  • Catheter delivery system for heart valve prosthesis
    Patent number: 9878127
    Abstract: The invention relates to an operating handle (10-1, 10-2) for manipulating a catheter tip (80-1, 80-2) of a catheter delivery system. The operating handle (10-1, 10-2) comprises a hand grip (11) designed to be held by a user, and a manipulating part (12) axially aligned with the hand grip (11). The manipulating part (12) is rotatable relatively to the hand grip (11) about a longitudinal axis (L) defined by the operating handle (10-1, 10-2). The operating handle (10-1, 10-2) comprises at least one sliding member (30, 40) operatively linked with the manipulating part (12) by means of a cam mechanism (50) such that, upon rotation of the manipulating part (12) relative to the hand grip (11), the at least one sliding member (30, 40) moves axially in the direction of the longitudinal axis (L).

  • Catheter system for introducing an expandable heart valve stent into the body of a patient
    Patent number: 9510947
    Abstract: The invention relates to catheter system for introducing an expandable heart valve stent (150) into the body of a patient, the catheter system comprising: a catheter tip (10) having a seat portion for accommodating the stent (150) in its collapsed state and a stent holder (15) for releasably fixing the stent (150), wherein the seat portion is constituted by a first sleeve-shaped member (11) and a second sleeve-shaped member (21), said sleeve-shaped members (11, 21) being moveable relative to each other and relative to the stent holder (15), and a catheter shaft (30) for connecting the catheter tip (10) to a handle (70).
