    Abstract: Pinch devices and access systems that can be used to secure a prosthetic heart valve to a heart valve annulus and to treat valvular insufficiency. A pinch device can be a separate expandable element from the prosthetic heart valve that is first advanced to the annulus and deployed, after which an expandable prosthetic heart valve can be advanced to within the annulus and deployed. The two elements can clamp/pinch the heart valve leaflets to hold the prosthetic heart valve in place. The pinch device can have a flexible, expandable annular frame. A combined delivery system can deliver the pinch device and prosthetic heart valve with just a single access point and aid more accurate coaxial deployment. The pinch device can be mounted near distal end of an access sheath, and a catheter for delivering the prosthetic heart valve can be passed through a lumen of the same access sheath.

    Abstract: Disclosed embodiments of introducer devices provide hemostatic sealing and allow a delivery catheter to be inserted through the introducer seals without the use of a separate loader device that covers a medical device that is mounted on the catheter. Some disclosed introducers comprise a housing, a distal sheath extending distally from the housing and adapted to be inserted into a patient's vasculature, a distal hemostatic seal mounted within the housing and a proximal hemostatic seal mounted within the housing, and a slidable tube positioned within the housing that is movable longitudinally relative to the distal hemostatic seal between a proximal position and a distal position, wherein in the proximal position a distal end of the tube is positioned proximal to the distal hemostatic seal with the distal hemostatic seal closed, and wherein in the distal position the distal end of the tube extends through the distal hemostatic seal.

    Abstract: An apparatus for delivering a prosthetic heart valve includes a steerable guide catheter, a balloon catheter, and a flex indicator. The guide catheter has a handle and a guide tube extending from the handle. The guide tube has a distal end portion comprising a steerable section. The guide catheter further includes an adjustment mechanism on the handle and a pull wire connecting the adjustment mechanism to the steerable section for changing flexion of the steerable section. The balloon catheter includes a shaft extending coaxially through the guide tube. The shaft includes a proximal end portion and a distal end portion. The balloon catheter further includes a balloon mounted on the distal end portion of the shaft. The flex indicator moves relative to the handle upon adjustment of the adjustment mechanism. The handle includes visual indicia adjacent the flex indicator to provide visual indication of the flexion of the steerable section.
