  • Patent number: 12089870
    Abstract: Systems, devices, and methods for providing access to the heart. The system includes an intracardiac access device comprising an elongate member having a channel extending between a distal end and a proximal end thereof. The intracardiac access device is configured to be advanced through an extrapericardial penetration in the left atrial wall without penetrating the pericardium of the heart. An optional procedural device is configured to be advanced through the channel of the intracardiac access device into an internal chamber of the heart and configured to perform a surgical procedure in the internal chamber of the heart. A working channel of an optional suprasternal access device is configured to facilitate access of the intracardiac access device into the body of the patient by providing a path from a suprasternal opening to a position adjacent the roof of the left atrium.

  • Publication number: 20220346772
    Abstract: Systems, devices, and methods for endoscopically retracting a target tissue. The device includes a first shaft and a second shaft slidably coupled thereto. An internal member extends in a transverse direction from the first shaft and is configured for advancement through a penetration in the target tissue to atraumatically engage a distal surface of the target tissue after being advanced therethrough. A pair of external members extend from the second shaft generally parallel to the transverse direction. The external members are spaced apart and are configured to atraumatically engage a proximal surface of the target tissue when the internal member is moved longitudinally relative to the external members. The internal member applies traction to the target tissue when retracted past the pair of external members, which apply counter-traction to the target tissue on opposing lateral sides of the internal member, to re-shape the target tissue and enable subsequent suture placement.

  • Publication number: 20210321996
    Abstract: Systems, devices, and methods for performing catheter-based procedures in the heart. In specific embodiments a procedural catheter is introduced into the mediastinum from a suprasternal access site. The procedural catheter is passed through a wall of the heart, preferably at an extrapericardial location on the atrial dome. The procedural catheter is used to perform a procedure in the heart such as mitral valve repair or replacement, using remote catheter visualization techniques.
