First Claim
Patent Images
1. A minimally invasive device for use in a body, comprising:
- a tubular body comprising a proximal end, a distal end, a first lumen therebetween, and an inflation lumen; and
an inflatable member comprising an inflation chamber in communication with the inflation lumen of the inflatable member, a proximal end, a distal end, a balloon lumen therebetween that is in communication with the first lumen of the tubular body;
wherein the proximal end of the inflatable member is proximal to the distal end of the tubular body and the distal end of the inflatable member is distal to the distal end of the tubular body; and
wherein the inflatable member has a base unexpanded configuration and an expanded configuration.

Abstract
Balloon cannula systems may be used for accessing and visualizing the spine and related methods of treatment, including a forward-looking balloon system for creating a working space and the balloon system having atraumatic dissection capability to allow visualization in spine. The devices and methods described may be used, for example, to perform annulus repair, herniated disc excision, and denervation of neurological tissue; to dispense pharmacological agents and/or cell or tissue therapy agents; to diagnose disc degeneration and bony degeneration, spinal stenosis, and nucleus decompression, and to perform disc augmentation.
