A medical balloon device includes an outer member extending along an axis. An inflatable member has a proximal end extending from a first end of the outer member and a distal end. An inner member is positioned within the outer member and the inflatable member such that a first end of the inner member is coupled to the distal end of the inflatable member. A support member is movably disposed within the inner member and includes a first end configured to removably engage the first end of the inner member. Translation of the support member along the axis causes the inflatable member to move between a first position in which the inflatable member has a first length and a first profile and a second position in which the inflatable member has a second reduced length and a second reduced profile. Methods of use are disclosed.

Device for performing a surgical procedure and method

A device and method for treating bone fractures/lesions using an inflatable body is provided. The inflatable body includes a balloon having a substantially flat horizontal surface for quick easy insertion into bone beneath the fracture so as to align misaligned fragments of the fracture and/or to collapsed bone. The body has a shape and size to compress at least a portion of the cancellous bone to form a cavity in the cancellous bone and/or to restore the original position of the outer cortical bone, if fractured or collapsed. The inflatable body has a stylet attached to it's distal end so that once the inflatable body is deflated it can be twisted about the stylet to have a smaller profile so as to be easily withdrawn from the bone.

Bone fracture reduction device and methods for using the same

A device includes an outer member extending between a first end and a second end. The outer member comprises an inner surface defining a passage. The device includes an inflatable member having a first end extending from the second end of the outer member and a second end. The inflatable member includes an inner surface defining a chamber. The inner surface of the outer member is continuous with the inner surface of the inflatable member. The device includes an inner member having a first end positioned within the passage and a second end coupled to the second end of the inflatable member such that the inner member does not engage the inner surface of the outer member. Systems and methods are disclosed.

In some embodiments, an apparatus includes an elongated member, an expandable member coupled to the elongated member, and an outer sheath. The outer sheath, which can be constructed from a different material than the expandable member, is disposed about the expandable member such that an outer surface of the expandable member is in discontinuous contact with an inner surface of the outer sheath. The expandable member and the outer sheath are configured to cooperatively displace a bone structure when moving between a collapsed configuration and an expanded configuration.

Apparatus and methods for use of expandable members in surgical applications

An interspinous process spacer diagnostic parallel balloon catheter and method. The balloon catheter has a plurality of main expandable members disposed one inside another, a distal expandable member and a proximal expandable member that all can be expanded from a collapsed configuration to an expanded configuration and then collapsed again to a collapsed configuration. The device can be used to determine whether a particular patient is a candidate for implantation of an interspinous process spacer to treat the symptoms of lumbar spinal stenosis and the size of such a spacer if indicated.

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.

Anterior inflation balloon

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.
