摘要： A method of hydrating a sponge material for delivery to a body. The method includes the steps of placing a dry piece of sponge in a container at a first pressure. A hydrating fluid is then introduced into the container to hydrate the sponge. The pressure within the container is changed between the first pressure and a second pressure. At least a portion of the hydrating fluid is removed from the sponge, and the sponge is delivered to a bodily site.

摘要： A system including an adaptor and a syringe is used for facilitating hemostasis of a biopsy tract or other puncture wound by delivery of an absorbable sponge in a hydrated state into the wound. The adaptor includes a tapered lumen for hydrating and compressing the relatively large absorbable sponge for delivery through a relatively small cannula, such as a biopsy needle. The hydrated absorbable sponge is injected through the biopsy needle into the biopsy tract by fluid. Alternatively, the sponge may be delivered to the biopsy needle by injection of fluid and then delivered to the biopsy tract by a plunger or stylet. The implanted absorbable sponge facilitates hemostasis at the biopsy site or other puncture wound and minimizes the chance of internal bleeding. The absorbable sponge material is absorbed by the body over time.

摘要： A device for determining the depth of an incision from the epidermal layer to a puncture in a blood vessel in which the device includes an elongated member which has a lumen extending from a distal end to a proximal end. The distal end of the elongated member is configured to locate the blood vessel. After the device locates the blood vessel, a depth indicator is positioned to mark the depth of the blood vessel. In one embodiment, the elongated member includes a tapering interior surface which can receive a portion of the blood vessel. An extending control member may extend from the device at the distal end wherein the extending control member enters the blood vessel before the device locates the vessel. Fluid from the blood vessel enters the extending member through a vent hole and exits through an opening at the proximal end of the device, thereby providing a user with visual feedback that the device is moving in the desired direction toward the blood vessel.

摘要： A device, system and method for improving delivery of hemostatic material, in which the device includes a vent cap body capable of removably engaging a cannula. The vent cap has a passage extending through the vent cap body from the cannula to an exterior of the vent cap body where a restricter for restricting the flow of fluid from the cannula to the exterior. In one embodiment, the vent cap has a valve which has an opened and closed position. In the closed position, the valve is designed to provide a back pressure or resistence. When a certain force is applied against the valve, the valve moves from the closed position to the opened position, where a gas or fluid may pass through the vent cap. The vent cap is designed to help maintain the continuity of the hemostatic material during delivery of the material from the adaptor to the trial staging chamber.

摘要： A system for facilitating hemostasis of a puncture site in a blood vessel injects an absorbable sponge pledget in a hydrated state at an exterior of the blood vessel puncture to facilitate hemostasis. The system includes a tract dilator for locating the puncture, an introducer, and a plunger. The introducer includes a staging chamber for receiving the absorbent sponge pledget and a delivery chamber having a diameter smaller than a diameter of the staging chamber into which a hydrated pledget passes. The pledget is hydrated and compressed within the introducer and then ejected with the plunger to the delivery site to facilitate hemostasis of the blood vessel puncture. The system delivers the absorbable sponge pledget over a guidewire to ensure the proper positioning of the pledget over the puncture. The implanted absorbable sponge once delivered expands rapidly to fill the target site and is absorbed by the body over time.
