  • Patent number: 9517129
    Abstract: An implant delivery system comprising a catheter including at least one lumen, an implant configured to be received in the lumen, and a latching mechanism configured to be received in the implant. The latching mechanism may be configured to releasably couple the implant to a delivery wire and to transmit a torque through the delivery wire to cause at least a portion of the implant to rotate. The an implant may comprise a shaft, a spacer configured to interact with at least a portion of at least one cusp of a heart valve to at least partially restrict a flow of blood through the heart valve in a closed position, a garage configured to couple the spacer to a first end region of the shaft, and at least one anchor mechanism. The garage may define a cavity configured to receive the latching mechanism and to increase rotational and translational stability of the latching mechanism.

  • Publication number: 20140276395
    Abstract: A catheter according to one embodiment may be configured to extend through a transseptal puncture site, a left atrium, and into a left ventricle. The catheter may comprise a shaft defining at least one lumen configured to receive at least one of an implant and/or a dilator, a first steerable actuator coupled to the shaft at a position on the shaft substantially corresponding to the annulus of the mitral valve when the distal end of the shaft is disposed within the left ventricle, and a handle assembly coupled to a proximal end of the shaft. The handle assembly may comprise a first actuator coupled to the first steerable actuator. The first actuator may be configured to apply a force to the first steerable actuator to deflect the shaft about a region proximate to the first steerable actuator.

  • Patent number: 8506623
    Abstract: An implant delivery system comprising a catheter including at least one lumen, an implant configured for receipt in the lumen, and a latching mechanism configured for receipt in the implant.
