    摘要： A chest drainage system, including a circulation assembly having an intake for taking fluid into the system and an exhaust for exhausting fluid out of the system. An intake flow device is configured to selectively control fluid flow through the intake and an exhaust flow device is configured to selectively controlling fluid flow through the exhaust. The circulation assembly has a first configuration and a second configuration such that transitioning between the first and second configurations during operation of the circulation assembly displaces at least a portion of fluid within the system with fluid from outside the system via the intake and the exhaust. A sensor is arranged in fluid communication with the fluid within the system and configured to detect a concentration of a reference fluid in the fluid in the system.

    摘要： An endovascular fixation device includes a first portion and a second portion connected to the first portion to define a central lumen extending longitudinally through the portions. The first portion includes a first radially expandable ring and at least one first connector, connected to the first ring, configured to cause at least one first flarable crown of the first ring to flare radially outwardly relative to other portions of the first ring when the first ring is expanded from a retracted position to an expanded position. The second portion includes a second radially expandable ring and at least one second connector, connected to the second ring, configured to cause at least one second flarable crown of the second ring to flare radially outwardly relative to other portions of the second ring when the second ring is expanded from a retracted position to an expanded position.

    摘要： A chest drainage system including a collection device configured to receive fluid from the pleural cavity of a patient. A sensor is included to detect a pressure differential in the fluid. A display is configured to display a trend in occurrences of changes in pressure of the fluid over time in predetermined time increments based on a number of detections of pressure differentials that exceed a predetermined pressure differential during each of the predetermined time increments. The trend is correlative to the percentage of time that the patient is deemed to have an air leak in the pleural cavity in the predetermined time increments. The trend is derived from a ratio of the quantity of respiratory cycles of the patient for which the predetermined pressure differential is detected (QRCleak) in the predetermined time increments to the total quantity of respiratory cycles of the patient in respective predetermined time increments (QRCtotal).

    摘要： A stent device includes generally cylindrical rings aligned along a longitudinal axis, and interconnected by interconnecting members. Each interconnecting member includes a first coupling end, a second coupling end, and an elongate portion therebetween. The first coupling end, the elongate portion, and the second coupling end combine in either a first orientation or a second orientation, which are substantially mirror images. For each interconnecting member, the first coupling end can intersect with a midpoint of a transition region of a substantially repeating curved segment on one of the rings, and the second coupling end can intersect with a midpoint of a curved segment of a different and immediately adjacent ring. The interconnecting members can be arranged in rows extending longitudinally along the device. Along each row, consecutive interconnected members alternate between the first orientation and the second orientation. A cover may be provided over the stent device.

    摘要： A method of making expanded fluoropolymer articles thermally bonds portions of expanded fluoropolymers together, without using an adhesive or crushing force, to produce stronger bonds at the joint between the expanded fluoropolymers than the bonds within the constituent expanded fluoropolymers. The method involves placing the portions of expanded fluoropolymers to be thermally bonded together in intimate contact with each other after wet-stretching the expanded fluoropolymers, and removing the wetting agent used to wet-stretch the expanded fluoropolymers, without subsequent expansion or stretching, to yield an expanded fluoropolymer article exhibiting unexpected and superior properties that can be used in a variety of medical and industrial applications.
