Embodiment Construction

[0069] Figure 1-4 Illustrated is a divider member 10 embodying features of the present invention and comprising a divider membrane 11 ; a hub 12 preferably centrally located in the divider device; and a radially expandable reinforcement frame formed by a plurality of ribs 14 13. This embodiment of the partition member 10 may alternatively be referred to as an in vivo partition member or an in vivo product, both with respect to its position within the ventricle, and with respect to its function of separating the ventricle. Preferably, as figure 1 Separator membrane 11 is secured to the proximal or pressure side of frame 13 as shown. The rib 14 of the in vivo device has a distal end 15 secured to the hub 12 and a free proximal end 16 configured to bend or flare away from a centerline axis 17 . Radial expansion of the free proximal end 16 spreads the membrane 11 secured to the frame 13 such that the membrane presents a relatively smooth pressure receiving surface 18 partially...

Abstract

Described herein are systems and methods for securing a polymeric sheet to rib components of a frame structure, wherein the rib components are jointed at a hub to form an expandable and collapsible implant. In general, the method may include the steps of decreasing a diameter of the frame structure; placing the frame structure into an assembly fixture, wherein the assembly fixture is configured to hold the frame structure in a loaded configuration with a decreased diameter; placing a polymeric sheet into the assembly fixture; and heating the assembly under pressure to fuse the sheet to the frame structure. In general, a fixture may include a first and second platen having a shaping portion and a rim portion positioned around the periphery of the platen, wherein the shaping portions are configured to hold the rib components of the frame structure in a loaded configuration with a decreased diameter.
