Apparatus and methods for delivering sealing materials during a percutaneous procedure to facilitate hemostasis
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.
