Patent attributes
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 (206) 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) in the closed configuration, the guidewire (222) may be passed through the low pressure seal (206) while maintaining sealing around the guidewire (222). A collet (209) is movable in a radial direction to move the high pressure seal (208) between an open configuration and a sealing configuration. With the high pressure seal (208) in the sealing configuration, the guidewire (222) is locked in position.
