Appl. No.:

16/437809

Inventors:

- Galena MO, US
Donald John Rohde - Springfield MO, US
Christopher Conti - Galena MO, US

International Classification:

G06T 7/00
G06T 7/13
G06T 7/174
A61F 2/90

Abstract:

Systems and methods are described for capturing images of articles under test and processing the images to automatically detect the failure of a test article. The described methods include optimizing image capture to allow for the use of low cost imaging devices instead of high speed cameras or other expensive equipment. The described methods also include several methods for processing the images to identify the occurrence of a failure event.

International Classification:

G01M 99/00

Abstract:

A method of determining the endurance limit of an implantable medical device is disclosed. The method utilizes a mock vessel that has a compliance that is higher or lower than the normal compliance of a human vessel for which the device is to be used. The device is deployed into the mock vessel and a curable liquid is used to form a layer over the device on the surface of the lumen of the mock vessel. High pressure pulsatile pressurization is applied to the lumen of the mock vessel to cause a failure of the implantable medical device. The amount and cycles of pressure necessary to cause a failure may be used to determine the endurance limit of the implantable medical device.

Abstract:

The invention generally relates to systems and methods for stress testing to failure tubular mesh devices, specifically, one or more stents or mesh grid tubes. A radial compression method of stress to fatigue is developed by placing a tubular medical implant within a lower than normal compliance test vessel. A radial expansion method of stress to fatigue is developed by placing higher than normal compliance tubes within a tubular medical implant. A method for radial expansion and radial compression is conducted by placing a higher than normal compliance tube through the mesh device and the placing the tube and device within a lower than normal compliance test vessel. Each method is tested on a tester that operates by delivering pulsatile flow with varying pressures, frequencies and testing parameters. Fracture of the test subject is visualized by high speed camera.
