Abstract
A medical probe includes a shaft for navigation in a patient body, and first and second deflection mechanisms. The shaft ends with a flexible section and a spring, followed by a rigid distal tip having one or more medical devices coupled thereto. The first deflection mechanism is configured to deflect the flexible section relative to the shaft. The second deflection mechanism is configured to deflect the distal tip relative to the first flexible section by using the spring.
