  • Patent number: 6171324
    Abstract: A corneal marker and a method of using a corneal marker are disclosed. The corneal marker includes a handle having a head coupled thereto. The inferior surface of the head includes a set of protuberances which form marking surfaces adapted to simultaneously engage corneal tissue. The marking surfaces form opposing sets of marks which allow a surgeon to form an incision of precise length and width. An alignment line on the superior and/or front surface of the marker facilitates the positioning thereof. A method of performing clear corneal surgery following the application of markings to the cornea is also provided.

  • Patent number: 6120482
    Abstract: A needle guard assembly is provided for mounting to the hub of a needle assembly. The needle guard assembly includes a guide that is engageable on the hub. An elongate U-shaped cover is hingedly mounted to the guide and can be rotated from a first position where the needle cannula is substantially surrounded by the U-shaped walls of the cover into a second position where the needle cannula is exposed for use. The needle guard assembly further includes a slide that is slidably engaged in the guide and movable from a first position where the slide cooperatively engages the cover for completely surrounding the needle cannula to a second position where the slide is spaced proximally from the cover, thereby permitting the cover to rotate into its second position.

  • Patent number: 5989219
    Abstract: A syringe assembly comprises a barrel having an inside surface describing a chamber for retaining fluid. The barrel includes an open proximal end and a distal end with an elongated tip extending therefrom having a passageway therethrough in fluid communication with the chamber. A plunger rod includes an elongated body portion having a proximal end, a distal end and a stopper at the distal end. The stopper is slidably positioned in fluid-tight engagement within the barrel. An elongated projection extends distally outwardly from the distal end of the plunger rod. The elongated projection is shaped to fit within the passageway of elongated tip. Structure is provided to prevent the removal of a needle assembly from the elongated tip of the syringe barrel. A locking element is provided to prevent the proximal motion of the plunger rod with respect to the barrel after initial distal motion of the stopper to expel fluid from the syringe barrel.

  • Patent number: 5947933
    Abstract: A hypodermic syringe assembly is provided with a syringe barrel and a safety shield telescoped over the syringe barrel and movable from a proximal position to a distal position. The safety shield is irreversibly lockable in the distal position on the syringe barrel to protectively shield a used needle cannula. The safety shield is releasably retained in a proximal position by engagement of a protrusion on the barrel and a groove on the shield. Engagement between the protrusion and the stop block can be overcome by rotating the safety shield. The safety shield may then be moved into an irreversible shielding position surrounding the needle cannula. The releasable retention of the safety shield in its proximal position prevents inadvertent distal movement of the safety shield.

  • Patent number: 5925020
    Abstract: A needle point barrier includes a resiliently deflectable spring arm, a link arm and a barrier arm. The proximal end of the spring arm is secured near the proximal end of the needle. The link arm has one end hingedly connected to the spring arm and an opposed end hingedly connected to a proximal position on the barrier arm. Distal portions of the barrier arm slidably engage the needle. The needle point barrier can be collapsed into a Z-shaped configuration near the proximal end of the needle. The barrier arm can be urged distally by force applied to the proximal end of the barrier arm. Initial movement of the barrier arm will deflect the spring arm away from the needle. After sufficient manual movement of the barrier arm, the resiliency of the spring arm will urge the barrier arm distally into shielding relationship with the distal end of the needle.

  • Patent number: 5919165
    Abstract: A needle shield assembly is provided for a needle cannula. The assembly includes a support sleeve, a stop collar and a needle shield. The support sleeve is rotatably mounted in a proximal position about the needle cannula. The stop collar is secured on the needle cannula distally from the support sleeve so that the stop collar traps the support sleeve in a proximal position on the needle cannula. The needle shield is hingedly mounted to the support sleeve for rotation between a first position where the needle shield protectively encloses the needle cannula and a second position where the support sleeve is angularly aligned to and spaced from the needle cannula. The hingedly connected needle shield and support sleeve can be rotated around the needle cannula.

  • Patent number: 5910130
    Abstract: A shieldable needle assembly includes a needle guard slidably movable along a needle cannula from a proximal position where the distal end of the needle cannula is exposed to a distal position where the distal end of the needle cannula is safely shielded within the needle guard. A hinged arm assembly connects the needle guard assembly to needle hub. A trigger is articulated to the needle hub at a location proximally of the hinged arm. Distally directed digital forces cause the trigger to rotate such that the trigger urges the hinged arm from a collapsed condition to an extended condition.

  • Patent number: 5893842
    Abstract: A syringe assembly having needle isolation features includes an elongate barrel having an open proximal end, a chamber for retaining fluid and a tip portion extending from a distal end of the barrel having a passageway therethrough include communication with the chamber. A valve housing extends outwardly from the tip portion of the barrel having a conduit therethrough in communication with the passageway. A needle cannula having a proximal end, a distal end and a lumen therethrough is provided. The proximal end of the needle is connected to the housing so that the lumen is in fluid communication with the conduit. The housing includes internal valve for allowing liquid under pressure in the chamber to flow distally through the conduit and the lumen while preventing unpressurized liquid in the chamber from flowing through the aperture. The internal valve includes a one-way valve structure for preventing liquid flow through the conduit in a proximal direction toward the chamber.
