A guiding sheath has a braided layer for improved deflection characteristics and ring electrodes for electrical sensing, mapping and visualization, wherein lead wires for the ring electrodes are passed through lumened tubing position under the braided layer in a proximal portion of the guiding sheath shaft and above the braided layer in a distal portion of the guiding sheath shaft. Moreover, the hemostatic valve includes an improved friction ring with air vents to reduce the risk of air being introduced into the valve.

Steerable guiding sheath with ring electrodes and related method of construction

Steerable guiding sheath with rack and pinion deflection mechanism

Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include a proximal section including a deflection mechanism for deflecting the proximal section, and a distal holding section extending distally of a distal end of the proximal section and defining a cavity therein for receiving an implantable leadless pacing device. The delivery device may include more than one deflection mechanism for deflecting the proximal section at multiple deflection regions. The delivery device may include more than one tubular member that are translatable relative to one another, and the one or more tubular members may include fixed curve portions. The delivery device may include an atraumatic or bumper tip at the distal end of the holding section.

Delivery devices and methods for leadless cardiac devices

A delivery device for a collapsible prosthetic heart valve includes an operating handle and a catheter assembly. The operating handle may include a housing defining a movement space therein, a carriage assembly moveable in a longitudinal direction within the movement space, a deployment actuator coupled to the housing and rotatable relative to the housing, and a coupling assembly rotationally fixed to the deployment actuator. The catheter assembly may include a first shaft around which a compartment is defined and a distal sheath operatively connected to the carriage assembly. Movement of the carriage assembly in the longitudinal direction in the movement space may move the distal sheath between the closed condition and the open condition. The coupling assembly may have an engaged position in which rotation of the deployment actuator moves the carriage assembly, and a disengaged position in which rotation of the deployment actuator does not move the carriage assembly.

Devices and methods for transcatheter heart valve delivery

A device and method for repairing a mitral valve leaflet. The deviceincludes a bodyhaving an annular walland at least one aperturethrough the annular wall. A deployment assemblymounted on the body includes at least one grasping wirearranged for sliding movement in the aperture. Movement of the deployment assemblyto a deployed position relative to the body causes a free end of the grasping wireto project out from the annular wallthrough the aperture, and movement of the deployment assembly to a retracted position relative to the body causes the free end of the grasping wireto not project out from the annular wall. In the deployed position, the grasping wiremay grasp and gather tissue of the leaflet

Apparatus and method for heart valve repair

An adjustment tool enables manipulation of a prosthetic anatomical device such as an annuloplasty ring. The tool includes a compression member which is operative for retarding rotation of the adjustment shaft to preclude inadvertent rotation thereof during use of the tool by the surgeon. A locking device is associated with the adjustment tool to enable the releasable attachment of the tool to the anatomical device during its adjustment by manipulation of the tool. The locking device is oriented into operative and inoperative positions by the engagement and disengagement of locking elements. A scale may be provided on the adjustment tool to assist a surgeon in determining the size or amount of adjustment to the size of the anatomical device during its adjustment.

Tool for the adjustment of a prosthetic anatomical device

A devicefor gathering tissue in a patient includes an elongated catheterand a capture assemblyat a distal portion of the catheter. The capture assembly has a closed sideand a doorrotatable between an open condition and a closed condition. The closed sideof the capture assemblyand the doorin the closed condition may collectively define a tissue capturing compartment. Movement of the doorfrom the open condition to the closed condition adjacent the tissue may capture a portionof the tissue in the tissue capturing compartment. A clip may then be applied from the capture assemblyto the captured tissueto hold the tissue substantially in a gathered configuration.

A devicefor repairing mitral valve leafletsincludes a jaw mechanismthat may be positioned adjacent a mitral valve leaflet. The jaw mechanismmay move between an open position and a closed position by pivoting a first jaw relativeto a second jaw. The first jawmay include a rivetthat may move from a stored position to an application position projecting away from the first jawwhen the jaw mechanismis moved from the closed to the open position. Closing the jawsabout a valve leafletcauses the rivetto pierce the leaflet. The jaw mechanismmay then be rotated to wind the leafletthereabout and again pierce the leaflet. The rivetmay then be released from the jaw mechanismand the deviceremoved from the patient.

An adjustable prosthetic anatomical holder system may include an adjustable annuloplasty ring, a ring holder, and a positioning handle. The adjustable annuloplasty ring holder facilitates placement and adjustment of the annuloplasty ring during a cardiac surgical procedure. An optional positioning handle holds the adjustable annuloplasty ring during placement and suturing of the ring. The ring holder is constructed from two members that are slidably fit together in telescopic arrangement to accommodate adjustment of the ring size.
