Filed 15 Aug 95
Serial No. 08/515,499
This invention provides nurses and other health care workers with protection against accidental needle sticks. Specifically, a device has been created which protects the most susceptible areas on the back and sides of the thumb, forefinger, and the area of the hand there between. This offers the notable advantage of preventing infections from accidental needle sticks. This invention is particularly useful during the risky task of inserting a twisted or kinked needle (such as a Huber needle) into a pot-a-cath. Stage of Development: prototype built.

Separation Of Polar Compounds By Affinity Countercurrent Chromatography
Y Ma, Y Ito (NHLBI)
Filed 14 Aug 95
Serial No. 08/514,917
Patent Status: U.S. patent application pending, foreign rights available
A new and highly advantageous method of purifying polar organic compounds using affinity countercurrent chromatography, has been created. This invention permits separation of very hydrophilic organic compounds using countercurrent chromatography in which a ligand for the desired analytes is used to enhance the partitioning of polar species into the organic layer of an aqueous-organic solvent mixture. Examples of polar organic compounds which may be recovered using the present invention include: compounds having two or more functional groups on each molecule which are hydroxyl, amino, acid or lower acyl (e.g., catecholamines, carbohydrates, polyalcohols, polyamines, amino acids, peptides, and nucleic acids). Stage of Development: completed and tested. (portfolio: Devices/Instrumentation - Research Tools, devices, chromatographic)

Apparatus And Method For The In-Situ Detection Of Areas Of Cardiac Electrical Activity
H Bassen, V Krauthamer (FDA)
Filed 11 Aug 95
Serial No. 08/513,713
Patent Status: U.S. patent application pending and foreign rights available
This invention provides new means for diagnosis (e.g., two dimensional mapping) and treatment of electrically-active tissue without the need for surgery. For example, electrical activity of the heart may be mapped in vivo, in a minimally invasive manner, without cutting either the chest wall or the heart wall. The invention employs a multifibered endoscope and multiple tissue dyes to map electrical activity. This permits identification and treatment of potentially lethal electrical abnormalities without surgery. In regard to the cardiac diagnosing aspect of this invention alone, over 400,000 people die in the U.S. each year from cardiac electrical rhythm diseases. This invention provides a minimally invasive and less expensive means for diagnosis and treatment of such diseases.

Displacement Countercurrent Chromatography
Serial No. 08/263,924 filed 21 Jun 94
U.S. Patent No. 5,449,461 issued 12 Sep 95
A new method of preparative scale pH-zone refining countercurrent chromatography has been invented, which may be operated analogously to displacement chromatography. It has been discovered that use of a retainer base or acid in the stationary phase retains analytes in the column. The analytes may then be eluted using a displacer acid or base in order of increasing or decreasing pKa or hydrophobicity. This invention has many advantages, including: producing a train of highly concentrated rectangular solute peaks with minimum overlap; the retaining and displacing compositions may be switched (i.e., the retaining material may be made the displacing material, and vice versa); eluted material is provided as a salt free acid or base in an organic solvent, which can easily be separated by evaporating the solvent; the displacement mode of this invention may be utilized in a ligand-affinity separation which may cover a broad range of analytes, including nonionizable compounds; allowing the sample to be loaded onto the separation column as a suspension, or as a mixture of compounds that are only partially soluble in the solvent system, and; permitting the separation of greater volumes than with previous methods.

Method For In Situ Testing Of Integrity Of Electrical Stimulator Leads
R Schmukler (FDA)
Filed 21 Jun 94
Serial No. 08/263,312
This invention provides an in situ method for testing the integrity of the insulation of electrical stimulators leads. It allows the electrical stimulator to measure and thereby continually monitor the insulation of its leads. By being able to detect premature degradation of the leads of implanted electrical stimulators, e.g., pacemakers, unexpected failures of the device can be reduced. Replacement of the electrical stimulator leads in the heart is a traumatic process, to be avoided unless necessary. Currently available pacemakers and other implanted electrical stimulators do not allow for accurate monitoring of the lead insulation, so that advance warning of degradation may be obtained. This invention allows for the degradation of the lead insulation to be detected earlier than is now possible, thereby providing warning of potential failure before it becomes critical to the patient.

A Detection Device and Quantification Method for Therapeutic Agents in Blood
E Kohn, L Liotta (NCI)
Serial No. 08/041,438 filed 31 Mar 93
U.S. Patent No. 5,405,782 issued 11 Apr 95
New methods have been invented which provide improved determination of therapeutic agents in blood. A solid phase extraction of a solute from plasma is followed by reverse phase high performance liquid chromatography on a column of irregularly shaped C-18 liquid chromatography on a column of irregularly shaped C-18 modified silica. By comparing the chromatogram produced by this invention with a standard, a precise and accurate quantification of the amount of solute in the blood may be made. This invention also has the advantage of facilitating automation of the extraction and chromatography steps, thereby permitting rapid testing of a plurality of samples.
