  • Patent number: 12251303
    Abstract: An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid reservoir. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. The fluid reservoir comprises a bellows region with one or more folds of the bellows extending circumferentially around an optical axis of the eye. The bellows engages the lens capsule, and a compliant fold region between the inner and outer bellows portions allows the profile of the AIOL to deflect when the eye accommodates for near vision. Fluid transfers between the inner fluid chamber and the outer fluid reservoir to provide optical power changes when the eye accommodates.

  • Patent number: 12208008
    Abstract: A valve fixation device may comprise a unitary elongate member that is biased towards a closed configuration wherein at least a pair of tissue engaging surfaces of the elongate member are held adjacent to each other by a bias force. The bias force is at least equal to a valve leaflet grasping force, enabling the fixation device to grasp and retain leaflets as part of cardiac treatment. A delivery tool including a spreader may independently translate the tissue engaging surfaces to enable cardiac leaflets to be captured and retained by and/or between the tissue engaging surfaces. The valve fixation device may include at least two arms, each of which may be independently controlled to grasp and capture opposing leaflets of a valve, such as the anterior and posterior leaflets of a mitral valve, to reduce the size of the valve opening and improve cardiac performance.

  • Patent number: 12138168
    Abstract: An annuloplasty implant comprises a flexible member, helical anchors, and non-compressible portions. The helical anchors are configured to anchor the flexible member at least partway around the valve by being screwed into tissue of the heart of a subject. Each of the non-compressible portions comprises a helical coil having a plurality of turns, and at rest has a helix pitch that contacts each turn of the coil with an adjacent turn of the coil. The flexible member extends through the non-compressible portions. The implant is configured such that applying tension to the flexible member from one end thereof contracts the implant, thereby drawing the anchors closer to each other, the helical coil of each of the non-compressible portions inhibiting contraction of the implant at the non-compressible portion.

  • Patent number: 12042243
    Abstract: Minimally invasive surgical techniques are used to obtain access to vertebrae while protecting soft tissues in the surrounding area. The dilators may be used to provide a working channel through which the operation is performed. Standard dilators may be used with a robotic surgical system to provide precise guidance of surgical tools. A dilator may be held by the robot and automatically repositioned when the surgeon adjusts a trajectory for performing the surgery. The dilator itself may be used as a surgical instrument guide along with dilator adaptors that adjust the diameter of a portion of the dilator to allow for different sized tools to be guided by the dilator. Alternatively, surgical instrument guides may also be held by the robotic arm such that tools are guided by a surgical instrument guide through the dilator to perform a medical procedure.
