Publication number: 20230130710Abstract: Embodiments of the present disclosure relate to an apparatus and method for treating a bowel obstruction. An example apparatus includes a first tong element and a second tong element forming a pair of tong elements pivotally connected at a junction point and movable between an opened position and a closed position. Each tong element defines a distal end and a proximal end and a body extending therebetween.

Patent number: 7536924Abstract: A high frequency flexure-based dynamometer for measuring vibrations to use in determining cutting forces in a tool is disclosed. The dynamometer device may operate within a pre-selected high frequency range while measuring cutting forces less than about 1 N. The dynamometer may include two coupled flexures that interact to produce vibration modes at the edge of a selected bandwidth of interest. These modes may produce a frequency response function within the desired frequency band that has a magnified response and is substantially constant.

Patent number: 7449122Abstract: An electrokinetic pump for pumping a liquid includes a pumping body having a plurality of narrow, short and straight pore apertures for channeling the liquid through the body. A pair of electrodes for applying a voltage differential are formed on opposing surfaces of the pumping body at opposite ends of the pore apertures. The pumping body is formed on a support structure to maintain a mechanical integrity of the pumping body. The pump can be fabricated using conventional semiconductor processing steps. The pores are preferably formed using plasma etching. The structure is oxidized to insulate the structure and also narrow the pores. A support structure is formed by etching a substrate and removing an interface oxide layer. Electrodes are formed to apply a voltage potential across the pumping body. Another method of fabricating an electrokinetic pump includes providing etch stop alignment marks so that the etch step self-terminates.Type: GrantFiled: October 18, 2004Date of Patent: November 11, 2008Assignee: Cooligy Inc.Inventors: David Corbin, Kenneth Goodson, Thomas Kenny, Juan Santiago, Shulin Zeng
