Abstract: An analyte monitoring system includes a biosensor for detecting an analyt e concentration in blood. The monitoring system includes a sensor for sensin g whether a tool or other piece of equipment is producing electrical noise t hat may affect operation of the biosensor. If such electrical noise is detec ted, the system isolates the biosensor during the period of detected operati on of the other tool or equipment. In some embodiments, the system measures both signal noise in and temperature of the environment surrounding the bios ensor to determine whether another tool or other piece of equipment is curre ntly in operation. The system may also include an auxiliary power source to maintain the biosensor in a biased state during the period when the biosenso r is placed in isolation.

Abstract: A multiple lumen access device for use in providing a single entry port into the human body for selectively introducing medical implements therethrough and for providing simultaneous auxiliary access into the body. The multiple lumen access device (10, 400, 500, 520, 550) includes a multiple lumen sheath (404, 506, 530) which may have an outer tube (12, 422) and structure defining a device lumen (30, 31, 130, 230, 330, 426, 574, 582, 586) located therein. The inner structure may be an inner tube (24, 124, 224, 324, 432). The outer tube and inner structure are located so as to define at least one auxiliary lumen (36, 37, 48, 49, 138, 140, 142, 236, 248, 336, 428, 584, 588) which may be located between the exterior surface of the inner tube and the interior surface of the outer tube. Embodiments include flexible inner tubes which can be flexed between relaxed and expanded/contracted positions wherein the relative cross-sectional areas of the device lumen and auxiliary lumens are varied. The access device further includes a valve (70, 418, 502, 514, 528, 532, 554) which provides sealing of the device lumen. The valve may be provided in a lumen junction housing (56, 402), or separate from the housing either permanently or removably connected with the device lumen. Alternatively, a multiple lumen sheath (560) may be passed through a valve (554) leading to a conventional introducer (564). The valve may also be molded separately as a rigid insert (418) and retained in a cavity (450) formed in a flexible junction housing.

Abstract: A multiple lumen access device for use in providing a single entry port into the human body for selectively introducing medical implements therethrough and for providing simultaneous auxiliary access into the body. The multiple lumen access device includes a multi-lumen sheath which may have an outer tube and structure defining a device lumen located therein. The inner structure may be an inner wall or inner tube. The outer tube and inner structure are located so as to define at least one auxiliary lumen. Some embodiments include flexible inner walls which can be flexed between relaxed and expanded/contracted positions wherein the relative cross-sectional areas of the device lumen and auxiliary lumens are varied. The access device further includes a valve which provides sealing of the device lumen. The valve may be provided in a lumen junction housing or separate from the housing either permanently or removably connected with the device lumen. Alternatively, a multi-lumen sheath may be passed through a valve leading to a conventional introducer. The valve may also be molded separately as a rigid insert and retained in a cavity formed in a flexible junction housing. In other embodiments, the multiple lumen access device is formed by introduction of the elongated implement coaxially within a tubular single lumen sheath.
