摘要： Apparatus for sealing a puncture through tissue to a blood vessel includes a cartridge including a proximal end, a distal end sized for insertion into a puncture, and a lumen extending therebetween. A bioabsorbable plug is disposed within the lumen adjacent the distal end, and an anchoring element is disposed within the lumen proximal to the plug. A pusher member is disposed within the lumen for deploying the plug and anchoring element out the distal end of the cartridge. The plug may be formed from lyophilized hydrogel and the anchoring element may be formed from air-dried hydrogel, the anchoring element hydrating slower than the plug when exposed to an aqueous environment. During use, the plug and anchoring element are delivered into the puncture, the plug is cinched against the vessel wall. Protrusions on the anchoring element engage tissue surrounding the puncture to prevent proximal movement of the plug.

摘要： Apparatus for delivering a sleeve into a puncture through tissue includes a tubular sheath including a lumen extending between its proximal end and an opening in its distal end. The sleeve includes a hub on a first end thereof disposed adjacent the distal end of the sheath, and a second end extending into the opening and lumen of the sheath. The hub is slidable along an exterior of the sheath for drawing the sleeve out of the opening and along an exterior of the sheath. During use, a guide wire is placed through the puncture into a blood vessel, and sealing compound is introduced into the puncture around the guide wire. The sheath is advanced into the puncture over the guidewire while maintaining the hub adjacent the patient's skin, causing the sleeve to be deployed from the sheath and line the puncture as the sheath is advanced into the puncture.

摘要： 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 The expandable member is expanded, and withdrawn until the expanded expandable member contacts the vessel wall, thereby withdrawing the sealant back into the puncture.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.

摘要： Apparatus for sealing a puncture communicating with a blood vessel includes a porous carrier formed from lyophilized hydrogel or other material. The plug may include at least first and second hydrogel precursors and a pH adjusting agent carried by the porous carrier in an unreactive state prior to exposure to an aqueous physiological environment. Once exposed to bodily fluids, the carrier expands as the lyophilized material hydrates to enhance and facilitate rapid hemostasis of the puncture. When the plug is placed into the puncture, the natural wetting of the plug by bodily fluids (e.g., blood) causes the first and second precursors to react and cross-link into an adhesive or “sticky” hydrogel that aids in retaining the plug in place within the puncture.

摘要： Apparatus for sealing a puncture includes an elongate occlusion member having a balloon attached to distal ends of telescoping inner and outer members. A housing on the proximal end of the outer member includes a piston coupled to the inner member and slidable within a chamber communicating with a fluid reservoir. A switch on the housing is actuated to direct fluid from the reservoir through the outer member into the balloon to expand the balloon and into the chamber to move the piston and pull the inner member, shortening the balloon as it expands. During use, the distal end of the occlusion member is introduced into a puncture communicating with a vessel until the collapsed balloon is disposed within the vessel. The balloon is expanded, and a tensioner is connected to the housing to apply a proximal force holding the balloon against the vessel wall to seal the puncture.

摘要： An apparatus for sealing a puncture extending through tissue to a blood vessel includes a guidewire including an expandable tamp, a retaining sheath for covering the tamp, and a delivery sheath including a primary lumen for receiving the guidewire therethrough and a secondary lumen for delivering sealing compound into the puncture. The guidewire is advanced into the puncture with the tamp in a contracted condition, the tamp is expanded within the vessel after retracting the retaining sheath, and the guidewire is retracted to seal the puncture from the vessel. The delivery sheath is advanced over the guidewire, and sealing compound is introduced into the puncture through the delivery sheath. After introducing the sealing compound, the delivery sheath is removed, and an introducer sheath is advanced over the guidewire to provide access to perform a medical procedure via the vessel after removing the guidewire.

摘要： Apparatus and methods are provided for sealing a puncture extending through tissue to a blood vessel. A delivery sheath is introduced-into the puncture, and a sealing compound, e.g., precursor polymers that mix to create a hydrogel, is introduced through the delivery sheath into the puncture. The delivery sheath is then removed, an introducer sheath is advanced through the puncture into the vessel, and instruments are introduced through the introducer sheath into the vessel to perform a medical procedure. After completing the procedure, the introducer sheath is withdrawn. The sealing compound may expand into the puncture and/or tissue recoil of the surrounding tissue may cause the sealing compound to at least partially occlude the puncture to facilitate sealing and/or hemostasis.

摘要： Apparatus and methods are provided for flaring a stent deployed within a branch vessel including an ostium communicating with a main vessel, a first end of the stent extending at least partially from the branch. A catheter is provided that includes a first balloon carried on its distal end, and a second balloon that includes a distal section overlying at least a portion of the first balloon and a proximal section. The catheter distal end is introduced into the main vessel and positioned through the ostium and stent into the branch until the first balloon is disposed within the stent. The first balloon is expanded to anchor the stent, and the second balloon is expanded to flare the first end of the stent. Optionally, the first balloon is expanded further, e.g., to expand the stent within the branch body lumen and/or dilate the lesion.
