Publication number: 20240081791Abstract: A disposable cartridge can be used for biofluid sample collection, preparation, and mixing with reagents. After sample collection, the cartridge can be inserted into a reader for sample analysis. This system can be used for detecting and measuring analytes, such as drugs, in saliva for example. This is useful for point of test detection of drugs in applications such as workplace drug testing and driving under the influence of drugs testing.Type: ApplicationFiled: September 18, 2023Publication date: March 14, 2024Inventors: Ashutosh SHASTRY, Pranav CHOPRA, Leah YABLOK, Ameya KANTAK, Sukhleen SAINI

Patent number: 9936905Abstract: A device for detection or measurement of a carbohydrate analyte in fluid comprises: an optical sensor comprising components of an assay for carbohydrate analyte, the readout of which is a detectable or measurable optical signal, and a light guide having a distal portion optically coupled to the assay components and a proximal portion; and a reader for interrogating the optical sensor, the reader comprising an assay interrogating system including a lens; and an interface portion forming part of at least one of the optical sensor and the reader, the interface portion being capable of removably constraining the proximal portion of the light guide and the lens of the assay interrogating system in an optically coupled arrangement. The device may be combined with an insulin-infusion system.Type: GrantFiled: October 13, 2014Date of Patent: April 10, 2018Assignee: Medtronic MiniMed, Inc.Inventors: Eric Allan Larson, Voltaire Isaac Lebron, Kevin Holz, Jasson Rodriguez, Ameya Kantak, Soren Aasmul

Patent number: 9308325Abstract: Described here are methods, devices, and kits for microjet drug delivery. The devices described here may be modular or non-modular. The modular devices typically include a first module having a drug reservoir and a nozzle in fluid communication with the drug reservoir and a second module having an actuator and a power supply. The power supply provides power to the actuator and when the first and second modules are coupled, the actuator is capable of acting on a dispensing member causing it to dispense a drug in liquid form from the drug reservoir via the nozzle at a velocity sufficient to penetrate skin. Other devices described include a nozzle, a reservoir in fluid communication with the nozzle, a dispensing member, and an actuator. In these devices, the nozzle has at least one feature that enhances nozzle contact with the skin in order to reduce lateral drug leakage about the nozzle.Type: GrantFiled: June 19, 2007Date of Patent: April 12, 2016Assignee: Corium International, Inc.Inventors: Ravi Srinivasan, Richard C. Urso, Ameya Kantak, Christoph Pistor, Takashi Yogi

Publication number: 20120247642Abstract: A method for making a microstructure includes: providing a film (100) on a release liner (110); feeding the film through a cutting plotter (10); cutting the film with a knife blade (34) of the cutting plotter to form a microstructure pattern; peeling the microstructure pattern from the release liner; and transferring the microstructure pattern to a substrate (170). The cutting plotter for making microstructures includes a knife head with a knife blade disposed adjacent a feed mechanism (20), a motor (42) and control system coupled to the knife head for selectively moving the knife head in relation to the film, and the control system and the knife head having an addressable positioning resolution less than approximately 10 ?m.Type: ApplicationFiled: November 30, 2011Publication date: October 4, 2012Inventors: Daniel A. Bartholomeusz, Ameya Kantak, Sung Lee, Srinivas Merugu, Himanshu Sant, Ronald W. Boutte, Bruce K. Gale, Charles Thomas, Brenda Marie Thomas
