  • Patent number: 6533761
    Abstract: A device for securing a catheter with respect to a patient's mouth that preferably includes a balloon that can be inflated within the patient's mouth on the exterior of the catheter, a bite block, and a shield. The balloon preferably immobilizes the catheter with respect to the securing device when inflated while permitting relative movement of the catheter and the securing device when deflated. The balloon preferably also prevents inadvertent withdrawal of the securing device from the patient's mouth when inflated while permitting withdrawal when deflated. The invention preferably includes a method for using such a securing device.

  • Patent number: 6527741
    Abstract: A resizable inflatable balloon, primarily for use with balloon catheters. The resizable inflatable balloon comprises a first portion and an adjacent second portion. The first portion is inflatable to a working diameter at a first pressure while the second portion does not substantially expand at the first pressure. The second portion does expand to the working diameter at a second pressure greater than the first pressure, so that subsequent inflation at the first pressure inflates the first portion and the second portion to the working diameter. The methods of resizing the inflatable members include placing the inflatable balloon in a mold and supplying inflation fluid to expand the second member to the working diameter. In practice, a catheter having the resizable inflatable balloon is guided through a patient's vasculature until the inflatable balloon is positioned in a desired region. Inflation fluid is supplied at the first pressure to inflate the first portion to the working diameter.

  • Patent number: 6503230
    Abstract: A syringe assembly includes a needle sheath that has a cavity that receives a needle cannula. The needle sheath can be formed of materials such as thermoplastic elastomers or plastics yet still be utilized with conventional gas sterilizing processes. The needle sheath includes a passage that permits the sterilizing gases to enter the cavity while preventing entry of microorganisms into the cavity. Thus, a syringe assembly is provided that facilitates sterilizing a needle after the needle sheath has been placed over the needle.

  • Patent number: 6468264
    Abstract: The invention provides a means of closed exchange of implanted medical device components. An exchanger is brought into contact with the implanted medical device in situ. The component is withdrawn from the implanted device and brought into a closed chamber of the exchanger. Without breaking the contact between implanted device and exchanger, the replacement component is then moved from its position in the exchanger, and inserted into the correct position in the implanted device. The surfaces of the implanted device are not brought into contact with the outside environment, thereby minimizing the possibility of introducing contaminants into the body during the exchange process. The invention is particularly useful for devices that are difficult to position and re-position, thus making it advantageous to exchange only an expended component, rather than the entire device.
