20080300533 | Disposable aspirator cassette - An aspirator cassette includes a housing having first and second ends sealed off by first and second end caps, respectively. A partition mechanism is enclosed within the housing for dividing its internal volume into first and second regions. First and second fluid flow ports are mounted on the first and second end caps, respectively, to provide fluid flow paths into and from the first and second regions, respectively. When the first region is filled with liquid, its associated first port is connected to a vacuum source for sucking the liquid out of the region, whereby as the liquid is removed, the partition mechanism responds by decreasing the volume of the first region, and increasing the volume of the second region causing its second port to draw a vacuum for sucking fluid from an aspiration device connected to the second port. | 12-04-2008 |
20100004642 | Selectively bendable laser fiber for surgical laser probe - A surgical laser probe includes a handpiece having a proximal end for receiving an optical fiber into a centrally located throughhole, and a distal end through which the centrally located throughhole extends and varies in diameter. An end portion of a stainless steel tube is rigidly secured within the hole in the distal end of the handpiece. An end portion of a polyimide bendable tube is secured to the free end of the stainless steel tube. A slideable finger pad is installed in a slotway of the handpiece and rigidly secured to one end of a Nitinol wire. The optical fiber is extended through the handpiece, the stainless steel tube, and into the bendable tube, with the free end of the optical fiber terminated at the free end of the polyimide bendable tube. As the finger pad is slid toward the distal end of the handpiece, the free end of the Nitinol wire is increasingly moved into the bendable tube for increasingly bending the bendable tube and optical fiber away from the longitudinal axis of the stainless steel tube. | 01-07-2010 |

20080257658 | Method and Apparatus for Adjusting a Lever Actuated Hydraulic Disc Brake Master Cylinder - A method of adjusting a lever actuated bicycle hydraulic disc brake master cylinder. The disc brake master cylinder has a housing defining a cylinder having first and second ends and a port communicating with a fluid reservoir between the first and second ends. A piston is received in the cylinder and the piston has a seal having a leading seal edge between the piston and the cylinder. The lever is operatively associated with the piston to move the piston from an unactuated position with the leading seal edge a select distance between the port and the first end of the cylinder to an actuated position between the port and the second end of the cylinder. The method of adjusting the lever actuated bicycle hydraulic disc brake master cylinder comprises varying the select distance between the port and leading edge of the seal with the piston in the unactuated position and providing a stop preventing the leading edge of the seal from moving between the port and the second end of the seal as a result of varying the select distance between the port and the leading edge of the seal with the piston in the unactuated position. | 10-23-2008 |
20080271446 | Master Cylinder Lever with Variable Dead Band and Variable Reach Adjustment Independent of the Dead Band Adjustment - A master cylinder for a bicycle hydraulic disc brake comprises a housing defining a cylinder, the cylinder having a first and a second end along its axis. A hydraulic fluid reservoir has a port between the hydraulic fluid reservoir and the cylinder, the port having an opening between the first and second cylinder ends. A piston having a seal resides in the cylinder with the seal between the piston and the cylinder. The seal has a leading seal edge with the leading seal edge being movable solely between the first cylinder and the port opening to vary the dead band distance between the leading seal edge and the port opening with the piston in a starting position. A lever is pivotably associated with the housing and operatively associated with the piston for moving the piston within the cylinder between the starting and a pressurized position as the lever is actuated between a rest position and an actuated position. A reach adjustment is operatively associated with the lever for varying the rest position of the lever relative to the master cylinder housing independent of movement of the leading seal edge relative to the port as the reach adjustment varies the rest position of the lever. | 11-06-2008 |
20090000878 | Method of Varying a Rest Position and a Length of an Actuation Arc of a Lever in a Hydraulic Disc Brake System - A method of varying a rest position and a length of an actuation arc of a lever in a hydraulic disc brake system. The hydraulic disc brake system comprises a master cylinder including a cylinder having a first end and second end and a port communicating with a hydraulic fluid reservoir between the first and the second cylinder ends. A piston is received in the cylinder. The piston has a seal between the cylinder and the piston and the piston is movable within the cylinder by a lever operatively associated therewith to selectively pressurize hydraulic fluid within the cylinder by moving the seal between the port and the second end of the cylinder.
