  • Patent number: 11344300
    Abstract: A surgical stapling device includes an end effector and a handle assembly operably coupled to the end effector. The end effector includes an anvil assembly and a cartridge assembly. The surgical stapling device also includes a specimen bag adhered to both the anvil assembly and the elongated support channel of the cartridge assembly. The specimen bag includes a drawstring within a drawstring housing. Once the surgical stapling device is inserted into a patient's body and the anvil assembly and the cartridge assembly are open, a tissue specimen is placed into the specimen bag. The anvil assembly and the cartridge assembly are then closed on the tissue specimen and the surgical stapling device is fired. The specimen bag then separates from the surgical stapling device and both the surgical stapling device and the specimen bag are removed from the patient.

  • Patent number: 11123068
    Abstract: A staple cartridge is adapted to enhance cell migration towards a wound site when staples are placed in tissue. In order to enhance cell migration, the staple cartridge is adapted to create an electrical potential within the tissue in the area of a wound or cut line. In embodiments, the electrical potential is created within the tissue by using staples in spaced rows formed of dissimilar metals having different anodic indexes to create a voltage gradient in the tissue to enhance cell migration toward the cut line.

  • Publication number: 20080037130
    Abstract: A control system for one or more electrochromic elements used in an outside electrochromic (OEC) mirror used in automobiles or other vehicular applications, to control the glare of both IEC elements used as a rearview mirror (20) as well as the OEC elements (24, 26) used as sideview mirrors (24, 26). An ambient light senor (129) and glare sensor (133) operate to determine a glare level used to control both IEC and OEC electrochromic elements. The drive circuits for the OEC's elements may be controlled so as to account for various factors such as tinted glass characteristics in the vehicle.

  • Publication number: 20070133827
    Abstract: A microphone includes one or more transducers positioned in a housing. Circuitry is coupled to the transducer for outputting an electrical signal such that the microphone has a main lobe directed forwardly and attenuates signals originating from the sides. The microphone transducers can advantageously include multiple transducers, which with the circuit produce a desired sensitivity pattern. The microphone can be employed in a vehicle accessory.

  • Publication number: 20070055543
    Abstract: A healthcare decision support system simulates effects of a change in a number of patients. A repository includes patient specific clinical and non-clinical data, comprising multiple medical record attributes of multiple patients. A simulation processor receives data representing multiple factors for adjusting a value representing number of patients in corresponding multiple associated subsets of the multiple patients. An individual subset comprises patients having a particular medical record attribute of a particular type. A calculation processor identifies patients common to different particular subsets, and calculates a change in a value representing number of patients common to the different particular subsets by calculating a product of factors associated with the different particular subsets.

  • Publication number: 20050068107
    Abstract: A sense transistor is placed in a current path between a reference voltage source and ground. The base terminal of the sense transistor is coupled to the base terminal of an amplifying transistor. Thus, current in the sense transistor corresponds to signal power output by the amplifying transistor. The sense current causes a sense voltage at the collector terminal of the sense transistor. This sense voltage is applied to one input of an error amplifier. The other error amplifier input receives a power control voltage. The error amplifier output is routed back to the base terminal of the amplifying transistor in a negative feedback loop, thereby keeping the power of the signal output by the amplifying transistor at a constant level. In some embodiments the error amplifier output is made independent of changes in the reference voltage. Multiple pairs of corresponding amplifying and sense transistors can be used.

  • Publication number: 20050002103
    Abstract: Equipment on automotive vehicle is controlled by a system including at least one semiconductor light sensor having variable sensitivity to light. Each light sensor generates a light signal indicative of the intensity of light incident on the light sensor. Control logic varies the sensitivity of the light sensor and generates equipment control signals based on received light signals. Sensitivity of light sensors may be varied by changing the integration time for producing charge from light incident on light transducers, by selecting between light transducers of different sensitivity within the light sensor, by using a light transducer with a sensitivity that is a function of the amount of incident light, and the like. Controlled equipment includes devices such as automatically dimming rearview mirrors, headlamps, and moisture removal means.

  • Patent number: 6030341
    Abstract: A method of assessing risk of an individual for a disease is disclosed. A level of a marker for the disease is detected, and the risk of disease is computed from a statistical analysis of the marker level distributions for tested normal and diseased populations, using multivariate distributions. The computed risk is compared to thresholds to triage the individual into a normal, borderline, or elevated risk group, and a course of action based on the risk group is determined. Memory storing a program for execution on a data processing system, as well as a computer system comprising said memory is also disclosed, the memory comprising a receiver for signals representative of levels of a marker for the disease; a central processing unit for computing risk of disease from one or more levels of the marker, and for comparing the computed risk to thresholds to triage the individual; and storage medium for the marker levels for subsequent computations of risk of disease.
