Endovascular graft with sensors design and attachment methods
View Patent ↗A endovascular graft having sensing devices attached thereto to facilitate measurement of pertinent parameters within the vasculature into which the graft is implanted. Power sources and transmitters may be attached to the graft to facilitate transmission of measurements to a receiving device outside the patient's body. The sensing devices, may be electrically passive or integrated devices with measurement and transmission capability. The sensing devices may be attached to specific locations on the graft material or attached to the lumen, thereby providing pertinent parameters from critical points inside the vasculature, or may be dispersed over the surface of the graft material or within the lumen to provide a profile of pertinent parameters. The sensing devices may be attached to the graft material with one suture using a running stitch to minimize graft bulk and may be coated with a material to inhibit or control tissue growth.
1. An endoluminal prosthesis for repairing vasculature, comprising:
an endovascular graft having one or more sensing devices attached thereto, each sensing device configured to provide information regarding a pertinent parameter inside the vasculature; and
at least one receiving device located outside a patient's body, each receiving device configured to receive the information provided by one or more sensing devices;
wherein each sensing device is attached to the endovascular graft by one continuous suture forming a running stitch engaging the sensing device and starting from one location along the sensing device, around the sensing device, and back;
wherein each sensing device comprises suture loops.
2. The prosthesis of claim 1 , wherein the ends of the suture are connected together external the endovascular graft by a single knot.
3. The prosthesis of claim 1 , wherein each sensing device comprises suture holes.
