20090275894 | TRANSVENOUS SOAKER CATHETER - A system and method for infusing a fluid medicament requires an indwelling catheter having an infusion member affixed to its distal end. A source of the fluid medicament is connected in fluid communication with the catheter's proximal end. In use, the catheter is positioned in the venous system of a patient with the infusion member embedded and stabilized in a volume of tissue. A pump is then activated to infuse fluid medicament from the source into extracellular fluid in the volume of tissue, at a predetermined fluid flow rate and for a predetermined time duration. | 11-05-2009 |
20100042185 | SYSTEM AND METHOD FOR TRANSVASCULAR ACTIVATION OF CARDIAC NERVES TO IMPROVE HEART FUNCTION - A system and method for electrically stimulating the heart muscle to improve heart function requires identifying a site in the venous system adjacent a sympathetic nerve. An electrode is then positioned at the site to electrically stimulate the nerve. In turn, this stimulation releases norepinephrine from the nerve to improve heart muscle contraction. | 02-18-2010 |
20100127874 | INFORMATION LOCATOR - A system and method for interrogating a plurality of different environments to locate an object within the environments includes a plurality of transceivers. A control unit is also provided to selectively operate each transceiver while it is positioned in a respective environment. For operation of the system, an identification tag is affixed to the object, and transmission of an interrogation signal from a selected transceiver is accomplished at an inaudible high frequency. The tag is then responsive to the interrogation signal to send a return signal back to the control unit via the transceiver. A follow-up search of the environment can be made with a hand-held mobile locator that electronically interacts with the tag to provide for a more precise location of the object in the environment. | 05-27-2010 |
20110301666 | System and Method for Transvascular Activation of Cardiac Nerves with Automatic Restart - A system and method for electrically stimulating the heart muscle to improve heart function requires identifying a site in the venous system adjacent a sympathetic nerve. An electrode is then positioned at the site to electrically stimulate the nerve. In turn, this stimulation releases norepinephrine from the nerve to improve heart muscle contraction. | 12-08-2011 |
20120022891 | Information Interface System - A system and method for controlling informational data of a patient includes an electronic database for archiving the informational data; a tag for identifying the patient; and an electronic device for linking the database and the ID tag with the linking device. In operation, the linking device uses identification data from the ID tag, and pre-programmed, security log-in data to establish access into the database. With this authorized access, selected data from the database can then be retrieved and used during the conduct of a patient visit protocol. After the patient visit has been completed, the database can be updated with any additional information obtained during the patient visit. | 01-26-2012 |
20120101476 | Transvenous Soaker Catheter Using Microfibers - A catheter tip for an infusion catheter has a hollow tubular shaped base member with a pair of annular shaped inflation balloons positioned in parallel on the base member. A plurality of microfibers are mounted on the cylindrical surface section between the balloons. The microfibers are in fluid communication with the lumen of the catheter tip. In operation, the catheter tip is advanced into the vasculature of a patient and to a site in a small vein that is near the target tissue for infusion. The balloons are then inflated to anchor the catheter tip, and fluid medicament is infused through the microfibers. In an alternate embodiment, the microfibers can be replaced with at least one orifice. | 04-26-2012 |
20130296671 | Method for Using a Pulse Oximetry Signal to Monitor Blood Pressure - A system for continuously monitoring the blood pressure of a patient over an extended time interval requires using a blood pressure measuring unit (e.g. a sphygmomanometer) to calibrate an oximeter. Specifically, the oximeter is used to continuously detect and measure amplitudes for each blood flow pulse of the patient. Periodically, the sphygmomanometer is used to measure blood pressures (systolic and diastolic) in an artery of the patient. Immediately after the measurement cycle is completed, a computer correlates the measured systolic pressure with the pulse amplitude that is detected by the oximeter. Thereafter, the pulse amplitudes that are detected by the oximeter are used as indications of variations in the systolic pressure during the extended time interval that follows. | 11-07-2013 |
20130310887 | Extracorporeal Unit for Inspecting the Insulation of an Electrical Wire of an Implanted Medical Device - A system is provided for testing the electrical integrity of an implanted pacemaker or defibrillator lead. The system includes a container holding an electrically conductive solution, such as a saline solution. A voltage source and two electrodes are provided to pass an electrical current through the solution. To use the system, the proximal end of the electrical lead is disconnected from the implanted electronic device, passed through the saline solution and then electrically connected to a device/monitor. During testing, the device/monitor sends a test pulse through the lead and monitors electrical activity in the lead. To test sequential locations along the length of the proximal segment, the segment is drawn through the saline solution and between the electrodes while test pulses are sent and monitored. The monitor detects abnormal electrical activity in the lead indicative of a break in lead insulation. | 11-21-2013 |
20150051463 | Oximetry Signal, Pulse-Pressure Correlator - A system and method are provided for using an oximeter to take blood pressure readings for an extended period of time. Calibration of the oximeter for this purpose requires use of a sphygmomanometer to determine a sequence of blood pressure readings taken for a patient over a sphygmomanometer duty cycle. During the duty cycle, readings for both blood pressure (sphygmomanometer) and blood flow amplitude (oximeter) are taken simultaneously at predetermined time intervals (e.g. patient pulse rate). These readings then determine an operational ratio between the two that can be used to translate pulse magnitude readings of the oximeter for presentation as blood pressure readings. Operationally, variations from the patient's systolic pressure can then be continuously monitored in real time. | 02-19-2015 |
