Patent number: 8628555Abstract: An apparatus and method for ejecting fluid from a fluid delivery system. The fluid delivery system has a pneumatic assembly that when triggered injects gas into a hydraulic assembly, which in turn ejects fluid through an external interface. An electronic interface displays various measurements, for example, how much fluid has been ejected and if the hydraulic system is closed the pressure of the system. The pneumatic assembly can also be depressurized such that fluid can reenter the hydraulic assembly through the external interface.Type: GrantFiled: February 23, 2012Date of Patent: January 14, 2014Assignee: Boston Scientific Scimed, Inc.Inventors: Stephen J. Perry, Michele B. Carter, David R. Conti, Thomas F. Janecek, Bryan D. Knodel, Anthony Scott Hollars, Peter Crowley, Donald C. Hovey, William Lucas Churchill, John B. Golden, Yam Chin, Mark L.

Patent number: 8427766Abstract: Optical assemblies for use in medical or other devices so as to image an object under examination onto an image sensor include a plurality of lens elements that can be retained in lens barrel. The lens elements and the lens barrel can be sealed with a compressible gasket. In one example, at least one lens element is made of an injection-moldable plastic and at least one lens element is made of a relatively dispersive optical glass. A lens barrel diameter or lens diameter can be selected to permit access to the object under examination with surgical or other tools. Aperture plates can be situated so as to reduce flare in the object image.Type: GrantFiled: November 22, 2010Date of Patent: April 23, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Alexander Ning, Robert Lu, William Lucas Churchill, Sergey S.

Patent number: 8353493Abstract: Various apparatuses to attach a first medical device to a second medical device are described that allow the physician to grasp only a single device while the other device remains securely attached to the one being grasped. The apparatuses, once they are attached to the first medical device, are designed to be easily and quickly attached and detached to a second medical device, normally only requiring the use of one hand. Furthermore, the apparatuses oftentimes include a base that can easily couple and decouple from the portion that is attached to the second medical device so that if the need arises to separately use the second medical device, it can be decoupled from the first medical device without completely removing the apparatus from the second medical device.Type: GrantFiled: February 7, 2008Date of Patent: January 15, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: John B. Golden, John O. McWeeney, Christopher A. Benning, Robert Castoldi, John F. Howard, Brian Intoccia, Gary Kappel, William Lucas Churchill
