Publication number: 20240138845Abstract: Catheters are described that have improved flow characteristics that may be particularly helpful when delivering embolic agents within a blood vessel. One catheter includes a fluid flow modifier that is configured to create laminar fluid flow out of a distal end of the catheter to help reduce turbulence and achieve predictable fluid movement. Another catheter includes scavenging ports that are configured to suction in embolic agents that have refluxed proximally back from a distal end of the catheter.Type: ApplicationFiled: December 8, 2023Publication date: May 2, 2024Applicant: MicroVention, Inc.Inventors: George Stern, Vladimir Satchouk

Patent number: 9566413Abstract: The present technology is directed to a dilator centering device and assemblies and methods using same. In particular, a dilator centering device in accordance with the disclosed technology can be used with a sheath hub assembly. In one embodiment, a dilator centering device includes a lumen capable of receiving a dilator shaft and centering a dilator shaft with respect to the sheath hub as the dilator shaft enters the sheath hub. In one embodiment, the dilator centering device can be attached to the sheath hub during manufacturing or it can be attached at the use site. In one embodiment, the dilator centering device can be integrated with and non-removable from the sheath hub. The embodiments disclosed herein are illustrative and do not limit the scope and spirit of the disclosed technology.Type: GrantFiled: March 23, 2012Date of Patent: February 14, 2017Assignee: TERUMO MEDICAL CORPORATIONInventors: Mark Eberhardt, Hiroyoshi Ise, George Stern, Michael Miller, Yasutake Yamada, Husexin Fertac Bilge

Publication number: 20120150365Abstract: A wireless precision avionics kit is provided for retrofitting aircraft to facilitate communication between the cockpit and modern military stores without hardware or software modifications to the aircraft. The store includes an electrical interface that requires data and possibly power from the aircraft and provides for communication via a message set. The kit may be used with any aircraft that provides a rack or pylon for mounting the store and the capability to release the store. The kit may be used with aircraft having no existing capability to communicate with smart stores, with aircraft having an incompatible interface for modern stores or even with aircraft that have a compatible hardware interface for which the software is outdated.Type: ApplicationFiled: December 13, 2010Publication date: June 14, 2012Inventors: Barry A.

Patent number: 5551819Abstract: A metal end plate for a wood product including a plurality of elongated teeth protruding substantially transversely from the intermediate portion of the plate and a plurality of elongated teeth protruding substantially transversely from at least two opposed edges of the plate. These edge teeth are located such that, when the teeth are pressed into the end of a wood product, they engage the wood fibers near the outer perimeter of the end of wood product to provide restraining force at the perimeter of the end of the wood product to prevent large splits or cracks from forming or reappearing. In a preferred embodiment, the edge teeth engage the wood fibers within about 1/2 inch of the edge of the end of the wood product. Also, in a preferred embodiment the length of the edge teeth is on the order of 17/32 inch for average density wood and longer for wood of low density.Type: GrantFiled: December 29, 1994Date of Patent: September 3, 1996Inventor: E.

Patent number: 5269413Abstract: A pill container has a casing with a closed end, an open end, and a chamber. The chamber can hold the pills and communicate with the open end. A cap having an inside surface can releasably attach to the open end and close the casing. A pin is centrally secured at the inside surface of the cap. This pin is positioned to extend into the chamber of the casing when the cap is attached to the casing. A plunger is slidably mounted in the chamber of the casing. A spring mounted in the casing can urge the plunger toward the open end of the casing to hold the pills in position, so that agitation would not tend to powder the pills.Type: GrantFiled: September 4, 1992Date of Patent: December 14, 1993Inventor: George Stern
