IPC: A61B17/00
Filed: 1999-04-30
Abstract: Ce cathéter, à région distale préformée aux fins du positionnement de plusieurs électrodes au niveau d'un site biologique sélectionné, comporte une gaine à extrémité distale à courbure préformée de manière à répartir des forces axiales appliquées, dans le sens distal, au-dessus de la région distale sur une zone proche de la pointe distale. Ce cathéter comporte également un stylet fait d'un matériau à mémoire de forme et dont l'extrémité distale a une courbure préformée, de préférence, de 45· environ. Les forces axiales s'exerçant sur le cathéter sont déviées de manière à cintrer le cathéter dont une plus grande surface pourra alors venir au contact du tissu, bien mieux qu'il n'en serait avec la surface plus petite de sa pointe distale. Selon d'autres aspects de l'invention, la partie de la gaine correspondant à la courbure préformée est d'une dureté inférieure mesurée au duromètre, le stylet est plus souple du fait de son diamètre réduit et les électrodes se trouvent à proximité de la courbure préformée.

Patent CA-2344839-A1 (CA)
Inventor: LAROIA RAJIV
IPC: H04L12/28
Filed: 2001-04-23
Abstract: Access request transmissions are effected in a wireless communications system by assigning each mobile unit a unique dedicated uplink resource. Specifically, each mobile unit is assigned channel segments with distinct time slot indices and/or waveform indices, where waveforms with distinct indices are orthogonal. A base station can identify the mobile that has made an access request from the dedicated uplink resource. Therefore, no mobile identification number is needed in the uplink request message. Then, the base station can transmit a request response message on a shared downlink resource that may include the identification number of the requesting mobile unit to acknowledge reception of the request. The mobile unit may transmit on a shared uplink resource an acknowledgment of reception of the downlink request response message.
