An introducer cartridge for an embolization device for use with a delivery catheter having a proximal end with a hub mounted thereon and having a conical recess therein. The introducer cartridge comprises a flexible elongate tubular member formed of a clear plastic and has a flow passage extending therethrough and has proximal and distal extremities. The distal extremity is tapered and a hub formed of clear plastic is secured to the proximal extremity of the flexible elongate tubular member. The hub of the introducer cartridge has a conical recess therein having proximal and distal extremities. The distal extremity of the conical recess has a diameter which is slightly less than the diameter of the flow passage in the elongate tubular member.
An embolization device comprising an elongate coil having a plurality of turns formed of a metal which is opaque to x-rays and having rounded ends and a first group of fibers, said first group of fibers having an intermediate portion and first and second end portions, said intermediate portion extending interiorly of the coil and each of said first and second end portions extending outwardly of the coil through two adjacent turns, said first and second end portions being spaced apart by at least three turns, the ends of the fibers of the first and second end portions of each first group being free to move, said first group of fibers being free of knots.
An introducer cartridge for an embolization device for use with a delivery catheter having a proximal end with a hub mounted thereon and having a conical recess therein, said introducer cartridge comprising a flexible elongate tubular member formed of a clear plastic and having a flow passage extending therethrough and having proximal and distal extremities, said flow passage having a diameter, said distal extremity being tapered and a hub formed of plastic secured to the proximal extremity of the flexible elongate tubular member, said hub of the introducer cartridge having a conical recess free of obstructions therein with a proximal extremity and with a distal extremity, the distal extremity of the conical recess terminating at the proximal extremity of the flexible elongate tubular member and having a diameter which is less than the diameter of the flow passage in the flexible elongate tubular member to aid in preventing the embolization device from hanging up in the introducer cartridge and to prevent damage to the embolization device.
The combination of an introducer cartridge together with a delivery catheter, said introducer cartridge comprising a flexible elongate tubular member formed of a clear plastic and having a flow passage extending therethrough and having proximal and distal extremities, said flow passage having a diameter, said distal extremity being tapered and an introducer cartridge hub formed of clear plastic secured to the proximal extremity of the flexible elongate tubular member, said introducer cartridge hub having a conical recess therein with a proximal extremity and with a distal extremity, the distal extremity of the conical recess having a diameter which is slightly less than the diameter of the flow passage in the flexible elongate tubular member, said delivery catheter having a proximal end and having a delivery catheter hub mounted on the proximal end, said delivery catheter hub having a conical recess therein, said conical recess in the delivery catheter hub being sized so that the tapered distal extremity of the introducer cartridge engages and seats within the conical recess of the delivery catheter hub and is frictionally retained therein, said introducer cartridge hub being provided with a longitudinal axis and said introducer cartridge hub being formed with first and second outwardly and diametrically extending wings lying in a plane extending perpendicular to the longitudinal axis of the introducer cartridge hub, said wings having a width which does not substantially interfere with viewing of the conical recess in the introducer cartridge hub.
The combination of an introducer cartridge together with a delivery catheter, said introducer cartridge comprising a flexible elongate tubular member formed of a clear plastic and having a flow passage extending therethrough and having proximal and distal extremities, said flow passage having a diameter, said distal extremity being tapered and an introducer cartridge hub formed of clear plastic secured to the proximal extremity of the flexible elongate tubular member, said introducer cartridge hub having a conical recess therein with a proximal extremity and with a distal extremity, the distal extremity of the conical recess having a diameter which is slightly less than the diameter of the flow passage in the flexible elongate tubular member, said delivery catheter having a proximal end, a delivery catheter hub mounted on the proximal end, said delivery catheter hub having a conical recess therein, said conical recess in the delivery catheter hub being sized so that the tapered distal extremity of the introducer cartridge engages and seats within the conical recess of the delivery catheter hub and is frictionally retained therein, said delivery catheter hub being formed of a transparent material and having proximal and distal extremities and a longitudinal axis, the hub including a pair of wings extending diametrically outwardly and lying in a plane which is coincident with the longitudinal axis of the delivery catheter hub, said wings of the delivery catheter hub being mounted on the distal extremity remote from the conical recess in the delivery catheter hub.
