DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

(10) The present invention relates to a method, a device and a kit for transferring fluids from storage and reconstitution vessels to a delivery device in a surgical environment such as an operating room. Reconstitution tools and storage vessels are generally illustrated in FIGS. 1A and 1B, while delivery device 10 in transfer mode is shown in FIGS. 2-4 and in delivery or drip mode in FIGS. 5-6. Delivery device 10 in FIG. 2B has at least two syringes that are set in a dual syringe configuration, where the delivery device 10 and the syringes can be packaged individually or together in a kit with the delivery device 10.

(11) A set of reconstitution tools are shown in FIG. 1A consisting of a pair of loading syringes 11, corresponding storage vials 13 (1-4) and spike adaptors 15. Storage vials 13(1) and (2), in one embodiment, contain substantially dry active components, preferably lyophilized proteins or plasma derived components. Storage vials 13(3) and (4), in the first embodiment, contain reconstitution solutions, such as saline or buffered aqueous solutions. Each loading syringe 11 is a hollow cylindrical tube with handles 17, an outlet 23 at an end distal to handles 17 and a plunger arm 19 that fits snuggly within the interior space of loading syringe 11 though an opening 21 in said handle 17. Retracting plunger arm 19 creates empty space between the base of plunger arm 19 and outlet 23 for loading syringe 11. Spike adaptors 15 are configured to accept vials 13 and simultaneously pierce vial septum with spikes 9. Sterile, non-metallic cannulas 8 are provided for subsequent transfer of reconstituted materials drawn into syringes 11 into delivery device 10.

(12) Device 10 is shown in the loading configuration in FIGS. 2-4 and in a drip configuration in FIGS. 5 and 6. In either configuration, device 10 comprises two supply containers provided as commercially available syringes 12 for solutions of biologic agents, such as proteins, such as fibrinogen, and of fibrinogen activators, such as thrombin, of a two-component tissue glue. Each syringe 12 comprises a hollow cylindrical syringe body 14 having a front end 16 with ports 18 and connecting pieces 90, and an open rear end 22 (not shown). Arranged in each syringe body 14 is a piston or plunger 24 in sealing abutment on the inner surface of syringe body 14. Piston 24 is held by a piston rod 26 guided out of syringe body 14 through the rear end 22. The piston rods 26 extend respectively in the longitudinal direction of the syringe bodies 14 and beyond open rear end 22. The free ends 30 of piston rods 26 facing away from piston 24 have annular flanges 32 formed thereon. These annular flanges 32 are mechanically connected to each other by a connecting element 34. Connecting element 34 is formed with two receiving recesses 36 which are laterally open and suited for insertion of the annular flanges 32 thereinto. The two syringe bodies 14 are connected to each other by a clip holding means 38 (hereinbelow referred to as a holding element). The bottom portion 16 of each syringe 12 includes a substantially flat, bottom surface that includes openings to left and right cavities. The left and right cavities are separated from each other and include tapered sidewalls which form frusto-conical cavities. The left inlet port is in fluid communication with the left outlet port with a left through bore. The right inlet port is in fluid communication with the right outlet port with a right through bore.

(13) In one alternative loading configuration, particularly as shown in FIGS. 3 and 4, device 10 includes a deployed kick stand 80 and attached funnel 100. Funnel 100 is a dual funnel with two conical openings 110, 120 joined by connection portion 115 and configured for attachment to both syringes 14 simultaneously. Conical openings 110, 120 align to ports 18. Nuts 90 are configured to releasably attach funnel 100 to the ports. In one embodiment, funnel 100 is attached by a press fit to an outside surface corresponding to the tapered interior surface on each syringe 14, rather than by locking via a screw and/or luer nuts. For initial liquid transfer into each syringe 14, vial spike adaptors 15 from each reconstitution syringe 11 are replaced with blunt soft cannula 8. Cannulas 8 are used to deliver the liquids into the delivery device syringe though opening 110, 120 corresponding to each syringe 14. Dual conical funnel 100 provides larger target for cannula placement. Each conical opening 110, 120 channels cannula 8 and liquids into each barrel of syringe 14. Blunt tipped soft cannula 8, particularly when used in association with funnel 100, provide a safer, easier and faster means of delivering the liquids into device 10.

