Abstract
Intravascular catheters that include a handle assembly with first and second handle actuators, where the actuators are adapted to separately control inner and outer catheter shafts in at least one of axial displacement, deflection, or rotation. The catheters may also include a medical tool secured to the outer shaft.
Claims20
An intravascular catheter, comprising:
- an outer shaft with a proximal region secured to a handle assembly;
- a medical tool axially secured at or adjacent a distal end of the outer shaft;
- and
- an inner shaft disposed within the outer shaft, the inner shaft having a proximal region that is secured to the handle assembly,
- the handle assembly including a first handle actuator in operable communication with the outer shaft such that actuation of the first handle actuator relative to a second handle actuator rotates the outer shaft and medical tool relative to the inner shaft,
- the second handle actuator being in operable communication with the inner shaft such that actuation of the second handle actuator deflects the inner shaft and thereby causes deflection of the outer shaft, wherein the first handle actuator and the second handle actuator are disposed coaxially.
3 more elements
A steerable catheter body, comprising:
- a catheter shaft comprising braided material;
- and
- at least one tensioning member, wherein a distal region of the tensioning member is interwoven in the braided material to help secure a distal end of the at least one tensioning member at a location of the steerable catheter body.
A steerable medical member, comprising:
- a deflectable catheter body with a deflectable section;
- and
- at least first and second tensioning members disposed adjacent the deflectable catheter body, wherein in the deflectable section the first and second tensioning members are closer together in degrees than in a proximal section proximal to the deflectable section.
