A prosthetic mitral valve includes an anchor assembly, an annular strut frame, and a plurality of replacement leaflets secured to the annular strut frame. The anchor assembly includes a ventricular anchor, an atrial anchor, and a central portion therebetween. The annular strut frame is disposed radially within the anchor assembly. An atrial end of the annular strut frame is attached to the anchor assembly such that a ventricular end of the annular strut frame is spaced away from the anchor assembly.

Injection molding method and apparatus for ejecting a molded plastic preform from a mold. A first lifting structure and / or step is configured to have an inner surface with an area for sealing and aligning with a complementary surface on a core, and to have an upper surface with an area for sealing and aligning with a complementary surface on a second lifting structure, said upper surface of said first lifting structure being configured to lift a molded plastic preform from the injection mold in a lifting direction for a first period of time, the lower portion of the molded plastic preform lying in a plane substantially perpendicular to the lifting direction. A second lifting structure and / or step is configured to have an inner surface configured to lift an outer surface of the molded plastic preform from the injection mold in the lifting direction for a second period of time, the outer surface of the molded plastic preform including structure lying in a plane substantially parallel with the lifting direction.Since the molded plastic preform is lifted by its end, the preform does not have to be solidified at its interior, thus allowing earlier removal of the preform from the mold, reducing cycle time.

A mounting device for an optical element in an assembly has a support member 3 with two or more gear elements 1. The support member 3 is connected, on the one hand, to an external mounting structure 30 and, via base points 2, to the gear elements 1. Via top points, the gear elements 1 are connected to the optical element 5 directly, or are connected to the optical element 5 indirectly via a mount 5' arranged therebetween. The top points 4 of the gear elements 1 are located in planes of symmetry of the optical element 5 which are defined by the axial axis and a radial axis of the optical element 5. The gear elements 1 are arranged and dimensioned such that in the event of disturbing influences a compensation effect is produced with regard to the deformation of the optical surface of the optical element 5. The compensation effect is provided when the RMS value of the sum of those partial deformations of the optical surface of the optical element 5 which are caused by an axial force, a radial force and a tangential element at an arbitrary top point 4 of a gear element 1 is smaller by at least the factor 2 than the greatest RMS value of one of the three said partial deformations.

The end-effector (150) includes a sheath (152) and a medical device or needle carrier (154) that is disposed within the interior compartment (160) of the sheath. Aperture (162) is located in a portion of the sheath proximal a distal end of the sheath that is inserted into a natural or artificial cavity. This device is guided by a real-time imager.

A multilength tubular transporter is provided, comprising a base frame, including at least two main beams, wherein the main beams are connected by a plurality of cross members, a floor substantially covering the areas defined by the main beams and cross members; a plurality of substantially vertical guide members connected to each of the main beams; a lifting arrangement operatively connected to the base frame for enabling the transporter to be lifted to and from a vehicle; a stacking device operatively connected to the base frame for engaging the guide members of a second transporter, wherein the transporters may be securely stacked; and wherein the base frame includes one or more winches for securing tubulars within the transporter.
