Heart valve implants with side slits
A cardiac implant system including a cardiac implant such as an annuloplasty ring, a prosthetic heart valve, or a valved conduit pre-assembled at the time of manufacture with devices for securing the implant to a heart valve annulus using knotless suture fasteners. The knotless suture fasteners may be embedded within a pliant sealing edge of the cardiac implant, or they may be positioned adjacent to the sealing edge. The knotless suture fasteners are spring-biased so as to grip onto annulus anchoring sutures pass to therethrough upon removal of a restraining device, such as a hypotube inserted within the suture fasteners. Guide tubes are assembled in line with the suture fasteners to permit introduction of suture snares that pass through the suture fasteners and through the sealing edge to facilitate capture of the pre-installed annulus anchoring sutures.
Chordae tendineae management devices for use with a valve prosthesis delivery system and methods of use thereof
Embodiments hereof relate to methods of delivering a valve prosthesis to an annulus of a native valve of a heart, the native valve having chordae tendineae. A chordae management catheter is positioned within a ventricle of the heart, the chordae management catheter having a displacement component at a distal end thereof. The displacement component has an annular shape and defines a central lumen therethrough. The displacement component is radially expanded to push chordae tendineae within the ventricle radially outward. A valve delivery system is introduced into the ventricle of the heart via a ventricular wall of the heart. The valve delivery system has the valve prosthesis at a distal portion thereof. The valve delivery system is advanced through the central lumen of the radially expanded displacement component towards the annulus of the native valve of the heart. The valve prosthesis is deployed into apposition with the annulus of the native valve.
MEDIASTINUM ACCESS DEVICES AND METHODS
Devices and methods are described for accessing the mediastinum without an intercostal incision and without deflating the lungs. In some embodiments, the devices and methods facilitate mediastinal access via a single percutaneous needle puncture. In some embodiments, a first puncture below the ribs or sternum, and a second puncture that is intercostal are used. Devices and methods to facilitate concurrent access to the pericardial and mediastinal spaces are also described. Multiple minimally invasive procedures are described that advantageously utilize the pericardial and mediastinal space access procedures.
Tricuspid Retractor Blade Assembly
A retractor with a specialized blade head assembly. The blade head assembly has a central plate. The central plate extends between a first side edge and a second side edge. A first rotatable arm is attached to the first side edge with a first hinge joint. A second rotatable arm is attached to the second side edge with a second hinge joint. Both rotatable arms can be rotated about the hinge joints. Both the first hinge joint and the second hinge joint are friction hinges that require a threshold force to move. An elongated shaft interconnects with the central plate at a pivot joint. The elongated shaft can be attached to the blade head assembly after the blade head assembly has been inserted into a patient’s body.
STERNAL ASCENDER APPARATUS
A sternal elevator apparatus is disclosed. The sternal elevator may include a panel, a support beam traversing the panel, and a post coupled to a proximal end of the panel. The apparatus may also include an indicator handle coupled to the sternal elevator, an actuator drive pivotably coupled to the indicator handle, and a housing movably coupled to the actuator drive. The sternal elevator apparatus may have an actuator drive incorporating a linear rack. The housing further may include a cylindrical gear where the cylindrical gear is engaged with the linear rack.
MINIMALLY INVASIVE SURGICAL SUTURING DEVICE WITH IMPROVED VISUALIZATION
A suturing device is disclosed. The suturing device has a guide tip. The guide tip has first and second framing arms that define a viewing port from a first orientation. The guide tip also has proximal and distal ends of the guide tip which, with the first and second framing arms, define a tissue bite area from a second orientation. The suturing device also has a ferrule holder located in the distal end of the guide tip and centered relative to the first orientation. The suturing device further has a needle movable within the guide tip along a path through the tissue bite area and centrally viewable in the viewing port relative to the first orientation.
STERNAL ASCENDER APPARATUS
A sternal elevator apparatus is disclosed. The sternal elevator may include a panel, a support beam traversing the panel, and a post coupled to a proximal end of the panel. The apparatus may also include an indicator handle coupled to the sternal elevator, an actuator drive pivotably coupled to the indicator handle, and a housing movably coupled to the actuator drive. The sternal elevator apparatus may have an actuator drive incorporating a linear rack. The housing further may include a cylindrical gear where the cylindrical gear is engaged with the linear rack.
Percutaneous papillary muscle relocation
A system for treating mitral regurgitation may include an outer sheath having a lumen extending to a distal end of the outer sheath, an intermediate sheath slidably disposed within the lumen of the outer sheath, the intermediate sheath having a lumen extending to a distal end of the intermediate sheath, and an inner sheath slidably disposed within the lumen of the intermediate sheath, wherein the inner sheath includes a first anchor disposed within a lumen of the inner sheath, the first anchor being configured to penetrate and secure to a first papillary muscle. The intermediate sheath may include a tissue grasping mechanism at the distal end of the intermediate sheath, the tissue grasping mechanism being configured to hold and stabilize the first papillary muscle for penetration and securement of the first anchor to the first papillary muscle.
Thoracic structure access apparatus, systems and methods
A thoracic structure access system for retracting biological tissue and providing access to internal biological structures; particularly, intrathoracic structures, e.g., the heart and internal mammary arteries, to facilitate entry through the biological tissue with surgical instruments and interaction of the surgical instruments with the intrathoracic structures during a thoracic surgical procedure; particularly, minimally invasive CAGB and OPCAB procedures. The system facilitates coronary artery bypass graft (CAGB and OPCAB) procedures via a simple incision at a transxiphoid incision site and, hence, without fully transecting the sternum, i.e., performing a full sternotomy, or performing a thoracotomy. The system includes modular retractor and retention arm assemblies in communication with a ratchet assembly. When the system is disposed proximate a transxiphoid incision site and the modular retractor and retention arm assemblies are releasably engaged to opposing biological tissue portions at the transxiphoid incision site, the ratchet assembly can be actuated to apply opposing forces to the biological tissue portions to provide an access space at the transxiphoid incision site.
Trans-septal closure and port device
A septal closure and port device for implantation in the atrial septum of a patient's heart includes an expandable frame with a central portion defining a lumen, and first and second opposing end portions. The frame can expand and contract between a compressed, tubular configuration for delivery through the patient's vasculature and an expanded configuration in which the first and second end portions extend radially outwardly from the opposite ends of the central portion. The device can also have a valve member supported on the frame and positioned to block at least the flow of blood from the left atrium to the right atrium through the lumen of the frame. The valve member permits a medical instrument to be inserted through the lumen and into the left atrium, for performing a subsequent medical procedure in the left side of the heart.
