  • Publication number: 20100280541
    Abstract: A radial artery compression device configured to be secured to a wrist or other portion of a patient to provide adjustable and consistent compression pressure in the area of a radial artery access site or other physiological portion of a patient to achieve hemostasis either during or after a medical procedure such as a percutaneous coronary procedure. The radial artery compression device includes a rotatable member and a compression pad adapted such that rotation of the rotatable member does not affect the rotational orientation of the compression pad. According to one embodiment of the present invention, a single rotation of the rotatable member results in complete extension or retraction of the radial artery compression device. According to another embodiment of the present invention, the rotation of the rotatable member results in a compounding of the extension or retraction of the compression pad relative to the body of the radial artery compression device.

  • Publication number: 20100057110
    Abstract: A surgical securement apparatus for selectively securing one or more ends of a cord while allowing adjustments in the tension or a full release of the cord intermittently after a prolonged period of time. A surgical securement and marking system utilizing one or more surgical securement apparatus that are color-coded to convey information about the associated intercorporeal structures. The surgical securement apparatus can be particularly adapted for use in securing intracorporeal structures such as nerves, blood vessels, and tendons during a surgical procedure. An extender tube connected to the surgical securement apparatus enables securement of intracorporeal structures within the surgical site from outside the surgical site. The surgical securement apparatus permits a practitioner to subsequently modify the amount of tensioning or to fully release the cord.

  • Patent number: 7520869
    Abstract: A self-suturing anchor device includes a base having a securement mechanism. The securement mechanism includes one or more resilient pockets in which are placed a plurality of looped sutures. The securement mechanism and looped sutures facilitate automatic securement of a catheter relative to the self-suturing anchor device. In at least one embodiment, the looped sutures are also threaded through loops in another corresponding looped suture, such that each looped sutures slidably tighten in concert with one another. When at least a portion of the securement mechanism is moved, at least one of the plurality of looped sutures is tensioned and closes against a securement point on the catheter. A catheter can be secured in a self-suturing anchor device in a quick and efficient manner with minimal effort.

  • Patent number: 7470256
    Abstract: A self-suturing anchor device includes rotatable ring adapted to automatically deploy sutures to secure a catheter. The rotatable ring is utilized in connection with a ratchet mechanism which allows movement of the rotatable ring in a first direction while preventing movement of the rotatable ring in the opposite direction. The rotatable ring is also utilized in connection with a bearing member to facilitate smooth and efficient rotation of the rotatable ring. An extension saddle is utilized to provide a desired amount of displacement between suture securement points to minimize pivotal movement of the catheter. The rotatable ring is wider than its height to minimize kinking of the catheter tube and to relieve pressure when pressed between the patient and a support surface. In another embodiment, a plurality of scallops or other gripping members are utilized to facilitate easy gripping and rotation of the rotatable ring.

    Abstract: This invention relates to a measuring device, which includes a body. A digital display is located in the body, the digital display being configured to show at least a linear measurement. The measuring device also includes a holding portion coupled to the body and configured to slidably engage an elongate member, such as a catheter or introducer sheath, in a space provided between the holding portion and the body. The measuring device also includes a sensor or transducer located in the body and configured to measure at least a linear distance traveled by the elongate member, such that the linear measurement is associated with the linear distance.

  • Patent number: 6050981
    Abstract: The present invention relates to a system for irrigating a wound with wound irrigation fluid and for preventing substantial splashback of the wound irrigation fluid. The system comprises: (i) fluid delivery device for delivering wound irrigation fluid; and (ii) a flexible wound irrigation shield configured such that the shield prevents substantial splashback of the irrigation fluid upon irrigation of a wound. The shield is configured to be disposed, preferably removably, on the fluid delivery device. The flexible shield is substantially conformable to a desired wound area, enabling the practitioner to irrigate awkward, uneven, and hard to reach areas. The shield can be folded into a compact position, then opened into a larger shield. The fluid delivery device comprises (i) a fluid source for providing wound irrigation fluid; and (ii) an adaptor for transmitting fluid from the fluid source to the wound.

  • Patent number: 5823967
    Abstract: A flush valve having a fluid receiving housing having a first passageway, a fluid discharge housing having a second passageway, and a flow restricting device having a capillary tube defining a primary fluid flow path extending between the first passageway and the second passageway. An elastomeric sealing tube encircles and is biased against the exterior surface of the flow restricting device. A secondary fluid flow path extends from the first passageway to the second passageway between the interior surface of the sealing tube and the exterior surface of the flow restricting means so as to bypass the capillary tube. A connecting plate connects the fluid receiving housing to the fluid discharge housing. Projecting from the connecting plate, receiving housing, and discharge housing are individual pairs of clamping fingers that are longitudinally aligned to form a single U-shaped channel.

  • Patent number: 5807321
    Abstract: A system and method for electronically monitoring and displaying digital flow data relevant to the administration of a parenteral fluid, such as a contrast medium, to a patient is disclosed. The system includes a disposable fluid flow indicator, adapted to be detachably connected in fluid communication with a contrast media source. The fluid flow indicator measures the amount of contrast media dispensed from the source and administered to a patient, and provides an indication of the amount dispensed based on the movement of a displacement indicator.Also disclosed is an electronic controller, which is adapted to be detachably connected to the fluid flow indicator. The controller includes a sensor interface circuit, which operably interfaces the electronic controller circuitry with the fluid flow indicator so that the fluid flow measurement indicator is optically detected by the sensor circuit, which in turn generates a representative electrical flow signal.
