Abstract
A styptic device (10) for substantially hemostatically sealing a percutaneous puncture (12) in a blood vessel (14) of a patient (11), the styptic device (10) comprising: a base (16); a main compression element (18) extending from the base (16), the main compression element (18) defining a main compression surface (24) compressible against the patient (11); and an auxiliary compression element (20) removably attachable to the base (16), the auxiliary compression element (20) defining an auxiliary compression surface (26) compressible against the patient (11). When compressed on the patient (11) substantially in register with the percutaneous puncture (12), the styptic device (10) exerts a first pressure distribution profile on the patient (11) substantially adjacent to the percutaneous puncture (12) when the auxiliary compression element (20) is attached to the base (16) and the styptic device (10) exerts a second pressure distribution profile on the patient (11) substantially adjacent to the percutaneous puncture (12) when the auxiliary compression element (20) is detached from the base (16), the first and second pressure distribution profiles being different from each other.
