  • Patent number: 6796996
    Abstract: A shape-retaining bag having a front and a back connected to each other to define a chamber between for housing and retaining a fill material within a plurality of cells within the chamber which are made of a plurality of walls and one or more flow diverters adjacent to the cells and on the ends of the walls. A passageway is on a fill-side with a second passageway on an opposing side, each passageway extending approximately from one end side to another end side of the bag. As fill material is introduced into the chamber, it passes through the cells and the passageways in a fashion dictated by the cells and by the flow diverters until the bag is filled. The configuration of the various cells and flow diverters permit the bag to retain its shape notwithstanding the fill material within.

  • Patent number: 6786897
    Abstract: A temperature sensing device for attachment to a powered surgical instrument operating a workpiece such as a bur. The device is a thermochromic element which may be embodied as a paint or a thermal insulating device. The device embodiment is in the form of a thermoplastic, elastomeric material which changes color at a predetermined temperature and is formed in a shape adapted to enable the device to be affixed to the distal end of the instrument, adjacent the collet connecting the workpiece to the instrument. The device is attached in a contiguous manner so frictional heat generated by moving parts of the instrument may be conducted through contiguous surfaces of the instrument and the device. The thermochromic element provides a visual indication of the temperature of a portion of the instrument when the temperature exceeds a predetermined level.

  • Patent number: 6689155
    Abstract: A therapy device for providing heated air to the upper body of a patient and a method of making and using the therapy device have been provided. The therapy device is an inflatable U-shaped tube mounted on a base sheet and having a cover sheet. The patient is placed on the base sheet with the patient's head located between the legs of the tube. The cover sheet is placed over the patient's face. A heated air supply tube is connected to the tube and the heated air inflates the tube and heated air is forced out of the exhaust ports of the tube, thereby providing an environment in which a portion of the patient's body is heated. In one embodiment the exhaust ports are slits cut into the tube sheet material, and the slits are parallel to a tangent line of the tube's sealed edge. The method of fabricating the therapy device includes forming the individual pieces, attaching the tube sheets to form a tube, lancing the tube to form exhaust ports, and attaching the remaining pieces.

  • Patent number: 6676690
    Abstract: An apparatus having an inflatable balloon near a distal end of a multi-lumen catheter, with a plurality of blood flow passageways formed through the interior of the balloon from a proximal face of the inflated balloon to a distal face of the inflated balloon. A heat transfer solution is introduced through a supply lumen of the catheter to inflate the balloon in a selected blood vessel; this allows blood to flow through the blood flow passageways of the balloon, from one exterior face of the balloon to another exterior face. The heat transfer solution continues to circulate around the blood flow passageways inside the balloon, to change the blood temperature, eventually exiting the balloon through a return lumen of the catheter.

  • Patent number: 6673099
    Abstract: Methods and devices for preventing a change in the core body temperature of a mammal under cold conditions are provided. In the subject methods, a requirement for thermal energy input in said mammal is first detected. In response to the detection of this requirement for thermal energy input, a surface of a portion of the mammal is contacted with a warm temperature medium under negative pressure conditions for a period of time sufficient to introduce thermal energy into the core body of the mammal. The subject devices include at least a means for detecting a requirement for thermal energy input and a means for contacting a surface of the mammal with a warm temperature medium under negative pressure conditions. The subject methods and devices find use in a variety of applications, and are particularly suited for use in maintaining the core body temperature of a mammal substantially constant under cold conditions for an extended period of time.

  • Patent number: 6666818
    Abstract: A modular endoscope valve assembly is releasably mounted on the handpiece of an endoscope. This valve assembly includes an inlet port, an outlet port, and a valve manually operable selectively to block and to allow the flow of irrigation fluid from the inlet port to the outlet port. The valve assembly is releasably held to the handpiece of the endoscope by a mechanical fastener such as a pressure-sensitive adhesive, a strap, a snap lock, or otherwise. Once the valve assembly is releasably mounted to the handpiece, the physician using the endoscope can manually control the flow of irrigation fluid, and optionally suction, with the same hand as the one that supports the handpiece, thereby leaving the other hand of the physician free for surgical procedures. The modular valve assembly of this invention can be used with the widest variety of endoscopes, including flexible, rigid and semi rigid ureteroscopes as well as various percutaneous endoscopes.
