Publication number: 20230071736Abstract: A deep vein intravenous introducer has a wheel located toward the front end of the device that can be rotated by the index finger of the user. After placement of the needle in the lumen of the vessel, the user rotates the wheel, which turns a drive wheel. The drive wheel has an outer surface that advances the guide wire through the center of the needle and into the patient. Once the guide wire is advanced into the vessel lumen the catheter can be advanced over the guide wire with a hub or finger tab on the catheter close to the index finger. The operation can be performed by one hand without moving the hand from its initial position.Type: ApplicationFiled: November 11, 2022Publication date: March 9, 2023Inventors: Nathan J. Castro, Benjamin B. Holmes, Neal K. Sikka, Alfred P. Stancampiano, Richard L. Fogel, Alan D. Fortunate, Hawaa Almansouri, Adam Corman

Patent number: 10406261Abstract: The invention describes methods for producing a biphasic nanocomposite scaffold comprising custom polymer-based core-shelled nanospheres by the physical and chemical attachment of two disparate polymeric materials whose composition can be readily modified with tissue-specific nanomaterials and products created using such methods. The custom nanospheres are constructed via co-axial wet electrospraying and can be employed to deliver compounds to the polymeric materials.Type: GrantFiled: September 15, 2015Date of Patent: September 10, 2019Assignee: The George Washington University, a Congressionally Chartered Not-For-Profit CorporationInventors: Nathan J.

Publication number: 20150238730Abstract: A catheter can be used in arterial and/or venous placement, in conjunction with ultrasound positioning. The catheter itself is made of the same materials, and is sized using the standard gauges, as current existing catheters. However, the catheter has a microtexture on the outer surface of the catheter. This microtexture efficiently and effectively reflects propagated ultrasound waves in situ, to provide a brighter and clearer image of the catheter when being placed in a patient's vessel, with ultrasound imaging equipment.Type: ApplicationFiled: February 27, 2015Publication date: August 27, 2015Inventors: Adam Corman, Neal K.
