Patent number: 8939916Abstract: Medical devices for navigation through anatomy, including guidewires, which may have a core wire, a slotted tubular member, or both. Embodiments may have coils, including non-circular cross-section edge-wound marker coils, extended coil tips, and soldered or glued mesial joint coils. Core wires may have a step, ridge, or taper at the joints to the tubular member, and may be flattened at the distal tip. Radiopaque material may be located inside the tubular member, and the distal tip may be heat treated to make it shapeable. Additional tubular members or coils may be used concentrically or in line and may enhance flexibility, provide radiopacity, reduce friction, or reduce material or manufacturing cost. Tubular members may be chamfered or tapered continuously or incrementally. Slots may be arranged in groups, such as groups of three, and may be equal in depth or unequal in depth to provide a steerable or compressible tip.Type: GrantFiled: July 31, 2007Date of Patent: January 27, 2015Assignee: Precision Vascular Systems, Inc.Inventors: Stephen C. Jacobsen, Clark C. Davis, Clay W. Northrop, Ted W. Layman, Kevin T. Olson, Edward J. Snyder, D. Kent Backman, Todd H. Turnlund

Patent number: 7540857Abstract: A catheter securement device which automatically deploys one or more sutures to secure a catheter without requiring the practitioner to manually suture the catheter to the self-suturing anchor device. A ratchet mechanism having one or more rotatable ratchet members which pivot and a ratchet member engagement spring which maintains contact between the teeth of the rotatable ratchet member and the teeth of the ratchet ring. An O-ring is provided to maintain the position of the sutures to minimize disruption of the sutures before deployment of the sutures. In one embodiment, a stationary base of the anchor device comprises a single molded member. In another embodiment a method of manufacturing the catheter anchor device comprising welding a rotatable ring and one or more bearing members of the catheter anchor device through access bores in the stationary base.Type: GrantFiled: August 11, 2005Date of Patent: June 2, 2009Assignee: Merit Medical Systems, Inc.Inventors: D. Kent Backman, Brian Stevens, Greg McArthur, William Padilla, Fred P. Lampropoulos

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
