Patent number: 9687254Abstract: Instrument and method for removing material from an intervertebral disc. The instrument includes outer and inner tubular members. The outer tubular member defines a passage and a cutting window. The inner tubular member is coaxially disposed within the passage, and defines a central lumen and a cutting tip. The cutting tip forms an open mouth having a plurality of teeth. Upon assembly, the cutting tip is exposed within the cutting window combining to define a shaving head. A manual decorticating implement is coupled to the outer tubular member and defining a scraping surface. A powered handpiece is coupled to the inner tubular member, and the shaving head is inserted into an intervertebral disc and positioned such that the cutting tip contacts targeted material (e.g., nucleus, annulus and/or end plate). The handpiece is activated to rotate the cutting tip relative to the cutting window. Contacted material is sheared between an edge of the cutting window and the teeth of the cutting tip.Type: GrantFiled: March 13, 2013Date of Patent: June 27, 2017Assignee: Medtronic Xomed, Inc.Inventors: Louis M.

Publication number: 20170056602Abstract: 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: August 26, 2015Publication date: March 2, 2017Inventors: Jennifer G.

Patent number: 9561248Abstract: Tissue and other body structures may be protected using a hydrated composition made from free-flowing substantially collagen-free rehydratable polysaccharide particles and rehydratable polysaccharide sponges. Rehydration of the particles without clumping may be carried out be dispersing the particles in a biocompatible water-miscible polar dispersant such as ethanol and combining the dispersion with sufficient aqueous solvent for the particles to convert them to a cohesive hydrogel. The hydrated composition may assist in returning an injured, inflamed or surgically repaired surface to a normal state, e.g., through one or more healing mechanisms such as modulation of an inflammatory response, phagocytosis, mucosal remodeling, reciliation or other full or partial restoration of normal function.Type: GrantFiled: July 7, 2014Date of Patent: February 7, 2017Assignee: Medtronic, Inc.Inventors: Matthew F.

Publication number: 20170007811Abstract: 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: September 21, 2016Publication date: January 12, 2017Applicant: Medtronic Xomed, Inc.Inventors: Robert K. Vaccaro, Charles Franklin Scott Carpenter, David J. Little, II, Ali Mowlai-Ashtiani, Matthew J. Nadeau, Dana A. Oliver

Publication number: 20160106960Abstract: 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: ApplicationFiled: December 14, 2015Publication date: April 21, 2016Applicant: Medtronic Xomed, Inc.Inventors: Robert K.
