Problems solved by technology

[0043] The problem with this form of distal placement action through the bladder wall is that it is only unidirectional; that is, it only prevents the tip of the catheter from being inadvertently pulled out of the wall of the bladder while allowing the catheter to pass freely further into the bladder , and retracts to the shell structure at the point
Self-management is forbidden due to all the shortcomings of the existing technology
In addition, injury, infection, and discomfort may result from unskilled or inappropriate technique

Embodiment Construction

[0252] The present invention allows many variations and applications in both apparatus and method to those skilled in the art. For example, in accordance with the present invention, there is provided a rotational advancement structure and method applicable to a range of medical devices that have heretofore relied entirely or substantially on push advancement techniques for penetrating body passages. Such devices include catheters, dilators, and occluders for mammalian genitourinary or gastrointestinal passages, such as the urethra or ureters, for common purposes associated with such devices, where no limitation of the passage walls or membranes is intended. cut or crack.

[0253] catheter

[0254] now refer to figure 1 , 2 and 3, the threaded catheter 101 for males consists of a tube 102 with an external thread 104 to which a flow control device 104 can be attached. Tube 102 is extruded from a polyurethane material, has an inner diameter of 0.06 inches, an outer diameter...

Abstract

Apparatus for visualizing tissue, the apparatus comprising: a tube sized to receive visualization apparatus disposed within the lumen of the tube; a deformable helical thread disposed on the exterior surface of the tube, the deformable helical thread (i) being transformable between a first configuration wherein the deformable helical thread comprises a reduced profile and/or a reduced rigidity and a second configuration wherein the deformable helical thread comprises an expanded profile and/or an increased rigidity, and (ii) when in its second configuration, when the tube is disposed in a bodily passageway so that the deformable helical thread engages the interior side wall of the passageway, the rotation of the tube will induce a relative movement between the tube and the side wall of the passageway; and a thread varying element dynamically varying at least one of the height of the deformable helical thread and the rigidity of the deformable helical thread.
