Project overview
Penile clamps are often used to prevent urinary leakage in males with incontinence following prostatectomy. However to ensure that the urethra is fully closed, existing designs apply large forces to the penile tissues, which can cause damage to the vulnerable skin and soft urological tissues. It is evident that existing technology, based on generic designs, and practice is not fit for purpose. Understanding the biomechanics at the device-tissue interface will provide a means to predict this risk.
A combined approach involving computational modelling (FEA), biophysical measurements and imaging (MRI) has been adopted to predict these interface conditions.
Goals
• Predict the effective stresses and strains in various soft tissue layers when compression is applied using five generic clamp designs
• Monitor parameters of tissue pressures and blood flow impedance during application of clamps and the subsequent changes in pro-inflammatory cytokines. These measures could be used as indicators of skin health
• Estimate the tissue deformations resulting from the application of existing clamp designs
• To design a novel safe penile clamp and clinical guidelines, co-designed with prostate cancer patients, clinicians and engineers
