1. A medical device for treating disorders within an epidural space, comprising:
- a body;
a catheter portion connected to said body at a proximal end and extending from said body to a distal end;
an inflatable member disposed on an exterior surface of said catheter portion and spaced away from said distal end, such that said distal end of said catheter extends beyond said inflatable member so as to penetrate patient tissue ahead of said inflatable member during use; and
a steering mechanism integrated into said catheter portion, wherein the catheter portion is flexible and the steering mechanism controls an angle of the distal end with respect to an adjacent segment of said catheter portion such that said distal end and said inflatable member can be steered without, or after being advanced beyond an end of, a guidewire;
an optical system, connected to said body, configured to obtain an image of said epidural space around said distal end of said catheter and provide that image to an operator of said medical device;
wherein said medical device is specifically configured for treating disorders within an epidural space with minimal damage to a patient.

Abstract
Devices for and methods of treating afflictions occurring in a body cavity, such as the epidural space. The methods and devices provide for fluoroscopic assisted placement of a fiber optic catheter/scope with a balloon tip. These devices and methods would perform decompression surgery, neuroplasty, and mechanical lysis of adhesions (and other afflictions), as well as allowing small operating and therapeutic instruments under direct visualization.

12. A method of operating a medical device to treat an epidural space of a patient, wherein said medical device includes
a body, a catheter portion extending from said body and having a distal end, an optical system, connected to said body, configured to obtain an image of said epidural space around said distal end of said catheter and provide that image to an operator of said medical device; -
a steering mechanism integrated into said catheter portion, and an inflatable member disposed along said catheter portion and spaced away from said distal end, said method comprising; inserting said distal end of said catheter into said epidural space of said patient; obtaining an image of said epidural space with said optical system to locate an area of said epidural space to be treated; penetrating tissue in said epidural space with said distal end of said catheter portion by applying force to said body of said device; then inflating said inflatable member disposed along said catheter portion behind said distal end in tissue already penetrated by said distal end to apply pressure to the penetrated tissue, and steering the catheter portion with the steering mechanism inside said epidural space to locate said tissue that is penetrated with said distal end, wherein the catheter portion is flexible and the steering mechanism controls an angle of the distal end with respect to an adjacent segment of said catheter portion such that said distal end and said inflatable member can be steered without, or after being advanced beyond an end of, a guidewire. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A medical device comprising:
-
a body comprising a locking collar; a shaft connected to said body by said locking collar at a proximal end of said shaft and extending from said body to a tapered distal end that is configured to penetrate tissue to be treated, said distal end penetrating the tissue due to force applied by hand to said body by an operator of said device; an inflatable member disposed on an exterior surface of said shaft and spaced away from said distal end, such that said tapered distal end of said shaft extends beyond said inflatable member so as to penetrate patient tissue ahead of said inflatable member during use, said shaft further comprising a fluid pathway for inflating said inflatable member by introducing fluid into said proximal end of said shaft at said body and delivering that fluid to said inflatable member, wherein the fluid is drawn from a closed reservoir disposed inside said body and having a specific, limited amount of fluid therein such that inflation of the inflatable member can be limited so as not to exceed a predetermined amount or pressure, said body further comprising a pump for moving fluid from said reservoir in said body to said inflatable member through a manifold anchored to said body and from said manifold into said fluid pathway; a steering mechanism integrated into the shaft and controlled by controls on said body, wherein the distal end of said shaft is flexible and the steering mechanism controls an angle of the distal end with respect to an adjacent segment of the shaft such that said distal end and the inflatable member can be steered without, or after being advanced beyond an end of, a guidewire, said steering mechanism comprising wires passing trough ports in said manifold and extending along said shaft; an optical system comprising at least one pathway integrated into the shaft through which illumination can be provided to said distal tip of said shaft and through which images can be obtained of an environment at the distal end of the shaft, said at least one optical pathway being connected to said manifold; and a catheter integrated into the shaft through which either a tool or fluid can be introduced at the body and delivered at said distal end of the shaft, wherein said device is specifically configured for use in an epidural space.
