163 results about "Measured blood pressure" patented technology

Blood pressure is measured in millimeters of mercury (mm Hg) and recorded with the systolic number first, followed by the diastolic number. For example, a normal blood pressure would be recorded as something under 120/80 mm Hg.

Implantable medical device for monitoring cardiac blood pressure and chamber dimension

InactiveUS20050027323A1Maximize cardiac outputConvenient timeCatheterHeart stimulatorsSonificationHeart chamber
Implantable medical devices (IMDs) for monitoring signs of acute or chronic cardiac heart failure by measuring cardiac blood pressure and mechanical dimensions of the heart and providing multi-chamber pacing optimized as a function of measured blood pressure and dimensions are disclosed. The dimension sensor or sensors comprise at least a first sonomicrometer piezoelectric crystal mounted to a first lead body implanted into or in relation to one heart chamber that operates as an ultrasound transmitter when a drive signal is applied to it and at least one second sonomicrometer crystal mounted to a second lead body implanted into or in relation to a second heart chamber that operates as an ultrasound receiver. The ultrasound receiver converts impinging ultrasound energy transmitted from the ultrasound transmitter through blood and heart tissue into an electrical signal. The time delay between the generation of the transmitted ultrasound signal and the reception of the ultrasound wave varies as a function of distance between the ultrasound transmitter and receiver which in turn varies with contraction and expansion of a heart chamber between the first and second sonomicrometer crystals. One or more additional sonomicrometer piezoelectric crystal can be mounted to additional lead bodies such that the distances between the three or more sonomicrometer crystals can be determined. In each case, the sonomicrometer crystals are distributed about a heart chamber such that the distance between the separated ultrasound transmitter and receiver crystal pairs changes with contraction and relaxation of the heart chamber walls.

Blood pressure monitoring apparatus

A blood pressure monitoring apparatus which continuously estimates and monitors the blood pressure by using the pulse wave propagation time can accurately estimate the blood pressure. While an estimated blood pressure is continuously calculated by using the pulse wave propagation time, the correlation between the pulse wave propagation time and the interval between feature points contained in two consecutive heart beat waveforms of an electrocardiogram is monitored. If the correlation is reversed, the blood pressure is actually measured, and the estimated blood pressure is corrected on the basis of the difference between the estimated blood pressure and actually measured blood pressure.

Technique to confirm correct positioning of arterial wall sealing device

Methods and systems related to sealing punctures in blood vessels (such as following an angio or PTCA procedure) are disclosed. The position of a distal end of an introducer assembly in tissue is determined using a pressure sensor. The pressure sensor is connected to the proximal end of the introducer assembly. The introducer assembly has a fluid path between its distal end and its proximal end. Measured blood pressure is outputted as an indication of the position of the distal end of the introducer assembly in the tissue. Proper positioning of a seal is confirmed by placing the introducer assembly such that its distal end is in tissue outside a puncture in a blood vessel wall and observing a characteristic of blood at the proximal end of the introducer assembly. In both techniques, a waveform of the blood pressure at the distal end of the introducer assembly may be displayed on a display to provide additional information to a surgeon as to the relative position of the components with respect to various tissues.
