Minimally invasive treatment of venous insufficiency using endovenous laser ablation
… resulting in improved QoL. Additionally this treatment has been shown to be highly cost-effective. Despite these advantages, surgery is associated with significant post-operative morbidity; in the form of pain and immobility, even in the absence of complications. Additionally, in the long …

New minimally-invasive laser treatment in orthopaedics on spinal deformations and bone tumours
Three completely new, minimally-invasive laser operation techniques were developed and extensive investigations were carried out for a clinical application in orthopaedics. With a focus on laser tissue interactions, this work covers a broad range of different applications from cw to femtosecond …

Effective Cancer Therapy Design Through the Integration of Nanotechnology
Laser therapies can provide a minimally invasive treatment alternative to surgical resection of tumors. However, therapy effectiveness is limited due to nonspecific heating of target tissue, leading to healthy tissue injury and extended treatment durations. These therapies can be further …

Measurement of tissue optical properties during mechanical compression using swept source optical coherence tomography
Laser-based photo-thermal therapies can provide minimally-invasive treatment of cancers. Their effectiveness is limited by light penetration depth in tissue due to its highly scattering properties. The highly disordered refractive index distribution in tissue leads to multiple-scattering of …

Investigations of Ultrasound-Guided Histotripsy Ablation for Soft Tissue Sarcomas, Osteosarcomas, and Brain Tumors
Histotripsy is a non-thermal, non-invasive focused ultrasound therapy using controlled acoustic cavitation to mechanically disintegrate tissue into an acellular homogenate. Histotripsy applies microsecond-length, high pressure (> 10 MPa) pulses to initiate the rapid expansion and collapse of nuclei …

Development of Feedback Microwave Thermotherapy in Symptomatic Benign Prostatic Hyperplasia.
… this thesis was to evaluate ProstaLund Feedback Treatment® (PLFT®) and the CoreTherm® device with regard to biophysics, mechanisms of action, treatment indications, additional techniques, efficacy and safety in the treatment of patients with benign prostatic hyperplasia (BPH). The application of …

Single Walled Carbon Nanohorns as Photothermal Absorbers, and Incorporation of Spatial Digital Image Analysis into Cancer Diagnostics and Therapy
… therapy is an actively researched cancer treatment alternative to chemotherapy and resection due to its potential as a minimally invasive treatment with fewer health complications than high energy radiation therapies. The effectiveness of photothermal therapy may be enhanced with the use …

Novel Systems Physiology Instrumentation: Addressing Limitations in Heart Failure Reseearch
… technology for electromechanical mapping, and treatment of arrhythmias associated with heart failure. First, I present a miniature, implantable pacemaker for mice as a tool for investigating pacing-induced heart failure and cardiac memory. In previous studies, reliable, chronic pacing in mice …

Scattered radiation in cone beam computed tomography : analysis, quantification and compensation
For imaging during minimally-invasive treatment in the so-called catheter laboratory conventional X-ray projection imaging is classically used. Particularly in cardio-vascular angiography and neuroradiology, so-called C-arm systems are used, enabling a flexible positioning of X-ray tube and …

Optical diagnostics for oral and gastrointestinal tract pathologies
… Early diagnosis can improve patient outcomes by minimally invasive treatment, reduced mortality rate and improved post-treatment life quality. Despite the availability of advanced technology and diagnostic tools, early detection of OPMD is limited by reliance on invasive biopsies and …

Interstitial laser thermotherapy (ILT) of breast cancer - Methodology and immunological responce
… by surgical resection about two weeks later. Pre-treatment US estimated the average tumor diameter to be 14 (range 5-35) mm. ILT was performed at 48Cº for 30 minutes under local anesthesia. Three patients were radically treated with ILT and the average tumor necrosis was 33% (0-100). Microscopic …
