  • Patent number: 6964669
    Abstract: A linear delivery system and method for deployment of a detachable balloon at a target site in a patient in vivo is disclosed. The system includes a unitary sheath assembly having a retractable shaft and base, and a balloon delivery device configured for insertion through the lumen of the sheath assembly. The linear method of delivery overcomes disadvantages and limitations caused by undesirable movement of the assembly or separation of the catheter from the delivery system during inflation of the balloon. The linear delivery system further includes properties that increase the ease of use and stability of the device so as to reduce the effort required by the physician and discomfort experienced by the patient during deployment of a detachable balloon.

  • Publication number: 20050154412
    Abstract: An apparatus for treating an airway condition of a patient includes a handle sized to be hand-grasped by an operator and having an actuator mechanism to be selectively actuated by said operator. A needle is fixedly connected to the handle. The needle has an axially extending bore and a distal tip for penetrating into the airway tissue. An implant is disposed within said bore at the distal tip. The implant is formed of biocompatible material and is sized to be embedded within a tissue of said airway. The implant is ejected from the distal tip upon actuation of the actuator. The actuator has an indicator for indicating a position of the actuator and a lock for preventing movement of the actuator opposite a deployment direction.
