Systems and methods for aiding users in viewing, assessing and analyzing images, especially images of lumens and medical devices contained within the lumens. Systems and methods for interacting with images of lumens and medical devices, for example through a graphical user interface.

Apparatus and methods are provided for flaring a stent deployed within a branch vessel including an ostium communicating with a main vessel, a first end of the stent extending at least partially from the branch. A catheter is provided that includes a balloon having a reinforced region adjacent an unreinforced region. When the balloon is positioned at a desired location, e.g., within a stent, prosthetic valve, or other tubular prosthesis, the balloon may be inflated to a first pressure causing the reinforced and unreinforced regions to expand substantially simultaneously. Upon inflation of the balloon beyond the first pressure, the reinforced region of the balloon remains at the first diameter and the unreinforced region continues to expand, e.g., to flare one or more ends of the prosthesis.

A horseshoe-shaped guide catheter for stent angioplasty of the ductus arteriosus in newborn and infants with ductal-dependent cardiopathies, characterized by a long, straight, hollow first section merged at the distal end thereof to a second section formed by a curved portion shaped as a circle section with radius (Ra) of 7.5 mm to 9 mm, arc (b) of 180° to 280° and distance (d) between the tip of the second section and the straight part of the first section without deformations of 7 mm and 15 mm. The angioplasty makes it possible to insert one or more stents that keep the ductus open in extrauterine life, improving survival of the newborn and young infants, allowing weight gain and undergo corrective surgery a few months later with safer and with better outcomes.

A system of prosthetic implants for a total knee replacement procedure is provided. The system includes a tibial component of a knee joint implant, a tibial insert configured to be positioned against the superior side of the platform of the tibial component, a first femoral component of a knee joint implant, and a second femoral component of a knee joint implant.

In a method for producing an implant from a biocompatible silicone, a 3D mathematical model of an implant to be produced is used to create a 3D model of a casting mold for the implant as a negative. The casting mold is produced from a polymeric material through an additive manufacturing process and coated through vapor deposition of a coating material from the parylene family at least in a region that comes into contact with the biocompatible silicone to be cast. A platinum-catalyzed 2-component thermosetting silicone as the biocompatible silicone for the implant is introduced into a mold cavity of the coated casting mold, with a residence time of the implant in a patient's body of more than 29 days. The casting mold is heated to vulcanize the biocompatible silicone, and after cooling down the vulcanized implant is demolded from the casting mold.

A pulmonary artery flow restrictor system includes a funnel shaped membrane with a proximal base, a restrictive distal opening which is stretchable to larger sizes, an internal strut structure, and an external stent structure.

A method of manufacturing a covered stent is disclosed. The method includes winding a first PTFE tape around a cylinder body of a jig, winding a second PTFE tape around a stent including the jig fitted therein, heating the stent in an oven, fitting the stent into upper and lower elastic members, fitting the elastic members into a mold, pressing the upper elastic member to bond the PTFE tapes to each other and to thus form a first film at a cylindrical body of the stent, taking the elastic members out of the mold, taking the stent out of the elastic members, removing the jig from the stent, forming a silicone coating layer at an expansion portion of the stent, and sewing the spaces in the expansion portion, the second PTFE tape, and the silicone coating layer to form a second film at the expansion portion.
