A stent delivery system that obtains biological-related information or stent state information in a stent using a signal from a sensor after the stent indwells in a living body and then removing the sensor from the living body. A stent delivery system includes a sheath in which a stent is accommodated, a stent extrusion member, and a sensor device. The sensor device includes a sensor unit and a pressing portion configured to bring the sensor unit into contact with an inner surface of the stent indwelling into the living body. The sensor device can move the sensor unit in a rear end direction of the stent by movement of the stent extrusion member toward a rear end side or withdrawal of the sensor device. The sensor device can be taken out from the living body by removing the stent delivery system or the sensor device from the living body.

Devices, methods and systems for transmitting signals through a device located in a blood vessel of an animal, for stimulating and/or sensing activity of media proximal to the device, wherein the media includes tissue and/or fluid.

Methods for sensing or stimulating electrical activity of brain tissue from within an animal vessel by placement of an intravascular device within an animal vessel to control an external device, the intravascular device being adapted to at least one of sense and stimulate activity of brain tissue located outside the vessel proximate the intravascular device.

A control method, computer readable medium, and imaging apparatus for diagnosis being configured to create a tomographic image are disclosed. The method includes obtaining ultrasound line data oriented in a radial direction from a rotation center based on a signal obtained by executing the scanning; obtaining optical interference line data oriented in a radial direction from the rotation center based on a signal obtained by executing the scanning; identifying a line or a group of lines having a same feature out of each line data of the ultrasound tomographic image and the optical tomographic image; determining segmentation positions for a bundle of lines corresponding to at least a single frame included in each tomographic image from each line data of the ultrasound tomographic image and the optical tomographic image with respect to the identified line or group of lines; and creating a tomographic image from the determined bundle of lines.

A prosthesis for monitoring a characteristic of flow includes a first tubular prosthesis having a lumen and a sensor for detecting the characteristic of flow through the lumen. The sensor may be covered with another tubular prosthesis or by a layer of material in order to insulate the sensor from the fluid flow. A pocket may be formed between the tubular prosthesis and the adjacent layer of material or prosthesis and the sensor may be disposed in the pocket.

Minimally invasive systems, and tools provided herein in novel enhanced and modified form for this application used has Used deep brain knowledge and structural data to generate novel enhanced intracranial signals to develop, characterize and ameliorate challenges and disease states with application specific tools modified from tradition EEG for Epilepsy to address a myriad of conditions in patients, without any need for invasive protocols traditionally employed. Also disclosed is a novel enhanced system that can be permanently implanted (like a pacemaker) that can both sense epileptiform activity, as well as apply a current to the seizure focus and arrest seizure progression.

A method of assembling an electronic prosthetic aortic valve is provided. The method includes inserting an electronics component into a valve component, the electronics component including one or more electrodes and a prosthetic-valve coil, and the valve component including a frame and prosthetic leaflets coupled to the frame; and coupling the electronics component to the valve component. Other embodiments are also described.

Prosthetic heart devices may be implanted into the heart with a sensor coupled to the device, the sensor being configured to measure physiological data, such as blood pressure, in the heart. Devices that may employ such sensors include prosthetic heart valves and occlusion devices, although sensor systems may be deployed in the heart separate from other implantable devices. The sensors may include a body with different configurations for attaching to the implantable device, such as apertures for sutures or fingers for connecting to structures of the implantable device. The sensors may provide data that allow a determination of aortic regurgitation or other information indicative of function of the implantable device and patient health during and after implantation of the device.
