PLoS ONE, 2020 Background Restenosis remains a significant problem in endovascular therapy for hemodialysis vascular access. Drug-coated balloon (DCB) angioplasty decreases restenosis in peripheral and coronary artery diseases.

Lumen Shape Reconstruction using a Soft Robotic Balloon Catheter and Electrical Impedance Tomography [PDF]
, 2022 Incorrectly sized balloon catheters can lead to increased post-surgical complications, yet even with preoperative imaging, correct selection remains a challenge. With limited feedback during surgery, it is difficult to verify correct deployment. We propose the use of integrated impedance measurements and Electrical Impedance Tomography (EIT) imaging to

A multiscale model of vascular function in chronic thromboembolic pulmonary hypertension [PDF]
, 2021 Chronic thromboembolic pulmonary hypertension (CTEPH) is caused by recurrent or unresolved pulmonary thromboemboli, leading to perfusion defects and increased arterial wave reflections. CTEPH treatment aims to reduce pulmonary arterial pressure and reestablish adequate lung perfusion, yet patients with distal lesions are inoperable by standard surgical

New England Journal of Medicine, 1994 BACKGROUND Balloon-expandable coronary-artery stents were developed to prevent coronary restenosis after coronary angioplasty. These devices hold coronary vessels open at sites that have been dilated. However, it is unknown whether stenting improves long-

A thermodynamic framework for unified continuum models for the healing of damaged soft biological tissue [PDF]
, 2021 When they are damaged or injured, soft biological tissues are able to self-repair and heal. Mechanics is critical during the healing process, as the damaged extracellular matrix (ECM) tends to be replaced with a new undamaged ECM supporting homeostatic stresses. Computational modeling has been commonly used to simulate the healing process.

Transcutaneous Puncture of an Undeflatable Coronary Angioplasty Balloon Catheter
Case Reports in Cardiology, 2018 This case report describes a quick and safe method to successfully retrieve an undeflatable angioplasty balloon via the transradial access site. The article also presents potential mechanisms of contrast media entrapment and bench tests of guidewire ...

Efficient isogeometric thin shell formulations for soft biological materials [PDF]
Biomech Model Mechanobiol (2017) 16:1569, 2016 This paper presents three different constitutive approaches to model thin rotation-free shells based on the Kirchhoff-Love hypothesis. One approach is based on numerical integration through the shell thickness while the other two approaches do not need any numerical integration and so they are computationally more efficient. The formulation is designed

Robust Landmark-based Stent Tracking in X-ray Fluoroscopy [PDF]
arXiv, 2022 In clinical procedures of angioplasty (i.e., open clogged coronary arteries), devices such as balloons and stents need to be placed and expanded in arteries under the guidance of X-ray fluoroscopy. Due to the limitation of X-ray dose, the resulting images are often noisy.

Gradient-enhanced continuum models of healing in damaged soft tissues [PDF]
Biomechanics and Modeling in Mechanobiology, Springer Verlag,
2019, 18 (5), pp.1443-1460, 2019 Healing of soft biological tissue is the process of self-recovering or self-repairing the injured or damaged extracellular matrix (ECM). Healing is assumed to be stress-driven, with the objective of returning to a homeostatic stress metrics in the tissue after replacing the damaged ECM with new undamaged one.
