This invention concerns a guide catheter comprising a hollow tubular body extending along a main longitudinal axis, said tubular body defining at ] least one internal lumen suitable for receiving at least one medical device, the tubular body further defining at least one proximal opening and one distal opening. The tubular body includes a distal portion preformed in such a way as to take on a curved configuration with regard to the main axis. At least the distal portion of the tubular body has a flattened shape that extends prevalently along a main transversal axis, the curvature of said distal portion being created around said main transversal axis.
(1) Surgical and medical apparatus and instruments, namely, catheters, permanent metal prostheses for treating obstruction of the peripheral arteries (peripheral stents) and of the coronary arteries (coronary stents), angioplasty catheters and stents.
Surgical, medical, dental and veterinary apparatus and instruments, in particular catheters, medical devices, including permanent metal prostheses for treating obstruction of the peripheral arteries (peripheral stents) and of the coronary arteries (coronary stents), angioplasty catheteters and/or stents; artificial limbs, eyes and teeth; orthopedic articles; suture materials.
An endoluminal prosthesis, comprising a tubular body, said tubular body developing along a longitudinal axis, said tubular body comprising a plurality of serpentines, which develop along a substantially circumferential direction, each of said serpentines comprising arm portions of a preset width transversal to their main longitudinal extension, and bend portions joining two subsequent arms, at least one bridge, having a main longitudinal extension, connecting two adjacent serpentines, wherein the bends facing an adjacent serpentine are circumferentially staggered relative to the opposite bends of the adjoining serpentine, both when the prosthesis is collapsed and when the prosthesis is expanded or partially expanded, wherein the at least one bridge connecting adjacent serpentines extends substantially straight, and wherein the at least one bridge has a width transversal to its main longitudinal direction of a greater value than the arm width.
The present invention relates to a balloon (1) for treating stenosis and the method for obtaining this balloon. The method comprises the steps of : bringing the balloon in the deployed configuration; placing a plurality of stylets (17) that are arranged in the axial direction along the outer wall (10) of the balloon; pushing the stylets towards the balloon core (11) in the radial direction such as to form a plurality of laps (12); laying the laps about the core in the tangential direction such as to lay each lap on an adjacent stylet; removing the stylets such as to form a plurality of cavities (13) comprised between each lap and the balloon core; filling the cavities with the drug.
