A system for sealing a percutaneous puncture in a blood vessel in a living being and method of use thereof. The system includes a hemostatic closure, a blood vessel locator device for determining the position of the blood vessel via the percutaneous puncture, and a deployment instrument for deploying the closure within the puncture to seal the puncture. The vessel locator includes means for enabling blood from the vessel to flow therethrough so that the position of the vessel can be rapidly determined. Once the vessel has been located the deployment instrument, which includes a tubular carrier storing the closure, is extended into the puncture to deploy the closure. The closure basically comprises a radiopaque rigid anchor for location within the blood vessel, a compressed collagen plug for location within the puncture tract leading to the vessel, and a thin filament connecting the two in a pulley-like arrangement. The deployment instrument also includes a tamper which is used to mechanically deform the plug within the tract. Once the closure is positioned hemostasis occurs rapidly, thereby locking the closure in place.
A system for sealing a percutaneous incision or puncture in a blood vessel, the blood vessel having a wall, the incision or puncture comprising an opening in the wall of the blood vessel and a tract contiguous with the opening, said system comprising a closure and a removable tamper, said closure including a filament comprising a first filament portion and a second filament portion and a knot coupled to said second filament portion, said second filament portion being adapted to be extended through the tract and the wall of the blood vessel, said knot being adapted to be located within the tract, said first and second filament portions being adapted to have tension applied thereto, said tamper being arranged to be located within the tract and slidable along said first filament portion after said filament portions are extended within the tract to cause said knot to be moved with respect to said first filament portion and towards the opening in the wall of the blood vessel, said system effecting hemostasis adjacent the opening in the blood vessel.
A method for sealing a percutaneous incision or puncture in a blood vessel, the blood vessel having a wall, the incision or puncture comprising an opening in the wall of the blood vessel and a tract contiguous with the opening, said method comprising:
A system for sealing a percutaneous incision or puncture in a blood vessel, the blood vessel having a wall, the incision or puncture comprising an opening in the wall of the blood vessel and a tract contiguous with the opening, said system comprising a closure and a tamper, said closure including a first portion arranged to be located within the blood vessel and a second portion arranged to be located within the tract, said tamper having a resorbable portion, separate from said closure and arranged to be located within the tract and guidable through at least a portion of the tract to apply a force to said first portion of said closure when said first portion of said closure is located within the tract, said system effecting hemostasis adjacent the opening in the blood vessel.
A system for sealing a percutaneous incision or puncture in a blood vessel, the blood vessel having a wall, the incision or puncture comprising an opening in the wall of the blood vessel and a tract contiguous with the opening, said system comprising a closure and a removable tamper, said closure including a filament portion, said filament portion being adapted to be extended through the tract and the wall of the blood vessel and to have tension applied thereto, said tamper being arranged to be located within the tract and slidable along said filament portion after said filament portion is extended within the tract and tension applied to said filament portion to apply pressure to tissue adjacent the opening in the blood vessel, said system effecting hemostasis adjacent the opening in the blood vessel.
A method for sealing a percutaneous incision or puncture in a blood vessel, the blood vessel having a wall, the incision or puncture comprising an opening in the wall of the blood vessel and a tract contiguous with the opening, said method comprising:
