Abstract: Transcatheter device for the treatment of calcified native heart valve leaflets comprising an outer hollow shaft (5), an inner hollow shaft (4) slidingly contained within said outer shaft (5) and an axle body (6) slidingly contained within said inner shaft (4); wherein the device comprises a commissure debridement system (7), located at the distal end of the axle body (6), that is made of at least two radially expandable arms (7) that are adapted to be inserted in and aligned with native commissures.

Abstract: A transcatheter temporary valve prosthesis for blood vessel comprising an expandable support structure (5?), a valve (7), a filter (12) and a conveyor (6); said support structure (5?) forming a tubular shape when expanded, with a distal and a proximal end, said valve (7) being located at said distal end and said conveyor (6) extending within said support structure (5), from said proximal to said distal end and including a central passage that is adapted to act as an introducer for other devices.

Abstract: An intra-vessel transcatheter filter device (1) designed to capture and remove emboli, thus preventing distal embolization, comprising: • a tubular filter (2) comprising a flexible porous material and defined by a distal element and a proximal element, namely a main body (3) and a funnel (4); i. said main body (3) having a length adapted to extend within a suitable vessel zone; said main body (3) comprising: a) a distal end (5) that is adapted to be radially coupled with said zone and hermetically sealed to it when the device is in an active configuration, said distal end (5) being provided of selectively actionable closure means so that said distal end is designed to be open when the device is in an active configuration and closed before the device retraction, b) a proximal end (6); ii. said funnel (4) forming an extension of said main body (3), with the funnel base located at said proximal end (6). • a support structure assembly (8) comprising: i.

Abstract: Device for the treatment of tissue calcification, in particular aortic valve leaflets, characterized by the fact that it comprises a first ultrasound emission source that is adapted to provide ultrasound waves with MHz frequencies and a second ultrasound emission source that is adapted to provide ultrasound waves with KHz frequencies, both MHz and KHz waves being used for the said treatment. The invention also includes a method for the treatment of tissue calcification that is characterized by the simultaneous use of ultrasound waves with MHz frequencies and ultrasound waves with KHz frequencies.

Abstract: An annuloplasty prosthesis having at least one inner support element of elastomeric material and an outer fabric covering the support element. The elastomeric material impregnates the facing portions of the covering fabric so that the support element is fixed firmly to the covering fabric, preventing relative sliding movements between the fabric and the support element.
