Abstract: An apparatus for carrying out peritoneal dialysis includes a central manifold, a receptacle for waste dialysate, means for supporting and heating a plurality of fresh dialysate bags, a first conduit connecting the manifold with the patient catheter, a second conduit for connecting the manifold with the receptacle, and a plurality of additional conduits connecting the manifold individually with a plurality of fresh dialysate bags. The individual conduits can be selectively closed by clamping means controlled by an electronic control, and the latter has an automatic mode which cycles the apparatus through (a) a fill/dwell phase in which the contents of one of the fresh dialysate bags flows into the patient's peritoneum cavity by gravity and remains there, and (b) a drain phase which allows waste dialysate in the patient's  peritoneum cavity to drain by gravity into the receptacle.  The steps (a) and (b) are repeated for all of the bags until they have been used up.  A safety provision is provided to determine whether a sufficient quantity of dialysate has drained from the patient's cavity during the drain phase.  If not, the apparatus is shut down.

Abstract: A luminal stent is a tubular body formed by knitting a yarn of a bioresorbable polymer fiber, such as fiber of polylactic acid, polyglycol acid or a polylactic acid - polyglycol acid copolymer. When introduced into and attached to the inside of the vessel by a catheter fitted with a balloon, the tubular member may retain its shape for several weeks to several months after attachment and subsequently disappears by being absorbed into the living tissue. In this manner, the luminal stent is not left as a foreign matter semi-permanently in the living body without producing inflammation or hypertrophy in the vessel.      There is also provided a method for attaching the luminal stent in the vessel.

Granted: 1996-08-27
Abstract: This invention embodies p-n junction devices comprising Group III-V compound semiconductors in which the p or n or both p and n regions are formed by a superlattice selectively doped with an amphoteric Group IV element dopant selected from carbon, germanium and silicone. The superlattice includes a plurality of periods, each including two layers. Depending on the conductivity type, only one of the layers in the periods forming the superlattice region of said type of conductivity is selectively doped with said dopant, leaving the other layer in these periods undoped. The superlattice is formed by Molecular Beam Epitaxy technique,and the dopant is incorporated into respective layers by delta-doping as in a sheet centrally deposited between monolayers forming the respective layers of the period. Each period includes 5 to 15 monolayers deposited in the two layers in a numerical ratio corresponding to a cation compositional ratio in the compound semiconductor. Low growth temperatures, e.g. ranging from 410 to 450°C lead to mirror-like surfaces. For a compound semiconductor Ga0.47In0.53As, the GaAs/InAs ordered superlattices with eight monolayers per period are grown in a ratio of 0.47/0.53. At free carrier concentrations of 1016cm-3, carrier mobilities of 200 and 2300 cm2 /Vs for p-type and n-type are obtained with carbon as the amphoteric dopant.
