Embodiment Construction

[0017] Elements or parts of elements common to the embodiments described below will be denoted by the same reference numerals.

[0018] Referring to the above-mentioned figures, reference numeral 4 generally indicates a catheter comprising a catheter body 8 extending from a proximal end 12 to a distal end 16 in the longitudinal direction X-X.

[0019] The catheter body 8 is a hollow tubular body defining at least one lumen 20 .

[0020] For the purposes of the present invention, the catheter body 8 may have a varying geometry; for example, the catheter body 8 may have a hollow circular section or even a hollow elliptical / oval section with respect to a section plane perpendicular to said longitudinal direction X-X .

[0021] As described further below, the section of the catheter body 8 also depends on the length and inclination of the ribs 40 embedded in said body.

[0022] The catheter body 8 comprises a core 24 embedded inside a flexible outer covering 28 . In other words...

Abstract

Catheters are provided which have a high capacity of axial (pushability) and rotational (torquability) movement with relative maximum flexibility and which, at the same time have the ability to adapt to at least partial variations of diameter under the thrust of other catheters or dilators travelling though the lumen or so as to flatten itself at least partially to travel through the lumen of other catheters, such as for example feed catheters.

Description

technical field [0001] The present invention relates to a controlled deformation catheter, and in particular to a catheter adapted to change the cross-section of the inner lumen so as not only to allow passage therethrough of other catheters, dilators and / or instruments of various types, but also to allow It is deformed for insertion of another catheter, such as for example a guide catheter. Background technique [0002] Catheters used in the human body (especially vascular catheters for angioplasty and stenting) require support for axial movement (pushability) and rotation (torqueability), and flexibility to move along the arterial tree and The vein travels up, for which the catheter is usually made of a metal core covered with a plastic material. [0003] Current standard catheter cores consist of mesh sheets, or for maximum flexibility, coil cores. In both cases, the catheter has a predetermined diameter, making it impossible to adapt to the possible, even very small, d...
