Abstract:
Axial visualization systems which utilize axially aligned imaging instruments for visualizing through an imaging hood purged of blood via a transparent fluid are described where an imaging element extending from a support shaft may be aligned within a working lumen defined through a deployment catheter. The imaging element may be positioned distal to the hood in its collapsed state and within the hood in its expanded state. The imaging element may be configured to seat itself securely within the catheter or to angle itself to adjust the viewing angle. Additionally, a disposable visualization sheath having a transparent lens may also be utilized to house an imaging instrument therein.
