The clinical application of electromagnetic and acoustic energies is an essential development moving away from classical invasive surgery towards a more patient friendly methodology using minimally or non-invasive treatment modalities.

Hans Wiksell has developed the ultrasonic aspirator "Sonocut", the kidney stone fragmentation device (ESWL) "Lithout" and a device for the treatment of benign prostatic hyperplasia based on computer controlled microwave heating (TUMT) called "ECP". More than 400 000 patients worldwide have been successfully treated with these instruments. Today Hans Wiksell is involved in developing new methods for breast cancer diagnosis and therapy.

Breast cancer is today the most common form of cancer in women. With incidences rising and mortality rates remaining virtually unchanged there is a substantial need for new treatment modalities. Working in close collaboration with medical experts Hans Wiksell is driving forward the development towards a more lenient and patient friendly way of breast cancer management.

Preferential Radiofrequency Ablation (PRFA) is a promising new technique for the minimally-invasive treatment of breast cancer. It has shown high success rates and low complication rates while achieving excellent cosmetic results.

Other projects include means to prevent possible tumor cell seeding during diagnostic procedures (AntiSeeding) as well as innovative developments regarding both fine needle aspiration (FNA) and core needle biopsy (CNB).

Diagnostic developments are implemented in a European Project (Fluodiamon) where Hans Wiksell acts as work package leader.
