Ultrasonic surgical system and method

An ultrasonic surgical system has an ultrasonic unit including an instrument operatively connected to an ultrasonic generator, wherein the instrument has an ultrasonic end effector on the distal end of a shaft. The system further includes a positioning unit including a movable arm adapted for releasably holding the instrument, whereby an operator may direct the positioning unit to position the end effector at a surgical site inside a body cavity of a patient for performing a plurality of surgical tasks. The system further includes a control unit operatively connected to the ultrasonic and positioning units, wherein the control unit is programmable with a surgical subroutine for performing the surgical tasks. The system further includes a user interface operatively connected to the control unit for initiating an operative cycle of the surgical subroutine such that the surgical tasks are automatically performed during the operative cycle.

Flexible instrument

A medical probe and medical system are provided. The medical probe comprises an elongated shaft, a plurality of electromagnetic elements spaced along the elongated shaft, and a plurality of wires extending through the elongated shaft and configured for energizing the electromagnetic elements that actuate a controlled bending of the elongated shaft. The medical system may comprise the medical probe and a controller configured for energizing the electromagnetic elements via the wires to actuate the controlled bending of the elongated shaft. The medical system may optionally comprise a user interface configured for conveying commands to the controller, in which case, the controller will be configured for energizing the electromagnetic elements via the wires to actuate a controlled bending of the elongated shaft in response to the commands.

Analyte sensors having a signal-to-noise ratio substantially unaffected by non-constant noise

Systems and methods of use involving sensors having a signal-to-noise ratio that is substantially unaffected by non-constant noise are provided for continuous analyte measurement in a host. In some embodiments, a continuous analyte measurement system is configured to be wholly, transcutaneously, intravascularly or extracorporeally implanted.

Flexible instrument

A method of performing a medical procedure on a patient comprises conveying control signals from a remote controller to a drive unit, intravenously introducing the catheter into a heart of the patient (e.g., via the vena cava into the right atrium), and creating a puncture within a wall between two chambers (e.g., the left and right atria) of the heart. The method further comprises creating a puncture within a wall between two chambers of the heart, and operating the drive unit in accordance with the control signals to advance a working catheter within the guide catheter through the puncture.

Graphical scroll wheel

A touch screen interface including a display screen, a touch sensor device, and a processor coupled to the display screen and the touch sensor is described. The touch sensor device is adapted to sense object motion in a sensing region that overlaps at least part of the display screen. The processor is adapted to cause a scroll wheel that indicates a scrolling path to appear on the display screen selectively, such as in response to the touch sensor sensing object motion that corresponds to a scrolling initiation gesture. The processor is further adapted to cause scrolling on a display screen selectively, such as in response to the touch sensor sensing subsequent object motion along the scrolling path after the touch sensor has sensed the object motion corresponding to the scrolling initiation gesture.

Catheter delivered valve having a barrier to provide an enhanced seal

A system for treating abnormalities of the right ventricular outflow tract includes a prosthetic valve device having a barrier material contacting at least a portion of the outer surface of the valve device. One embodiment of the invention includes a barrier member attached to the exterior surface of the valve device. Another embodiment includes a barrier material that is injected within the vascular system. Yet another embodiment of the invention includes a method for replacing a pulmonary valve that includes forming a barrier around the outer surface of a replacement valve and preventing blood flow around the replacement valve.

Simplified pitch doubling process flow

A method for fabricating a semiconductor device comprises patterning a layer of photoresist material to form a plurality of mandrels. The method further comprises depositing an oxide material over the plurality of mandrels by an atomic layer deposition (ALD) process. The method further comprises anisotropically etching the oxide material from exposed horizontal surfaces. The method further comprises selectively etching photoresist material.

Malware modeling detection system and method for mobile platforms

A system and method for detecting malware by modeling the behavior of malware and comparing a suspect executable with the model. The system and method extracts feature elements from malware-infected applications, groups the feature elements into feature sets, and develops rules describing a malicious probability relationship between the feature elements. Using malware-free and malware-infected applications as training data, the system and method heuristically trains the rules and creates a probability model for identifying malware. To detect malware, the system and method scans the suspect executable for feature sets and applies the results to the probability model to determine the probability that the suspect executable is malware-infected.

Haptic device with indirect haptic feedback

A haptic device provides indirect haptic feedback and virtual texture sensations to a user by modulation of friction of a touch surface of the device in response to one or more sensed parameters and/or time. The sensed parameters can include, but are not limited to, sensed position of the user's finger, derivatives of sensed finger position such as velocity and/or acceleration, sensed finger pressure, and/or sensed direction of motion of the finger. The touch surface is adapted to be touched by a user's bare finger, thumb or other appendage and/or by an instrument such as a stylus held by the user.

System and Method for Managing Malware Protection on Mobile Devices

A system and method for providing malware protection on client mobile platforms in a mobile network. The system and method manages the malware scanning agents of the client mobile platforms from a management server using a device independent secure management protocol. The management server downloads new malware definitions to client mobile platforms and remotely initiates malware scanning on the client mobile platforms.
