A connector (140) is provided with a holding component (141), a support component (148), a terminal (144) electrically connected to a contact of a guide wire (130) held by the holding component (141), and a guide component (147) rotatable around an axial line (130A) of the guide wire (130) with respect to the support component (148). The holding component (141) is provided with a body (150) having an insertion hole (150a) for the guide wire (130) and a holding piece (151) extending along an axial line of the insertion hole (150a) from the body (150) and capable of being elastically deformed inward in a radial direction with respect to the axial line. The guide component (147) has a guide surface (165a) guiding the holding piece (151) inward in the radial direction. The holding component (141) is slid along the axis line of the insertion hole (150a) with respect to the guide component (147), whereby the holding piece abuts on the guide surface (165a) to be elastically deformed inward in the radial direction.

An intravascular sensor device can be used to guide treatment of a diseased blood vessel in the body of a patient. In some examples, the intravascular sensor device includes a pressure sensor and an ultrasound transducer. The intravascular sensor device is used to measure a pressure within the diseased blood vessel and acquire an ultrasound image of the diseased blood vessel. The pressure may be measured during hyperemic blood flow that is caused by a pharmacologic vasodilator drug. The measured pressure can be used to calculate a fractional flow reserve value. The ultrasound image can be used to determine a physical dimension of the blood vessel, such as cross-sectional area. The fractional flow reserve value and physical dimensions of the blood vessel can be used to optimize patient treatment.

In the present invention, a system and associated method is provided for monitoring vital parameters of a patient. The monitoring system includes sensors disposed on the patient and operably connected to a monitor. The parameters that are sensed by the sensors are transmitted to the monitor and compared with alarm thresholds and operational criteria stored within the monitor. When an alarm condition is sensed by the system, the system can actively solicit patient assistance in the confirmation of the alarm condition based on a set of reactive inputs stored within the system to enable medical personnel to appropriately respond to clinically relevant sensed alarm condition(s).

In the present invention, a system and associated method is provided for monitoring vital parameters of a patient. The monitoring system includes sensors disposed on the patient and operably connected to a monitor. The parameters that are sensed by the sensors are transmitted to the monitor and compared with alarm thresholds stored within the monitor. The alarm thresholds stored within the monitor are modified by inputs supplied to the monitor regarding the particular condition(s) of the patient being monitored to provide more accurate alarm determinations for the patient. The dynamic adjustment of the alarm threshold during monitoring can be based on a set of proactive inputs to prevent and/or limit the occurrence of unnecessary or clinically irrelevant alarm conditions or a set of reactive inputs that follow immediately after an alarm event is detected, to enable medical personnel to appropriately respond to sensed alarm condition(s).

Embodiments of the present disclosure relate to systems and methods for determining a subject's blood pressure using one or more implantable medical devices (IMDs). In an embodiment, a medical system comprises: at least one implantable medical device configured to sense signals associated with heart sounds of a subject and a processing unit communicatively coupled to the at least one implantable medical device. The processing unit is configured to: receive heart sound signals corresponding to the signals associated with the heart sounds; and calculate a surrogate of the subject's blood pressure using at least one heart sound signal of the received heart sound signals.

A pressure sensor system with at least two absolute pressure sensors can have an external sensor with a pressure sensitive surface in contact with atmospheric pressure (proximal) and internal sensors each with a pressure sensitive surface in contact with one or more regions at an unknown pressure (distal). The unknown pressure is determined by a means to calculate the difference between the first sensor and the internal sensors.

Systems and methods are provided for optimizing hemodynamics within a patient's heart, e.g., to improve the patient's exercise capacity. In one embodiment, a system is configured to be implanted in a patient's body to monitor and/or treat the patient that includes at least one sensor configured to provide sensor data that corresponds to a blood pressure within or near the patient's heart; at least one component designed to cause dyssynchrony of the right ventricle, and a controller configured for adjusting the function of the at least one component based at least in part on sensor data from the at least one sensor.
