Apparatus and method for developing an anatomic space for laparoscopic procedures with laparoscopic visualization
First Claim
1. A laparoscopic apparatus for creating an anatomical working space underlying the skin of a patient comprising:
- a U-shaped channel guide comprising an open ended longitudinally extending distal portion and a ring shaped proximal portion having a bore extending therethrough;
a tunneling member having proximal and distal extremities and having a bore therein extending from the proximal extremity to the distal extremity and having an open end, the tunneling member being inserted through the bore of the channel guide for tunneling through tissue of the patient;
a balloon having an inflatable space and being capable of assuming collapsed and inflated conditions, the balloon being in the collapsed condition and being formed into a roll and means carried by the balloon for retaining the balloon in a roll and securing the balloon to the channel guide and the tunneling member.

Abstract
Apparatus for creating an anatomic space in tissue in a body of a patient using a cannula with proximal and distal extremities and a bore extending therethrough to provide an open end. A balloon having an inflated space is provided. The balloon is capable of assuming collapsed and inflated conditions. A retainer is carried by the balloon for forming the balloon when in a collapsed condition into a generally cylindrical roll to aid in inserting the balloon into the tissue. An obturator shaft having a rounded distal end is sized so that it extends through the cannula and into the roll. A laparoscope can be introduced into the obturator shaft to permit viewing through the obturator shaft and the balloon. An inflation tube is provided for inflating the balloon after it is disposed in the tissue to cause the balloon to progressively expand to create separation forces in the tissue to create the anatomic space.

3. A method for creating an anatomical working space for performing a laparoscopic surgical procedure underlying the skin of a patient by using a laparoscopic apparatus of the type having a channel guide with a proximal cylindrical portion having a bore extending therein and a longitudinally extending open ended distal portion, a tunneling member with proximal and distal extremities and having a bore therein extending from the proximal extremity to the distal extremity and having an open end at its distal extremity, the tunneling member being inserted through the proximal bore of the channel guide and having a portion of its length extend proximally of the distal end of the channel guide, and a balloon having an inflatable space and being capable of assuming collapsed and inflated conditions, the balloon being in the collapsed condition and being formed into a roll and means carried by the balloon for retaining the balloon in a roll and securing the rolled balloon to the channel guide and tunneling member comprising the steps of:
-
(a) inserting a laparoscope into the bore of the tunneling member; (b) making an incision in the skin of the patient; (c) introducing the tunneling member together with the laparoscope and rolled balloon into the incision; (d) advancing the tunneling member together with the laparoscope and balloon to the desired location within the body until a portion of the channel guide is disposed within the incision; (e) inflating the balloon with a balloon inflation medium to cause the balloon to expand to cause dissection and create an anatomic space and advancing the laparoscope through the open end of the tunneling member during balloon inflation to observe dissection as it is taking place; (f) deflating the balloon and removing the tunneling member and laparoscope from the channel guide leaving the channel guide and deflated balloon within the incision; (g) inserting the laparoscope into the channel guide and following the channel guide back to the dissected space; and (h) removing the channel guide and deflated balloon from the incision.

4. A laparoscopic apparatus for creating an anatomical working space between tissue layers in a body comprising:
-
a handle having a proximal portion and a distal portion and a cylindrical bore having an interior surface; a cylindrical inner ring positioned inside said bore in said handle, and having an interior annular surface and an external annular surface; a cylindrical balloon sleeve having a distal end and a proximal end, said balloon sleeve axially aligned with said bore in said handle; an inflatable balloon including an elongated neck, said elongate neck extending over said balloon sleeve and secured between said interior surface of said bore in said handle and said external annular surface of said inner ring forming a substantially fluid tight seal between said elongate neck and said interior surface of said bore in said handle, said balloon being formed into a roll; a balloon inflation lumen extending from said balloon for inflating said balloon; a tunneling member comprising a grip and a hollow shaft, said grip attached to said hollow shaft and having a cylindrical bore axially aligned with said hollow shaft, said hollow shaft insertable through said interior annular surface of said inner ring and extendable through said cylindrical balloon sleeve into said balloon, said distal end of said hollow shaft including a lip; and means for retaining said balloon in a roll and for securing said balloon to said hollow shaft and to at least said distal end of said balloon sleeve.

5. A laparoscopic apparatus for creating an anatomical working space between tissue layers in a body comprising:
-
an inflatable balloon having an elongated neck, said balloon formed into a roll; a tunneling member comprising a grip and a hollow shaft, said hollow shaft having a proximal end and a distal end with a bore extending from said proximate end to said distal end, said distal end comprising a lip partially blocking said bore, said grip attached to said proximal end of said hollow shaft and provided with a cylindrical opening axially aligned with said bore, said hollow shaft insertable through said elongate neck of said balloon and extendable into said balloon, said elongated neck attached to said hollow shaft forming a substantially fluid tight seal between said elongated neck and said hollow shaft; a balloon inflation lumen extending from said balloon for inflating said balloon; and means carried by said balloon for retaining said balloon in a roll and for securing said balloon to said hollow shaft. - View Dependent Claims (6)
