Patent number: 9913635Abstract: Various embodiments of a device are shown and disclosed for closing a vascular access puncture site following percutaneous diagnostic or therapeutic interventional procedures. The vascular closure device is configured to safely and accurately deploy a sealing material that undergoes a phase change when deployed inside the tissue tract. The sealing material may be a solid at room temperature and a liquid or gel at body temperature. Also, the sealing material may change from a liquid or gel to a cubic phase when it comes into contact with bodily fluids.Type: GrantFiled: December 22, 2015Date of Patent: March 13, 2018Assignee: ST.

Patent number: 9750489Abstract: An internal tissue puncture closure method and apparatus. The method and apparatus provide a folded sealing plug that provides more surface area than conventional plugs to more fully cover and seal an external situs of an internal tissue puncture. The folded sealing plug may have a weave pattern that tends to cause the sealing plug to corkscrew into the internal tissue puncture as it is compressed toward an anchor placed inside of the tissue puncture.Type: GrantFiled: May 21, 2015Date of Patent: September 5, 2017Assignee: TERUMO PUERTO RICO, L.L.C.Inventors: Catherine A.

Patent number: 9655603Abstract: A vessel puncture closure device includes a balloon catheter and a sealant delivery device. The balloon catheter has an inflatable balloon positioned at a distal end thereof. The sealant delivery catheter has a sealant lumen configured to delivery a volume of sealant to a vessel puncture. The sealant delivery catheter is configured to move axially relative to the balloon between a first position in which the sealant delivery catheter delivers a first volume of sealant to the vessel puncture, and a second position spaced proximal of the first position to deliver a second volume of sealant to the vessel puncture.Type: GrantFiled: February 27, 2013Date of Patent: May 23, 2017Assignee: ST.

Publication number: 20170135682Abstract: A tissue puncture locator device includes an anchor assembly and a sealing member. The anchor assembly includes an anchor portion, a tube portion, and a filling member. The anchor portion is positioned at a distal end of the tube portion and configured for placement through a vascular incision into a vessel. The anchor member has an unexpanded configuration that permits passage through the vascular incision and an expanded configuration that limits passage through the vascular incision. The filling member is retained in the tube portion and adapted for insertion from the tube portion into the anchor member to provide the expanded configuration, and adapted for retraction from the anchor member into the tube portion to provide the unexpanded configuration. The sealing member is configured for placement adjacent the vascular incision outside the vessel.Type: ApplicationFiled: January 27, 2017Publication date: May 18, 2017Applicant: St. Jude Medical Puerto Rico LLCInventors: Valerie J.

Patent number: 9603588Abstract: A tissue puncture locator device includes a temporary anchor configured for placement through a vascular puncture into a vessel. The temporary anchor includes a column member that defines a lumen. The temporary anchor is movable between an uncompressed position and a compressed position, wherein in the compressed poition a portion of the column member protrudes radially outward. The column member may include a reduced thickness portion, wherein the column member protrudes radially outward at the reduced thickness portion. The column member, when expanded radially outward within the vessel, is sized to limit retraction of the temporary anchor through the vascular puncture.Type: GrantFiled: August 20, 2010Date of Patent: March 28, 2017Assignee: ST.
