A tube for an intravascular medical device has a longitudinal extension along a longitudinal axis. The tube comprises a tube wall having a specified thickness and a plurality of through-going slots, wherein each slot has an essentially elongated shape along a main extension extending along the circumference of the tube. At least two slots are provided in a plane perpendicular to the longitudinal axis such that the main extension of the at least two slots are in the perpendicular plane. The lengths of the slots in the same perpendicular plane P are essentially the same, and the lengths L of the slots in different planes vary along the longitudinal extension of the tube according to a predefined pattern. A sensor guide wire for an intravascular measurement of at least one variable in a living body may comprise such a tube.

The invention relates to a compression unit adapted to be arranged around a patient's forearm to provide pressure to a radial artery puncture site, wherein the compression unit comprises a unit attachment band provided with a frame, and a compression element in the shape of an inflatable bladder, the compression element is further adapted to be arranged within said frame, such that when the compression unit is arranged around a patient's forearm, the compression element provides pressure to the puncture wound when the compression element is inflated. The invention also relates to a radial artery compression system.

Dorsal forearm plate having a three-dimensional concave shape adapted to the shape of the dorsal forearm such that the dorsal forearm may rest on the forearm plate, the dorsal forearm plate has an essentially rectangular extension having opposing long sides and opposing short sides and has a substantially rigid unitary body adapted to underlie the posterior of the patient's hand, wrist and forearm, the plate is provided with two attachment bands, a distal and a proximal attachment band, adapted to attach the plate at the dorsal forearm of a patient. The shape of the side of the plate adapted to face the forearm during use, is adapted to the anatomy of the forearm in that it comprises two elongated depressions running in the longitudinal direction of the plate such that, during use of the plate, the ulnar bone and radius bone of the patient rest in the respective depression and that an elongated ridge, formed between the depressions, is adapted to extend into the softer tissue between the bones in order to orient and stabilize the forearm when attached to the plate. The invention also relates to a radial artery compression system comprising a dorsal forearm plate and a compression unit.
