An intraocular lens comprises a lens body customized for astigmatism in a particular eye. For the customization to work, the astigmatism in the lens has to be aligned with astigmatism in the eye. Thus the intraocular lens comprises four protrusions arranged outwardly around the lens body to form the four corners of a substantially rectangular profile. The profile locks the intraocular lens into a position of rotational stability when inserted into a capsular bag, thus preventing rotation of the intraocular lens, which would otherwise tend to occur both immediately after insertion into the capsular bag and later on during growth, shrinkage or other change to the capsular bag. The Intraocular lens may additionally be customized for other eye conditions and a multi-focal embodiment is also disclosed.

Methods and devices are adapted for implanting into the eye. An incision is formed in the cornea of the eye and a shunt is inserted through the incision into the anterior chamber of the eye. The shunt includes a fluid passageway. The shunt is passed along a pathway from the anterior chamber through the scleral spur of the eye into the suprachoroidal space and positioned in a first position such that a first portion of the fluid passageway communicates with the anterior chamber and a second portion of the fluid passageway communicates with the suprachoroidal space to provide a fluid passageway between the suprachoroidal space and the anterior chamber.

A dynamic, adjustable annuloplasty ring sizer can include an adjustable ring replica, which can be adjusted through a range of sizes corresponding to available prosthetic annuloplasty repair ring sizes. Actuation of an adjustment trigger on a handle portion of the ring sizer can displace tension wires that extend through a malleable shaft and through a plurality of articulating segments that form the ring replica. Displacement of the tension wires causes flexion of the joints between adjacent articulating segments, thereby reducing the overall size of the ring replica. Releasing the tension wires can allow an elastic extension wire to act on the ring replica, enlarging the ring replica to its maximum, at-rest size. In this manner, the appropriate size of annuloplasty ring prosthesis can be determined with a single device, without requiring a plurality of static ring sizers that require individual insertion and placement for the conventional trial-and-error sizing methods.

Novel stay suture devices and stay suture combinations with meshes are disclosed. The stay suture devices have a clip and a suture. The clip has leg members that are mounted to a hernia mesh implant such that the leg members are locked in a closed configuration. Also disclosed are novel methods of mounting stay sutures to a surgical mesh implant and repairing a body wall defect such as a hernia defect.

A tissue expansion device can be implanted temporarily beneath skin of a patient and removed upon expansion of overlying tissue. The device can include an expandable shell having a smooth or glossy outer surface and an injection port. The expandable shell can form an expandable chamber and have an anterior portion and a posterior portion. The injection port can be coupled to the anterior portion of the shell and be in fluid communication with the chamber and configured to permit injection of fluid into the chamber from a hypodermic needle. The device can have a plurality of tabs coupled to the posterior portion of the shell having one or more colors or attributes. The device can also include an orientation indicator visible along the anterior portion of the shell for assisting a clinician and orienting the device during the implantation procedure.

Apparatus and methods are provided for treating urinary incontinence, fecal incontinence, and other pelvic defects or dysfunctions, in both males and females, using one or more lateral implants to reinforce the supportive tissue of the urethra. The implants can be configured as a sling device having at least one extension arm and a tissue support portion having an eyelet, wherein a portion of the at least one extension arm is adapted to slide through and adjustably attach with the eyelet.

The embodiments disclosed herein include improved toric lenses and other ophthalmic apparatuses (including, for example, contact lens, intraocular lenses (IOLs), and the like) that includes one or more refractive angularly-varying phase members, each varying depths of focus of the apparatus so as to provide an extended tolerance to misalignments of the apparatus. Each refractive angularly-varying phase member has a center at a first meridian (e.g., the intended correction meridian) that directs light to a first point of focus (e.g., at the retina of the eye). At angular positions nearby to the first meridian, the refractive angularly-varying phase member directs light to points of focus of varying depths and nearby to the first point of focus such that rotational offsets of the multi-zonal lens body from the center of the first meridian directs light from the nearby points of focus to the first point of focus.

Embodiments for a Mooreville Needle Introducer, and methods for using and making the same are disclosed. The Mooreville Needle Introducer can be constructed of a first part and a second part that can be joined together to form an enclosure for receiving a pusher. The first part and the second part can also be formed with pairs of complementing adapters that fasten together for secure alignment. The first part can be detached from the second part by applying force to a set of handles. When the first part and the second part are detached, they can be effectively cleansed and sterilized, eliminating any lingering bacteria.

The embodiments provide a spinal implant that is configured for midline insertion into a patient's intervertebral disc space. The spinal implant may have a body and the body comprises one or more apertures. The apertures receive fixation elements, such as a screw and the like. The fixation element may comprise one or more anti-backout features, such as a split ring. In addition, at least some of the apertures are designed to permit a predetermined amount of nutation by a fixation element. The apertures that allow nutation enable the fixation element to toggle from one position to another, for example, during subsidence of the implant in situ. Some of the apertures may be configured to rigidly lock with the fixation elements. Moreover, the spinal implant may include features, such as one or more bores, that can accommodate imaging marks to help guide a surgeon.

An implantable medical device and surgical instrument for use during a procedure for treatment of vaginal vault prolapse. The invention also includes an instrument which allows the pieces of the suspension material to be attached to each other and enables the appropriate suspension of the vaginal apex from the anterior part of the sacrum. The device and method permit the performance of a sacrocolpopexy by accessing the sacrum and vaginal tissues via the vaginal orifice, thus avoiding the abdominal cavity completely.
