Abstract: A parenteral solution container having a dual use access port used for both the administration of fluids to a patient as well as for the addition of fluids to the container, includes a generally cylindrical wall with an axial passage therethrough. A fluid-tight sealing means, having a reseal member that includes a slit therein to enable the reseal member to be pierced with a blunt, metal cannula, or sharp needle is removably attached to the dual use access port. When the dual use access port is used in its fluid addition capacity, the reseal member is attached to the wall and a blunt cannula is passed through the reseal member. Once the blunt cannula has been completely inserted, fluids may be added to the container. To use the dual use access port in its administration capacity, the sealing means is completely removed from the wall. A piercing pin is inserted into the wall creating a fluid-tight seal so that fluids may be administered to a patient.
Abstract: A method and apparatus are provided for introducing molecules such as genes and pharmacological compounds into living blood cells of a patient for therapeutic purposes. A device is implanted into the body of the patient for generating an electric field at a preselected location within a selected blood vessel. Preselected molecules are infused into the selected blood vessel. Simultaneously an electric signal is applied to the implanted device to repeatedly subject a quantity of blood flowing within the selected blood vessel past the preselected location to electric fields of a predetermined amplitude and duration. The parameters of the electric fields are precisely controlled in order to make the walls of preselected cells in the blood transiently permeable to permit the molecules to enter said preselected cells without killing said cells. The device can include either a pair of electrodes implanted in the blood vessel, or alternatively, an induction coil that surrounds the blood vessel.
Abstract: An intraocular lens that includes an optical lens body and haptics extending outwardly from the optical lens, said haptics extending at about a zero degree of angulation with respect to the lens body when not under compression and at least one haptic having at least one segment which is formed so that upon compression of the haptics under conditions similar to implantation said at least one segment will create a torque which causes the lens to vault in only one predetermined direction and to a predetermined angulation greater than zero.
Abstract: A protective cover (16) for covering a blood-pressure cuff (10) comprises a flexible sheet defining an elongated bottom band (24), an elongated top band (30), and an intermediate portion (38) interconnecting the bottom and top bands. The bottom and top bands have widths which are substantially greater than a width of the blood-pressure cuff. A length of the bottom band is greater than a distance about an appendage (14) about which the blood-pressure cuff is to be wrapped and a length of the top band is greater than a distance about an outer surface of the blood-pressure cuff when it is wrapped about the appendage. The sheet is two-ply, having an exterior layer (18) of soft absorbent material and an interior layer (20) of more liquid impervious material. The bottom band is wrapped about the appendage, the blood-pressure cuff is wrapped about the bottom portion, and the top band is pivoted relative to the bottom band at the intermediate portion over the blood-pressure cuff and wrapped thereabout.
Abstract: The stem of the femoral prosthesis is provided with a slot in the medial narrow side which communicates with a through-bore within the stem adjacent to the collar. In addition, an elastomeric filling is disposed within the through-bore and cooperates with an arch which connects the proximal end of the stem to the collar or neck in order to adapt the resilience of the stem in the proximal zone to the resilience of the cortical bone. The filling may be made of polyurethane or silicone material.
Abstract: A prosthesis holding system is provided for holding and positioning a prosthetic cup during surgery. The rim of the cup includes opposed inwardly and outwardly facing recesses. A holder includes an elongated rod having a shoe at one end. The shoe includes a tab for engaging the inwardly facing recess in the rim of the cup. The shoe further includes a threaded aperture alignable with the outwardly facing recess in the rim of the cup. A clamping screw is engageable with the threaded aperture and is further engageable with the outwardly facing recess in the rim of the cup. Tightening of the clamping screw securely holds the cup without interfering with either the interior concave surface of the cup or the exterior convex surface of the cup, to enable efficient implantation of the cup in a patient during surgery.

Abstract: An improved artificial leg comprising a socket fitted to mate comfortably to an amputee's stump and having a vise-like attaching member mounted thereon, a stem portion having an attaching portion adapted for releasable mating with the attaching member of the socket and having a foot member comprising a semi-spherical ring secured to the lower end of the stem, a generally semi-spherical base member rotatably secured to the ring, a resilient sole covering the bottom of the base member and a boot formed of resilient material secured to the stem and serving to mormally urge the base member to a predetermined position with respect to the stem.
Abstract: A miniaturized forge consisting of a metal body with slots and openings to admit the metal to be heated, along with a bracket for holding a separate fuel tank containing a torch which extends vertically downward through a hole in the metal body. The torch within the forge is able to selectively heat areas of metal objects to a temperature high enough to allow them to be bent into a desired shape.
