A haemostasis device (200) comprises a low pressure seal (206) and a high pressure seal (208). A tubular bayonet (201) is movable from a retracted configuration to an inserted configuration to move the low pressure seal (20 6) between a closed configuration and an open configuration. With the low pressure seal (206) in the open configuration, a guidewire (222) may be inserted through the low pressure seal (206), and with the low pressure seal (206) while maintaining sealing around the guidewire (222). A collet (209) i s movable in a radial direction to move the high pressure seal (208) between a n open configuration and a sealing configuration. With the high pressure seal (208) in the sealing configuration, the guidewire (222) is locked in positio n.
