  • Patent number: 10039635
    Abstract: An intraocular lens includes an optic, which includes a first lens having a first optical axis for alignment with an optical axis of the human eye having a macula; and a second lens having a second optical axis. The second optical axis and the first optical axis enclose an angle between 0.5 and 10 degrees. The first and second lens are arranged next to one another in a direction transverse to the first optical axis to provide no overlap in a direction along the first optical axis such that the first lens and the second lens each, independent from one another, image onto the macula of the eye. The angle and a direction of the second optical axis are chosen such that the second lens images onto a functional part of the macula of the human eye, which functional part is not compromised by a defect, such as a scotoma.

  • Patent number: 10039648
    Abstract: An intervertebral implant system installable between a pair of vertebrae. The implant includes a spacer that fits between the pair of vertebrae with a screw aperture for passage of a first screw and angled to orient the first screw into a first vertebrae at an angle relative to the rear sidewall of the spacer so that the first screw will enter an endplate of the first vertebrae. A plate is installable onto the rear sidewall of the polymeric spacer. The plate includes an angled screw aperture that is aligned with the screw aperture of the spacer when the plate is installed on the spacer. An elevated screw support extends upwardly or downwardly from the plate so as to extend opposite the direction of the angled screw aperture. The elevated screw support locates a second screw to enter a second vertebrae through an anterior surface of the second vertebrae.

  • Patent number: 9987126
    Abstract: An intraocular lens includes a deformable outer shell having a distal end and a proximal end, a fluid optic having at least one elastic membrane surface positioned to traverse an optical axis of a patient's eye and at least partially defining an internal chamber to hold an optical fluid, and an inner shell associated with the fluid optic having a distal end and a proximal end.

  • Patent number: 9962166
    Abstract: This invention is the method of treating an ailment associated with the cervical portion of the spine by performing an intravertebral corpectomy that includes the steps of removing the vertebral corpus to define a working channel for the surgeon to gain access to the epidural space so as to attend to and perform a procedure on the pathology. This method obviates the problems incidental to more radical cervical spine operations such as discectomy or corpectomy which requires removal of a portion of the vertebra and adjacent intervertebral discs for decompression of the cervical spinal cord and spinal nerves and using a bone graft with or without a metal plate and screws to reconstruct the spine and provide stability. Prior to terminating the surgery, the opening formed by the removed vertebral corpus is fitted and/or filled with a suitable implant.

  • Patent number: 9907644
    Abstract: A medical product comprises a biodegradable filament and a non-biodegradeable coating. The biodegradable filament forms a stent body having a first end portion, a middle portion, and a second end portion opposite the first end portion. The middle portion extends between the first and second end portions. The non-biodegradeable coating encapsulates the at least one biodegradable filament along the middle portion of the stent body. The non-biodegradeable coating forms a barrier such that the non-biodegradeable coating prevents degradation of the at least one biodegradable filament along the middle portion. The first and second end portions are uncoated. After implantation, the end portions of the stent may biodegrade. The middle portion will not biodegrade due to its encapsulation by the non-biodegradeable coating.
