  • Patent number: 7998168
    Abstract: A drain tube stripper containing two handles pivotally joined at one end. The second end of each handle contains a roller. The rollers meet when the handles are pressed together. The handles are of unequal length. A drain tube, e.g., surgical drain, can be stripped of fluid and material buildup by placing the open rollers over the tube and pressing the handles together. The rollers thereby pinch the drain tube and the rollers allow the device to be moved along the drain tube pushing fluid and material ahead of the rollers. The drain tube stripper allows the tube to enter between the rollers from the side and exit from the side of the opposing handle. The tube drain stripper may also contain a guide component to minimize entanglement of the drain and the device is rolled along the drain tubing.

  • Patent number: 6872433
    Abstract: Micro-electromechanical tools for minimally invasive techniques including microsurgery. These tools utilize composite shape memory alloy (SMA), shape memory polymer (SMP) and combinations of SMA and SMP to produce catheter distal tips, actuators, etc., which are bistable. Applications for these structures include: 1) a method for reversible fine positioning of a catheter tip, 2) a method for reversible fine positioning of tools or therapeutic catheters by a guide catheter, 3) a method for bending articulation through the body's vasculature, 4) methods for controlled stent delivery, deployment, and repositioning, and 5) catheters with variable modulus, with vibration mode, with inchworm capability, and with articulated tips. These actuators and catheter tips are bistable and are opportune for in vivo usage because the materials are biocompatible and convenient for intravascular use as well as other minimal by invasive techniques.

  • Publication number: 20040267305
    Abstract: Flexible tube contents removers that are particular suitable for a variety of medical procedures include spaced arms supporting a pair of parallel spaced tapered rollers having spacing that is adjustable through finger pressure. One embodiment has the flexible tube extending through a hole in one support arm that directs the tube between the rollers. Another embodiment includes the rollers at an angle to a line normal to the longitudinal axis of the support arm so the tube extends along one side of the support arms and between the rollers. Stop surfaces restrict movement of the arms beyond a selected acute inside angle. A cam surface and resilient cut-out section on the arms serves as a bias to return the arms to a position of maximum spacing for the rollers when the finger pressure is removed.

  • Patent number: 6240630
    Abstract: A method and apparatus for loading deposit material, such as an embolic coil, into a shape memory polymer (SMP) gripping/release mechanism. The apparatus enables the application of uniform pressure to secure a grip by the SMP mechanism on the deposit material via differential pressure between, for example, vacuum within the SMP mechanism and hydrostatic water pressure on the exterior of the SMP mechanism. The SMP tubing material of the mechanism is heated to above the glass transformation temperature (Tg) while reshaping, and subsequently cooled to below Tg to freeze the shape. The heating and/or cooling may, for example, be provided by the same water applied for pressurization or the heating can be applied by optical fibers packaged to the SMP mechanism for directing a laser beam, for example, thereunto. At a point of use, the deposit material is released from the SMP mechanism by reheating the SMP material to above the temperature Tg whereby it returns to its initial shape.

  • Patent number: 6102933
    Abstract: Microfabricated therapeutic actuators are fabricated using a shape memory polymer (SMP), a polyurethane-based material that undergoes a phase transformation at a specified temperature (Tg). At a temperature above temperature Tg material is soft and can be easily reshaped into another configuration. As the temperature is lowered below temperature Tg the new shape is fixed and locked in as long as the material stays below temperature Tg. Upon reheating the material to a temperature above Tg, the material will return to its original shape. By the use of such SMP material, SMP microtubing can be used as a release actuator for the delivery of embolic coils through catheters into aneurysms, for example. The microtubing can be manufactured in various sizes and the phase change temperature Tg is determinate for an intended temperature target and intended use.
