Title: Aparato y metodos de ancla distal para la reparación de la valvula mitral
Inventor: ETHERIDGE JULIE MARIE
IPC: A61F2/24
Filed: 2018-04-06
Abstract: Described herein are devices and methods for mitral valve repair. The devices and methods implant a plurality of distal anchors at an annulus of the mitral valve (e.g., the posterior annulus) and tension artificial chordae to pull the portion of the annulus toward an opposite edge and inward into the ventricle. This can effectively reduce the size of the orifice and increase coaptation. The anchor points of the artificial chordae can be offset from the apex of the heart to achieve a targeted force vector on the annulus. In addition, some embodiments include distal anchors implanted in the posterior leaflet in addition to those at the posterior annulus. This allows differential tensioning to be applied to provide for greater flexibility in treating various configurations of mitral valves to improve coaptation.

Abstract: 1,015,005. Vibratory mechanisms. INSITUT FRANCAIS DU PETROLE, DES CARBURANTS ET LUBRIFIANTS and COMPAGANIE GENERALE DE GEOPHYSIQUE. Nov. 1, 1963 [Nov. 3, 1962], No. 43293/63. Heading F2X. A vibrator, e.g. for seismic prospecting, comprises a pulsing plate P and a vertically movable heavy upper plate M separated by at least two wedge elements C having a wedge angle of less than 45 degrees and upper and lower faces parallel to adjacent faces of the plates P, M, each wedge element C being solid with a movable part B of an associated oscillator for reciprocation therewith, the movable parts B being moved synchronously, relative to a fixed part A common to all the oscillators, in such directions that the resultant of the horizontal components of the forces exerted thereby is zero. The oscillators, which may be electromagnetic, hydraulic, pneumatic or mechanical, may be mounted on the plate M or the plate P, or may float in the space between the two plates. The wedge surfaces adjacent the plate to which the oscillators are fixed must be parallel to the direction of motion of the moving parts B. The plates P, M may bear directly on the wedge elements, or rollers G 1 , G 2  may be interposed. Adjustable tension or compression springs acting horizontally or vertically, e.g. as at R, urge the wedge elements towards their median positions to prevent the plate M from forcing the wedges to an extreme position. The resonant frequency of the resulting assembly should be substantially lower than the working frequency of the vibrator.

Abstract: 1,050,196. Time division multiplex systems. STANDARD TELEPHONES & CABLES Ltd. Nov. 13, 1964 [Nov. 20, 1963], No. 46305/64. Headings H4K, H4L and H4R. Resonant transfer circuits, for use in pulse amplitude modulation arrangements and time division multiplex telephone exchange systems, particularly where the resonant transfer circuits include amplifiers, include filters so designed that their cut-off frequencies are distinct from half the sampling frequency and at least one of which has a pulse impedance which is purely resistive and constant at frequencies inside and outside the pass band. The pulse impedance requirement may be met by associating with one of the filters a compensating filter with a pulse impedance that compensates the variations of the pulse impedance of the uncompensated filter. Preferably the pulse impedances of the uncompensated filter and the compensating filter change gradually from one value in the pass band to another value outside the pass band so that tolerances causing departures from ideal conditions do not cause substantial departures from the desired characteristics. Fig. 1 shows a general resonant transfer circuit having switches S1 and S2 to effect transfer of energy between a source E and a load R2. The network NO may include in its simplest form for direct resonant transfer without storage, a single series inductance in which case the switches S1 and S2 are operated synchronously. If intermediate storage is used the switches are operated at different times and the network will include additional reactive storage elements and additional switches and may also contain negative impedance circuits to provide amplification. Fig. 18 shows the way in which the filter N 1  may be made up of the normal low pass or band pass filter N1A with the compensating filter N1B in series to compensate the variation of pulse impedance of the filter N1A. and Figs. 24, 25 and 26 show various embodiments of compensating filters. The circuit is mathematically analysed and stability criteria evaluated in a manner analogous to the theory of feedback amplifiers using Nyquist's diagrams.

The extrudate may be cut by a reciprocating knife (69), Fig. 4 (not shown), to give an openended product, or by rotary cutters (32, 33), Figs. 1a, 1b, 1c (not shown), as described in Specification 1,154,074, to give closed-ended products, see Figs. 6-8 (not reproduced). The severed extrudate is removed on conveyer (38), Fig. 1a (not shown). In a second embodiment, Fig. 12 (not shown), separate holders for the mandrel and outer die part are dispensed with.
