The established technique to inoculate primary invasive orthotopic bladder cancer xenografts requires laparotomy and mobilization of the bladder. This procedure inflicts significant morbidity on the mice, is technically challenging and time-consuming. We therefore developed a high-precision, percutaneous approach utilizing ultrasound guidance.

Non-invasive Monitoring and Imaging in Animal Research

All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Non-invasive technologies support the principles of 3Rs by enabling repeated data collection from the same animal without the need for euthanasia at multiple time points. These approaches reduce the number of animals required...

Minimally invasive transverse aortic constriction (MTAC) conserves the essentials of regular transverse aortic constriction (TAC) while eliminating the use of a ventilator with tracheal intubation. It proves to be a highly desirable method for high-throughput studies on left ventricular overload, particularly in translational studies.

Minimally invasive surgical (MIS) procedures rely on anatomical references to localize structures not directly visible to the surgeon. This manuscript describes a combined method of plane-by-plane dissection and sectional anatomy of fresh-frozen specimens to locate the structures at risk during MIS procedures.

Direct injection into the rat optic nerve is useful for regenerative research. We demonstrate a minimally-invasive technique for direct injection into a rat optic nerve that does not involve opening the skull. Using this method, surgical complications are minimized and recovery is more rapid.
FAQs
The sensing element detects changes in pressure, motion, electrical activity, or analyte concentration and converts them into signals that can be interpreted as physiological, biochemical, or biomechanical data. Miniaturization allows these components to operate through small access points or near the body surface. This design supports measurement while limiting tissue disruption and physiological disturbance.
Flexible probes and miniaturized devices can be positioned near relevant tissues or introduced through small access points, reducing the physical burden associated with measurement. Their compact form also supports repeated or continuous assessment rather than relying only on isolated observations. In bioengineering, these characteristics help balance measurement access with reduced discomfort and procedural risk.
The central distinction is the degree of tissue disruption and physiological disturbance required to obtain data. Minimally invasive approaches seek useful measurements through limited access, near-surface placement, miniaturized sensors, flexible probes, or imaging systems. Compared with conventional invasive methods, this can support repeated assessment with less discomfort and lower procedural burden, while still providing clinically relevant information.
Wireless communication can help transfer measurements from compact monitoring devices, while signal processing turns sensor outputs into interpretable information. Together, these technologies extend the usefulness of measurements collected over time and support real-time health management. Their development is also contributing to monitoring systems that can fit more naturally into personalized medicine and longitudinal studies.
Deployment generally involves selecting a miniaturized sensor, flexible probe, or imaging system suited to the target signal, then placing it near the body surface or introducing it through a small access point. The system measures pressure, motion, electrical activity, or analyte concentration and converts those changes into data for assessment, guidance, or follow-up.
Its applications include diagnosis, therapy guidance, postoperative care, and longitudinal studies. Repeated or continuous measurements can show how physiological, biochemical, or biomechanical signals change over time, while limited tissue disruption may make ongoing observation more practical. Bioengineers therefore use the approach to connect device design, measurement quality, and patient-centered monitoring needs.
By collecting physiological, biochemical, or biomechanical information repeatedly or continuously, minimally invasive systems can provide data that reflect an individual’s changing condition. Wireless communication and signal processing help make those data usable for timely interpretation. This combination supports the broader goal of tailoring assessment and management to ongoing measurements rather than relying only on occasional evaluations.
