  • Patent number: 12310769
    Abstract: The invention provides a method and system for performing angiography and angioplasty within lumen of a blood vessel. To perform angiography, a soft angiography balloon is glided over an angiography guide wire up to a target site through the support of a guide catheter. Subsequently, the soft angiography balloon is inflated at very low pressure 1-2 atmospheres atraumatically, using one or more inflation mechanisms to record one or more angiographic pictures of an internal shape of the lumen. Next, an angioplasty with or without metallic stent or BVS is performed at the target site, and luminal gain is confirmed by repeating soft balloon angiography by re-inflating the soft angiography balloon in a way similar to IVUS or but superior to OCT for metallic stent. Further, a nephrotoxic contrast agent is fully withdrawn from the balloon and it does not pass through the kidneys, thus preventing renal side effects.
