Patent number: 11476557Abstract: An antenna element transfers a radiofrequency signal and dissipates heat. The antenna element includes a periphery and first and second pairs of fins. The periphery has a length and a width with the length approximately equaling the width. The first and second pairs of fins extend in height from inside the periphery. The first pair of fins are separated by a shared gap for transferring a first polarization of the radiofrequency signal, and the second pair of fins are separated by the shared gap for transferring a second polarization of the radiofrequency signal that is orthogonal to the first polarization. An antenna array includes multiple instances of the antenna element for transferring the radiofrequency signal and for dissipating the heat.Type: GrantFiled: August 6, 2021Date of Patent: October 18, 2022Assignee: United States of America as represented by the Secretary of the NavyInventors: Satish K. Sharma, Jia-Chi Samuel Chieh

Patent number: 7559451Abstract: A full thickness resection device comprises a control handle including an actuator wherein, when the device is in an operative position within a body lumen of a patient, the control handle remains outside the patient's body and a working head assembly coupled to a control handle by a flexible sheath, wherein, when the device is in the operative position; the working head assembly is located within a body lumen of the patient adjacent to a portion of tissue to be treated, the working head assembly including a tissue stapling mechanism including first and second tissue stapling members moveable relative to one another in combination with a first cable extending from the actuator through the flexible sheath to the first tissue stapling member so that, when the actuator is operated to draw the first cable proximally from the sheath, the first tissue stapling member is moved in a first direction relative to the second tissue stapling member.Type: GrantFiled: July 29, 2005Date of Patent: July 14, 2009Assignee: Boston Scientific Scimed, Inc.Inventors: Satish K. Sharma, David I. Freed, Nicholas Patronik, Jeffrey M. Wendlandt

Patent number: 5594115Abstract: Recombinant fusion proteins which comprise a biologically active polypeptide portion and metal chelating peptide are disclosed. The fusion proteins contain metal chelating peptides which have at least three and preferably six alternating histidine residues. Fusion proteins which contain metal chelating peptides that are substrates for dipeptidylpeptidase I are also disclosed. Additionally, a method of obtaining desired polypeptides by producing recombinant fusion proteins and purifying them with immobilized metal ions is disclosed. A kit for purifying desired polypeptides is also disclosed.Type: GrantFiled: December 29, 1994Date of Patent: January 14, 1997Assignee: Pharmacia & Upjohn CompanyInventor: Satish K. Sharma

Patent number: 5171662Abstract: A method for identifying compounds that inhibit HIV protease is disclosed. A substrate that comprises an HIV protease cleavage site is combined with HIV protease and test compounds. Cleavage of the substrate indicates protease activity and can be detected using antibodies against a cleavage product which do not cross react with uncleaved substrate. A method of detecting the presence of anti-HIV protease antibodies in a sample is also disclosed. A substrate is combined with the sample and HIV protease. Detection of substrate cleavage indicates that the protease is active and that there is an absence of neutralizing anti-HIV protease antibodies.Type: GrantFiled: April 4, 1991Date of Patent: December 15, 1992Assignee: The Upjohn CompanyInventor: Satish K. Sharma
