New camera a Leap forward in intravascular surgery
Medical practitioners can for the first time view inside veins and arteries, thanks to breakthrough new camera technology. A single-use, high-definition miniature camera, known as “Leap”, represents a watershed moment for intravascular surgery, according to engineers at Cambridge Consultants. Process Industry Forum gives you the inside view – quite literally – on this new innovation.
Visualisation for challenging cardiovascular surgery
Leap builds on the latest generation of Omnivision's sub-millimetre cameras, enabling surgeons to visualise parts of the anatomy that are currently inaccessible with today’s imaging techniques. With potential for even smaller cameras on the horizon, this highly miniaturised ‘chip-on-tip’ architecture features a 400 x 400 pixel image (0.16 megapixels) as a standard capability.
This represents an order of magnitude improvement over standard fibre-optic angioscopes. Chip-on-tip refers to the location of the imaging sensor at the distal end of the endoscope, in contrast to traditional fibre bundles which transmit light to large, external processing towers.
In the future, Leap technology could be combined with Cambridge Consultants’ ‘super-resolution’ image processing to increase the resolution further to 1600 x 1600 pixels (2.6 megapixels). This state-of-the-art, proprietary technique harnesses deep learning to enhance low resolution images without the blurring associated with traditional upscaling and will ultimately provide visualisation for the most challenging cardiovascular surgery.
Inexpensive single-use endoscope
Despite the ability to provide unique predictive information, current surgical endoscopes are not widely used in angioscopy due to poor flexibility, a limited field of view and low resolution. At 1.35 mm in diameter, the Leap early prototype is small and flexible enough for use in a procedure such as intracoronary angioscopy.
Leap increases the information available to surgeons with new functionality, such as enabling tissue classification or direct imaging of non-standard vascular occlusions. Moving beyond the traditional endoscope, inspection with a Leap device could be paired with today’s leading technologies, such as IVUS (Intravascular Ultrasound) and OCT (Optical Coherence Tomography), enabling enhanced diagnostic techniques during surgery.
Existing endoscopes also carry an elevated risk of infection and device damage due to inadequate sterilisation between procedures. Leap overcomes a number of these barriers, being an inexpensive, single-use endoscope and can be operated from a standard computer, not relying on the availability of large and expensive operating room infrastructure.
Due to the falling costs of chip-on-tip technology, the expense associated with traditional endoscope systems are set to significantly reduce. This is achieved with the introduction of an economical, reposable device, removing the need for sterilisation and maintenance.
New level of advanced imaging in intravascular procedures
“We have combined our intravascular device experience with our knowledge of micro‑optics, systems engineering and AI, in conjunction with external manufacturing partners,” said Simon Karger, Head of Surgical and Interventional Products at Cambridge Consultants. “The result is an economically viable, disposable camera system that is small enough to fit into the working channel of a typical vascular catheter.
“For the first time, Leap offers practical, direct visualisation in the procedure room and a platform for integration of new configurations, sensor types and imaging modalities (such as spectroscopy). This can enable a new level of advanced imaging in intravascular procedures and an unparalleled surgical experience” he added.
