Abstract: A novel stent compression instrument is used for holding a stent therein during shipping to a hospital and for thereafter crimping the stent onto a balloon catheter. The stent compression instrument includes a body having a central bore; a flexible diaphragm having an axial lumen and mounted within the body central bore, thereby defining a chamber between the body and the diaphragm, and first and second sealing structures for providing seals at opposite ends of the chamber. The diaphragm is formed from a generally tubular, thin wall into which the stent is placed therein and is expandable under a negative pressure condition to expand within the body and compressible under pressure to crimp the stent onto a balloon catheter.

Abstract: In accordance with the present invention, a fluid compression instrument and method for particular use in pre-surgically securing and conforming a vascular stent upon an angioplasty balloon, includes a housing for containing pressurized fluid and an elastic enclosing diaphragm secured within the housing and having an internal cavity and opening arranged to receive the stent disposed on the balloon catheter for secured compression. A pressure chamber is arranged within the housing as an envelope about the diaphragm to enable pressurized fluid forces within the pressure chamber to be imposed upon the outer surface of the diaphragm and transmitted through the diaphragm enabling circumferential application against the inserted stent in order uniformly to compress the stent with correspondingly secured purchase against the deflated balloon surface, producing complete adhesion of the stent thereon.

Abstract: A coagulation timer device is used to monitor the bleeding time of a patient to determine the amount of time required to achieve clotting. The coagulation timer device includes a carrier member, a linearly oriented absorbing medium which is affixed to the carrier member and a bag member which overlays the carrier member and the medium. The medium, such as filter paper or the like, is used to blot blood from an incision which has been formed through the skin. The medium is affixed to the carrier member and includes a plurality of segments each of which are defined by a scalloped edge portion which extends beyond the edges of the carrier member. The segments are used one at a time at predetermined intervals to blot the blood by touching the scalloped edge to the blood.

Abstract: A percutaneous vaccine applicator system which includes a percutaneous vaccine applicator and a packaging assembly for housing the vaccine applicator. The percutaneous vaccine applicator includes a handle and spiked portion attached to the handle. A plurality of spikes project from the spiked portion for puncturing the skin of a patient to deliver a percutaneous vaccine. The packaging assembly includes a hollow container and a removable cover attached to the container. The hollow container defines a cavity being sized and dimensioned for receiving the vaccine applicator. The container has structures for positively receiving and retaining an applicator placed therein.

Abstract: A medical alert pendant for use as a wireless remote actuation device in an emergency alarm system or the like includes a housing with a circuit board assembly and a resilient mounting and sealing membrane mounted therein. The housing includes an upper housing section which has an opening in the surface thereof, and a lower housing section. The circuit board assembly includes a power source, a signal transmitter and a depressible switch which activates the transmitter. The membrane is positioned between the housing sections and includes a flexible button which is disposed in the housing opening and juxtaposed to the switch on the circuit board assembly. The depression of the flexible button will operate the switch on the circuit board. The membrane includes a first peripheral seal which seals the juncture between the housing sections and a secondary seal which seals the opening in the upper housing section.

Abstract: A liquid dispensing nozzle assembly is provided for mounting on a liquid container and dispenser having a flexible wall and liquid storage cavity for manually squeezed dispensing of a liquid from the cavity through the nozzle assembly. The nozzle assembly maintains the liquid, such as contact lens saline solution, in sterile condition during storage and repeated dispensing of the liquid from the container cavity. The nozzle assembly includes a liquid conduit for communication from the container cavity to a liquid discharge port from the nozzle assembly to enable dispensing of the liquid displaced by manually squeezing the flexible wall of the container. The nozzle assembly also includes an air aspiration conduit separate from the liquid conduit for aspirating air into the container cavity to replace the dispensed liquid. The nozzle assembly includes a partitioned diaphragm including separate portions respectively included in the liquid conduit and the air aspiration conduit.

Abstract: The present invention provides an actuator mechanism for sequentially advancing and retracting a lancet needle and includes a drive carriage for advancing and retracting the lancet needle and a hinge structure operatively connected to displace the drive carriage. The hinge structure includes first and second coupled leaf members relatively pivotal between a first position thereof in which the drive carriage is advanced to project and thrust the lancet needle into a tissue penetration position, and the second pivotal position of the leaf members in which the drive carriage is retracted to withdraw the lancet needle from the penetration position. The leaf members can also be pivotal to a third position in which the drive carriage is retracted prior to initiating the advancement so that the first position of the leaf members is pivotally intermediate between the second and third relative positions thereof.

Abstract: An appliance for disinfecting contact lenses wherein the lenses are disposed within a lens disinfecting solution which produces a gas during the disinfecting action. The appliance has a container body with a lens holder for supporting a pair of contact lenses within the container and a removable cap with a vent means which seals the container to prevent contamination while permitting the venting of gases developed during the disinfecting action. The vent consists of a post positioned in a bore such that the post does not obstruct passage of gas from the inside of the container through the bore and a resiliently deflectable apertured diaphragm through which the post protrudes. The aperture in the diaphragm deflects away from the post when the pressure within the container exceeds a threshold pressure. Once the pressure within the container is equalized with the ambience, the diaphragm resiliently deflects to close the vent thereby protecting the contents of the container from contamination.
