Patent ID: 7753872

Claim:
An adaptor for preparing and hydrating a hemostasis-promoting sponge for delivery to a cannula, the adaptor comprising: a hemostasis-promoting sponge; an elongated member having a first end, a second end, and a lumen extending from the first end to the second end and sized to receive the hemostasis-promoting sponge, wherein the elongated member first and second ends are unobstructed to allow the hemostasis-promoting sponge to enter into and exit the lumen, respectively; a connector provided at the first end of the elongated member for connection to a syringe to deliver hydrating fluid to the lumen of the elongated member; a fitting provided at the second end for connection to the cannula, the fitting including a retaining ring; a tapered section of the lumen tapering from a first diameter at the first end to a second diameter at the second end which is smaller than the first diameter; and a vent passage, separate from the lumen, extending through the second end of the elongated member and fluidly communicating between the lumen and an exterior of the elongated member, the vent passage including a restricting portion sized to allow hydrating fluid to be vented out of the lumen through the vent passage while substantially preventing the hemostasis-promoting sponge from passing out of the lumen through the vent passage.
