Patent number: 10821444Abstract: A system for preparing biological sample contains a body including a proximal side and a distal side, a plurality of mandrels, a plurality of resilient elements, a plurality of fluid dispensers, and one or more samples. The mandrels are moveably positioned within the body, where each resilient element engages a respective one of the mandrels. Each of the fluid dispensers is configured to engage a distal end of a corresponding one of the mandrels. Each sample comprises a solution containing one or more nucleic acid sequences contained within at least one of the fluid dispensers.Type: GrantFiled: March 13, 2017Date of Patent: November 3, 2020Assignee: Life Technologies CorporationInventors: Ronald Danehy, Jorge Fonseca, Jayanthi Prasad

Patent number: 8337470Abstract: An apparatus for facilitating fluid flow between an internal body structure and a device external to the body comprises a housing having proximal and distal chambers separated from one another by a wall and fluidly connected to proximal port and distal ports. The wall includes a valve selectively sealing first and second openings thereof and a canopy biased toward a sealing position sealingly surrounding the first opening. The bias of the canopy is set to define a first pressure differential at which the canopy is moved out of the sealing position to permit fluid transfer therepast in a first direction. A duck-bill stem extends through the second opening and includes a lumen extending therethrough with walls of the stem being biased toward a sealing position and configured so that, when a second pressure differential is applied at at least a second level, the first end opens to permit flow therepast.Type: GrantFiled: January 28, 2009Date of Patent: December 25, 2012Assignee: AngioDynamics, Inc.Inventors: Jayanthi Prasad, Tom Fisk, Jeff Gray

Publication number: 20070066943Abstract: Systems and methods for coupling devices such as a ventricular assist device to vascular tissues, such as a heart. In one version, a method is provided for attaching a device to vascular tissue for fluid flow. The device includes a cannula coupled to a cuff, and the method includes coupling the cuff to the vascular tissue, penetrating the vascular tissue by inserting a penetration device through the cannula, and inserting a first end of the cannula through the cuff and into the vascular tissue.Type: ApplicationFiled: September 21, 2005Publication date: March 22, 2007Applicant: ABIOMED, Inc.Inventors: Jayanthi Prasad, Farhad Zarinetchi, Emmanuel Ilongo

Patent number: 6778091Abstract: A smoke detecting chamber for use in a light-scattering type smoke detector is provided which includes a chamber cover that forms one side of the smoke detecting chamber. The chamber cover includes a plurality of first baffles that prevent external light from entering the smoke chamber. The smoke detector further includes a chamber base that forms another side of the smoke detecting chamber, the chamber base including a plurality of second baffles that intermesh with the first baffles when the smoke detecting chamber is formed.Type: GrantFiled: January 9, 2001Date of Patent: August 17, 2004Inventors: James R. Qualey, III, Louis Desmarais, Jayanthi Prasad, Lawrence G. Stanley, Donald D. Brighenti
