Patent number: 11648002Abstract: Anchor delivery systems include markings on the surfaces of the delivery device which are visually exposed to the user through openings or fenestrations in the anchor, providing visual feedback to the user on the progress of the anchor's insertion. A suture-locking plug is deformable within the anchor tip, thereby enhancing suture entrapment within the tip of the anchor. A compliant component of the handle places the handle components in tension, thereby absorbing built-in axial looseness in the handle. The handle further includes a spin cavity which allows for free spin of the inserter shaft to finalize insertion of the anchor into bone when the anchor has not been fully seated flush with or below the cortical bone surface.Type: GrantFiled: March 17, 2021Date of Patent: May 16, 2023Assignees: Smith & Nephew, Inc., Smith & Nephew Orthopaedics AG, Smith Nephew Asia Pacific Pte.

Patent number: 11633198Abstract: An aspiration clot retrieval catheter to have profiled guidewire for deliverability that transitions at a proximal joint to a distal tubular section with a lumen for directing aspiration and facilitating the smooth passage of other products in performing mechanical thrombectomy procedures. The joint can have a low-profile proximal strut formed integrally with the distal tubular section and configured to interlock with a distal portion of the guidewire so that there is a smooth transition of stiffness between the guidewire and the tubular portion of the catheter to improve trackability and decrease the likelihood of kinking. The distal tubular section of the proximal joint can also have features to tailor flexibility. The tubular section can be configured to push radially outward to form a seal with an outer catheter to optimize aspiration transmission to the distal mouth of the aspiration clot retrieval catheter.Type: GrantFiled: March 5, 2020Date of Patent: April 25, 2023Assignee: Neuravi LimitedInventors: Karl Keating, Ronald Kelly, David Vale

Patent number: 11622874Abstract: A guide cap and a loading system for loading an implant into a delivery system are disclosed which are capable of simplifying operations required in interventional surgery using the implant. The guide cap has a lumen passing therethrough and includes: a conical section; a straight or conical tube in communication with a small open end of the conical section; and a flange, wherein a large open end of the conical section flares outward and thereby forms the flange. The loading system includes a guider and the guide cap. During the process of loading the implant into the delivery system, the guide cap enables the valve prosthesis to be coupled to the connector of the delivery system and allows the valve prosthesis to be compressed so as to be entirely capsuled in the delivery system with relatively easy and quick operations, thereby reducing surgery time during its clinical use.Type: GrantFiled: September 11, 2018Date of Patent: April 11, 2023Assignee: SHANGHAI MICROPORT CARDIOFLOW MEDTECH CO., LTD.Inventors: Xiang Liu, Mingming Wu, Baozhu Gui, Guoming Chen

Patent number: 11583398Abstract: A modular prosthetic valve device for implantation in a patient and a system for and method of delivering such a modular valve device and assembling it in vivo are disclosed. The valve device is designed as two or more modules to be delivered unassembled, spatially separate, and combined into an assembled valve device in the body at or near the site of implantation. The valve device of the invention is deliverable as modules, providing a smaller delivery diameter than pre-assembled percutaneous valves, permitting use of a delivery device of reduced diameter, and increasing the flexibility of the valve device during delivery, compared to percutaneous valve devices in the art. The modules of the valve device may be connected by pull wires for delivery sequentially, and then assembled by remote manipulation using the pull wires. Various locking mechanisms are provided for attaching the device modules together.Type: GrantFiled: November 22, 2019Date of Patent: February 21, 2023Assignee: Valve Medical Ltd.Inventors: Yoram Richter, Jacob Richter
