Hansen Medical's New Focuses on the Uses of Robotic Catheterization

Looking to evaluate its new vascular robot, Hansen Medical has carried out a pre-clinical in-vivo study. According to the company, this study demonstrated improvements in catheter navigation, reductions in vessel trauma during catheter manipulation, and improvements in access time for some vessels.

Experts from the medical field believe that robotic catheterization has the potential to be less traumatic to vascular anatomy when compared to manual catheterization. It is also believed that the use of this vascular robot may reduce harmful radiation exposure to both the patient and clinician.
Alan Lumsden, M.D. and Jean Bismuth, M.D., from the DeBakey Heart & Vascular Center at Methodist Hospital in Houston guided the pre-clinical in-vivo study. Apart from angiographic evidence of trauma, the safety was also evaluated through both gross visual examination and histopathology of target vessels.
"We are extremely encouraged by the results of this pre-clinical in-vivo study, as this accomplishment brings us one step closer to the introduction of a new Hansen Medical robot and catheters for use in the vascular system,' said Robert Mittendorff, M.D., vice president of marketing and business development at Hansen Medical. 'We believe our new robot and its clinical capabilities for complex vascular procedures will open up significant new opportunities"
Incorporating a removable, robotically shapeable diagnostic catheter inside of a robotically shapeable sheath, the pre-clinical study featured the use of a new, smaller vascular robotic catheter. Specifically, a single vascular catheter was able to successfully navigate the aorta and access several primary and secondary branches. In several target vessels, three stents were successfully delivered through the robotic sheath.
Recently, the company announced the results from a pre-clinical study showing that use of its Sensei Robotic Catheter System in procedures for treatment of vascular disease has the potential to reduce procedure time by 80 percent. The study showed that robotic cannulation (insertion of a catheter into a branch vessel) for aneurysm repair was significantly faster than standard cannulation using conventional endovascular catheters for all target vessels.
