Abstract

An anchored working channel includes an elongated shaft with a proximal end and a distal end, and at least one inflatable balloon positioned at the distal end of the elongated shaft and having an outer wall having an outer surface for contacting surrounding tissue, wherein the elongated shaft has a first lumen through which fluid is supplied to inflate the at least one inflatable balloon such that the balloon anchors the shaft to surrounding tissue, wherein the elongated shaft has a second lumen that accommodates at least one medical instrument and / or device inserted therein, and wherein the outer surface of the at least one inflatable balloon comprises a textured surface for preventing slippage of the outer surface on surrounding tissue.

Description

technical field [0001] The present invention relates to systems and methods for anchoring a working channel within a patient for deployment and / or use of surgical instruments and devices. More particularly, the present invention relates to a working channel with a dilation device for securing the working channel at a desired location and orientation for precise minimally invasive insertion and positioning of catheters, surgical instruments, devices, and implants within body cavities . Background technique [0002] In modern medical practice, various types of catheters, instruments, devices and implants are widely used in various medical procedures. Medical science is increasingly employing minimally invasive techniques to address and treat a variety of pathological and disease states affecting the human body. One of the advantages of this minimally invasive technique is that it can be achieved through small keyhole incisions, stab punctures, and / or through the body's natur...
