Publication number: 20240000562Abstract: A stent that is sleeved and radially expandable, and which in an expanded state provides a breathable, generally tubular structure sized and shaped for residence in a sinus or nasal cavity or passage, and in an unexpanded state has a cross-sectional diameter suitable for insertion into such cavity or passage. The sleeve limits expansion and outward pressure exerted by the stent and thereby can prevent or reduce the incidence of headache in patients, and can provide increased surface area for improved elution of chugs to nearby mucosal tissue.Type: ApplicationFiled: September 18, 2023Publication date: January 4, 2024Inventors: Jie Wen, Dana A. Oliver

Publication number: 20230293826Abstract: Implants are placed in turbinate mucosal tissue using a surgical device having a proximal grip portion and a distal hollow sharp needle portion that is manipulated using the grip portion and inserted submucosally into mucosal turbinate tissue. One or more biodegradable, drug-eluting solid implants are disposed within the needle. The implants have one or more implant withdrawal-discouraging, mucosal tissue-engaging surface features along their length. An actuator disposed within the device is used to deliver one or more of the implants from the needle into the mucosal turbinate tissue and submucosally bury at least one such tissue-engaging feature therein.Type: ApplicationFiled: May 19, 2023Publication date: September 21, 2023Inventors: Jennifer G. Medina, Drew P. Amery, Dana A. Oliver, Jie Wen

Patent number: 11759314Abstract: A stent (100) that is sleeved and radially expandable, and which in an expanded state provides a breathable, generally tubular structure sized and shaped for residence in a sinus or nasal cavity or passage, and in an unexpanded state has a cross-sectional diameter suitable for insertion into such cavity or passage. The sleeve limits expansion and outward pressure exerted by the stent and thereby can prevent or reduce the incidence of headache in patients, and can provide increased surface area for improved elution of drugs to nearby mucosal tissue.Type: GrantFiled: August 26, 2016Date of Patent: September 19, 2023Assignee: Medtronic Xomed, Inc.Inventors: Jie Wen, Dana A.

Patent number: 11666738Abstract: 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: GrantFiled: July 1, 2019Date of Patent: June 6, 2023Assignee: Medtronic Xomed, Inc.Inventors: Robert K. Vaccaro, Charles Franklin Scott Carpenter, David J. Little, II, Ali Mowlai-Ashtiani, Matthew J. Nadeau, Dana A. Oliver

Patent number: 11219537Abstract: A system and method of processing bone is disclosed. A tissue separator is utilized to separate tissue comprising at least one of muscle, periosteum and connective tissue from bone in a safe, sterile and efficient manner. In one aspect, the particle reducer can include an impeller positioned with respect to a cutting surface on a drum. At least one of the impeller and the drum is rotated by a power source such that harvested tissue frictionally engages the cutting surface. In another aspect, a source of pressurized fluid can be directed at tissue to separate bone from non-bone tissue.Type: GrantFiled: December 19, 2019Date of Patent: January 11, 2022Assignee: MEDTRONIC XOMED, INC.Inventors: Michael L.

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.
