  • Patent number: 6346091
    Abstract: Apparatus and method are disclosed by which a hollow distal end portion of a wire may be deposited at selected sites in body passageways. The apparatus includes an elongate wire (solid or hollow) having a distal end section for detachment and delivery to a target location, the wire also having a discontinuity located rearwardly of the distal end section for rupturing when vibrational energy is applied to the wire. The discontinuities may take the form of cuts formed in the wire, reduced diameter sections in the wire, adhesive, welded or soldered couplings between the wire and the distal end section, or the wire transitioning from the wire to a large mass disposed on the distal end section. A catheter is coupled to or surrounds the elongate wire to deliver therapeutic liquid to a target body location.

  • Patent number: 6293959
    Abstract: A balloon catheter and stent delivery system for medical treatment of a patient includes a balloon inflatable to an inflated shape having a cylindrical working portion, and a deflated shape that is temporarily reformed to enhance longitudinal retention of the stent while the catheter system is advanced or withdrawn, with various additional features.

  • Patent number: 6277095
    Abstract: A fluid delivery device for infusing medicinal fluids at a precisely controlled rate which includes adapter sleeve means for insuring that only a proper medicament can be used to fill the fluid reservoir of the apparatus. More particularly, the apparatus includes a unique polarity adapter that will mate only with a particular delivery device and positively prevent filling the reservoir of the device with a medicament that is incompatible with the delivery profile of the device. In one form of the invention, the polarity adapter includes a novel double-ended cannula that is carried within the polarity adapter and controls filling of the fluid reservoir.

  • Patent number: 6210366
    Abstract: A vascular access device is provided which can be used for chronic venous or organ access. When implanted, the device facilitates repeated intermittent infusions of medical treatment while reducing the risk of infection at the implant site. The vascular access device comprises an elongated body and a delivery tube coupled to the elongated body for delivering the medical treatment to a preselected site in a patient's body, which permits subcutaneous implanting of the device with a minimally invasive procedure. A sheath and a dilator are adapted to form an access tunnel in the patient's body commensurate in configuration with the elongated body of the device. A guide wire is provided to guide the sheath and dilator from a first opening to a second opening in the patient's body. The introduction of the sheath eases the placement of the device and reduces access site trauma to the vein, organ, or any other location in the body to which the medicine or therapy is to be applied.
