    摘要: A microfluidic device is useful for modelling drug transmission across the vasculature and vascular barriers. The device includes a frame, a fluid-permeable lumen configured to carry a fluid through the frame in a first direction, a first chamber surrounding the lumen, and a second chamber surrounding the first fluid-permeable chamber. At least one surface of the first chamber is configured for deposition of a first population of endothelial cells. An outer surface of the second chamber is configured for deposition a second population of cells. The second chamber is configured to carry a fluid through the frame in a second direction. The fluid-permeable lumen is configured to allow the fluid to permeate through a wall of the lumen into the first chamber, and the first chamber and the second chamber are in fluid communication with each other.

    摘要: A medical package containing a medical article, including: a support element comprising a hollow support tube and a support cap, wherein the support element includes a first chamber configured to enclose the medical article and wherein the support cap includes a support structure configured to hold the medical article captive; a stopper configured to be coupled to the hollow support tube in such a way that the support element has a grip part that protrudes from the stopper, the grip part of the support element configured to be held by a hand of a person; a hollow protective cover configured to be coupled to the stopper in such a way as to delimit, in cooperation with the stopper, a second chamber inside which there extends the grip part of the support element, the hollow protective cover configured to be separated from the stopper, wherein when the hollow protective cover is coupled to the stopper, a part of the stopper protrudes from the hollow protective cover, and is configured to form a grip end of the stopper that is configured to be held by a hand of a person, when the hollow protective cover is separated from the stopper, wherein a part of the support element is configured to be engaged by force inside the stopper, and when the hollow protective cover is separated from the stopper, the support element remains coupled to the stopper while the support element is also separable from the stopper when a person holds the grip part of the support element and pulls the support element so as to separate it from the stopper.

    摘要: A bone plate comprises a body including an elongated opening extending therethrough, the opening being open at a distal end of the body and including a distal portion and a proximal portion, the distal portion having a width smaller than a width of the proximal portion, the width being a dimension between two longitudinal sides of the opening extending parallel to a longitudinal axis of the body, the body further including an insert including a head portion and a base portion, the base portion being shaped to be slidably mounted within the proximal portion of the opening, a diameter of the base portion being larger than a width of the distal portion of the opening such that the base portion is prevented from exiting the opening through the distal portion thereof, the insert further including a central fixation element receiving hole configured to receive a bone fixation element therethrough.
