A method of treating a bone of a patient includes identifying a portion of the patient to be protected. A cannula is provided that includes a shaft extending between opposite first and second end surfaces. The shaft incudes an inner surface defining a lumen. The cannula includes a scoop extending from the second end surface. The scoop includes an inner surface that is continuous with the inner surface of the shaft and an opposite outer surface. The cannula is inserted into the bone such that the outer surface of the scoop is positioned adjacent to the portion of the patient to be protected. A balloon is inserted into the cannula such that the balloon is positioned within the scoop. The balloon is inflated such that the balloon expands away from the scoop as the balloon is inflated and creates a void in the bone. Systems are disclosed.

Method of performing a balloon kyphoplasty procedure using a scoop cannula

A dispensing system includes a device having a body extending along a longitudinal axis between opposite proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extending through the wall and comprising a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Wherein pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a material within the proximal chamber out of the first port and the distal plunger moves a material within the distal chamber out of the second port. Kits and methods of use are disclosed.

Dispensing system and method

A delivery system is provided that includes a device having a body extending along a longitudinal axis between proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extends through the wall and includes a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a fluid within the proximal chamber out of the first port and the distal plunger moves a fluid within the distal chamber out of the second port to simultaneously actuate a bone filler dispenser. Systems and methods are also provided.

A device including a first member extending along an axis between a first end and a second end. The first end includes a first portion spaced apart from a second portion by a gap extending parallel to the axis. An inner surface of the first portion and an inner surface of the second portion defining a cavity. A pivoting member is movably disposed in the cavity and includes an inner surface defining a passageway. A second member is disposed within the passageway. The pivoting member is movable between a first orientation such that the gap has a first width and the pivoting member is rotatable to a selected trajectory relative to the axis and a second orientation such that the gap has a second width that is less than the first width and the second member is fixed in the selected trajectory. Methods of use are disclosed.

Device for performing a surgical procedure and method

A cutting device includes an elongated shaft that extends between a proximal end and a distal end. A distal arm extends from the distal end of the elongated shaft. The distal arm includes an inner surface defining a cavity and an outer surface defining a blunt tip. At least one proximal arm extends from the distal end of the elongated shaft at a position proximal to the distal arm. The at least one proximal arm having an inner surface defines a cavity including a cutting portion configured to cut tissue.

Expandable cannula and method of use

A cutting device includes an elongated shaft extending between a proximal end and a distal end. A lower portion extends from the distal end of the elongated shaft and includes an outer surface and an inner surface spaced apart from the outer surface which together form a blunt end configured as a stop so as to protect adjacent tissue. An upper portion extends from the distal end of the elongated shaft and including an inner surface. The upper portion is configured so as to be disposed opposite the lower portion. A cutting element is disposed between the lower portion and the upper portion and is configured for retractable extension beyond the distal end of the elongated shaft so as to contact tissue.

Blunt tip surgical cutting device and method

A device includes a first member extending along an axis. The first member includes a first portion connected to a second portion by a hinge. Inner surface of the first and second portions define a cavity having a pivoting member is movably disposed therein. The pivoting member includes an inner surface defining a passageway having a second member disposed therein. A cap has an inner surface that engages an outer surface of the pivoting member. The pivoting member is movable between a first orientation such that the second portion is spaced apart from the pivoting member and the pivoting member is rotatable to a selected trajectory relative to the longitudinal axis and a second orientation such that the second portion engages the pivoting member to fix the second member in the selected trajectory. Methods of use are disclosed.

A method of treating a fracture includes creating an access path to a fracture site in a bone and inserting a guidewire through the access path into the fracture site is provided. The method includes the steps of positioning a cannulated drill bit having a distal end including helical flutes configured for drilling through bone over the guidewire into the fracture site, and advancing the drill bit to create a passageway in the bone configured to receive a screw. Positioning a cannulated inflatable bone tamp over the guidewire and inflating the inflatable bone tamp to compress at least a portion of the bone in or near the fracture site so as to create a void. Delivering a bone void filler into the void through the access path to fill the void. Systems and kits are disclosed.

Bone fracture reduction system and methods of using the same

A device including a first member extending along an axis. The first member includes an inner surface defining a cavity extending through a first surface and an opposite second surface and a side surface extending between the first and second surfaces. The inner surface defines an opening extending that is in communication with the cavity. A pivoting member is disposed in the cavity and includes an inner surface defining a passageway having a second member disposed therein. An engaging member is disposed in the opening.
