Abstract: A system, a closure, and method of use for sealing a percutaneous puncture in a blood vessel. The puncture includes an opening in the vessel wall and a tract leading to the opening. The system includes an introducer sheath and associated positioning device, a hemostatic puncture closure, and a deployment instrument. The positioning device enables the introducer sheath to be positioned at a desired position within the vessel. The deployment instrument includes a tubular carrier holding the closure. The closure comprises a rigid, e.g., radio-opaque, anchor, a compressed collagen plug, and a thin filament connecting the two in a-pulley-like arrangement. The instrument and introducer are used to introduce the closure into the puncture, with the anchor located within the artery and with the collagen plug within the puncture tract. A locking member is provided to hold the closure in place at its operative position, whereupon hemostasis occurs rapidly, thereby sealing the puncture.

Abstract: An instrument, a closure, and method of use for sealing an opening, e.g., a percutaneous incision or puncture, in a living being. The instrument includes a tubular carrier storing the closure. The carrier has a distally located free end to be extended through the opening. The closure comprises an anchoring portion, a sealing portion and a thin filament connected therebetween. The instrument is operated to eject the anchoring portion of the closure through the incision or puncture and to then draw that portion against the free end of the carrier. The instrument is then withdrawn to pull the anchoring portion of the closure against the tissue contiguous with the incision or puncture. Further withdrawing of the instrument draws the sealing portion of the closure out of the carrier, whereupon it moves with respect to the anchoring portion and into engagement with the tissue contiguous with the opening on the opposite side of the anchoring portion to seal it. Signals are produced to indicate proper operation.

Abstract: 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 extend 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.

Abstract: A system, a closure, and method of sealing a percutaneous puncture in an artery. The system includes a conventional introducer sheath, a hemostatic puncture closure, and an instrument for deploying the closure. The instrument includes a tubular carrier storing the closure. The carrier has a distally located free end to be extended through the puncture and its associated tract. The closure comprises a rigid anchor, a compressed collagen plug, and a thin filament connect the two in a pulley-like arrangement. The carrier is operated to eject the plug through the puncture and to then draw it against the free end of the introducer. The instrument and introducer are then withdrawn together to pull the anchor against the tissue contiguous with the puncture on the inside of the artery. Further withdrawing of the introducer and the instrument draws the plug out of the carrier into the puncture tract, whereupon it moves with respect to the anchor and into engagement with the outside of artery wall contiguous with the puncture to seal the puncture. The carrier also includes a tamper which is used to mechanically deform the plug within the tract. Once positioned the hemostasis occurs rapidly, thereby locking the closure device in place.

Abstract: Closure devices and methods of use for sealing a small, e.g., percutaneous, incisions or punctures. The closure device may take many forms an basically comprises a somewhat elongated plug having a deformable distal end portion including a free end to which a thin retraction filament is connected. The closure device is arranged to be introduced into the body of the being through the incision or puncture by an introducer so that the distal portion of the plug is located on one side of said tissue and its proximal portion is located on the other side of that tissue, with the filament extending through the incision or puncture. The filament is arranged to be grasped and pulled in the proximal direction to deform the distal portion of the plug so that it cannot pass back through the incision or puncture, whereupon the puncture or incision is sealed by the deformed distal portion of the plug. The distal portion of the plug is non-hemostatic so that when the closure is used to seal an incision or puncture in a blood vessel it will not produce any blood clots within the vessel.

Abstract: A catheter device for introduction into the body of a being to effect a procedure, e.g., lumen opening, therein. The catheter is an elongated member having a working head at its distal end and is sufficiently flexible and of small diameter to enable it to be located within the body of the being with the working head at the situs of the procedure. The catheter comprises an elongated drive wire extending through the catheter and motion transtator located at the distal end of the catheter. The wire is rotated at a high speed and the transtator translate that rotary motion into high speed reciprocation of the working head. In some embodiments, the motion transtator also causes the working head to be rotated at the same time it is reciprocated. In other embodiments, the working head is only reciprocated. In all cases, the motion of the working head is at a very high speed. The catheter also includes means to provide a fluid therethrough so that when the catheter is used to open a lumen, e.g., an arterial restriction caused by atherosclerotic plaque, the rotation of the working head causes the fluid to impact the artery wall.
