Method for controlling flow in a bodily organ
There is provided a method for treating a male impotent patient comprising stimulating at least one portion of the patient's normal penile tissue or the prolongation thereof to at least restrict the blood flow leaving the penis to achieve erection. To improve the erection effect the method further comprises gently constricting the penile portion or the prolongation thereof to restrict the venous blood flow in the penile portion, and then stimulating the constricted penile portion to cause contraction of the penile portion to at least further restrict the blood flow leaving the penis to achieve erection.
ENHANCED IMPLANT-TO-IMPLANT COMMUNICATIONS
Implantable medical devices (IMDs), systems, and methods for use therewith are disclosed. One such method is for use by a leadless pacemaker (LP) configured to perform conductive communication with another implantable medical device (IMD). The method includes the LP storing information that specifies when, within a cardiac cycle, the LP and the other IMD implanted in a patient are likely oriented relative to one another such that conductive communication therebetween should be successful. The method also includes the LP sensing a signal indicative of cardiac activity of the patient over a plurality of cardiac cycles, and outputting one or more conductive communication pulses, during a portion of at least one of the cardiac cycles, wherein the portion of the at least one of the cardiac cycles is identified based on the signal that is sensed and the information that is stored.
Method for controlling flow in a bodily organ
A method for treating a male impotent patient, the method comprising the steps of cutting the skin of the patient, inserting a dissecting tool and dissecting an area of at least one portion of a tissue wall of a penile portion, and placing a medical device. The medical device comprises a constriction device configured to gently constrict the penile portion to restrict the blood flow leaving the penis, and a stimulation device configured to stimulate the penile portion constricted by the constriction device to at least further restrict the blood flow leaving the penis to achieve erection.
IMPLANTABLE MEDICAL DEVICE FOR VASCULAR DEPLOYMENT
A leadless cardiac pacemaker (LCP) may be deployed within a patient's vasculature at a location near the patient's heart in order to pace the patient's heart and/or to sense electrical activity within the patient's heart. In some cases, an LCP may be implanted within the patient's superior vena cava or inferior vena cava. The LCP may include an expandable anchoring mechanism configured to secure the LCP in place.
DETECTING, ASSESSING AND MANAGING A RISK OF DEATH IN EPILEPSY
A method for determining and responding in real-time to an increased risk of death relating to a patient with epilepsy is provided. The method includes receiving cardiac data and determining a cardiac index based upon the cardiac data. The method includes determining an increased risk of death associated with epilepsy if the indices are extreme, issuing a warning of the increased risk of death and logging information related to the increased risk of death. Also presented is a second method for determining and responding in real-time to an increased risk of death relating to a patient with epilepsy comprising receiving at least one of arousal data, responsiveness data or awareness data and determining an arousal index, a responsiveness index or an awareness index, where the indices are based on arousal data, responsiveness data or awareness data respectively. The second method includes determining an increased risk of death related to epilepsy if indices are extreme values, issuing a warning of the increased risk of death and logging information related to the increased risk of death. A computer readable program storage device is also provided. Also provided is a method for receiving body data, determining a cardiac, an arousal, a responsiveness, or a kinetic index, determining an increased or increasing risk of death over a first time window relating to a patient with epilepsy and issuing a warning and logging relevant information.
Method and apparatus for verifying bradycardia/asystole episodes via detection of under-sensed events
A system and method for detecting and verifying bradycardia/asystole episodes includes sensing an electrogram (EGM) signal. The EGM signal is compared to a primary threshold to sense events in the EGM signal, and at least one of a bradycardia or an asystole is detected based on the comparison. In response to detecting at least one of a bradycardia or an asystole, the EGM signal is compared to a secondary threshold to sense events under-sensed by the primary threshold. The validity of the bradycardia or the asystole is determined based on the detected under-sensed events.
Systems and methods to optimize anti-tachycardial pacing (ATP)
Apparatus, systems and methods are provided for prevention and/or remediation of cardiac arrhythmias, e.g. optimizing anti-tachycardia pacing (ATP) algorithms. More particularly, implantable devices are provided that measure and treat cardiac arrhythmias. By monitoring the ATP attempt from additional electrodes, far-field morphology analyses, and/or measuring the return interval from a failed ATP attempt; the devices may estimate when entrainment has occurred, the amount of delay within the reentrant tachycardia, and/or tachycardia termination/acceleration. These variables and occurrences can be used to optimize the first and/or subsequent ATP attempts. Furthermore, other exemplary embodiments describe methods to integrate electrical restitution properties into the design of ATP pacing algorithms to facilitate tachycardia termination.
Pacing crosstalk detection
An implantable pacemaker is configured to sense a cardiac electrical signal received by a pair of electrodes coupled to the pacemaker, start a pacing escape interval to control a time that a pacing pulse is delivered in a heart chamber, and detecting if the sensed cardiac electrical signal is a crosstalk event that is an electrical pulse delivered to the patient by a different device than the implantable pacemaker. The implantable pacemaker withholds restarting the pacing escape interval in response to sensing the cardiac electrical signal based on detecting the sensed cardiac electrical signal as the crosstalk event.
Patient Signal Analysis Based on Vector Analysis
Disclosed herein is a framework for facilitating patient signal analysis based on vector analysis. In accordance with one aspect, a set of vectors is generated from a patient signal data waveform. The vectors may be directed from a common center to points of interest on the patient signal data waveform. The framework may further extract one or more vector parameters from the set of vectors, and determine one or more vector ratios based on the vector parameters to monitor changes in the patient signal data waveform.
