Apparatus and method for sensor deployment and fixation

An intracorporeal device delivery system comprising:

• a delivery shaft comprising a distal coupling feature;
• a sheath adapted to receive a guidewire and defining a delivery shaft lumen, the delivery shaft disposed within the delivery shaft lumen;
• and
• an intracorporeal device comprising a proximal coupling feature and a device body, the device body defining an axial envelope extending proximally from the device body;
• wherein the distal coupling feature is releasably coupled to the proximal coupling feature such that, when coupled, the distal coupling feature is disposed within the axial envelope defined by the device body;
• wherein the intracorporeal device comprises a guide defining a passage shaped to receive the guidewire, the passage disposed outside the axial envelope.

An intracorporeal device delivery system comprising:

• a delivery shaft comprising a distal coupling feature extending from a distal end of the delivery shaft, the distal coupling feature comprising a threaded extension;
• a sheath adapted to receive a guidewire and defining a delivery shaft lumen, the delivery shaft disposed within the delivery shaft lumen;
• and
• an intracorporeal device comprising a proximal coupling feature and a device body, the device body defining an axial envelope extending proximally from the device body and the proximal coupling feature comprising a threaded hole shaped to receive the threaded extension of the delivery shaft, wherein the intracorporeal device is a pressure sensor configured to be located and fixed in a vessel;
• wherein the distal coupling feature is releasably coupled to the proximal coupling feature such that, when coupled, the distal coupling feature is disposed within the axial envelope defined by the device body.

An intracorporeal device delivery system comprising:

• a sheath defining each of a delivery catheter lumen and a guidewire lumen separate from the delivery catheter lumen;
• a delivery catheter extending through at least a portion of the delivery catheter lumen;
• an intracorporeal device releasably coupled to a distal portion of the delivery catheter, wherein the intracorporeal device is a pressure sensor configured to be located and fixed in a vessel;
• and
• a hub coupled to a proximal end of the sheath and comprising a port, wherein a cross-sectional area of the delivery catheter lumen exceeds a cross-sectional area of the delivery catheter such that an annular volume is defined between the delivery catheter and an inner wall of the delivery catheter defining the delivery catheter lumen, the annular volume in communication with the port.
