Publication number: 20230256215Abstract: A sinus dilation instrument useful with a navigation system and including a handle, a rigid probe, a balloon, and an identifier device. The probe extends from the handle, forms a curved segment, and carries the balloon. The identifier device is programmed to generate a signal indicative of an instrument identification assigned to the instrument, and is a frontal, maxillary or sphenoid sinus instrument. The signal is formatted to be recognized by an IGS. Once connected, the IGS recognizes the instrument and can retrieve information indicative of a spatial location of the balloon, for example via an instrument tracking device. A surgeon can “plug and play” the sinus dilation instrument with the IGS to perform a procedure.Type: ApplicationFiled: April 25, 2023Publication date: August 17, 2023Inventors: Robert K. Vaccaro, Charles Franklin Scott Carpenter, David J. Little, II, Ali Mowlai-Ashtiani, Matthew J. Nadeau, Dana Andrew Oliver

Patent number: 10105521Abstract: An inflation device useful for inflating a balloon provided with a surgical instrument, such as a balloon sinus dilation instrument. The inflation device includes a syringe, a connector, and mechanical pressure indicator. The syringe includes a plunger slidably disposed within a barrel. The connector is configured to fluidly connect an outlet of the syringe with a surgical instrument balloon in establishing a closed inflation system between the syringe and an interior of the balloon. The pressure indicator is associated with the syringe and is configured to transition from a non-alert state to an alert state when a pressure of the inflation system has reached a predetermined level. In some embodiments, the inflation device is characterized by the absence of a pressure gauge.Type: GrantFiled: December 14, 2015Date of Patent: October 23, 2018Assignee: Medtronic Xomed, Inc.Inventors: Robert K. Vaccaro, Timothy M. Furst, Wenjeng Li, David J. Little, II, Ali Mowlai-Ashtiani, Dana A. Oliver

Patent number: 5140906Abstract: An airbag igniter having an initiator charge in an inner case and an output charge in a surrounding outer case, has a first metal header closing the inner case and a glass seal providing feed through of one or more electrical connections to the initiator charge through the first header. The outer case has a second metal header fitted to it. The second header surrounds the first header in a spaced relationship maintained by a second glass seal. The second glass seal electrically isolates the second header and outer case from the inner header for protection against accidental ignition. The dual glass seals provide protection against maloperation due to gas leakage. A ceramic washer in axial compression between the outer header and a flange of the inner header provides added assurance against failure of the second glass seal.Type: GrantFiled: November 5, 1991Date of Patent: August 25, 1992Assignee: ICI Americas, Inc.Inventor: David J.
