Publication number: 20230001161Abstract: An interventional catheter is adapted for treating a blood vessel. In an embodiment, the catheter includes an elongate shaft sized for insertion in a blood vessel and a stent positioned on a distal region of the elongate shaft. An expandable dilation member is coupled to a distal region of the elongate shaft. The expandable dilation member is adapted to expand outward. A stent containment member is positioned over the elongate shaft and the stent to contain the stent in a collapsed state.Type: ApplicationFiled: May 20, 2022Publication date: January 5, 2023Inventors: Tony M.

Patent number: 11389155Abstract: A suture-based vessel closure device can perform the dilation of an arteriotomy puncture and does not require previous dilation of the arteriotomy puncture by a separate device or by a procedural sheath dilator. The suture-based vessel closure device can place one or more sutures across the vessel access site such that, when the suture ends are tied off after sheath removal, the stitch or stitches provide hemostasis to the access site.Type: GrantFiled: July 16, 2019Date of Patent: July 19, 2022Assignee: Silk Road Medical, Inc.Inventors: Michi E. Garrison, Gregory M. Hyde, Richard J. Renati, Alan K. Schaer, Tony M. Chou

Patent number: 9138527Abstract: A retrograde flow system is configured for treating an artery. The system includes an arterial access device adapted to be introduced into an artery and receive blood flow from the artery. A shunt fluidly is connected to the arterial access device, wherein the shunt provides a pathway for blood to flow from the arterial access device to a return site. A flow control assembly is coupled to the shunt and is adapted to regulate blood flow through the shunt between at least a first blood flow state and at least a second blood flow state. A shut-off valve assembly automatically blocks fluid flow through the shunt in response to injection of the fluid into the arterial access device.Type: GrantFiled: September 30, 2013Date of Patent: September 22, 2015Assignee: Silk Road Medical, Inc.Inventors: Richard J. Renati, Michi E. Garrison, Alan K. Schaer, Gregory M. Hyde
