An implantable vital sign sensor including a housing including a first portion, the first portion defining a first open end, a second open end opposite the first end, and a lumen there through, the first portion being sized to be implanted substantially entirely within the blood vessel wall of the patient. A sensor module configured to measure a blood vessel blood pressure waveform is included, the sensor module having a proximal portion and a distal portion, the distal portion being insertable within the lumen and the proximal portion extending outward from the first open end.

Aspects of the disclosure relate to pledget stimulation/recording electrode assemblies that are particularly useful for automatic periodic stimulation. Embodiments are compatible with nerve monitoring systems to provide continuous stimulation of a nerve during surgery. Disclosed embodiments include an electrode assembly having one or more electrodes rotatably supported by and positioned within a pledget substrate. The flexible pledget substrate conforms and fixates to bioelectric tissue to secure the electrode assembly in position, wrapped around the target tissue. In some embodiments, the pledget substrate includes two bodies, each including at least one electrode, the two bodies being selectively separable so that the bodies can be repositioned with respect to one another. The electrode assembly further includes a lead wire assembly including at least one insulating jacket positioned around a wire core. Optionally, the electrode assembly includes an insulating cup interconnecting the electrode and the insulating jacket.

A pessary system for providing pelvic floor support for USL and other ligaments. The pessary has an elongated probe with independently inflatable balloons each located substantially the same distance from the insertion end of the probe and which inflate into separate radial sectors. The probe can be inserted into a vaginal cavity and the balloons inflated provide mechanical support to the USLs. Independent inflation of each balloon allows the mechanical USL support provided to be varied on left and right sides to compensate for differences in the degree of degradation and positioning of the USL ligaments on either side.

A wearable device includes a wearable device main body, a sensor part configured to contact a skin surface of a user of the wearable device, and measure a bio-signal of the user, and a shock absorber that is interposed between the wearable device main body and the sensor part to mechanically connect the wearable device main body and the sensor part, and that is configured to reduce motion transmission between the wearable device main body and the sensor part to permit the wearable device main body to move independently from the sensor part.

An implantable medical device, such as a sensor for monitoring a selected internally detectable physiological parameter of a patient, is attached to a fixation assembly that is deployable within the patient to position and orient the sensor to enable it to perform its function. The fixation assembly is formed having at least one flexible asymmetric connector where each fixation member includes a plurality of loops, wherein a first loop of the plurality of loops has a maximum pitch that is different from a maximum pitch of a second loop of the plurality of loops. The attachment of the housing and the fixation assembly includes providing a tubular member that is welded to the housing and crimped over a section of the fixation assembly.

In one embodiment, the present disclosure relates to an implantable sensor system for sensing biological signal of a patient comprising: an anchor for coupling the sensor to at least one patient skull base structure; a first sensor coupled to the anchor for sensing, at a first location proximate to the at least one patient skull base structure, at least one biological signal of a patient; and a transmitter coupled to the sensor and capable of transmitting data from the sensor to an external device.

The present invention relates to an electrode array (1) for measuring the pH of animal tissues comprising an indicator electrode (2), and a reference electrode (3). The reference electrode (3) is all solid state and comprises a steel wire (3a) with an applied layer of conductive polymer (3b) and with a membrane (3c) containing ionic liquid and polyurethane. Furthermore, the present invention relates to a probe (11) for real-time continuous measurement of the pH of animal tissues comprising a body (12) in the form of a mounting capsule in which an electrode array (1) according to the present invention, a vacuum system (13), a temperature sensor (14) are housed. The vacuum system (13) is designed to attach the probe (11) to the tissue surface and comprises a vacuum tube (13a) and a vacuum surface (13b), wherein the temperature sensor (14) is a contact sensor designed to be applied to the surface of the tissue.

Provided is a pelvic floor stiffness measuring device including: based on a longitudinal direction, a pair of pressure members including insertion parts formed at each end thereof, grip parts formed at each other end of the pair of pressure members, and a hinge part that does not intersect between the insertion part and the grip part, the pair of insertion parts being open/closed by opening/closing the grip parts around the hinge part, in which the pair of insertion parts has each one end forming a pelvic floor pressure area based on the longitudinal direction and each other end connected to the hinge part, and has a downward convex curved surface based on a widthwise axis of symmetry through which the pair of pressure members is open/closed, and is connected by an intermediate area in which a point where the pair of insertion parts intersect is formed at least in part.

In one embodiment, the present disclosure relates to an implantable sensor system for sensing biological signal of a patient comprising: an anchor for coupling the sensor to at least one patient skull base structure; a first sensor coupled to the anchor for sensing, at a first location proximate to the at least one patient skull base structure, at least one biological signal of a patient; and a transmitter coupled to the sensor and capable of transmitting data from the sensor to an external device.
