Piston-actuated endoscopic steering system

Endoscopic steering apparatus is provided, including an endoscope (80) having distal (82) and proximal (98) ends thereof. In a preferred embodiment, at least one proximal cylinder (92) is disposed in a vicinity of the proximal end of the endoscope, and at least one proximal piston (94) is slidably coupled to the at least one proximal cylinder. This piston is typically manually driven. A first distal cylinder (88) is disposed at the distal end of the endoscope, and a first distal piston (90) is slidably coupled to the first distal cylinder. A second distal cylinder (88) is disposed at the distal end of the endoscope, and a second distal piston (90) is slidably coupled to the second distal cylinder. A first tube (86) is coupled to the first distal cylinder and to the at least one proximal cylinder, and a second tube (86) is coupled to the second distal cylinder and to the at least one proximal cylinder. A linkage (96) is disposed at the distal end of the endoscope and coupled to the first distal piston and to the second distal piston, such that displacement of at least one of the distal pistons causes displacement of the linkage and steering of the distal end of the endoscope.

Methods and apparatus for skin treatment

InactiveUS6920883B2Thermal damage is minimizedMinimizes and avoids damageDiagnosticsSurgical instruments for heatingDermisFace lifting
Methods and apparatus for electrosurgically treating human skin. The skin may be treated by applying thermal energy to the dermis to shrink the skin following liposuction, or to induce collagen deposition at the site of a wrinkle for wrinkle reduction or removal. In another embodiment, a method involves electrosurgically removing or modifying tissue in the head or neck to provide a face-lift or a neck-lift. In one embodiment, the working end of an electrosurgical instrument is positioned in at least close proximity to the dermis by approaching the dermis from the underside (reverse side) of the skin.

Wireless control device

A wireless control device includes a small, lightweight housing worn by an operator, for example on the operator's wrist, and a controlled device, for example a personal computer. Several optical emitters, preferably light emitting diodes operating in the infrared range, and several optical detectors are provided on the housing. At least one x-axis emitter-detector pair operates to detect an x-direction of a pointing motion or gesture, and at least one y-axis emitter-detector pair operates to detect a y-direction of a pointing motion or gesture. This motion can then be used to cause a response in the controlled device. For example, angles of the operator's hand at the wrist can be interpreted to induce motion of a cursor on a computer display. The device may also include a motion sensor, an environmental condition sensor, or a voice recognition sensor, and can also be adapted for gesture recognition and image scanning applications.

Expandable spinal implant apparatus and method of use

ActiveUS20100286779A1Decrease patient riskIncrease success rateBone implantSpinal implantsEngineeringCam
A spinal implant apparatus that is an expandable spacer including features to minimize or eliminate spacer cant or offset during and after completing the expansion process. The spacer includes a top component, a base component in engagement with the top component, and an expansion mechanism arranged to change the top component's position with respect to the base component. The mechanism for causing expansion may be a screw, a cam, a wedge or other form of distracting device. In one embodiment, the expandable spacer includes a base component with a set of towers and a top component with a set of corresponding silos, where the towers and silos are configured to minimize or eliminate tilt of the top component as it extends upwardly from the base component. In another embodiment, the spacer may include a stepped arrangement around the perimeter of the top component and the base component for engagement during height expansion with minimal canting or slippage. In another embodiment, the spacer may include texturing modification at the opposite ends of the longitudinal axis of the spacer to prevent tilting, slipping, or canting. Additionally, a portion of one or more exterior surfaces of the spacer may be textured, sawtoothed, dovetailed or the like to increase frictional intervertebral contact. The spacer may contain one or more passageways of selectable shape/dimension for bone growth through the spacer.

Risk identification system and methods

The present invention relates to a system and methods by which the risk associated with a new opportunity or new or ongoing relationship may be assessed. An example of such new opportunity or new relationship for which the present invention may be used to assess the risk is that concerning a potential new customer of a financial institution. The risk assessment of the present invention may be used to assess whether a new customer should be taken on as a customer and, if so, to what extent should the possible full range of account benefits be provided to the new customer. Other applications include assessing risk regarding a candidate for employment, assessing casualty loss and / or repayment risk in the insurance industry, and assessing risk in a landlord tenant relationship to determine whether or not to rent to the prospective tenant and if so, the amount of the security deposit.

System and method for application management through threshold events

A system, method, and program for managing applications on remote communication devices, such as cellular telephones, on a wireless communications network. A server on the wireless network stores application threshold event data and manages communication device resident applications through device interaction, such as limiting access to server-side applications, updating the application, or recording the occurrence of the threshold event for other application uses.

Outlet tube device for urinary drainage bag

An improved outlet tube device for a urinary drainage bag is disclosed wherein an outlet valve mechanism is contained with a rigid housing fixed securely to the drainage bag, rather than just being clamped to the outlet tubing, and thus cannot become separated from the bag. The outlet valve can be opened only by positive action on the part of the medical care personnel, thereby assuring that urine will be discharged only in a controlled manner. Further, because the valve mechanism does not require that a substantial length of tubing with a freely movable end be used in conjunction with the outlet port, there is no need to engage the free end of the tubing with a keeper. Thus the possibility of the tubing springing back to its straight configuration and flicking residual urine on the attending medical personnel is eliminated. In one embodiment the outlet tube device comprises a pinchcock-type valve which is fixedly mounted to the bag and which is normally operative to clamp off the outlet tube. In a second embodiment the outlet tube device comprises a syringetype fitting which is fixedly mounted to the bag. Depressing the syringe plunger closes the valve, and retracting the plunger opens the valve to permit fluid to be discharged through the outlet tube. In a third embodiment, a hose clamp is contained within a rigid housing and is selectively operative to clamp a hose to prevent fluid flow therethrough.
