An inflatable bone tamp for performing a minimally invasive surgical procedure includes an inflatable structure that exhibits an outwardly tapering expansion profile. The outward taper can beneficially allow the inflatable bone tamp to exert greater targeted force in difficult environments. For example, in a vertebra with a compression fracture, the outwardly tapering expansion profile of the inflatable bone tamp can result in greater lifting force being applied to the endplates of the vertebra, thereby increasing the likelihood of restoring the height lost due to the compression fracture.

An inflatable bone tamp for performing a minimally invasive surgical procedure includes an inflatable structure having at least three contiguous lobes, that when inflated, cause the inflatable structure to exhibits an outwardly tapering expansion profile. By forming the inflatable structure such that the reduced-diameter junction(s) between the lobes has a greater wall thickness then the adjacent lobes, the durability and abrasion-resistance of the inflatable bone tamp can be increased.

A device includes an inflatable member extending between a first end and a second end. An inner surface of the inflatable member defines a first passageway in the first end and a chamber in the second end. An inner member is disposed in the first passageway and extends through the chamber. The inner member includes an inner surface defining a second passageway. A second end of the inflatable member is bonded to an outer surface of the inner member. A guide is member disposed in the second passageway. An outer member includes a first end having a projection including a threaded outer surface. The outer member includes an inner surface defining a third passageway having the inflatable member disposed therein. A cap includes a threaded inner surface that engages the threaded outer surface of the projection. Methods of use are provided.

A device includes an inflatable member extending along an axis between a first end having a first opening and a second end having a second opening. An inner surface of the inflatable member defines a first passageway in the first end and a chamber in the second end. An inner member is disposed in the first passageway and extends through the first and second openings. The inner member includes an inner surface defining a second passageway. A first end of the inner member includes a first opening and a second end of the inner member has a second opening. The second end of the inflatable member is bonded to an outer surface of the inner member. A guide member is disposed in the second passageway and extends through the first and second openings of the inner member. Methods of use are provided.
