Abstract: An intrauterine device includes an elongate member; and a flexible arm having a first end and a second end, wherein the first end is operatively coupled to the elongate member at a first location, and wherein the second end is operatively coupled to the elongate member at a second location, and wherein the flexible arm is adjustable between a closed configuration, in which the flexible arm is closely apposed to the elongate member, and an open configuration, in which the flexible arm extends away from the elongate member, and wherein the flexible arm is biased to be in the closed configuration.

Abstract: Devices and methods are disclosed for the delivery of an implant into small bodily spaces. The delivery devices include an expandable portion configured for placement within such bodily spaces and subsequent expansion to facilitate the delivery of the implant.

Abstract: An implant configured for insertion and placement within a fallopian tube of a female during a sterilization procedure. The implant includes an implant body having proximal and distal ends and a tether. The tether is attached to the implant body and extends a distance away from the implant body. The tether may be bioabsorbable and/or detachably coupled to the implant body so that the tether can be separated from the implant body without dislodging the implant body from the fallopian tube.

Abstract: Sterilization devices and methods for deploying porous implants within the fallopian tubes are disclosed. The devices include a catheter component including an external electrode sheath containing at least two deployable implants and a positioning member. Sliding the external sheath proximally disposes the implants within the fallopian tubes, while sliding both the positioning member and external electrode sheath distally reloads a second implant into the external electrode sheath. The devices further includes a handle component, which houses a chassis, external electrode sheath carrier, reciprocating shaft, positioning member carrier and first and second engaging members. The reciprocating shaft may be operated by a motor to slide distally and proximally along a long axis. The reciprocating shaft, external electrode sheath and its carrier, upon selective actuation, move together proportionally to deploy and reload the implants to facilitate occlusion of the fallopian tubes and complete sterilization.

Abstract: This invention relates to a continuous process for preparing perylenes by (a) continuously mixing a melt of the leuco form of a perylene tetracarboxylic diimide obtained by alkaline fusion of naphthalimide with a continuous water-containing stream containing (1) 2 to 50 parts of water per part of melt, (2) 0 to X1 moles of oxidizing agent per mole of the leuco form, (3) 0 to Y1 parts by weight of processing additives, based on the leuco form, and (4) 0 to Z1 parts by weight of an acid, based on the leuco form of the perylene tetracarboxylic diimide, to form a slurry; and (b) optionally mixing the slurry in one or more continuous or batchwise steps with a second stream containing (1) 0 to 10 parts by weight of water, based on the slurry, (2) 0 to X2 moles of oxidizing agent per mole of the leuco form of the perylene tetracarboxylic diimide, with the proviso the total of X1 and X2 represents at least the molar amount of oxidizing agent theoretically needed to oxidize all of the leuco form of the perylene tetr

Abstract: This invention relates to a continuous process for the preparation of quinacridone pigments by(a) preparing a reaction mixture by mixing(i) a 2,5-dianilinoterephthalic acid or ester thereof, and(ii) at least about 0.5 parts by weight, per part of component (a)(i), of a dehydrating agent;(b) passing the reaction mixture through a continuous reactor having one or more heated zones at a temperature of about 80.degree. C. to about 300.degree. C. to form a crude quinacridone composition; and(c) mixing a continuous stream of the crude quinacridone composition with a liquid in which the quinacridone pigment is substantially insoluble at a ratio of about 0.5 to about 15 parts by weight of the liquid per part by weight of the crude quinacridone composition.

Abstract: This invention relates to a process for removing copper ions from highly acidic waste water generated during the manufacture of dyes or pigments or intermediates thereof. The waste water is exposed at a pH less than about 1 to a bed of suspended iron particles, preferably a fluidized bed of iron particles, having a particle size of from about 200 to about 950 micrometers.
