Biomedical / Devices

In recent years, our new biomedical devices have included a microscopy system that performs real-time particulate analysis, a lesion depth sensor for cardiac ablation, and a perineal massager for easing childbirth anxiety.

Title	Inventors	Case #	Description	Podcasts
High-intensity ultrasound improves scar ablation	Wu Langevin	370	Highly localized acoustic energy provides rapid scar ablation without the high recurrence rates and side effects of traditional treatments. (Also in Therapeutics)
Noninvasive pulmonary airway resistance measurement system	Bates	168	Unrestrained video-assisted plethysmography provides high-throughput, non-destructive monitoring of airway resistance changes in mice.
Hybrid design knee joint prosthesis	Beynnon Incavo	174	Hybrid design for knee prostheses offers improved long-term stability through larger surface area for cement & undersurface area for bone ingrowth. (Also in Therapeutics)
Depth sensor improves efficacy of cardiac ablation	Spector	302	Catheter-mounted sensor enables cardiologists to accurately determine lesion depth during cardiac ablation. (Also in Therapeutics)
Knee joint prosthesis with a femoral component which links the tibiofermoral axis with the patellofemoral axis of rotation	Beynnon Incavo Coughlin	143	Kinematic studies of cadaver knee specimens can be used to develop an optimal femoral epicondylar axis for prostheses, providing a more normal range of motion. (Also in Therapeutics)
Perineal massager eases childbirth anxiety	Young	288	Perineal massage in late-stage pregnancy can relieve anxiety & reduce the need for episiotomies & Caesarian deliveries. However, the technique is difficult & often performed incorrectly. Unique device for maternal self-care is simple to use & inexpensive to manufacture.
