  • Patent number: 6761703
    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tip to allow the tip to return to the initial 0.12-inch accommodating profile when the larger 0.14-inch guidewire is withdrawn from the catheter.

  • Patent number: 6733520
    Abstract: The present invention is a stent delivery system including a catheter, wherein the catheter includes an inflatable region. An expandable stent is disposed about at least a portion of the inflatable region. A first end of the at least one stent retaining sleeve covers an end of the stent prior to the stent being expanded for delivery. A second end of the at least one sleeve is engaged to at least a portion of the catheter adjacent to the inflatable region. The at least one stent retaining sleeve is constructed and arranged to longitudinally foreshorten from a first predetermined length to a second predetermined length when the stent is expanded for delivery. The second predetermined length being more than 5 percent shorter than the first predetermined length. When the stent is expanded for delivery, the at least one stent retaining sleeve is retracted off of the stent thereby releasing the stent from the catheter.

  • Patent number: 6613979
    Abstract: A device and method wherein electrical components are mechanically suspended and electrically interconnected in an insulative elastomeric body, such as silicone, thereby eliminating the need for a circuit board or other circuit substrate. The device can change shape through compression, distension, flexure, and other external forces while maintaining its electrical performance and mechanical integrity. The device can be compressed and deformed to fit snugly within another device, such as the shell of an electrical connector or a plastic clamshell, simultaneously creating spring forces for reliable electrical contacts and an environmental seal. Accordingly, the device and method can be used for a wide variety of purposes such as electrical filtering for avionics, computer or automotive connectors, or a non-intrusive manner to package electronics for medical implants.

  • Patent number: 6328710
    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.

  • Patent number: 5590058
    Abstract: A device for monitoring the environment of a battery. The device takes the form of a generally flat wafer-like substrate having openings therein for receiving the posts of the battery. The device is arranged so that it is sandwiched between the battery and its connector when the female receptacles of the connector are mated with the posts. Circuitry on the wafer contains a memory for recording information about the battery characteristics. This information can be read from the memory to provide knowledge about battery operating time, number of charge/discharge cycles, number and severity of deep-discharge cycles, total time spent in deep discharge, temperature fluctuations and G-loads applied to the battery. By taking advantage of the existing space between mated battery connectors, no additional mounting hardware or battery modifications are required.
