Abstract: A vascular closure device comprised of a sheath-delivered cincture or noose-like device or knot comprised of suture, wire, or other suitable materials, that is placed on the external surface of a puncture wound, and closed. The vascular closure cincture is delivered by a sheath, and after closing is left resident on the external surface of a tissue puncture wound.

Abstract: A vascular closure device comprised of a sheath-delivered expandable, umbrella-like device with structural radial members with terminal and non-terminal hooks that engage the vessel wall. Unlike other vascular closure umbrella-type devices that effect closure by opening of the umbrella to cover an opening, the present invention effects closure of the aperture with closure of the umbrella. The closure can be maintained by a retainer lock that slides down the members, causing contraction, bringing the members into a compressed configuration (e.g., a parallel orientation of linear members) and the wound edges together, permitting immediate vascular closure and healing of the blood vessel. The device can be delivered and recovered by an intravascular sheath.

Abstract: A vascular closure device comprising a retrievable sheath-delivered contractible, clip device with structural radial or terminal members with terminal and non-terminal hooks that engage the vessel wall. Unlike other vascular closure clips, this device is delivered on the outside rather than the inside of sheath. Closure of the tissue opening can be effected by the feet of the clip engaging the puncture, aperture, or wound edges and memory characteristics of the device cause a contraction of the members, bringing the members into apposition and the wound edges together, permitting immediate vascular closure and healing of the blood vessel. The device can be delivered and recovered by an intravascular sheath.

Abstract: Tissue eversion apparatuses and methods suitable for use, as examples, with vascular closure devices. The tissue eversion apparatuses comprise a tissue engaging element, disposed within a delivery sheath. The delivery sheath protects the tissue engaging element and the surrounding tissue during use. The tissue engaging element can extend from the sheath and engage the tissue near an aperture in a tissue wall. Motion of the tissue engaging element away from the tissue can urge the tissue wall near the aperture to evert from the tissue wall, allowing, as examples, aperture closure apparatuses and methods to be conveniently employed.

Abstract: A reciprocating syringe assembly may include a housing having a receptacle structured and arranged to removably receive a syringe and a syringe removably disposed in the receptacle. The syringe comprising a syringe plunger, and the housing may include at least one track. The assembly may include a plunger slidable in the track. The plunger may be mechanically coupled to the syringe plunger such that movement of the plunger in a first direction causes movement of the syringe plunger in a second direction opposite to the first direction and movement of the syringe plunger in the first direction causes movement of the plunger in the second direction.

Abstract: A reciprocating syringe that can be used in connection with existing syringe barrels and fittings. Some embodiments comprise a frame, adapted to retain two existing syringe barrels. The frame can accommodate fittings on one or both barrels. The invention also provides a plunger complex, comprising two plungers, each adapted for use with one of the syringe barrels. The two plungers are coupled such that pushing of each plunger into its barrel causes the other plunger to pull outwards relative to its barrel. The two plungers can be coupled by a flexible line attached to one plunger, routed from the plunger out of the corresponding barrel into the other barrel, and attached to the other plunger. The invention contemplates various frame configurations to accommodate desired line and pulley performance characteristics. Other embodiments comprise a frame adapted to retain an existing syringe barrel, and an auxiliary actuator mounted with the frame.

Abstract: The present invention provides a syringe device comprising: a first syringe comprising: a first syringe barrel including a first opening at a distal end thereof through which fluid may be forced or aspirated; and a first syringe plunger sliding within the first syringe barrel for forcing fluid through the first syringe barrel opening, the first syringe plunger including a stopper at a distal end thereof which sealingly and slidably engages the first syringe barrel; a reciprocating member which moves along a track parallel to the axial direction of the first syringe; and a reciprocating device connecting the first syringe plunger to the reciprocating member so that when one member of the group consisting of the first syringe plunger and the reciprocating member moves distally, the other member of the group is forced to move proximally.

Abstract: A cap or sheath locks onto the needle or other sharp, thus permanently inactivating the needle or other sharp, preventing any further use of the device, and permanently isolating the contaminated sharp. Four components are a needle or sharp to accommodate a locking collar, a sheath with a external, internal, or horizontal track to accommodate a locking collar, a locking collar that moves inferiorly within or outside the sheath, or horizontally that binds to the sheath or needle, permanently locking the needle in the sheath and mechanically preventing the needle from moving from the sheath, and a locking mechanisms for these devices. Handles are advantageously provided for the sheath to permit safe recapping or resheathing so that the needle can be bound in the sheath and inactivated.

Abstract: Medical devices and consumables have been altered by changes on their surfaces or components consisting of simple or complex color patterns, visual designs, drawings, art work, embedded designs, copyrighted images or figures, changes in the shape of the medical device in an artistic, abstract, or visual manner, and other visual and physical modifications intended to improve the physical and psychological environment of the patient and the health care worker, and to be used as well to visually identify a particular medical device, component, solution, or medication.

Abstract: A reciprocating syringe is described. The syringe includes a syringe barrel with a syringe plunger with a thumb rest for injecting or aspirating fluid and reciprocating member with thumb a rest which move in a guide track and a reciprocating device connecting the syringe plunger to the reciprocating member so that when the syringe plunger moves in one direction the reciprocating member moves in the opposite direction.

Abstract: A butterfly needle assembly has a needle and a shield with wings integral to either the needle or the shield. The wings have aesthetically pleasing patterns to distract the patient during treatment. The mechanical design of the needle and shield juncture improves the stability of the assembly when inserted into a patient, as well as allowing the assembly to be disengaged with a single hand to help the caregiver avoid a needle “stick” and prevent the spread of diseases.
