Publication number: 20220225975Abstract: A sealant is provided for sealing a puncture through tissue that includes an elongate first section including a proximal end, a distal end, and a cross-section sized for delivery into a puncture through tissue, and a second section fused to and extending from the distal end of the first section. The first section may be formed from a freeze-dried hydrogel that expands when exposed to physiological fluid within a puncture. The second section may be formed from a solid mass of non-freeze-dried, non-crosslinked hydrogel precursors, the precursors remaining in an unreactive state until exposed to an aqueous physiological, whereupon the precursors undergo in-situ crosslinking with one another to provide an adhesive layer bonded to the first section. Apparatus and methods for delivering the sealant into a puncture through tissue are also provided.Type: ApplicationFiled: August 30, 2021Publication date: July 21, 2022Inventors: Andy H. UCHIDA, Anthony P. SPIZUOCO, Kevin TO, Florencia LIM, Scott R. SERSHEN

Publication number: 20210268141Abstract: Methods are provided for making freeze dried hydrogel and structures therefrom that may be introduced into a patient's body for medical applications. Precursor components are combined to initiate crosslinking. The combined precursor components are placed in a chilled tray, and allowed to crosslink to a desired level of complete crosslinking before and/or after being placed onto the tray. The partially crosslinked hydrogel is frozen and freeze dried. After freeze drying, the hydrogel is conditioned to substantially complete crosslinking, and formed into one or more structures, e.g., plugs, hemostatic, or other medical devices. For example, the hydrogel may be cut, machined, rolled, folded, compressed, and/or cored into that may be loaded into delivery devices that may be introduced into a body to implant or otherwise deliver the structures into the body, e.g., to seal a puncture or other passage through tissue.Type: ApplicationFiled: February 12, 2021Publication date: September 2, 2021Inventors: Amarpreet S. Sawhney, Steven L. Bennett, Suresh S. Pai, Scott R. Sershen, Fred H. Co

Patent number: 10213191Abstract: An apparatus for sealing a puncture through tissue to a vessel includes an elongate occlusion member including an expandable member, a cartridge carried on the occlusion member, and a sealant carried within the cartridge. The cartridge includes an outer member and a pusher member within the outer member. The sealant is disposed within the outer member adjacent the expandable member distal to the pusher member. During use, the occlusion member is introduced into a puncture until the expandable member and the sealant extend from the puncture into the vessel. The expandable member is expanded, and withdrawn until the expanded expandable member contacts the vessel wall, thereby withdrawing the sealant back into the puncture. The outer member is withdrawn to expose the sealant within the puncture, while the pusher member prevents removal of the sealant, and then the cartridge, occlusion member, and pusher member are successively removed.Type: GrantFiled: December 2, 2013Date of Patent: February 26, 2019Assignee: ACCESSCLOSURE, INC.Inventors: Farhad Khosravi, Suresh S.

Publication number: 20150005816Abstract: Apparatus and methods for sealing a puncture through tissue or otherwise treating a body lumen of a patient. The carrier includes at least one, but not all, of the adherent layer components required to form a tacky or sticky adherent layer on the carrier. The remaining adherent layer precursor(s) are delivered to the carrier in situ to form a sticky and/or tacky adherent layer on the carrier that enhances the attachment and retention of the carrier to tissue surrounding a target treatment location in which the carrier is delivered. The carrier may include hydrogel and/or other porous material, e.g., for releasing one or more agents carried by the carrier at the treatment location.Type: ApplicationFiled: September 15, 2014Publication date: January 1, 2015Inventors: Amarpreet S.
