Rupture of the arterial wall causes deflection in pressure time course during ex vivo balloon angioplasty [PDF]
, 1997 A relation between restenosis and arterial lesions resulting from balloon angioplasty has been suggested in literature. Nevertheless, it is unclear to what extent angioplasty-induced arterial wall lesions contribute to the occurrence of restenosis.

Pumping Patterns and Work Done during Peristalsis in Finite-length Elastic Tubes [PDF]
, 2019 Balloon dilation catheters are often used to quantify the physiological state of peristaltic activity in tubular organs and comment on their ability to propel fluid which is important for healthy human function. To fully understand this system's behavior, we analyzed the effect of a solitary peristaltic wave on a fluid-filled elastic tube with closed ...

Automatic catheter detection in pediatric X-ray images using a scale-recurrent network and synthetic data [PDF]
, 2018 Catheters are commonly inserted life supporting devices. X-ray images are used to assess the position of a catheter immediately after placement as serious complications can arise from malpositioned catheters. Previous computer vision approaches to detect catheters on X-ray images either relied on low-level cues that are not sufficiently robust or only ...
