Patent number: 5855975Abstract: A resinous film at least partially formulated from a recycled resin and containing a vapor phase corrosion inhibitor. One embodiment of the invention is a single layer film which is formulated from three components. The first component is a recycled resin such as polyethylene, the second component is a fresh resin identical to the first, and the third component is a vapor phase anti-corrosion agent. Multi-layer films are also included. The films emit the anti-corrosion agent over a period of time to thereby protect items encased by the film.Type: GrantFiled: June 16, 1995Date of Patent: January 5, 1999Assignee: Cortec CorporationInventors: Boris A.

Patent number: 5855594Abstract: A cardiac pacing and sensing system includes a body implantable unit for generating tissue stimulation pulses and manipulating information based on sensed signals, and a catheter for transmitting pulses from the unit to a pacing electrode adjacent myocardial tissue. The unit incorporates circuitry for generating response values, one associated with each stimulation pulse, based on a predetermined characteristic or parameter of the signals evoked by the pulses. To evaluate the efficacy of the parameter in distinguishing capture versus non-capture, the stimulation pulses are generated according to a protocol of high energy pulses guaranteed to effect capture interspersed with low energy pulses guaranteed not to effect capture. Data, accumulated and sorted into separate "capture" and "non-capture" sets, provides respective capture and non-capture composite values.Type: GrantFiled: August 8, 1997Date of Patent: January 5, 1999Assignee: Cardiac Pacemakers, Inc.Inventors: Arthur L. Olive, Brian D. Pederson, Veerichetty A. Kadhiresan, Donald L. Villalta

Patent number: 5855559Abstract: An instrument for achieving rapid hemostasis at the conclusion of a catheterization procedure comprising a hemostatic agent injection device for use with a conventional introducer sheath used to gain access to the blood vessel. The injection device includes an elongated tubular member having ejection ports proximate its distal end. A hub member is located on the proximal end of the tubular member and includes an elongated groove or track located in its surface with a transparent cover. The enclosed track is in fluid communication with the lumen extending through the tubular member. After the catheterization procedure, the instrument is inserted into the introducer sheath. Blood flows into the lumen of the device and into the enclosed track. The leading edge of the blood pulsates within the enclosed track, clearly indicating that the ports are located in the blood vessel and subjected to variations in blood pressure.Type: GrantFiled: February 14, 1997Date of Patent: January 5, 1999Assignee: Tricardia, Inc.Inventors: Robert A.

Patent number: 5852244Abstract: A non-contaminating pressure transducer module having an isolation member is disclosed. The isolation member isolates a pressure sensor within the transducer module from exposure to fluids flowing through a conduit in the module. The transducer module may be positioned in-line within a fluid flow circuit carrying corrosive materials, wherein the pressure transducer module produces a control signal proportional to either a gauge pressure or an absolute pressure of the fluid flow circuit. The pressure transducer module of the present invention also avoids the introduction of particulate, unwanted ions, or vapors into the flow circuit.Type: GrantFiled: December 1, 1997Date of Patent: December 22, 1998Assignee: NT International, Inc.Inventors: Diane L.

-
Patent number: 5843136Abstract: A method and apparatus for attenuating polarization voltages or "afterpotentials" which develop at the heart tissue/electrode interface following the delivery of a pacing stimulus to the heart tissue such that the evoked response of the heart may be accurately detected to determine whether each pacing stimulus resulted in heart capture or contraction, thereby facilitating improved tracking of the capture threshold for minimizing power consumption while assuring therapeutic efficacy. The conventional large capacitance coupling capacitor used to suppress DC components of the pacing spike has a second, much lower capacitance capacitor connector in series with it, the second capacitor being shunted by a switch so that its value can be selectively inserted in series with the coupling capacitor to effectively lower the overall capacitance of the coupling capacitor following delivery of the pacing spike.Type: GrantFiled: November 24, 1997Date of Patent: December 1, 1998Assignee: Cardiac Pacemakers, Inc.Inventors: Qingsheng Zhu, Julio C.
