Disposable, single use, non-invasive device requiring no fluoroscopy and no IV contrast to evaluate the success of angioplasty.
ANGIO-SUCCESS
Currently, evaluation involves either invasive, time consuming placement of a pressure transducer along with administration of IV medication or administering IV contrast under fluoroscopy to visually make a judgment as to angioplasty adequacy.
The ANGIO-SUCCESS device is placed externally between the catheter/sheath and flush syringe. When the catheter is flushed with sterile saline, it measures quantitative change in resistance both before and after angioplasty.
The use of this device offers time savings as well as decreased use of IV contrast with its potential adverse effects of renal failure, anaphylactoid reaction, skin burns, and potential cancer from ionizing radiation.
The use of ANGIO-SUCCESS will decrease radiation exposure to physicians, medical personnel, and patients.
This patent describes a simple, molded plastic device, which would be attached to the Luer-lock end of a syringe.
The resistance to flow is measured by the device. By simply flushing the catheter prior to and after angioplasty, which is a normal part of the procedure, a pressure gradient change can be easily observed.
The ANGIO-SUCCESS device does not provide a number, but a percent gradient change from before to after angioplasty. The device will be marked 0, 25, 50, 100; corresponding to the different pressure differentials realized post-angioplasty. Only after an acceptable preliminary is reached would it be necessary to perform the “completion angiogram” utilizing intravenous contrast under fluoroscopic guidance.
To prevent unnecessary radiation exposure to patients and medical personnel. To decrease the chance of renal failure in patients undergoing contrast studies involving angioplasty.
