Viewing surgical scope for minimally invasive procedures
First Claim
1. A surgical procedural apparatus for visualizing and treating tissue in a minimally invasive surgical procedure, the apparatus comprising:
- a) working means for effectuating the surgical procedure;
b) a visualization scope having a body member at the proximal end, an elongated sleeve member attached to the body member, the sleeve member provides optical viewing at the apparatus'"'"' distal end; and
c) a rigid introducer and viewing assembly having a length sufficient to effectuate both penetration by the working means'"'"' distal end and treatment at target tissue, the assembly including;
i) a tubular member that slidably encompasses the sleeve member, ii) a working tube defining a working channel that attaches to the tubular member wherein the working means is configurabaly disposed therein and egressable at the assembly'"'"'s distal end, and iii) an inelastic and transparent distal tip member that encloses the tubular member'"'"'s distal end wherein the working tube'"'"'s distal end attaches to the tip member thereby enabling visualization of the working channel'"'"'s distal end, whereby the introducer and viewing assembly stabilizes the apparatus'"'"' distal end and reduces active muscular tissue movement during the procedure.

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 work 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. The preferred surgical procedure is transmyocardial revascularization and the preferred working device is an optical fiber element that is translatable from the distal end of the apparatus during the procedure. The working device can optionally include a flexible piercing needle with an internal lumen which allows translation of a working device such as an optical fiber or act as a conduit for drug delivery.

22. A surgical procedural apparatus for visualizing and treating tissue in a minimally invasive surgical procedure, the apparatus comprising:
-
working means for effectuating the surgical procedure;
a visualization scope which is an articulating bronchoscope having a body member at the proximal end, an elongated flexible catheter attached to the body member, the catheter having at least two channels wherein one channel provides optical viewing at the apparatus'"'"' distal end and a second channel is a working channel for introducing the working means to the apparatus and terminating at the distal end of the catheter;
means for deflecting the distal end portion of the catheter, a proximal end of the means for deflecting is an articulating handle member that is pivotally mounted on the body member, the handle member includes an actuation means for a) controlling operation of the working means and b) translating a distal portion of the working means out from the working channel'"'"'s terminus;
actuation means includes a triggering member that interlockingly operates a spring loaded member that attaches to and advances a displacement member that attaches to a piercing needle member, the needle member has an internal lumen at the working channel'"'"'s distal end; and
an essentially rigid introducer member attached and encompassing a portion of the catheter juxtaposed to the distal end portion of the catheter, the introducer member'"'"'s length is sufficient to effectuate penetration by a distal end of the working means at target tissue undergoing the procedure thereby stabilizing the distal end of the working means, the introducer member includes a handle member at a proximal end thereof for the introducer member'"'"'s placement within a patient, and the deflecting distal end portion of the catheter includes a flexible cup member to provide a working space for unobstructed visualization and treatment of target tissue. - View Dependent Claims (23)
