A system for repairing a defect on an articular surface of a patient's trochlear region, the system comprising a guide block comprising a body having an exterior surface configured to engage with the saddle portion and ridge portions of the patient's trochlear region, a protrusion extending generally from the body and configured to be received in a first bore formed in the articular surface along a reference axis, and a first cavity extending through the body configured to establish a first working axis displaced from the reference axis, wherein the exterior surface of the body and the protrusion are configured to secure the location of the guide block about the patient's trochlear region. A method for preparing an implant site in bone, comprising: establishing a reference axis extending from the bone; creating a bore in the bone by reaming about the reference axis; securing a guide block about the articular surface; establishing a first working axis extending from the bone using the guide block, the first working axis is displaced from the reference axis; and creating a first socket in the bone by reaming about the first working axis, wherein the first socket partially overlaps with the bore.

An endovascular stent-graft is provided that includes a structural member, which includes structural stent elements, at least a portion of which define a stent body when the stent-graft assumes a radially-expanded state; and a fluid flow guide. When the stent-graft assumes the radially-expanded state, (a) a first subset of the structural stent elements are configured to cause the stent body and the fluid flow guide to define a bulge that extends radially outward and has a greatest cross-sectional area that is equal to at least 120% of a cross-sectional area of a narrowest portion of the stent-graft rostral to the bulge, and (b) a second subset of the structural stent elements are not configured to cause the fluid flow guide to define the bulge. The structural stent elements of the first subset at least partially overlap the structural stent elements of the second subset lengthwise along the stent body.

Some embodiments are directed to medical devices, and methods for making and using the medical devices. An exemplary medical device includes a first elongate member, a second elongate member, and a coupler. The coupler may be configured to removably couple the first elongate member to the second elongate member.

An elbow prosthesis includes a stem structure and an articulating component. The stem structure is operable to be positioned in a bone of a joint and includes a stem portion and a C-shaped body portion. The stem portion is operable to be positioned in the bone. The C-shaped body portion includes a first articulating surface bound by a medial wall and a lateral wall. The medial and lateral walls are separated by a first distance. The articulating component includes a second articulating surface positioned between a medial side surface and a lateral side surface. The medial and lateral side surfaces are separated by a second distance that is less than the first distance. The second articulating surface is configured to slidably communicate in a medial/lateral direction along the first articulating surface of the C-shaped body portion.

Various embodiments of craniofacial implants, surgical instruments, and techniques are described to provide improved surgical results.

A device comprising a corneal implant for implantation within the cornea, the implant defining a planar body comprising: (i) an inner platform portion located about an axis of circular symmetry of the implant, (ii) a peripheral portion comprising one or more angularly-spaced arms that extend laterally from a peripheral edge of the inner platform, and (iii) a peripheral skirt portion which defines an outer circular perimeter of the implant, wherein the one or more angularly-spaced arms connect between the inner platform and the peripheral skirt portion; a wireless communication circuit configured for receiving an image data signal from an extraocular unit; an image projection controller configured to process the received image data signal to generate an image; and an image generator mounted to the inner platform portion, configured to project an image projection light beam, based on the generated image, in a posterior direction onto the retina of the eye.

A visceral double-barreled main body stent graft and methods for its use, the stent graft comprises, a main body stent graft having distal and proximal ends, the main body stent graft's length ranges from about 100-120 mm and diameter at the proximal end ranges from about 30-45 mm, first and second lumens defined at the main body stent graft's distal end, the first lumen's diameter ranges from about 18-20 mm, the second lumen's diameter ranges from about 16-18 mm, the first and second lumens have about the same length from about 50-70 mm, the first lumen is secured to the second lumen along a shared length, and the main body stent graft defines a tubular wall that is contiguous with the first and second lumens such that any fluid entering the main body must exit through one of the first or second lumens.

An implant system for total shoulder arthroplasties, hemi shoulder arthroplasties, and reverse total shoulder arthroplasties including a humeral stem having an enlarged head portion with interfaces adapted to removably receive various modular interchangeable components, such as articulating liners, spacers, and adapter inserts. The humeral stem functions as a universal platform that may be used in either conventional or reverse total shoulder arthroplasties, as well as hemi shoulder arthroplasties, and may remain implanted in place during a revision in which the implant system is converted between the foregoing configurations, for example.

An endoluminal device can be configured for precise positioning during deployment within a vessel. The endoluminal device can be a tack, stent, vascular implant or other type of implant. The endoluminal device can have circumferential member with an undulating configuration having multiple inward and outward apexes and struts extending therebetween. Two of the struts can be used to establish a foot for the precise positioning of the device during deployment. A method of placing the endoluminal device can include withdrawing an outer sheath such that a portion of the endoluminal device is expanded prior to the rest of the endoluminal device.

A prosthetic heart valve may include a stent body with a plurality of cells arranged in circumferential rows and a cuff attached to the stent. A leaflet attachment panel may be attached to and span a portion of one of the cells. A prosthetic valve element, such as a leaflet having a belly, may be mounted to the leaflet attachment panel. The leaflet attachment panel may not be integral with the stent body. A reduced overlap area may be defined between a proximal end of the stent body and a proximalmost point of attachment of the leaflet belly to the cuff. The reduced overlap area may have a size dependent upon the circumferential row of cells the leaflet attachment panel is attached to and a position of the portion of the leaflet attachment panel to which the leaflet is mounted. Alternately, the leaflet may be attached directly to the stent.
