Abstract: Medical devices and methods of using medical devices are disclosed. An example tissue retraction device includes a first engagement member having a first end and a second end, a second engagement member having a first end and a second end, a first elastic member attached to the second end of the first engagement member, and a first alignment member having a first end, a second end and a lumen extending therethrough. Further, the tissue retraction device has a first length, the first alignment member has a second length, the first elastic member extends within the lumen of the first alignment member and the second length of the first alignment member is less than or equal to the first length of the tissue retraction device.

Abstract: A medical device en-vivo positional determination system using a plurality of ultrasonic transducers for the time-of-flight (TOF) determination of absolute linear and angular positional information of the tool bit tip for the purposes of more accurate hand-held drilling, cutting, etc. on the work piece using digital code modulation schemes and digital signal processing (DSP) to provide a real-time display of the 3-linear position and 2-angular orientation of the tool bit (drill, scalpel).

Abstract: A beverage forming method and system in which a carafe with an associated magnetic element is positionable at a carafe receiving area. One of a protrusion and a first recess is associated with the carafe and the other of the protrusion and the first recess is associated with a housing. The housing includes a detector arranged to detect the presence of the magnetic element when the protrusion is inserted into the first recess. Beverage formation of an amount greater than a threshold volume is enabled when the detector detects the magnetic element.
