Patent number: 5669931Abstract: An occlusive implant includes an elongated member having an end, a portion proximal to that end, and a portion distal to that end. The proximal portion is sufficiently flexible so that it can be folded upon itself and maintain that configuration without further restraint. At least a portion of the distal portion is preformed to have a first configuration when in a first state and a second configuration when in a second state. The distal portion second configuration has a flow resistance substantially greater than that of the proximal portion. When discharged in the region to be occluded, the proximal portion is forced into a mass around at least a portion of the distal portion secondary structure. As the mass builds in size, it is believed to frictionally engage the surrounding vasculature wall and anchor the implant thereto. The occlusive implant preferably is provided in an introducer cartridge for delivery in vivo.Type: GrantFiled: April 2, 1996Date of Patent: September 23, 1997Assignee: Target Therapeutics, Inc.Inventors: David Kupiecki, Cong Thach, John E.

Patent number: 5523745Abstract: A tongue activated communications controller for use by disabled or other persons to control a wide variety of devices, and which includes a dental appliance fitted to the user's palate, and a keyboard with a plurality of tongue activatable switches for generating a signal depending upon which switch has been selected, and upon the status of a battery voltage level. The communications controller includes a radio frequency transmitter which uses magnetic flux linkage for transmitting the signal. The communications controller further includes a receiver for converting the transmitted signal into digital form, and also includes a micro-processor based controller unit for processing the received data, and for communicating with the attached devices which the user wishes to control. Data is sent from the transmitter using a fixed transmission time, digital pulse code modulation technique to achieve ultra low power consumption in the transmitter.Type: GrantFiled: April 18, 1994Date of Patent: June 4, 1996Assignee: Zofcom Systems, Inc.Inventors: Daniel Fortune, John E.
