摘要： A blood vessel access closure device includes an inner blood vessel wall support member and an outer blood vessel wall support member. The closure device also includes a deployment member and an electrode. The deployment member is configured to draw the inner and outer blood vessel wall support members towards each other when the inner and outer blood vessel wall members are deployed on opposite sides of a blood vessel wall during closure of a hole in the blood vessel wall. The electrode is configured to be attached to the deployment member and configured to be used to measure impedance.

摘要： A method and prosthesis is provided for percutaneous repair of an anatomical defect, such as an iguinal hernia. The method involves percutaneously accessing the inguinal canal of a patient. Following hernia reduction, if required, the hernia defect may be accessed and repaired percutaneously from within the inguinal canal. An implantable prosthesis may be percutaneously delivered into the inguinal canal. The prosthesis may be advanced along the inguinal canal from the percutaneous entry location to the defect site, where it may be developed over and/or within the defect. A biocompatible foam material may be percutaneously delivered into the inguinal canal to reduce and/or repair the hernia defect. The foam may fill and solidify in the canal to prevent abdominal viscera from reentering the canal. Ablative therapy may be performed within the inguinal canal to cause a fibrotic response resulting in scar tissue formation and/or tissue shrinkage that narrows the canal.

摘要： An apparatus for sealing a puncture includes a cartridge, a pusher member, a sealant, and a tamping device on a proximal end of the cartridge. During use, the cartridge, sealant, and pusher member are advanced over a positioning member and into the puncture by advancing a cartridge hub carrying the tamping device. When further distal advancement of the cartridge is limited, the cartridge hub is further advanced, activating the tamping device, and causing the pusher member to advance relative to the sealant to compress the sealant within the puncture.

摘要： Devices for closing a passage through tissue communicating with a body lumen. The device may include an elongate body, a sheath disposed at the distal end of the device for disposition within a body lumen, a hollow needle disposed within a needle lumen of the body, the needle being selectively advanceable through the needle lumen, a suture-anchor ejection mandrel disposed within the hollow needle that is also selectively advanceable through the hollow needle, a suture-anchor and suture disposed within the hollow needle, a distal end of the suture attached to the suture anchor for ejection out the hollow needle by the mandrel. A needle guide disposed between the sheath and proximal end of the body may include a needle port through which the needle can exit. A hemostatic plug is disposed over the needle port so as to be penetrated by the needle upon exiting the port.

摘要： A bioadhesive delivery catheter includes a manifold, a dual lumen tube, and a mixing member. The manifold includes a delivery device passage and an injection port. The tube is insertable into the delivery device passage and includes first and second lumens positioned side-by-side. The first lumen extends proximal of the second lumen within the delivery device passage, and the second lumen is in flow communication with the injection port. The mixing member is positioned between a proximal inlet of the injection port and the second lumen and is configured to help mix a bioadhesive material that is delivered through the injection port into the second lumen.

摘要： Closure devices for sealing a puncture and methods of sealing a puncture are described herein. A closure device may be used to position a sealant in a puncture. The sealant may be provided in a sheath which is retracted to expose the sealant in the puncture. A support member may be advanced to compress the sealant. The device may have a lock that prevents the support member from advancing prematurely. The lock may be unlocked when the sheath is at least partially retracted. The device may have an actuator that controls movement of the sheath and the support member. The lock may remain in a locked position until the sheath is at least partially retracted.

摘要： A vascular closure device includes a vessel locating device, a sealant delivery device, a detachable sealing tip, and a suture. The vessel locating device includes an expandable portion configured to extend through and temporarily seal a vessel puncture from within a vessel. The sealant delivery device is configured to deliver a first volume of flowable sealant to the vessel puncture along an exterior of the vessel. The detachable sealing tip is carried at a distal end of the vessel locating device. The suture is connected to and extends proximally from the detachable sealing tip. The detachable sealing tip is configured for release within the first volume of flowable sealant upon withdrawal of the vessel locating device through the first volume of flowable sealant. The suture is anchored at a location proximal of the detachable sealing tip.
