An implantable transvascular pressure sensing device may include at least one deflection sensor configured to output a deflection signal indicative of vascular wall deflections. A implantable transvascular pressure sensing device may further include an implantable sensor support member attached to the deflection sensor, the sensor support member configured to facilitate contact between the deflection sensor and a first vessel wall at a portion of a first vessel proximate a second vessel, wherein the portion of the first vessel wall is adjacent to the second vessel such that wall deflections of the second vessel deflect the portion of the first vessel wall. A method of measuring a parameter of a vessel can include generating a deflection signal from a sensor within a vein, the deflection signal indicative of venous wall deflections of the vein, and determining a parameter value associated with a vessel contacting the vein using the deflection signal.
