Abstract
Medical delivery system for accessing a tricuspid valve via an inferior vena cava, including an outer guide catheter, an inner guide catheter and an interventional catheter. The first deflection portion of the outer guide catheter is steerable to define a first outer-guide-catheter curve and the second deflection portion of the outer guide catheter is steerable to define a second outer-guide-catheter curve and the first deflection portion of the inner guide catheter is steerable to define a first inner-guide-catheter curve.
Claims20
A method of repairing a tricuspid valve, comprising:
- providing a medical delivery system for accessing the tricuspid valve, including
- an outer guide catheter having a proximal end portion, a first deflection portion, a second deflection portion, and a distal end portion each aligned in series along a length of the outer guide catheter, and having a steering assembly comprising a first steering mechanism and a second steering mechanism, the outer guide catheter defining a lumen extending from the proximal end portion to the distal end portion,
- an inner guide catheter positioned coaxially within the lumen of the outer guide catheter, the inner guide catheter having a proximal end portion, a first deflection portion, and a distal end portion each aligned in series along a length of the inner guide catheter, and having a steering assembly comprising a first steering mechanism, the inner guide catheter defining a lumen extending from the proximal end portion to the distal end portion, and
- an interventional catheter positioned coaxially within the lumen of the inner guide catheter, the interventional catheter having a proximal end portion and a distal end portion, and having an implantable fixation device coupled to the distal end portion;
- delivering the outer guide catheter to a right atrium via an inferior vena cava;
- actuating the first steering mechanism of the outer guide catheter to steer the first deflection portion of the outer guide catheter such that the distal end portion of the outer guide catheter moves within the right atrium relative the tricuspid valve;
- advancing the inner guide catheter longitudinally relative the outer guide catheter such that the first deflection portion of the inner guide catheter extends distally from the distal end portion of the outer guide catheter;
- actuating the first steering mechanism of the inner guide catheter to steer the first deflection portion of the inner guide catheter such that the distal end portion of the inner guide catheter moves within the right atrium relative the tricuspid valve;
- aligning the implantable fixation device with the tricuspid valve by operating the first and second steering mechanism of the outer guide catheter and the first steering mechanism of the inner guide catheter;
- and
- deploying the implantable fixation device to repair the tricuspid valve.
