Patent number: 6076002Abstract: A biomedical electrode for an electrocardiograph or similar device is provided. The biomedical electrode includes a disposable electrode having an electrically conductive gel layer and a smooth layer film. The disposable electrode interfaces with a reusable leadwire connector having the relatively expensive metallic conductive material. The reusable leadwire adapter includes a vinyl top layer which attaches to the smooth layer film of the disposable electrode through surface attraction. The reusable leadwire adapter may include a suction cup which attaches to the disposable electrode through a partial vacuum. The reusable leadwire also includes a stud member which snaps into a standard leadwire connector.Type: GrantFiled: June 17, 1998Date of Patent: June 13, 2000Assignee: NDM, Inc.Inventors: James Vernon Cartmell, Michael Lee Wolf, Wayne Robert Sturtevant

Patent number: 5947998Abstract: Disclosed are wound closure strips which have an uniaxially oriented, silica filled, polyolefin substrate, a medical grade pressure sensitive adhesive, and a release sheet covering the pressure sensitive adhesive. Such strips are breathable, tearable to size, and may be removed from the skin with an alcohol wipe. Multiple wound closure strips are mounted on the upper surface of a backing sheet and pressure sensitive adhesive patch coated on the lower surface of the backing sheet, thereby making it possible to adhere the backing sheet to a surface near the intended point of use and, then, easily remove and handle the wound closure strips with a gloved hand. The wound closure strips may be color-coded and used not only for incisions and wounds but also for attaching catheters, and other medically related uses. Sterile packages of multiple wound closure strips make them useable in a sterile operation room arena.Type: GrantFiled: September 30, 1997Date of Patent: September 7, 1999Assignee: Technical Alternatives, Ltd.Inventors: James Vernon Cartmell, Wayne Robert Sturtevant, Albert Joseph Feczko, Michael Lee Wolf

Patent number: 5899871Abstract: A sterile wound packing material and package therefor is provided, which wound packing is flexible and conformable to deep and/or irregular shaped wounds, is compact and easily dispensed, and which can be stored indefinitely. The wound packing may also be used for absorbing wound exudate and immediately discarded or may be designed to remain in place for extended periods during healing. The wound packing includes a sterile, wound packing of a flexible material capable of absorbing wound exudate, with the flexible material being in the form of a substantially flat, coiled, spirally-cut layer and a package therefor. In certain embodiments of the invention where it is desired that the wound packing remain in place for an extended period, the flexible material is impregnated with a hydrogel, which may be a "wet" hydrogel (i.e., one containing substantial amounts of water) or a dehydrated hydrogel which is substantially devoid of water but becomes hydrated in use.Type: GrantFiled: May 31, 1995Date of Patent: May 4, 1999Assignee: NDM, Inc.Inventors: James Vernon Cartmell, Wayne R. Sturtevant, Michael Lee Wolf

Patent number: 5762620Abstract: The present invention provides a wound dressing in the form of a gauze or similar absorbent material having a partially or substantially dehydrated hydrogel material impregnated therein for absorbing wound exudate. The wound dressing is capable of absorbing large amounts of wound exudate without inhibiting the healing of the wound to which it is contacted and without the need for additional backing or adhesive layers. The wound dressing also has a pliable, soft structure which permits the dressing to be applied to wounds having irregular shapes and depths.Type: GrantFiled: September 23, 1994Date of Patent: June 9, 1998Assignee: NDM Acquisition Corp.Inventors: James Vernon Cartmell, Wayne R. Sturtevant, Michael Lee Wolf

Patent number: 5674523Abstract: An elongated, self-adhesive wound dressing is provided which includes a hydrogel layer secured to a vapor permeable bacterial barrier layer. The vapor permeable barrier layer possesses sufficient porosity such that it readily adheres to the hydrogel layer without the need for an adhesive layer. The wound dressing is adapted to be wrapped around a portion of a patient's body and secured without the use of an adhesive.Type: GrantFiled: September 1, 1995Date of Patent: October 7, 1997Assignee: New Dimensions in Medicine, Inc.Inventors: James Vernon Cartmell, Wayne R. Sturtevant, Michael Lee Wolf

Patent number: 3976055Abstract: An electrode for sensing signals such as electrocardiograph signals used with an electrolyte is formed from an electrically conductive but galvanicallly inactive material having a galvanically active conductive material at the electrolyte interface. Examples are described including a body formed from a plastic or other non-conductive binder rendered conductive by inclusion of finely divided conductive carbon and having one or more metal particles anchored to the surface of the body which contacts the electrolyte.Type: GrantFiled: November 27, 1974Date of Patent: August 24, 1976Assignee: NDM CorporationInventors: Robert Paul Monter, Albert Moore Hall, James Vernon Cartmell
