Devices, systems, and methods are provided for accessing the interior of the heart and performing procedures therein while the heart is beating. In one embodiment, a tubular access device having an inner lumen is provided for positioning through a penetration in a muscular wall of the heart, the access device having a means for sealing within the penetration to inhibit leakage of blood through the penetration. The sealing means may comprise a balloon or flange on the access device, or a suture placed in the heart wall to gather the heart tissue against the access device. An obturator is removably positionable in the inner lumen of the access device, the obturator having a cutting means at its distal end for penetrating the muscular wall of the heart. The access device is preferably positioned through an intercostal space and through the muscular wall of the heart. Elongated instruments may be introduced through the tubular access device into an interior chamber of the heart to perform procedures such as septal defect repair and electrophysiological mapping and ablation. A method of septal defect repair includes positioning a tubular access device percutaneously through an intercostal space and through a penetration in a muscular wall of the heart, passing one or more instruments through an inner lumen of the tubular access device into an interior chamber of the heart, and using the instruments to close the septal defect. Devices and methods for closing the septal defect with either sutures or with patch-type devices are disclosed.

Decision information system for drug delivery devices

Decision information systems, methods, and computer programs for better informing decisions to use multiple drugs in drug delivery devices, including implantable devices, for drug administration. Executable computer programs and logic embodying methods of the invention can calculate consistent multiple drug mixture amounts and drug delivery flow rates. One program accepts user input indicating a desired first drug dose rate, an initial first drug concentration, a desired second drug dose rate, an initial second drug concentration, and the reservoir size of the drug delivery device. The program method calculates a first drug amount and a second drug amount to combine in a mixture as well as a first drug true concentration in the mixture. The drugs can be mixed consistent with the physician's instructions using the program output. The first drug true concentration can be entered into a programmer device as the only drug concentration entered. Another program calculates a consistent first drug, second drug, and diluent amount to be added to a mixture for injection into a fixed flow rate, implantable drug delivery device. Methods preferably output true concentrations and dose rates for all drugs to be added and most preferably show all calculations used to arrive at the flow rate and mixture amount calculations. Yet another program receives a new desired drug dose rate for a previously filled device. The program accepts the existing mixture volume and true drug concentrations for a partially depleted device and calculates a new mixture flow rate to achieve the desired dose rate using the existing mixture. The methods can be implemented as executable computer programs in programmer devices, general purpose computers, servers, handheld computers, and personal digital assistants.

Process for winding tyre surface and system thereof

The invention provides a tire tread winding method and a system thereof. The method comprises the steps as follows: a rubber sheet is extruded from an extruding machine, and then is cooled by a rubber-sheet cooling roll; a plastic film is stuck to the rubber sheet through a laminating mechanism at the same time; the film rubber-sheet is rolled up by a winding mechanism, and then is turned over or preserved; the film rubber-sheet roll is unreeled by adopting a center unreeling machine; then the plastic film and the rubber sheet are separated through a film and rubber-sheet detaching mechanism, and the plastic film is collected; the rubber sheet is delivered to a twister for tread winding. The system thereof comprises a first working-procedure device and a second working-procedure device; according to the production and the transportation direction of the rubber sheet, the first working-procedure device comprises the extruding machine, the rubber-sheet cooling roll as well as the laminating mechanism, and the winding mechanism in accordance with the installation positions; the second working-procedure device comprises the center unreeling machine, the film and rubber-sheet detaching mechanism, and the tread twister in accordance with the installation positions. The tire tread winding method and the system thereof increase the utility ratio of the extruding machine, the quality of the rubber sheet, and the winding quality.

Quality tracing system and method of expansion valves

The invention discloses a quality tracing system and method of expansion valves. The quality tracing system of the expansion valves comprises five hosts, wherein the hosts and working procedure devices are mutually connected, each host stores a production line Excel configuration table for each production line of the expansion valves, the production line Excel configuration tables of the hosts are the same, each production line Excel configuration table comprises working procedure parameter information including chain working procedure numbers in a built-in mode, and continuous numbering is carried out on the chain working procedure numbers according to the sequence of production line working procedures. Quality tracing of each expansion valve is achieved through a product and employee serial number, a production line number, a station number and each production line Excel configuration table. The quality tracing method of the expansion valves is characterized in that a working procedure chain is achieved, the working procedures and stations are traced, the production status of each employee is traced, and working procedure information is called to carry out judgment of quality. According to the quality tracing system and method of the expansion valves, due to the characteristics of different expansion valves, working procedure configuration is carried out through the production line Excel configuration tables, the characteristic that the production working procedures are related in a previous-and-next mode is taken into consideration, error control of production is achieved through the working procedure chain, and quality tracing is achieved through bar codes and radio frequency identification.
