Abstract: L'invention concerne un anneau pour annuloplastie pouvant être agrandi qui peut soit s'agrandir de manière spontanée in situ, alors que le patient grandit, soit être agrandi par une intervention chirurgicale par dilatation d'un ballonnet. L'anneau pour annuloplastie pouvant être agrandi peut être utilisé chez les patients en pédiatrie dont la croissance, suite à un implant chirurgical de l'anneau, va imposer un agrandissement ultérieur de l'anneau afin qu'il s'adapte à la croissance de l'anulus. L'anneau peut comprendre des segments relativement agrandissables permettant son agrandissement. Les segments de l'anneau peuvent comprendre des dents de couplage qui coopèrent avec des entailles ou des fentes formées dans les tubes pour assurer une certaine résistance à la distension de l'anneau, tout en évitant l'affaissement de l'anneau dans le sens opposé. La dent peut présenter différentes dimensions ou formes permettant de réguler la quantité de force nécessaire à l'agrandissement de l'anulus à différentes étapes de la croissance du patient. Selon une autre variante, l'anneau réglable comprend une âme solide de matière non élastique qui maintient sa forme au moment de l'agrandissement naturel de l'anulus ou après un agrandissement chirurgical. Selon un mode de réalisation, les segments sont assemblés de manière discontinue autour de la périphérie de l'anneau. Des zones d'articulation sont prévues entre les segments adjacents qui, tout au long de la discontinuité, permettent à l'anneau de s'agrandir en fonction de la croissance de l'anulus. La discontinuité peut longer le côté antérieur de l'anneau ou se trouver autour côté postérieur. Selon une autre variante, on utilise des segments télescopés sans discontinuité. Les segments sont assemblés à l'aide de gaines tubulaires et s'agrandissent sans se désassembler. Il n'est pas nécessaire d'avoir recours à un revêtement en tissu.

Title: Ostomy coupling
Inventor: WHATLEY IAN
IPC: A61F5/448
Filed: 2000-12-13
Granted: 2010-02-23
Abstract: An ostomy coupling is described of the type comprising a locking member in the form of a resilient split ring, for fastening two ostomy coupling members together. One feature of the invention is that one of the coupling members comprises a tapered seal seat surface for cooperating with a deflectable seal wing carried by the other member. The tapered seal seat has a smoothly curved taper, to enable a relatively large seal area to be provided within a low coupling profile height. Another feature of one form of the invention is that the split ring has an inclined outer surface to form a smooth profile with the coupling member on which it is carried. Another feature of another form of the invention is that each limb of the split ring is bifurcated to receive a radially projecting guide of the coupling member, on which the split ring is mounted. The split ring thus extends above and below the guide, removing the need for a mounting channel on the coupling member itself, and enabling the height of the coupling to be further reduced.

Title: Watertight battery compartment cover with latch actuated o-ring seal
Inventor: LAWLESS MICHAEL W
IPC: H01M50/213
Filed: 1999-06-04
Granted: 2008-03-25
Abstract: A cover for a battery compartment in a medical device such as an ambulatory pump that is used for infusing a medicinal fluid. The battery compartment cover includes a lever (18) that is pivotal between an open and a closed position. The lever is connected to a plunger (22) that applies a compressive force against an O-ring, which is trapped between a shoulder on a washer through which the plunger extends and an end of the plunger. When the lever is pivoted to its open position, the compressive force on the O-ring is released, enabling the battery compartment cover to be removed from the opening into the battery compartment. However, when the lever is pivoted to its closed position, it draws the plunger outwardly, applying a compressive force to the O-ring that causes the O-ring to expand radially outward, sealing the opening into the battery compartment against the intrusion of water or other liquids and securing the battery compartment cover in engagement with the opening.
