Summary for Patent: 6,622,861

Title:	Neuro-cottonoid dispensing device and system
Abstract:	The neuro-cottonoid dispensing device comprises a tray of plastic or similar disposable material with a trough and a series of channels to accommodate neurosurgical sponges. A neurosurgical sponge comprises a string attached to an absorbent material, usually cotton. Either the sponge or the string can be radio-opaque (x-ray detectable). The absorbent part of the neurosurgical sponge is often referred to as a cottonoid by those skilled in the art. The aforementioned grooves or channels keep the strings tangle-free and the cottonoids immediately accessible. The cottonoids rest within the trough. Immediately preceding or during neurosurgery, the trough can be filled with a wetting solution, usually saline. A plastic film or similar material covers the tray and encloses the neurosurgical sponges in a sterile environment.

Patent Claims:	1. A neuro-cottonoid dispensing device comprising: a series of stringed neurosurgical sponges dispersed within; a rigid tray adapted for stacking on another tray and adhesion to a surface in a surgical field further comprising; a series of channels; a trough; and a transparent film in secure contact with the tray and completely enclosing the neurosurgical sponges. 2. The device of claim 1 wherein: the series of neurosurgical sponges and channels equal 10. 3. The device of claim 1 wherein: each channel contains at least one pinched section adapted to secure the string in the channel. 4. The device of claim 1 wherein: the rigid tray has a single leg that generally traverses the width of the tray and the bottom of which is generally coplanar with the bottom of the trough. 5. The device of claim 1 wherein: the rigid tray has a plurality of legs that are generally coplanar with the bottom of the trough. 6. The device of claim 1 or 4 or 5 wherein: an adhesive material is positioned on the bottom of the tray or leg or legs that can be engaged by first stripping a non-adhesive material from the adhesive material to expose the adhesive material for attachment to a surface in a surgical field. 7. The device of claim 1 wherein: the rigid tray contains a plurality of notches adapted to accommodate the stacking of another tray on top of it. 8. The device of claim 1 wherein: the rigid tray contains a circumferential groove adapted to accommodate the stacking of another tray on top of it. 9. A method for utilizing the neuro-cottonoid dispensing device of claim 1, wherein the method comprises: a) removing or puncturing a transparent film on the neuro-cottonoid dispensing tray: b) exposing a neurosurgical sponge resting in the trough on the tray to a wetting solution; c) wetting the neurosurgical sponge with the wetting solution; d) removing the wetted sponge for use in neurosurgery; and e) stacking trays, including said tray on top of each other when the tray containing the neurosurgical sponges has been exhausted or will no longer be used, f) disposing the spent tray or trays in a manner that does not present a bio-hazard. 10. The method of claim 9 wherein: the wetting solution is sterile water. 11. The method of claim 9 wherein: the wetting solution is sterile saline.
