Title: Implantable blood pump
Inventor: POL VINCENT
IPC: A61M60/894
Filed: 1984-11-26
Granted: 1987-08-20
Abstract: Inside a flexible shell (10), a deformable pocket (20) is connected to blood circulation via an inlet valve (30) and an outlet valve (40). The pocket is compressed by a floating assembly comprising a drum (50), and a bracket (60) rotatable about the axis thereof. One of the edges (21) of the pocket (20) is fixed to the drum (50); the opposite edge (22) is connected to the bracket (60) by a traction link (70), for example an inextensible sheet. Relative rotation between the drum and the bracket over a fraction of a turn enables the pocket (20) to be wrapped around the drum (50) and the assembly returns to its starting position under the effect of venous pressure. The disposition of the various components provides a self-adapting lever which limits mechanical losses to rolling friction between the drum and the pocket.

Title: Continuous method for elasticizing discrete articles cut from a moving web in a direction perpendicular to web travel
Inventor: CHAPMAN L RICHARD
IPC: A61F13/494
Filed: 1984-03-14
Granted: 1988-08-11
Abstract: A continuous, high speed method for elasticizing articles such as disposable diapers, incontinent briefs, and the like by securing an elastically contractible element to a moving, interconnected web of said articles, said elastically contractible element causing the discrete articles cut from the web to shirr in a direction substantially perpendicular to the direction of web travel. Prior to application and securement, the web from which the elastically contractible elements are cut is laterally stretched while at an elevated temperature which is less than its crystalline melting temperature and allowed to cool to ambient temperature. This molecularly orients the elastomeric material and makes the web dimensionally heat unstable parallel to the direction of stretching. The elastically contractible element is cut from the web of the heat unstable elastomeric material so that the length of the element coincides with the width of the heat unstable web. The elastically contractible element is applied to the moving web of interconnected articles while in a substantially untensioned, molecularly oriented, dimensionally heat unstable condition. The elastically contractible element is so oriented when applied to the web of interconnected articles that the direction of lateral stretching applied to the elastomeric web to impart a dimensionally heat unstable condition is aligned substantially perpendicular to the direction of travel of the web of interconnected articles. The discrete articles cut from the web are thereafter subjected to an external stimulus, such as heat, to cause the elastically contractible element to shrink and become dimensionally heat stable and elastic in a direction parallel to its length, thereby imparting shirring in a direction substantially perpendicular to the direction of web travel.
