Abstract: A device for occluding a patient's left atrial appendage (LAA) device includes a self-expanding closure disc and an anchor. The self-expanding closure disc has an atrial side, an appendage side, and a peripheral edge configured to engage tissue on both an atrial side and an appendage side of an opening between the left atrium and the left atrial appendage. The self-expanding anchor extends from the appendage side of the self-expanding closure disc, and an annular sealing skirt extends about at least a portion of the appendage side of the self-expanding closure disc. the annular sealing skirt is more compliant than the self-expanding closure disc to seal over the left appendage side of the opening after implantation of the device in the LAA.

Abstract: The present invention relates to a medical implantable interatrial septal defect occlusion device to occlude the congenital cardiac malformations such as Atrial Septal Defect (ASD) and Patent Foramen Ovale (PFO) providing hemodynamics between two atria. The occlusion device includes distal and proximal discs having expandable shape memory characteristics, pre-created sealed potential fenestrations which are sealed with biocompatible polymeric patch and sutures to be perforated and used for any possible intervention needed.

Abstract: An endolumenal medical device assembly is provided for use in a bifurcation region of a body lumen. An expandable prosthesis, preferably an endolumenal support device such as a stent, is included in the assembly and is adjustable from a radially collapsed condition to a radially expanded condition. The expandable prosthesis further includes a prosthesis passageway and a side port through which the prosthesis passageway communicates externally of the prosthesis. A dilator or an access device is engaged within the prosthesis passageway and also through the side port while the expandable prosthesis is in the radially collapsed condition.

The expandable prosthesis includes a prosthesis passageway and a side port. A dilator or an access device is engaged within the prosthesis passageway and also through the side port while the expandable prosthesis is in the radially collapsed condition. The expandable prosthesis may be positioned in the bifurcation region such that its distal end portion is in a first branch lumen extending from the bifurcation, its proximal end portion is in a common proximal lumen of the bifurcation region, and the side port is aligned with an entrance zone to a second branch lumen extending from the bifurcation.

Abstract: A fluid-actuated cylinder and a method for manufacturing it, including a head and a connecting tube to be coupled; coupling is obtained by compression of the two members along their axis, deforming the end of the tube by using, as a die for the deformation of the tube, a particular ring which is fitted on the head member and is coaxial thereto.

Abstract: Improved creasing machine, particularly for use in industry of cardboard articles and packages, comprising a sliding creasing roller and a fixed or stationary counter-roller, wherein the creasing roller is driven by the pistons of pneumatic, hydraulic or fluid-dynamic cylinders having the same axis of translation but different stroke.

Abstract: A flyback generator for a television receiver, in a sweep system driving the vertical-deflection yoke of a cathode-ray tube, comprises a storage capacitor with a low-voltage side grounded through a charging transistor and a high-voltage side connected through an isolating diode to the live terminal of a d-c supply. The charging transistor conducts during scanning but is cut off during flyback by the operation of a first switching transistor while a second switching transistor connects the low-voltage side of the charged storage capacitor to the live supply terminal whereby its high-voltage side is carried to a voltage V.sub.f equaling twice the supply voltage V.sub.s, less any voltage drop across the charging transistor. This high-voltage side is connected to the yoke through an output stage of a power amplifier saturated during flyback.

Abstract: For the periodic suppression of the beam of a cathode-ray tube in a television receiver during flyback, in response to a blanking pulse V.sub.2 normally accompanied by a flyback pulse V.sub.1 of shorter duration, a control transistor T.sub.11 is saturated to render conductive a master transistor T.sub.7 in series therewith, together with several slave transistors T.sub.6, T.sub.8 and T.sub.13 forming current mirrors with transistor T.sub.7. Slave transistor T.sub.13 lies in series with a Zener diode DZ across which the beam-suppressing signal V.sub.3 is generated; slave transistor T.sub.6 activates a comparator CMP having an input A connected to a biasing circuit PL1 including slave transistor T.sub.8. Another input B of the comparator receives from a voltage divider PL2 a biasing voltage of such magnitude that an output C of the comparator feeds back a holding signal to another control transistor T.sub.12, in parallel with transistor T.sub.11, to maintain the conduction of master transistor T.sub.
