Abstract: An infusion catheter system which includes a generally cylindrical housing member having a passageway extending therethrough, a guiding catheter having a proximal end disposed at one end of the cylindrical housing member such that the passageway in the housing member communicates with a passage in the guiding catheter, and an infusion catheter slidably positioned within the passage of the guiding catheter. The catheter system also includes a manifold valve which is coupled to the housing member for applying a first fluid through the housing member to the passage of the guiding catheter, and a second manifold valve which is coupled to the infusion catheter for applying a second fluid through the passage of the infusion catheter. Typically, an anticoagulate fluid is applied through the guiding catheter to prevent blood clotting during an infusion procedure and a blood clot dissolving fluid, such as streptokinase, is applied through the infusion catheter. With this catheter infusion system, the distal end of the infusion catheter may be precisely positioned within an artery so that the clot dissolving fluid may be effectively administered.

Abstract: An adjustable nozzle assembly for a hand operated compression sprayer is disclosed. The nozzle is attached to the discharge end of the sprayer and is adjustable from an off position to two discharge positions, such as a spray position and a stream position. The nozzle and sprayer body have cooperating passages which, when brought into register by adjustment of the nozzle, determine the discharge mode (i.e., whether off, spray or stream).

Abstract: There is disclosed herein a catheter introducer having an axially disposed cylindrical elastic segment which covers first and second substantially solid cylindrical elements each defining internal and external diameters, each of said annular elements, as well as the elastic segment, disposed radially symmetrically about a common axis. Also provided are means for rotatably securing said first and second elements relative to said common longitudinal axis for facilitating a reduction in diameter of said elastic segment in order to perform a fluid-tight seal against any elongated element placed along and within said longitudinal axis. A catheter so introduced may be advanced, withdrawn, held, or otherwise manipulated without loss of the fluid or atmospheric seal between the internal diameter of the elastic segment and the object introduced.

Abstract: A child-resistant threaded closure for containers is presented which includes a lower ring-like portion attached to the closure by retractable and extendible legs and having a matching thread. With the closure screwed in place on a container, the ring is pushed down by means of tabs to a position below the last thread on the container with the legs extended whereupon, when an attempt is made to unscrew the closure, the thread segment of the ring interferes with the last thread of the container and prevents its removal. For the closure to be removed, the ring is lifted up by finger pressure applied to the tabs until the legs are fully retracted and the threads match up with the others after which action the closure can be unscrewed.

Abstract: A dispenser body and a closure cap assembly for a container is presented which provides not only a closure for the container, except for communication with the dispenser, but also provides an air inlet operable upon the withdrawal or expulsion of the contents of the container so that air will be replenished therein to restore normal air pressure. The air inlet closes automatically when this has been accomplished to prevent leakage of the contents of the container.
