  • Patent number: 9005131
    Abstract: Disclosed is a system and method for monitoring the breath chemistry of a patient's breath using a specially designed self-condensing sensor module mounted in a mask, nasal cannula, headband with boom apparatus, or similar device for directing the patients' breath towards the self-condensing sensor. Monitoring of a patient's breath pH provided by the miniaturized self-condensing pH sensor provides for real-time monitoring of patient airway pH values. The specially designed self-condensing sensor module incorporates a data transfer means, e.g. direct wiring or by providing a transmitter with an antenna for wireless transferring of the pH data to a processing receiver. The self-condensing pH sensor comprises a multi-tubular design with the outer tubular member housing a silver chloride reference element, an ion conducting path, and an antimony sensor plug isolated in an inner tubular member that is co-linearly or coaxially configured with the outer tubular member.

  • Patent number: 7297120
    Abstract: Disclosed is a system and method for monitoring, diagnosing, and treating certain medical conditions, such as asthma, gastroesophageal reflux or laryngopharyngeal reflux. The system includes a mask apparatus or sensor module fitted with a pH sensor and thermocouple, a continuous positive airway pressure (CPAP) device, a processing receiver, and a therapeutic nebulizer/atomizer/humidifier device. The mask apparatus, CPAP device and therapeutic nebulizer/atomizer/humidifier device are connected by a pneumatic means. The pH sensor and the thermocouple are in electrical communication with the processing receiver that controls, through an electronic means, the CPAP device and therapeutic nebulizer/atomizer/humidifier device. The electrical communications can be in the form of a plurality of wires or employ wireless means.

  • Patent number: 6696121
    Abstract: A method for forming a balloon for a dilation catheter is provided herein. The method includes the steps of: (i) positioning a tube in a preconditioned mold; (ii) expanding the tube in a preconditioned mold to form a parison; (iii) positioning the parison in a balloon mold; and (iv) expanding the parison within the balloon mold to form the balloon. Thus, the tube is initially expanded into a parison in the preconditioned mold. Subsequently, the parison is expanded into a balloon in the balloon mold. Because of this unique manufacturing process, polyester block copolymers can be formed into balloons. Some of these polyester block copolymers could not be formed into a balloon using prior art blow molding processes. The resulting balloon exhibits superior characteristics, including relatively thin and consistent walls, soft texture, low uninflated crossing profile, expansion in a predictable fashion, and good tensile strength.

  • Patent number: 5876419
    Abstract: The present invention is a stent for insertion into an artery or other vessel. The stent is formed from a series of tubular shaped bands each formed with a first end which overlaps a second end. The overlap between the first and second ends is variable and allows each band to move between a contracted configuration and a fully expanded configuration which are within the elastic limits of the band. Each band includes a plurality of receivers and a first tab on a first edge of the band to secure each band at or near the fully expanded configuration and allow the stent to conform to the contours of the vessel. The bands are distributed along a substantially common axis to form a tube interconnected by a pair of elongated strips. In use, the stent is placed over a balloon catheter and compressed to adopt the contracted configuration. The stent may be maintained in the contracted configuration by a retainer.

  • Patent number: 5645789
    Abstract: A semi-compliant PET balloon and a method for manufacturing the balloon are disclosed. The method for manufacturing the semi-compliant PET balloon includes the steps of varying the temperature and inflation pressure on a tube of PET material in an ordered sequence to i) form the balloon, ii) thin the walls of the balloon, ii) size the balloon and then, iv) crystallize the PET material of the balloon. First, to form the balloon, the tube of PET material is preheated, and simultaneously pressurized and stretched. The pressure in the tube is then increased to conform the balloon to the shape of a mold. Next the balloon walls are thinned by decreasing pressure and providing additional stretch on the PET tube. A subsequent increase in pressure sizes the balloon. The sized balloon is next subjected to an increase in temperature and a decrease in pressure to crystallize the PET material. A cooling step completes the method for manufacture.

  • Patent number: 5643314
    Abstract: The present invention provides a self-expanding stent for insertion into an artery or other internal vessel. The stent is formed from a series of radial bands each formed with overlapping first and second ends. The overlap between the first and second ends is variable, allowing each band to move between a contracted configuration and an expanded configuration. The first and second ends of each band are both formed to include a tab which is folded to hold the first and second end against the band. The bands are distributed along a common axis to form a cylinder and interconnected by a pair of elongated strips. In use, the stent is placed over a balloon catheter and compressed to adopt the contracted configuration. The balloon catheter and stent are then advanced through a placement catheter and to a target site where the balloon is partially inflated to free the stent for self-expansion. The balloon may then be more fully inflated to further expand any of the radial bands in the stent.

  • Patent number: 5267958
    Abstract: A balloon catheter is disclosed having a catheter body and one or more loops external to the body and spaced from the balloon for insertion of a guidewire. A peelable sheath with a guidewiare lumen can instead be mounted exterior to the catheter body for holding the guidewire. The catheter body may optionally be reinforced with a stylet.
