Patent number: 10874770Abstract: The present invention relates to a drug-eluting medical device, in particular a balloon for angioplasty catheters with drug elution to prevent the restenosis of the vessel subjected to angioplasty. More particularly, the present invention relates to a catheter balloon completely or partially coated with paclitaxel in hydrated crystalline form or in hydrated solvated crystalline form, having an immediate release and bioavailability of a therapeutically effective amount of paclitaxel at the site of intervention. The balloon can be made of a polyether-polyamide block copolymer, or a polyester amide, or polyamide-12.Type: GrantFiled: March 19, 2020Date of Patent: December 29, 2020Assignee: INVATEC TECHNOLOGY CENTER GMBHInventors: Ulrich Speck, Silvio Schaffner, Magdalena Renke-Gluszko

Patent number: 9168362Abstract: A drug eluting angioplasty balloon (1, 101) suitable to adopt a deployed configuration and a collapsed configuration, the balloon having an outer wall (10) disposed around a core (11) defining an axis (X). The balloon (1, 101) comprising in the collapsed configuration a plurality of folds (12, 12?, 112) that are laid in a tangential direction about the core (11) and form a plurality of cavities (13a, 13b, 113) loaded with a drug (14), the cavities (13a, 13b, 113) are comprised between the folds (12, 12?, 112), wherein the folds (12, 12?, 112) originates from distinct longitudinal lines (25, 25?, 125, 125?) along the outer wall (10), are arranged in pairs and are circumferentially wrapped about the core (11) in such a way that a fold of one pair overlaps an adjacent fold of another pair and are wrapped in opposite directions.Type: GrantFiled: December 21, 2010Date of Patent: October 27, 2015Assignee: Invatec Technology Center GmbhInventors: Massimo Morero, Giovanni Scalvini

Publication number: 20100274348Abstract: The present invention relates to an assembly (10) comprising at least a first stent (1?) and a second stent (1?). Each stent comprises a proximal section (2), a central section (3), and a distal section (4). The proximal and distal sections provide a radial force which is essentially equal to a half of the radial force which is provided by the central section. Thus, by overlapping the distal section (4?) of the second stent (1?) to the proximal section (2?) of the first stent (1?), the radial force which is provided by the overlapped sections is nearly equal to the radial force which is provided by the central sections (3?, 3?) of the two stents.Type: ApplicationFiled: December 19, 2007Publication date: October 28, 2010Applicant: Invatec Technology Center GmbHInventors: Silvio Schaffner, Thomas Bauer
