Patent number: 6036717Abstract: The present invention comprises an embolectomy catheter for the removal of an embolus within a vessel of a patient, including a catheter shaft having a distal end with a diametrically adjustable hinged compartment thereat. The catheter shaft has a proximal end with a handle attached thereon. A longitudinally displaceable cannula is connected to the distal end of the catheter shaft and to a slidable tab in the handle, to permit controlled adjustment of the diametric size of the hinged compartment arranged adjacent the distal end of the catheter when the slidable tab is moved relative to the handle, to allow a physician to open the compartment to any desired size relative to a patient's vessel. The compartment may then be pulled through the vessel via a pull on the handle, to collect any embolus therewithin.Type: GrantFiled: June 23, 1998Date of Patent: March 14, 2000Assignee: Louisville Laboratories, Inc.Inventors: William C.

Patent number: 5681742Abstract: The present invention relates to a biological specimen and incubation container having a cylindrically shaped housing having a closed first end and an open second end. A plug, having a longitudinal bore therethrough, is anchored into a first position at the open end of the container. The container may then be supplied, via a pipette, through that bore in the plug. When the container is filled, the plug may be pushed further into the container, where it is squeezed by intermating tapered surfaces, to close the bore therein. An arrangement of annular lips and grooves in the container and the plug, anchors the plug to the container and ultimately seals and secures them together.Type: GrantFiled: September 26, 1995Date of Patent: October 28, 1997Assignee: Louisville Laboratories, Inc.Inventors: William C.
