Abstract
The present disclosure relates to a delivery system, a catheter system and a method for the minimally invasive application of prostheses to an individual in need thereof and a method for loading a prosthesis onto a catheter system and/or a delivery system.
Claims21
A method for delivering a prosthetic heart valve to a heart of a patient using a catheter system, the method comprising:
- inserting an introducer comprising a sheath into the patient;
- advancing a delivery catheter and a steering catheter in the introducer, the delivery catheter configured to deliver the prosthetic heart valve and having a proximal end and a distal end, the distal end comprising a tip that includes a first sleeve movable relative to a second sleeve in a proximal-distal direction, a middle section configured to be uncovered when the first sleeve is in a proximal-most position with respect to the second sleeve, and a holder disposed in the second sleeve, the second sleeve positioned proximal to the first sleeve and the first sleeve having an open end facing in a proximal direction;
- manipulating an integrated handle to cause the steering catheter to deflect to steer the delivery catheter, the integrated handle comprising a delivery handle portion and a steering handle portion comprising a housing, the housing of the steering handle portion sized and configured to receive the delivery handle portion, the integrated handle configured to control movement of the delivery catheter and the steering catheter, independently;
- and
- causing an actuator movably coupled to the delivery handle portion and configured to move with respect to the delivery handle portion to move to manipulate the first sleeve relative to the second sleeve and the holder while the delivery handle portion is received by the housing of the steering handle portion,
- wherein the steering catheter is fixedly connected to the steering handle portion and the delivery catheter is fixedly connected to the delivery handle portion, and
- wherein the steering catheter and the delivery catheter are selectively coaxially and rotationally independently movable.

A method for delivering a prosthetic heart valve to a heart of a patient using a catheter system, the method comprising:
- inserting an introducer comprising a sheath and a crimping section proximal to a sheath into the patient, the crimping section having an inner diameter that decreases in a distal direction;
- advancing a delivery catheter and a steering catheter in the introducer, the delivery catheter configured to deliver the prosthetic heart valve and having a proximal end and a distal end, the distal end comprising a tip that includes a first sleeve movable relative to a second sleeve in a proximal-distal direction, and a holder disposed in the second sleeve, the second sleeve positioned proximal to the first sleeve and the first sleeve having an open end facing in a proximal direction,
- manipulating an integrated handle to cause the steering catheter to deflect to steer the delivery catheter, the integrated handle comprising a delivery handle portion fixedly connected to the delivery catheter and a steering handle portion comprising a housing fixedly connected to the steering catheter, the housing of the steering handle portion sized and configured to receive the delivery handle portion, and the integrated handle configured to control movement of the delivery catheter and the steering catheter, independently;
- and
- causing an actuator movably coupled to the delivery handle portion and configured to move with respect to the delivery handle portion to move to manipulate the first sleeve relative to the second sleeve and the holder while the delivery handle portion is received by the housing of the steering handle portion,
- wherein the delivery catheter and the steering catheter are simultaneously introducible into the crimping section of the introducer;
- and
- wherein the steering catheter, the delivery catheter, and the sheath are rotationally independently movable when the steering catheter and the delivery catheter are simultaneously disposed in the sheath.
