20090143765 | Device for Mixing and Delivering Fluids for Tissue Repair - A device for mixing and delivering a mixture of fluids to a target site includes a tube for containing the mixture. A compressible auger for mixing the fluids is movably disposed within the tube, one end of the auger being free at the distal end of the tube. A plunger is also movable within the tube in communication with the other end of the auger. When the plunger is moved axially within the tube the auger also moves axially and the auger is compressed to dispense the fluid. The mixing and delivery device can be used with an apparatus for the arthroscopic delivery of a tissue repair material to a repair site. The apparatus includes a first sheath and a second sheath removably attached to the first sheath for delivering the tissue repair material to the repair site. | 06-04-2009 |
20090197484 | CARBON NANOTUBE SPRING CONTACT STRUCTURES WITH MECHANICAL AND ELECTRICAL COMPONENTS - A composite spring contact structure includes a structural component and a conduction component distinct from each other and having differing mechanical and electrical characteristics. The structural component can include a group of carbon nanotubes. A mechanical characteristic of the composite spring contact structure can be dominated by a mechanical characteristic of the structural component, and an electrical characteristic of the composite spring contact structure can be dominated by an electrical characteristic of the conduction component. Composite spring contact structures can be used in probe cards and other electronic devices. Various ways of making contact structures are also disclosed. | 08-06-2009 |

20100139980 | BALL PISTON STEERING DEVICES AND METHODS OF USE - The invention provides ball piston steering devices and methods for use of ball piston devices. One aspect of the invention provides a ball piston steering device including: a sleeve in fluid communication with a fluid source and a ball received within the sleeve. The ball is movable within the sleeve from a recessed position and an extended position. | 06-10-2010 |
20110125107 | METHODS AND DEVICES FOR SENSING TISSUES AND TISSUE COMPARTMENTS - An apparatus provides feedback regarding the material in which tip of the apparatus is located as the tip is advance into matter of varying resistances. The apparatus responds to a change in pressure, force, or other parameter such that when the tip reaches matter of a certain resistance, a change in the parameter is sensed. The apparatus provides a driving force to a penetrating medical device, such as a needle, when the apparatus tip encounters material of high resistance. When the apparatus tip encounters a low resistance material, no further driving force is applied to the apparatus. An inner core may be advanced into the low resistance material for deployment of a gas or a liquid as desired. | 05-26-2011 |
20110179623 | Tapered Spiral Welded Structure - A method for creating a tapered spiral welded conical structure where the overall shape of the cone is first graphically slit axially and unwrapped, and then a series of construction arcs and lines are created to form the edge lines of a strip that can then be wrapped (rolled) to form a tapered conical structure. The edges of the spirally wound strip can be welded together, and a very large conical structure can thus be achieved. Various construction options are presented from a constant width strip to strip made from straight segments. Equations are given for the formation of the strips to enable those skilled in the art of spiral welded tubing to practice the invention. | 07-28-2011 |
20130055559 | STATIONARY SEMI-SOLID BATTERY MODULE AND METHOD OF MANUFACTURE - A method of manufacturing an electrochemical cell includes transferring an anode semi-solid suspension to an anode compartment defined at least in part by an anode current collector and an separator spaced apart from the anode collector. The method also includes transferring a cathode semi-solid suspension to a cathode compartment defined at least in part by a cathode current collector and the separator spaced apart from the cathode collector. The transferring of the anode semi-solid suspension to the anode compartment and the cathode semi-solid to the cathode compartment is such that a difference between a minimum distance and a maximum distance between the anode current collector and the separator is maintained within a predetermined tolerance. The method includes sealing the anode compartment and the cathode compartment. | 03-07-2013 |
20130074564 | TAPERED STRUCTURE CONSTRUCTION - Feeding stock used to form a tapered structure into a curving device such that each point on the stock undergoes rotational motion about a peak location of the tapered structure; and the stock meets a predecessor portion of stock along one or more adjacent edges. | 03-28-2013 |
20130193052 | Chromatography Columns - If one manufactures chromatography column tubes from plastic/thermoplastic or composite materials (such as polypropylene (PP), polyethylene (PE), polyamides, acetals, or glass-filled plastics, such as glass-fiber plastics) and secures at least one of two flow distributors within the column tube with a tight interference or press fit, the resulting chromatography columns reduce or avoid the formation of dead zones around the press fit flow distributor and have an infinitely adjustable packing medium volume, also known as the medium “bed height.” | 08-01-2013 |
20130261400 | Instrument Port For Minimally Invasive Cardiac Surgery - The instrument ports for introducing instruments into a surgical site that are disclosed herein include a port body having a channel running therethrough from a proximal end to a distal end, an instrument sleeve in slidable contact with the channel, creating a gap therebetween, and a fluid flow element for removing emboli efficiently from the instrument port, wherein the fluid flow element includes the gap. Disclosed fluid flow systems are for use in the disclosed instrument ports. Methods are also disclosed for removably securing an instrument sleeve to a port body by anchoring the instrument port to heart tissue, making at least one flood line in a channel, flushing out emboli, and performing surgery with the instrument port. | 10-03-2013 |
20140139250 | Contactor Devices With Carbon Nanotube Probes Embedded In A Flexible Film And Processes Of Making Such - Electrically conductive columns of intertwined carbon nanotubes embedded in a mass of material flexible, resilient electrically insulating material can be used as electrically conductive contact probes. The columns can extend between opposing sides of the mass of material. Terminals of a wiring substrate can extend into the columns and be electrically connected to an electrical interface to a tester that controls testing of a device under test. A pair of physically interlocked structures can coupling the mass of material to the wiring substrate. The pair can include a receptacle and a protrusion. | 05-22-2014 |
20140174760 | SYSTEM AND METHOD FOR CONVEYING - A technique facilitates conveyance of equipment along a wellbore or other tubular structure. A tractor is provided with a plurality of wheels oriented to engage a surrounding wall. Rotation of the wheels drives the tractor and causes longitudinal movement of the tractor with respect to the surrounding wall via a tangential force created between each wheel and the surrounding wall. Each wheel comprises teeth having a wheel tooth geometry which enhances cooperation with the surrounding wall. For example, the wheel tooth geometry may be designed to cooperate with the tangential force to push debris out of the teeth of each wheel during rotation of the wheel along the surrounding wall. In some applications, the wheel tooth geometry is designed to present a plurality of raised, rounded surfaces which engage the surrounding wall with a low stress impact. | 06-26-2014 |
