Patent number: 7520869Abstract: 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.Type: GrantFiled: March 16, 2005Date of Patent: April 21, 2009Assignee: Merit Medical Systems, Inc.Inventors: Fred P.

Patent number: 7470256Abstract: 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.Type: GrantFiled: August 5, 2005Date of Patent: December 30, 2008Assignee: Merit Medical Systems, Inc.,Inventors: Fred P. Lampropoulos, Arlin Dale Nelson, D. Kent Backman, Gregory R. McArthur, Thomas D. Stout, Brian Stevens

Patent number: 7458463Abstract: A bio-waste container with integrated needle stop is disclosed. The apparatus includes a catch basin and a waste opening. The catch basin is configured to hold biological and other material, and the waste opening provides an aperture through which such biological and other materials can be deposited in the catch basin during the course of the procedure. The bio-waste container also includes an integrated needle stop apparatus having a cushion layer providing a depository for needles and other sharp tipped objects. The needle stop apparatus further includes a puncture resistant layer which prevents the needles or other sharp tipped objects from penetrating beyond the cushion layer. The needle stop apparatus is secured to the bio-waste container in such a way that it is securely coupled to the bio-waste container during shipping and use, but is selectively removeable from the bio-waste container for separate disposal.Type: GrantFiled: October 13, 2004Date of Patent: December 2, 2008Assignee: Merit Medical Systems, Inc.Inventor: Fred P. Lampropoulos

Publication number: 20080269785Abstract: 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 puncture site without causing puckering or distortion of the skin at the purse string suture site. The suture securement apparatus permits a practitioner to subsequently modify 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.Type: ApplicationFiled: April 18, 2008Publication date: October 30, 2008Applicant: MERIT MEDICAL SYSTEMS, INC.Inventors: Fred P.
