Abstract: Devices, such as medical devices for inhibiting conception, and methods of using and/or making these devices. In one aspect of the disclosure, a medical device has a delivery system and a first insert, which is removably coupled to the delivery system and which is designed to be deployed within a portion of a first fallopian tube, and a second insert, which is removably coupled to the delivery system and which is designed to be deployed within a portion of a second fallopian tube. Other aspects of the disclosure include, among other things, inserts made from one or more polymers; inserts which are designed to pierce and remain in place; and inserts which are implanted through a fluid delivery system.

Abstract: A mobile cleaning workbench that may be used for manually washing equipment components, parts or other articles is provided. The cleaning station provides a source of water or other cleaning liquid for use in the washing of an article in a wash basin. A drain is provided for removal of cleaning liquid from the wash basin. Since some chemicals produce vapors which are emitted as chemical-laden articles are moved about, alternative embodiments of the invention include a ventilation exhaust system that removes the vapors from the washing area and transfers them to a remote location via appropriate ducting.

Abstract: A ratcheting handle actuator provides for a tool to actuate an intraluminal catheter system for treatment at an intraluminal site by repeated movements of the handle. This allows for actuation over a greater distance than a physician might be able to perform in a single motion while preserving a direct correspondence between the movements of the ratcheting handle and the actuation of the intraluminal device.

Abstract: A mechanical football centering device for training quarterbacks to receive a snapped football. The device includes a magnetic latch which is releasable by a motion closely simulating the signal which a quarterback gives to a human center, and includes features which allow the quarterback to adjust the football's orientation and to practice "riding the center.

Abstract: A method and apparatus for determining flow rates of well fluid constituents on a much smaller scale than with prior art equipment. Rather than testing the total fluid stream, a sample stream portion is diverted from the total fluid stream and tested. The sample fluid stream portion is separated into its various constituents, and the mass flow rate of each constituent is determined. The total mass flow rate of the total fluid stream is measured and compared with the total mass flow rate of fluid flowing through the sample stream portion, so the total flow rate of each constituent may be calculated.
