Abstract
Abstract Apparatus and method for using disposable jackets or sheaths with many kinds of surgical devices, such as catheters and endoscopes. An inflatable balloon is mounted on an outside surface of the sheath. The sheath may also include radiopaque markers, a sterility strip, one or more attachment clips, adhesive attachment, an endcap, and/or an inflation lumen formed as a tube that extends beyond the proximal end of the sheath. The balloons of the sheath may have regular or irregular profiles and shapes, including but not limited to: a bowtie shape, a donut shape, helix, spiral, alternating on opposing sides. The balloon may be simultaneously inflated through a common lumen or they may separately inflatable through separate lumens.
