A method and system for fusing a region in the spine involve the use of at least one guide tube ( ) to pass instruments and substances into the spinal region in a minimally invasive manner. In the preferred practice of the method, a guide tube is anchored to a vertebra and the guide tube is moved to thereby position the vertebra. A steerable drilling tool ( ) is passed through the guide tube and steered into position to abrade at least a portion of an intervertebral disc, thereby creating a cavity in the disc. A flowing substance is passed into the cavity and permitted to solidify to establish fusion in the cavity. Optionally, an uninflated balloon ( ) is inserted into the cavity and the balloon is filled with the flowing substance to contain the flowing substance.

A computer-aided system identifies aneurysm suspects in D image datasets. The system takes the raw image dataset as input and assigns one or more points of interest (POIs) in the image data. The system determines one or more features for each POI and identifies one or more aneurysm suspects from among the assigned POIs based on the determined features.

A method for occluding aneurysms or peripheral blood vessels is provided which allows for isovolumetric, isobaric delivery of occluding agents to aneurysms or peripheral blood vessels, wherein the aneurysms or peripheral blood vessels are isolated from the general circulation until the occluding agent has stabilized or until occlusion is effected. In particular, a double balloon method for occluding aneurysms or peripheral blood vessels is disclosed wherein a first balloon is inserted into the aneurysm or peripheral blood vessel to deliver an occluding agent, and a second balloon is placed such that it substantially covers the neck of the aneurysm or peripheral blood vessel to substantially seal the aneurysm or peripheral blood vessel from the general circulation. Additionally, an aneurysm or peripheral blood vessel comprising a double balloon configuration useful for occluding aneurysms or peripheral blood vessels is disclosed.

Devices and methods for creating space within a body structure for therapeutic purposes include an expandable member disposed on the distal end portion of a catheter. Such devices and methods can be used, for example, for creating space within bone, and for injecting a filler material such as cement into the space to strengthen, repair, or otherwise enhance the bone structure.
