International Classification:

A61M 29/02
A61M 25/10

Abstract:

A method of limiting an inflation system pressure for dilating a region of a patient's nasal sinus passageways. The method includes grasping an inflation device. The inflation device includes a syringe including a plunger slidably disposed within a barrel, a connector for fluidly connecting an outlet of the syringe with a surgical instrument balloon, and a mechanical pressure indicator associated with the syringe, the mechanical pressure indicator including a housing and an indicator body disposed within the housing. The method also includes delivering the surgical instrument balloon to a patient's paranasal sinus target area, operating the plunger within the barrel of the syringe to deliver pressurized fluid to the surgical instrument balloon, and transitioning the indicator body to extend outside of the housing when a predetermined inflation pressure of the surgical instrument balloon is reached.

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.

International Classification:

A61B 18/14
A61B 18/12
A61B 17/32

Abstract:

A bipolar electrosurgical device is disclosed that operates in a mechanical cutting mode and a hemostasis mode. The device includes a housing and a blade assembly extending from the housing. The blade assembly forms a cutting tip and cutting window at a distal end region to provide mechanical cutting of tissue and first and second electrode assemblies to provide electrical energy to tissue. The first and second electrode assemblies can each include a rotary connection assembly to allow spatial orientation of the cutting window relative to the housing and/or cutting tip.
