Abstract: A medical device for permanent implantation in a circulatory system of a patient may include an implant configured for percutaneous or minimally-invasive insertion into the patient, at least one connector fixedly attached to the implant and configured to releasably attach to a delivery device, the at least one connector being exposed to blood flow within the circulatory system following implantation, and an anti-thrombus feature configured to transition from an undeployed state to a deployed state.

Abstract: A guidewire system may include a tubular guidewire including at least one lumen and a plurality of apertures disposed through an outer wall, and at least one pressure wire slidably disposed within the at least one lumen, the at least one pressure wire having at least one pressure sensor disposed thereon. A method of measuring a blood pressure gradient across a treatment site may include advancing the tubular guidewire to the treatment site, positioning at least one aperture distal and at least one aperture proximal of the treatment site, translating the pressure wire within the tubular guidewire, positioning the pressure wire such that a distal pressure sensor is disposed adjacent the at least one aperture distal of the treatment site, and a proximal pressure sensor is disposed adjacent the at least one aperture proximal of the treatment site, and measuring a blood pressure gradient across the treatment site.
