  • Patent number: 9463307
    Abstract: 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.

  • Publication number: 20160106960
    Abstract: 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.

  • Patent number: 9198997
    Abstract: Tissue and other body structures may be protected using a hydrated composition made from free-flowing rehydratable particles or a rehydratable sponge comprising substantially collagen-free dehydrothermally crosslinked thiolated polysaccharide. Rehydration of crosslinked or uncrosslinked polysaccharide particles may be carried out without clumping by 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 particles or sponge 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.

  • Patent number: 8906053
    Abstract: A method for treating a brain tumor includes providing a surgical instrument having an inner member and an outer member. The outer member has a distal region forming a cutting window and an optional distal elevator tip. The inner member is rotatably received within the outer member, and has a cutting tip that is exposed at the window. The cutting tip and the distal region of the outer member combine to define a cutting implement. An opening is created through the patient's skull to provide access to a brain tumor target site. The cutting implement is delivered through the opening to the target site. The elevator tip is inserted partially between the tumor and tissue of the target site, and the cutting tip is placed into contact with the tumor and operated to cut the tumor. The target site is selectively aspirated to remove cut tumor tissue.

  • Publication number: 20140309581
    Abstract: Chronic wounds may be treated by debriding necrotic and other devitalized tissue from the wound, and applying to the wound an extracellular polymeric substance solvating system comprising a metal ion sequestering agent, surfactant and buffering agent. The solvating system disrupts biofilms which may be present in the wound and aids or enables the resumption of normal healing.

  • Publication number: 20140263778
    Abstract: 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.

  • Patent number: 8765715
    Abstract: A method of providing hemostasis of bleeding tissue. A flexible bioresorbable foam is formed that consists essentially of carboxymethylcellulose. The flexible bioresorbable foam is crosslinked. Chain scission is performed on the crosslinked flexible bioresorbable foam to provide the flexible bioresorbable foam with a selected in-vivo residence time of between about 3 days and about 14 days. Hemostasis is caused by applying the flexible bioresorbable foam to bleeding tissue. The flexible bioresorbable foam is resorbed in-vivo. The selected in-vivo residence time is a time between the flexible bioresorbable foam being applied to the tissue and the flexible bioresorbable foam having been substantially completely absorbed into the tissue.
