DEVICES, SYSTEM AND METHODS FOR MINIMALLY INVASIVE ABDOMINAL SURGICAL PROCEDURES
First Claim
1. An obturator that is configured to be placed in a conduit and used to deliver the conduit over a guide member, said obturator comprising:
- a distal end portion, a proximal end portion and an elongate main body portion extending between said distal end portion and said proximal end portion;
a central lumen extending through said distal end portion, said main body portion and said proximal end portion and dimensioned to allow said obturator to be passed over the guide member, said distal end potion and said central lumen at said distal end portion being configured and dimensioned to form a close fit with the guide member to prevent tissues or other obstructions from entering between said obturator and the guide member;
wherein said distal end portion and said proximal end portion are rigid;
wherein said main body portion comprises rigid links; and
wherein said rigid links are articulatable in three dimensions relative to one another.

Abstract
Apparatus, tools, device and methods provided for treating a patient including: making an incision or puncture though the patient'"'"'s skin; establishing an initial tract through an opening formed by the incision or puncture; inserting a guide member having a flexible distal portion and a distal tip into the initial tract and extending the initial tract to form a delivery tract leading to a target location within the patient'"'"'s body; wherein said distal tip and at least a portion of a remainder of said guide member are transparent and delivering an obturator and conduit assembly over said guide member to place a distal end of the conduit of said obturator and conduit assembly in a location at or near the target location, said obturator having been inserted into said conduit prior to delivering said assembly over said guide member such that a distal end of said obturator extends distally out of a distal opening of said conduit wherein said obturator comprises a central lumen adapted to closely follow said guide member while sliding thereover.

10. A assembly for delivering a conduit far past an opening in a patient through which the conduit is inserted, said assembly comprising:
-
a conduit having a distal end portion, a proximal end portion, an elongate main body extending between said proximal and distal end portions, and a central lumen extending through said conduit, wherein the proximal end portion comprises a slot extending in a longitudinal direction and the distal end portion of the main body is coil-reinforced; an obturator having a distal end portion, a proximal end portion, an elongate main body portion extending between said distal end portion and said proximal end portion and a central lumen extending through said distal end portion, said main body portion and said proximal end portion and dimensioned to allow said obturator to be passed over a guide member; wherein said central lumen of said conduit is configured and dimensioned to receive said obturator therein, and wherein at said obturator, when installed in said conduit, contacts a wall of said central lumen of said conduit at least said proximal and distal end portions of said conduit. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
