Viewing surgical scope for minimally invasive procedures
First Claim
1. A minimally invasive surgical apparatus comprising:
- an elongated catheter having a proximal and a distal end and at least two working channels;
a visualization device within the first working channel;
a piercing needle having a lumen within the second working channel and translatable out of a distal end of the apparatus;
a working device within the lumen of the piercing needle and translatable independently of the piercing needle out of the distal end of the apparatus;
an introducer assembly coupled to the distal end of the catheter and having an essentially rigid proximal portion and a flexible distal portion; and
a flexible cup member coupled to the flexible distal portion of the introducer assembly.

Abstract
A viewing and treatment apparatus for performing minimally invasive surgery through an opening in a patient'"'"'s chest, the apparatus includes a visualization scope with an elongated portion and a distal end, and a working device such as a tissue ablation energy delivery device. The working device is encompassed within a working channel that communicates with the distal end of the scope. In one embodiment, a bronchoscope is used whose catheter shafting includes an introducer sleeve at the distal section of the scope for providing stability during introduction to a patient'"'"'s chest while stabilizing the treatment and visualization distal ends of the scope at a treatment site. This embodiment can include a needle piercing assembly that cooperatively works with the working device such as for drug delivery. In a second embodiment a rigid endoscope with a viewing channel has an introducer member that is slidably disposed and detachable from the viewing channel and has a transparent convex distal tip which provides non-articulation at the distal end. This introducer member can also be used in conjunction with the first embodiment where the catheter shaft requires non-articulation. Both types of visualization scopes include a working channel in which the working device can translationally egress from the scope'"'"'s distal end. Additionally, the rigid introducer member can be modified to include a movable transparent rotatable member design for varying the direction which the working devices egresses the apparatus'"'"' distal end.

17. A surgical procedural apparatus for visualizing and treating tissue in a minimally invasive surgical procedure, the apparatus comprising:
-
an optical fiber for effectuating the surgical procedure;
a visualization scope having a body member at a proximal end, an elongated flexible catheter attached to the body member, the catheter having at least two channels wherein a first channel provides optical viewing at a distal end of the apparatus and a second channel for introducing the optical fiber to the apparatus, said second channel having a terminus at a distal portion of the catheter;
