Abstract:
A catheter is disclosed providing a balloon catheter having a distal tip that is flexible while additionally incorporating high column strength. The present invention additionally provides a distal tip region that accommodates for various sized guidewires. In preferred embodiments, the distal tip region is initially configured for accommodating the passage of 0.12-inch guidewires only. Through specific manufacturing processes, however, the distal tip is modified so that it also may be expanded to accommodate the passage of 0.14-inch guidewires. In additional preferred embodiments, an elastomeric sleeve is disposed over the modified distal tip to allow the tip to return to the initial 0.12 -inch accommodating profile when the larger 0.14-inch guidewire is withdrawn from the catheter.
Abstract:
The control device is used to control delivery of fluid from a fluid delivery system during a medical injection procedure. The fluid delivery system includes an injector adapted to actuate a syringe used to deliver the injection fluid to a patient. The control device is operatively associated with the injector for controlling discrete flow rates of injection fluid delivered to the patient. The control device includes a housing and an actuator associated with the housing. An electronic substrate is disposed within the housing and comprises a conductive pattern. The actuator is adapted for operative association with the conductive pattern. The conductive pattern includes a plurality of predetermined digital values corresponding to discrete flow rates of injection fluid to be delivered by the injector, such that when the actuator is actuated the actuator operatively associates with the conductive pattern for transmitting the digital values to the injector.

Abstract:
A method for forming a balloon for a dilatation catheter may utilize the steps of extruding a tubing preform of a polyester resin and then blowing the tubing into an oriented balloon, wherein the tubing preform is dried prior to blowing into the balloon form. Other process steps by which balloon cone and waist thicknesses may be reduced involve varying the axial tension and blowing pressure at several stages as a mold containing the balloon preform is dipped into a heating medium. Specifically, tubing of a thermoplastic material is placed in a mold and blown by pressurizing and tensioning the tubing and gradually dipping the mold into a heated heat transfer media so as to sequentially blow a first waist, a body and a second waist portion. The tubing is subjected to a relatively lower pressure while the body portion is blown than while the first and second waist portions are blown.
Abstract:
A surge suppression device which fits over the end of an electrical plug and permits normal mating of the plug with the female receptacle. In the preferred embodiment, the device includes a body of metal-oxide varistor (MOV) material where one pin is connected to one plate on the MOV and another plug pin is connected to an opposing plate on the MOV. The MOV breaks down when experiencing excessive voltage levels to shunt potentially damaging voltages between the plug pins thereby preventing the spikes from reaching the protected equipment.

Abstract:
A fluid path set for a fluid delivery system includes a tube coil that is designed to optimally position one or more volumes of a pharmaceutical within an ionization chamber to measure and prepare a pharmaceutical dose for administration to a patient. The fluid path set includes a medical fluid component having a first tubing section for connection to a source of a medical fluid, a pharmaceutical component having a second tubing section for connection to a source of a pharmaceutical, and a coil assembly which includes the tube coil. The tube coil may be maintained in a desired dimensional geometry by means of a core structure around which the tube coil is positioned.
Abstract:
A substantially tubular member comprises a body. The body is constructed from a first material and has an external surface. At least a portion of the external surface has a predetermined pattern of a second material deposited thereon. The predetermined pattern of the second material is deposited on the at least a portion of the external surface by one or more printing processes such as solution coating, spray coating, thermal printing, piezo jet printing, contact printing and any combination thereof.

Abstract:
A balloon catheter comprises an inner tube, a medical balloon and an inflation lumen. The medical balloon is disposed about the inner tube and in fluid communication with the inflation lumen. A collapsible portion of the inner tube is constructed to collapse inward upon delivery of an inflation fluid to the medical balloon to secure the inner tube to the guidewire.
