Abstract
A delivery system for an intracorporeal device includes a sheath defining one or more lumens shaped to receive a delivery catheter or shaft and a guidewire. The system may include a delivery shaft having a distal coupling feature adapted to releasably couple with a proximal coupling feature of the intracorporeal device. The delivery system may further include a hub through which the delivery shaft and guidewire are passed. The delivery shaft may be coupled to a feature, such as a knob, that enables manipulation of the delivery shaft to decouple the distal fixation feature from the proximal fixation feature of the intracorporeal device in order to deploy the intracorporeal device within a patient.
Claims20
A delivery system, comprising
- an intracorporeal device comprising a proximal coupling feature and a device body, wherein the intracorporeal device is a pressure sensor configured to be located and fixed at a deployment site in a vessel;
- a delivery catheter comprising a distal coupling feature configured to be coupled to the proximal coupling feature;
- a sheath adapted to receive the delivery catheter;
- a first lumen provided in the sheath and configured to receive the delivery catheter;
- and
- a second lumen provided in at least one of the sheath or delivery catheter.
A method for delivering an intracorporeal device, comprising:
- advancing a sheath along vasculature to a deployment site;
- providing the intracorporeal device comprising a proximal coupling feature and a device body, wherein the intracorporeal device is a pressure sensor;
- coupling a distal coupling feature of a delivery catheter to the proximal coupling feature of the intracorporeal device;
- the sheath including a first lumen having a proximal end and a distal end, the first lumen configured to receive the delivery catheter;
- providing a second lumen in at least one of the sheath or delivery catheter;
- translating the delivery catheter within the first lumen such that the intracorporeal device and the distal end of the delivery catheter are proximate to the deployment site;
- and
- decoupling the distal coupling feature of the delivery catheter from the proximal coupling feature of the intracorporeal device.
