Abstract: A dual-wall integrated flange joint is provided. The integrated flange joint includes an inner wall having at least one inlet and at least one outlet, a flange extending radially outward from the inlet of the inner wall, and a collar extending from the flange in the direction of the inner wall and surrounding at least a portion of the inner wall. The integrated flange joint is formed of a single piece of material. Also, the collar at least partially defines an outer wall, and a volume between the collar and the inner wall at least partially defines an airgap.

Abstract: A system to facilitate sealing a puncture of a vessel includes an implant having first and second expandable sections, and a delivery device that includes an inner tube and a circumscribing outer tube. The outer tube defines a first lumen configured to retain the implant, and a second lumen configured to channel fluid from the vessel through a distal opening proximal to the implant. A pusher circumscribed at least partially by the outer tube is configured to compress the implant to selectively expand the first and second expandable sections. The outer tube is selectively retractable relative to the inner tube such that the first expandable section remains substantially within the first lumen and the second expandable section is positioned outside of the first lumen. The outer tube is further selectively retractable relative to the inner tube such that the first expandable section is positioned outside of the first lumen.

Abstract: A solid hemostatic composition for use within a biological tissue at an internal treatment site includes a biopolymer configured to cross-link with red blood cells at the site to facilitate clot formation at the site, a first thickener that includes (hydroxypropyl)methyl cellulose (HPMC), a second thickener that includes animal-derived gelatin, and a bioadhesive that includes a low molecular weight poly(lactide).

Abstract: A hemostatic device includes a first tube defining a first lumen configured to channel a fluid therethrough, and a second tube housing at least a portion of the first tube and at least partially defining a second lumen configured to retain a hemocoagulant agent therein. The second tube is moveable with respect to the first tube, such that the hemocoagulant agent is at least substantially retained within the second lumen when the second tube is in a first position, and the hemocoagulant agent is at least partially exposed when the second tube is in a second position.

Abstract: A hemostatic device for sealing a puncture of a vessel includes a first tube defining a first lumen. The first lumen is configured to receive a guidewire and a flow of a fluid therethrough. The hemostatic device also includes a second tube circumscribing at least a portion of the first tube and at least partially defining a second lumen. The hemostatic device further includes a substantially rigid stopper coupled to a distal end of the second tube. The stopper defines a stopper lumen that receives the first tube therethrough in an interference fit. A first opening is defined in a side wall of the first tube and positioned distally relative to the stopper. At least one injection groove defined in an outer surface of the stopper cooperates with the distal end of the second tube to define at least one second opening in flow communication with the second lumen.

Abstract: A method of inhibiting bleeding from an open surgical site includes mixing (i) a flowable gel solution comprising a biopolymer dissolved in a first solvent and (ii) a flowable hardener solution comprising a cross-linking agent dissolved in a second solvent to form a flowable hemostatic gel composition. The method also includes applying the flowable hemostatic gel composition to the open surgical site. The cross-linking agent links chains of the biopolymer together to form a solid hydrogel that inhibits bleeding from the surgical site.

Abstract: A hemostatic device for sealing a puncture of a vessel includes a first tube defining a first lumen, and a malecot coupled to the first tube. The malecot is selectively actuatable from a neutral configuration to a stopper configuration. The hemostatic device also includes a second tube circumscribing at least a portion of the first tube. The second tube at least partially defines a second lumen and a third lumen. The second tube includes a first opening in flow communication with the third lumen and positioned proximally relative to the malecot. The second tube is selectively orientable to at least partially expose a hemocoagulant agent retained in the second lumen.

Abstract: A closure system configured to facilitate hemostasis at a puncture of a vessel includes a delivery sheath that extends longitudinally from a proximal end to a distal end.

The introducer needle lumen is configured to receive a second guidewire therethrough.

Abstract: A flowable hemostatic gel composition is provided for use at a site of a defect within a biological tissue. The flowable hemostatic gel composition includes a flowable gel solution that includes a biopolymer dissolved in a first solvent. The biopolymer is configured to cross-link with red blood cells at the site to facilitate clot formation at the site. The flowable hemostatic gel composition also includes at least one additional active agent.

Abstract: A closure system configured to facilitate hemostasis at a puncture of a vessel includes a delivery sheath that extends longitudinally from a delivery sheath proximal end to a delivery sheath distal end. The delivery sheath defines a delivery sheath lumen extending therethrough and configured to receive a first guidewire therethrough.

The system further includes a stylet configured to be received through the delivery sheath lumen adjacent to the first guidewire. The stylet includes a stylet magnet configured to magnetically couple to a guidewire magnet of a second guidewire advanced through the secondary access site.
