structure also strengthens the ventricular walls and limits the effects of congestive heart failure, as the maximum expansion of the support structure is limited by flexible or elastic members.
