Patent number: 8932325Abstract: Among other things, there are disclosed apparatuses and methods for medically sealing an opening in a vessel or wall. For example, in medical applications, a delivery tube is provided for insertion through a sheath into a vessel (e.g. a blood vessel). A dome-shaped seal fixed to a filament, an absorbent and/or compressible buffer, and a locking member are provided in the delivery tube. The delivery tube is configured so that it can be inserted into the vessel through a sheath. Tension is maintained on the filament to hold the seal against the tube or sheath. The sheath is pulled out, which pulls out the tube at the same time, leaving the seal over the opening in the vessel wall. The locking member compresses the buffer against the outside of the vessel and with the filament holds the seal in place against the inside of a vessel.Type: GrantFiled: November 23, 2011Date of Patent: January 13, 2015Assignee: Cook Medical Technologies LLCInventors: Cleon Stanley, Ram H.

Patent number: 7913185Abstract: A graphical user interface allows a user to create an image having a pop-up menu which is exportable to a target computer without the creating user being required to know how to program in JAVASCRIPTâ„¢. Using menu selection in the application in which the image is running, the creating user may insert a pop-up menu instruction associated with an object and positioned at a desired location within the image. The inserted pop-up menu instruction then causes the creating computer to invoke its own routines that construct an exportable JAVASCRIPTâ„¢ file that allows for a pop-up menu associated with the desired object to be displayed on the screen of a target system.Type: GrantFiled: October 25, 2001Date of Patent: March 22, 2011Assignee: Adobe Systems IncorporatedInventors: Douglas S. Benson, John B. Ahlquist, Dennis Griffin

Patent number: 7568534Abstract: A polycrystalline diamond cutting element for earth boring drill bits presents regions of different abrasion resistance to the earthen formation when in operation. The cutting element has an end working surface and a region which is substantially free of catalyzing material, forming a layer. In operation, this layer wears at a different rate than the underlying material causing a pair of protruding lips to form. The end working surface may be substantially planar or frusto-conical in form.Type: GrantFiled: February 26, 2008Date of Patent: August 4, 2009Assignee: ReedHycalog UK LimitedInventors: Nigel Dennis Griffin, Peter Raymond Hughes, Andrew Bell

Publication number: 20080142267Abstract: A polycrystalline diamond cutting element for earth boring drill bits presents at least three regions of different abrasion resistance to the earthen formation when in operation. The cutting element has an end working surface and the regions, which are substantially free of catalyzing material, form a series of at least three layers. In operation, these layers wear at different rates causing a series of protruding lips. The end working surface may be substantially planar or frusto-conical in form.Type: ApplicationFiled: February 27, 2008Publication date: June 19, 2008Inventors: Nigel Dennis Griffin, Peter Raymond Hughes, Andrew Bell

Publication number: 20070203520Abstract: Endovascular filter (10) including a plurality of struts (14) with distal ends (18) adapted to anchor the filter to the vessel wall after deployment, such as by having barbs (20), the filter being adapted to be retrieved if desired. Strut distal ends (18) are coated with an antiproliferative agent (40) that inhibits the ingrowth of tissue around the filter, thereby permitting the filter to be retrieved and removed atraumatically after a prolonged period of time, thus extending the useful life of the retrievable filter. Optionally, the proximal end (22) of the filter may also be so coated, or the entire filter.Type: ApplicationFiled: January 16, 2007Publication date: August 30, 2007Inventors: Dennis Griffin, Arne Molgaard-Nielsen, Anthony Ragheb, Raymond Leonard, Neal Fearnot, William Voorhees, Thomas Kozma, Brian Bates, Thomas Osborne

Publication number: 20070153407Abstract: A re-positionable mirror in accordance with an exemplary embodiment is provided. The re-positionable mirror includes a control lever and a reflective surface. The control lever is secured to the mirror and manipulates the reflective surface into one of a first position, a second position, and a third position. The reflective surface provides a view along a first line of sight at the first position. The reflective surface provides another view along a second line of sight at the second position, the second line of sight being angularly disposed above the first line of sight. The reflective surface provides another view along a third line of sight at the third position, the third line of sight being angularly disposed below the first line of sight.Type: ApplicationFiled: December 30, 2005Publication date: July 5, 2007Inventors: Dennis Griffin, William Fultz
