Publication number: 20210236100Abstract: A biopsy forceps device includes a control member; a yoke coupled to the member; jaws coupled to the yoke; and a capsule. In an open configuration, the jaws are separated to receive target tissue. In a closed configuration, cutting edges of the jaws are moved toward one another to cut tissue.

When the jaws are moved to a second position, portions of the jaws are freed from the constraint capsule and spread apart. When the yoke and the jaws are moved distally and the jaws move to the open configuration, a tissue contacting structure of the yoke extends distally to engage tissue between the jaws to anchor the engaged tissue again lateral movement as the jaws contact the tissue.Type: ApplicationFiled: December 28, 2020Publication date: August 5, 2021Inventors: Deepak Kumar SHARMA, Hitendra PUROHIT

Patent number: 7859664Abstract: The present invention provides a plurality of samples, each of which includes particles of a predetermined particle dimension, within narrow predetermined limits, dispersed in a carrier at a predetermined particle concentration. The predetermined particle dimension and the predetermined particle concentration are the same for each sample. However, advantageously, each sample has a different predetermined ratio of a value of an optical property of the particles to a value of the same optical property of the carrier. The present invention also provides a method for selecting a target sample from the plurality of samples to assess the measurement accuracy or the detection sensitivity of an optical particle analyzer as the predetermined ratio approaches 1.Type: GrantFiled: September 12, 2008Date of Patent: December 28, 2010Assignee: Brightwell Technologies Inc.Inventors: Peter Oma, Deepak Kumar Sharma