(14) It is to be understood that any type of tips, including mixing tips, mixing spray tips, mixing drip tips, air-assist, airless spray, etc. tips can be used in accordance with the present inventive embodiments. While some drawings show drip tips and other show spray tips, any tips for mixing and expression of two components can be utilized in the present systems.

(15) In one alternative drip configuration, as show in in FIGS. 5 and 6, device 10 includes a manifold 60 includes a substantially Y-shaped member having a first and a second proximal extension 62, 64 and a distal extension 66. Proximal extensions 62, 64 are configured for operable engagement with a first and a second source of component, e.g., syringes 14. Distal extension 66 is configured for operable engagement with elongated shaft 68, as will be discussed in further detail below. Manifold 60 further includes first and second component channels (not shown). First and second component channels fluidly communicate the first and second sources of components with a first and a second lumen 73, 75 (not shown) formed in elongated shaft 68. While manifold 60, as shown, is configured to receive only two sources of component, it is envisioned that manifold 60 may be configured to receive more than two sources of biological/medicinal components. Nuts 90 are configured to attach and secure manifold 60 to inlet ports 18.

(16) Elongated shaft 68 may define a substantially solid body of silicone, plastic, polymer or other flexible material. As noted above, elongated shaft 68 includes first and second component lumens 73, 75 extending the length thereof. A wire (not shown) composed of a malleable material can also extend the length of elongated shaft 68. Wire 76 can maintain elongated shaft 68 in a bent or flexed configuration after elongated shaft 68 has been bent or flexed to accommodate a given procedure. Elongated shaft 68 is secured to distal extension 66 of manifold 60 such that first and second component lumens 73, 75 align with first and second component channels. Alternatively, elongated shaft 68 may be integrally formed at a distal end of manifold 60. As shown in FIGS. 2A, 5, 6, device 10 can be used with manifold 60 connected to elongated shaft 68 terminating with spray or drip tip 70, or alternatively tip 70 can be attached directly to manifold 60 with no elongated shaft 68.

(17) FIG. 7 illustrates the primary steps required for transferring of liquid components into delivery device 10 and then conversion from a loading configuration to a dispensing or spray configuration. To begin, a first syringe 11 with a vial adaptor 15 is caused to pierce top barrier layer in storage vial 13(3), which contains a reconstituting solution, and to withdraw the liquid therein in conventional fashion. Storage vial 13(3) is replaced on the end of first syringe 11 with storage vial (1), which preferably contains, for example, fibrinogen in substantially solid form. The reconstituting solution is dispensed into storage vial (1) to dissolve the material therein. The reconstituted liquid is then drawn back into first syringe 11 and vial adaptor 15 is replaced with a first cannula 8. These steps are repeated in a second syringe 11 using storage vials (2) and (4) and a second cannula 8. In either or both instances, the reconstitution process can be accelerated with agitation and mild heat.

(18) For loading purposes, kick stand 80 is deployed on device 10 by rotating about 90 degrees and by pulling (or retracting) the syringe plungers 30 to a predetermined position. Stand 80 elevates the inlets of syringes 14 relative to plunger handle 30 which allows reconstituted liquids to flow fully into each syringe 14. To prevent stand 80 from swinging shut, detents can be provided to lock it in the open or closed position. Once the reconstituted liquids have been transferred into each syringe 14 of device 10, kick stand 80 is rotated into a locked spray position, preferably using detents or other securement means, on device 10. Funnel 100 is removed and replaced with manifold 60 and the associated spray tip elements. Device 10 can now be utilized to spray multi-liquid components, particularly dual component formulations, such as fibrinogen and thrombin, in conventional fashion.
