  • Patent number: 9039682
    Abstract: A suture securement apparatus for selectively securing one or more ends of a suture while allowing adjustments in the tension or a full release of the sutures intermittently after a prolonged period of time. The suture securement apparatus can be particularly adapted for use with a purse-string suture to close a percutaneous catheter insertion site without causing puckering or distortion of the skin at the purse string suture site. The suture securement apparatus allows for subsequent modification of the amount of tensioning or full release of the sutures at the catheter insertion site. A threading assembly for use with the suture securement apparatus and being adapted to facilitate threading of sutures along the length of the suture securement apparatus. An adhesive suture securement device to provide securing sutures to be utilized with a suture securement apparatus. An adhesive securement device to provide a cradle configured to secure a hub of a catheter or other medical instrument or device.

  • Publication number: 20150045828
    Abstract: A filter configured to be disposed within the vasculature to capture or trap material within a body lumen is disclosed. The filter may be configured to be removable and may be configured to slice through ingrown or encapsulated tissue during removal. A filter deployment device or system which may be configured to deliver a filter or filters to a position within a body lumen, such as within the vasculature, is also disclosed. The filter deployment device may be configured to limit inadvertent decoupling of a filter. Also, the filter deployment device may be configured to retrieve a deployed filter.

  • Patent number: 8951270
    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. A threading assembly for use with the surgical securement apparatus that is adapted to facilitate threading of a cord along the length of the surgical securement apparatus.

  • Patent number: 8845680
    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: 20140276592
    Abstract: The embodiments disclosed herein relate to lockable syringe assemblies and related devices and methods. The syringe assembly may include a barrel, a plunger, and a locking mechanism. In some arrangements, the locking mechanism is an elastomeric locking ring or a rigid partial ring. The plunger may include a plurality of ribs and is longitudinally moveable within the barrel. Once the plunger is disposed at a desired longitudinal location, the plunger can be axially rotated and locked in such a way that further longitudinal movement is restricted.

  • Publication number: 20140254303
    Abstract: A movable mixing disc may be utilized in connection with a syringe. The mixing disc may comprise a hole which may be covered by a fine screen or coupled to a porous member, allowing only certain elements of a solution to pass through the mixing disc. Actuation of a plunger of the syringe may cause liquid to emerge from the mixing disc hole as a high velocity jet or other turbulent flow, stirring up any settled particles on a distal side of the mixing disc. As the ejection continues, the mixing disc may be pushed forward by the plunger in order to eliminate any unused volume. Also, the mixing disc may be moved forward by virtue of a pressure difference created by a pressure drop across the mixing disc, such as a pressure drop created as the plunger is displaced to induce fluid flow across the mixing disc.
