Adaptive alarm system

An adaptive alarm system is responsive to a physiological parameter so as to generate an alarm threshold that adapts to baseline drift in the parameter and reduce false alarms without a corresponding increase in missed true alarms. The adaptive alarm system has a parameter derived from a physiological measurement system using a sensor in communication with a living being. A baseline processor calculates a parameter baseline from a parameter trend. Parameter limits specify an allowable range of the parameter. An adaptive threshold processor calculates an adaptive threshold from the parameter baseline and the parameter limits. An alarm generator is responsive to the parameter and the adaptive threshold so as to trigger an alarm indicative of the parameter crossing the adaptive threshold. The adaptive threshold is responsive to the parameter baseline so as to increase in value as the parameter baseline drifts to a higher parameter value and to decrease in value as the parameter baseline drifts to a lower parameter value.

Self-powered resonant leadless pacemaker

InactiveUS20070293904A1Increases natural velocity and acceleration of heart muscleExtended durationElectrotherapyCardiac cycleCardiac pacemaker electrode
A self-powered medical device, for example a pacemaker uses the variations of blood pressure inside the heart or a major artery to create a mechanical resonance in an electromagnetic or piezoelectric generator. The resonance extends the time power is generated during the cardiac cycle. The pressure variations compress a bellows carrying the resonant generator. The inside of the bellows may be evacuated to a partial or full vacuum, and a spring restores the bellows to the desired equilibrium point, acting against the blood pressure. The current pulses are stored in a capacitor. Eliminating the battery allows dramatic miniaturization of the medical device to the point it can be implanted at the point of desired stimulation via a catheter.

Catheters having selectively insertable or selectively activatable and releasable stiffening mechanisms are provided. In general, the catheter is inserted, navigated and withdrawn from a subject in a relaxed, flexible condition and stiffening mechanisms are deployed to prevent the catheter from shifting during placement or operation of an accessory device or tool through the catheter. Stiffening members(s) may be inserted into and removed from one or more longitudinal channel(s) provided in proximity to the catheter wall and generally coaxial with the primary catheter lumen to change the stiffness properties of the catheter. The properties, configuration and size of the stiffening members and channels may be varied to vary the stiffness properties of the catheter and stiffening members may be constructed from materials having shape change properties or materials that change conformation or stiffness with application of heat, current or electrical field. Stiffening mechanisms may also employ energy absorbing and viscoelastic polymer materials having variable stiffness properties depending on ambient conditions.

Subcutaneously implanted cannula and method for arterial access

A catheter with valve for implantation in a vascular structure of a living being. The catheter is in the general shape of a "T" with the top of the "T" implanted within the lumen of a vascular structure, and the leg of the "T" extending out of the vascular structure through an incision in the vascular structure. The lumen of the implanted portion of the catheter completely occupies the lumen of the vascular structure, causing all blood flow through the vascular structure to be directed through the implanted portion of the catheter. A valve is placed in the wall of the implanted portion of the catheter which opens into the lumen of the leg of the "T" of the catheter upon application of sufficient differential pressure between the lumens of the two portions of the catheter. The leg of the "T" is connected to the side wall of the implant portion of the catheter at an angle, such that the axis of the lumen of the leg of the "T" intersects the axis of the lumen of the implanted portion of the catheter at approximately a 45 degree angle.
