Publication number: 20200253612Abstract: A medical flow restrictor that may be used to exclude a saccular aneurysm from the circulatory system. The device, a thin walled, foil-like shell, is compacted for delivery. The invention includes the device, electroforming fabrication methods, delivery assemblies, and methods of placing, and using, the device. A device with an aneurysm lobe and an artery lobe self-aligns its waist at the neck of an aneurysm as the device shell is pressure expanded. Negative pressure is used to collapse both the aneurysm lobe and the artery lobe, captivating the neck of the aneurysm and securing the device. The device works for aneurysms at bifurcations and aneurysms near side-branch arteries. The device, unlike endovascular coiling, excludes the weak neck of the aneurysm from circulation, while leaving the aneurysm relatively empty. Unlike stent-based exclusion, the device does not block perforator arteries. This exclusion device can also limit flow through body lumens or orifices.Type: ApplicationFiled: April 30, 2020Publication date: August 13, 2020Inventor: Richard A. Hines

Publication number: 20060200234Abstract: The present invention is directed to an intravascular treatment for intracranial aneurysms. The invention consists of a patch stent and, also, a patch stent delivery system allowing one to rotate the stent to align the patch with the neck of the aneurysm. A self-expanding nitinol framework holds the patch in place, a radiopaque agent allows the patch location to be visualized and a pusher tube that is mechanically locked into the unexpanded stent is used to push the stent out of the catheter with rotational and longitudinal control necessary to align the patch with the aneurysm. A self-expanding framework is used to support a patch at the neck of the aneurysm. The patch is designed to reduce the blood circulation in the aneurysm and the stagnant blood will clot or thrombus. The thrombus will stop any current blood leakage into the brain and will dramatically reduce the possibility of future leaks or potentially deadly ruptures.Type: ApplicationFiled: March 2, 2006Publication date: September 7, 2006Inventor: Richard Hines

Publication number: 20060155367Abstract: The present invention is directed to a micro-pleated medical device assembly, preferably a micro-pleated stent assembly, comprising a tube micro-pleated to a delivery diameter suitable for intraluminal delivery. The micro-pleated stent assembly of the present invention is designed to have a substantially solid wall, and is thus particularly suited for the treatment of neurovascular aneurysms, having the ability to block the neck of an aneurysm. Sections of the micro-pleated stent may be selected for expansion to variable diameters in order to optimally fit the configuration of the vessel.Type: ApplicationFiled: January 7, 2005Publication date: July 13, 2006Inventor: Richard Hines

Patent number: 6904658Abstract: The present invention is directed to a process for forming a drug delivery device by electroplating onto a substrate a porous layer having pores of a controlled size and density and loading a drug into the pores.

Patent number: 6891805Abstract: A multi-point communications system joins a series of communications units in a series chain while providing communications between and among all of the units. Each communication unit comprises a pair of frames, preferably operating under E1/T1 protocols connected in a back-to-back arrangement through the framers' local serial busses. Communication data is placed on and extracted from a designated set of channels on the serial busses while preamble data, controlling the passage and routing of the communications data, is placed on a separate set of bus channels. One of the interconnected communications units is designated as the “parent”, and provides supervisory control over communications data, timing and flow. Designation of the parent unit may be performed on a dynamic basis to allow the communications system to dynamically adapt to changes in system size as communications units are added or dropped.Type: GrantFiled: February 6, 2001Date of Patent: May 10, 2005Assignee: Telephonics CorporationInventor: Richard Hines

Publication number: 20050090888Abstract: The present invention is directed to a pleated medical device assembly, preferably a pleated stent assembly, comprising a tube co-pleated with a balloon to a delivery width suitable for intraluminal delivery. Because the tube of the present invention transitions between its original diameter and its delivery diameter by folding and unfolding, rather than by radial contraction and expansion, the wall of the tube of the present invention may be substantially non-expandable, and thus may be substantially solid. The pleated stent assembly of the present invention is particularly suited for the treatment of neurovascular aneurysms.Type: ApplicationFiled: October 28, 2003Publication date: April 28, 2005Inventors: Richard Hines, Ben Roitberg

Patent number: 6396413Abstract: A personal alarm monitor system provides for the recording of a record of locations of a person as the person travels through a designated premises having a series of designated areas interconnected by portals or gateways, such as doorways. The person carries a receiver capable of receiving broadcasts from a series of preferably low-power transmitters specifically located throughout the premises. Pairs of transmitters are located at each gateway, one transmitter being placed in each of the adjacent designated areas to broadcast a signal primarily into the designated area about the gateway. Additional unpaired transmitters may be located at additional locations in the designated areas. Each transmitter is assigned and broadcasts a unique code corresponding to its location and status as either a gateway or non-gateway tag.Type: GrantFiled: March 11, 1999Date of Patent: May 28, 2002Assignee: Telephonics CorporationInventors: Richard Hines, Edward Starling, Fred Pulver, Robert James Pang
