A body-implantable lead includes an electrical conductor encased in inert, insulating material. The lead terminates at one end with an exposed electrode tip. A first set of tines is positioned about the lead nearest the electrode tip, the tines having a length less than the tines of a second set positioned about the lead and more remote from the electrode tip than the first set. The tines of the first set may also carry fins which extend toward the electrode tip to facilitate lead insertion. The tines may also be disposed in longitudinal or spiral rows along the lead.

Tined leads

A suture sleeve and associated gripping enhancing structure which extend longitudinally of an elongate axis of the suture sleeve which has a lumen therein and received over a lead body of a pacing lead. The gripping enhancing structure is radially compressible with the suture sleeve upon the tying of sutures around the suture sleeve to facilitate gripping of the lead body by the suture sleeve and/or gripping enhancing means. The gripping enhancing structure can be formed within and integral with the suture sleeve, or can be a separate thermoplastic part which is insert molded into the suture or which is received on and around the suture sleeve.

Suture sleeve with structure for enhancing pacing lead gripping

The bipolar temporary pacing lead comprises a lead body having a proximal end portion and a distal end portion and including first and second spaced apart wire conductors each encased in an insulating material to form insulated wire conductors. A curved needle is connected to at least one of the first and second wire conductors in the lead body distal end portion. A straight needle is connected to a first elongate non-conductive member and a second elongate non-conductive member which are connected by means of first and second terminal sleeves to proximal ends of the first and second wire conductors. The distal end portion of the lead body has insulation removed from portions of the respective first and second insulated conductors thereby to form in the lead body distal end portion a first electrode-forming, bare wire conductor portion and a second electrode-forming, bare wire conductor portion.

A child-resistant safety closure is provided for closing the outlet of a hand-operated fluid product sprayer dispenser used on a container to prevent leaks from the container during periods of non-use and to resist accidental use by children or unwary adults. The closure cannot be moved from an 'outlet closed' position to an 'outlet open' position without the performance of at least two discrete, predetermined definite actions by the user to first disable a lock and then to linearly or rotatably move the cap into the 'outlet open' position to permit spraying or dispensing. A closing member is connected to the bottom portion of the sprayer for removably mounting the sprayer to the container and closing the same. The member and the sprayer to which it is connected cannot be removed without the performance of at least two discrete, predetermined definite actions, which actions are difficult if not impossible for young children to perform.

Child-resistant closures for container mounted spray dispensers

A manually operated dispensing device for a container holding a quantity of liquid is disclosed. The device has an internal chamber and a flexible, elastomeric diaphragm-like cover on at least one side of the chamber in a component retaining body. Associated inlet and outlet valves, which valves may be discrete or integral with the diaphragm and body, and conduits are included whereby liquid from a supply thereof in the container is drawn up into the chamber when the diaphragm is flexed under stress. The diaphragm is operatively associated with a trigger device, the actuation of which flexes and stresses the diaphragm in a direction to decrease the chamber volume. Liquid which is present in the chamber is displaced and pressurized in a pumping action, forcing the outlet or discharge valve to open and the inlet valve to close allowing the liquid to flow into the outlet or discharge conduit and be dispensed from the device. Alternate application and relief of the above described flexing or stressing action of the diaphragm by alternate actuation and release of the trigger causes the inlet and outlet valves to alternately open and close, and liquid to be drawn into the chamber and be dispensed therefrom.

Manually operated, trigger actuated diaphragm pump dispenser

A manually operated dispensing device for a container holding a quantity of liquid is disclosed. The device has a variable volume pump chamber within a component retaining body. The chamber is defined by a bellows having a closed end or bottom, an open end or top, and corrugated sidewalls characterized by their resilience or elastic memory, and fabricated of any of the various thermoplastics. The bellows is associated with a movable member in the form of a trigger which when actuated compressively stresses the bellows in a direction significantly to reduce its length and the volume of the chamber therewithin. When the compression stress applied by the actuating member or trigger is relieved or removed, the bellows regains its original size and shape and returns the actuating member to its initial position. Associated inlet and outlet valves and respective conduits are also incorporated in the device whereby liquid in the liquid container is drawn into the chamber and pumped through a discharge nozzle in the form of a spray, as desired. The alternate application and relief of compressive stress by the trigger or operating member also opens and closes the valves so that liquid can be drawn into the chamber and dispensed therefrom.

Manually operated liquid dispensers

A manufacture of fluid handling devices having a variety of different surface contours or appearances features a universal fluid handling component retaining body and a shroud for enclosing the universal body, the shroud being a selected one of a variety of shrouds that are fabricated separately from the body and that are characterized by having a common internal surface configuration for engaging in permanently affixed, or removable relation, predetermined, selected exterior portions of the universal body, and further, that are characterized by having different external or surface contours or appearances, the latter being determined by merchandising or consumer preference.

Sprayer nozzle

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).

Nozzle assembly

A manually operated fluid dispensing device includes a first body component formed with a pump chamber and an upwardly opening cavity providing a valve housing that is closed by a second mating body component or cover having a projection that extends into the valve housing. A flat pliable valve element is clamped between said body components, said element being imperforate except for an opening through which said projection extends. A compressible bellows is associated with the pump chamber to form a variable volume pump chamber. The parts are all fabricated of thermoplastic materials and molding resins, the mating body components each being molded as a simple member of rigid plastic and including all passageways, grooves and ring seals required in the device.

Fluid dispensing device

A very compact foam-generating element for use in conjunction with a trigger-actuated dispenser is characterized by its insensitivity to its manner of attachment to and adjustment on the dispenser and features a combination of foam forming means located upstream of an expansion chamber having a nozzle at its inlet and terminated downstream by screening means, the screening means, expansion chamber and nozzle cooperating to produce a tightly packed, fine textured foam of even consistency by extending the time of treatment of the semi prepared foam received from the foam forming means, the screening means meanwhile adding air and further breaking up the liquid. The foam forming means provides non-contact jetting of the liquid through an aspirating chamber into a foam forming chamber having a diameter or cross section that is substantially the same as that of the aspirating chamber. The diameter or cross section of the expansion chamber preferably is substantially larger than that of the foam forming chamber. In one embodiment the foam-generating element is adapted to fit over the nozzle of a trigger-type dispenser; in another embodiment the element replaces the nozzle altogether; and in further embodiments the element is incorporated within the molded structure of trigger-actuated piston type and bellows type dispensers to form integral foam dispensers.
