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.

An occlusion crossing device that includes an outer shaft having an inner lumen and an inner shaft including a distal end with a drill tip body. There is a projection extending from the inner shaft, in which the inner shaft is removably coupled to the outer shaft so that, in a first configuration, the inner shaft can move axially, and can rotate clockwise or counter-clockwise relative to the inner lumen of the outer shaft, in which, in a second configuration, the projection is configured to engage one or more engagement sites at a distal region of the outer shaft so that the outer shaft and the inner shaft rotate tighter, and further in which in the second configuration, a pulling force on the inner shaft relative to the outer shaft causes the occlusion crossing device to deflect in a first direction, and a pushing force on the inner shaft relative to the outer shaft causes the occlusion crossing device to deflect in a second direction that is opposite the first direction. Other related embodiments are disclosed.
