According to one embodiment, a method comprising intraoperatively scanning a joint surface, processing the scan and creating a three-dimensional computer model, performing simulations with the three-dimensional computer model, determining an optimal implant attribute from analysis of the simulations, selecting an optimal implant, determining an ideal positioning and orientation of the selected implant relative to scanned anatomical features, rapidly creating a patient-matched guide to facilitate bone surface preparation in order to achieve ideal positioning and orientation of the selected implant, preparing the surface using the patient matched guide, and implanting the optimal implant is set forth.

Abstract: A prosthesis and a method for controlling flow through a bodily lumen in a first direction and a second direction are provided. The prosthesis includes a body having a proximal portion, a distal portion and a body lumen extending therethrough. The prosthesis also includes a first valve for controlling flow through the body lumen in a first direction where the first valve forms a first opening in the prosthesis. The prosthesis includes a second valve for controlling flow through the body lumen in a second direction where the second valve includes a portion that contacts the body in a closed configuration and the portion is spaced apart from the body in an open configuration to form the second opening. The first opening is positioned apart from the second opening and the second opening opens in response to a higher pressure than the first opening.

Abstract: An acetabular socket (1) for a hip endoprosthesis comprises a socket shell (7) and a socket insert (8). The socket shell (7) is configured for implantation in a pelvic bone (2) of a patient and has an inner surface (12) that defines an accommodating space (10) extending about an axis of rotation (11).

Abstract: Techniques and reconstruction systems for fixation of bone to bone, or soft tissue to bone, that allow a double-bundle type construct with only three tunnels, a single graft and individual tensioning in each of the three tunnels. Alternative double-bundle ACL/PCL fixation techniques are provided that employ a double-bundle type construct with only a single graft and three tunnels/sockets. The double-bundle ACL and PCL techniques and constructs allow individual tensioning of each of the bundles (e.g., tensioning of each of the anteromedial (AM) and posterolateral (PL) bundles of the ACL) and eliminate the need for additional fixation devices (for example, interference screws) to secure the bundles within the bone tunnels/sockets.

Abstract: A hip implant having two distinct bodies, a neck body and a bone fixation body. The neck body is formed from a solid metal and has an interface for connecting to a femoral ball. The bone fixation body has an elongated shape and is formed as a porous structure that is inserted into an intramedullary canal of a patient.

Abstract: A support structure includes strut members interconnected by rotatable joints to form a series of linked scissor mechanisms. The structure can be remotely actuated to compress or expand its shape by adjusting the scissor joints within a range of motion. In particular, the support structure can be repositioned within the body lumen or retrieved from the lumen. The support structure can be employed to introduce and support a prosthetic valve within a body lumen.

Abstract: In one embodiment, the instant invention is a method that includes at least providing a prosthesis that includes at least an implant capable of deformation under pressure; inserting the implant in a void space in a joint; inflating the implant by adding a first amount of a filler to the implant, where the first amount of the filler is X; articulating the joint; releasing a second amount of the filler from the implant through a pressure regulating valve based on a predetermined pressure in the implant, where the second amount of the filler released from the implant is Y; and sealing the implant, where X is greater than Y.

Abstract: A prosthetic joint is secured to the bones forming the original joint by utilizing strictly mechanical fasteners, for example, a threaded rod engaging a tapped intramedullary canal. Cross locking members may be provided. The need for bone cement is avoided. The prosthetic joint may be used to replace one end of one bone forming the joint, utilizing the naturally occurring end of the other bone. Alternatively, both bone ends may be replaced with prosthetic joint portions. The decision to replace one or both bone ends may be made mid-surgery. The prosthetic joint portions are secured together utilizing ligament reconstruction members made from portions of the patient's tendons or allograft tendons. A bearing forming the interface between the two joint portions is designed to wear in order to protect the remaining components from wear, and to be easily replaced in relatively simple future surgeries.

A height-adjustment mechanism of the insert is coupled to and positioned generally between the upper plate and the lower plate and is configured to move between a closed position where the upper and lower plates are adjacent each other and an opened position where the upper and lower plates are spaced-apart from each other in order to adjust a height or thickness of the insert.

Abstract: A hip implant having two distinct bodies, a neck body and a bone fixation body. The neck body is formed from a solid metal and has an interface for connecting to a femoral ball.

Abstract: A terminal soft tissue attachment and repair device has a sheet of mesh with two longitudinal sides and two lateral ends angled to the sides. One end has a smooth surface where the healing tissue rests and the sides mutually overlap. The device attains a frusto-conical shape of a proximal component and a distal component. The two sides and one end of the proximal component have suture holes. The other end of the proximal component merges with both sides and joins them to the distal component. From the joint, the two sides extend in a V shape spanned by laced suture. A surgeon places an end of tissue within the device. The surgeon then laces suture and then pulls it from one location to secure the invention upon the tissue and the distal component to a bony insertion. The invention attains a shape like the natural tissue.

Abstract: Ureteral stents include a tubular body defining a lumen and have a distal kidney section, a proximal bladder section, and a ureter section between the distal and proximal sections. The tubular body has a first material layer and a stiffening member that extends through at least a portion of a length of the tubular body. The stiffening member has a stiffness characteristic that varies along its length. This enables different portions of the stent to have different stiffness characteristics that preferably are optimized for the location of those portions within the human body. The stiffening member may be at least a second material layer having a second stiffness that is different from a first stiffness of the first material layer, and/or at least one strand of material that is embedded within the first material layer.

The reinforced construct preferably includes a stitched reinforced region formed by employing a suture loop construct with a free floating needle that is attached to the suture loop, and also with a piece of material (a reinforcement or reinforcing material) attached to the suture loop. The reinforced construct may be attached to any fixation device and/or any bone tunnel.

Abstract: A graft retention device has an elongated body with a first and second ends and a midpoint therebetween. A pair of elongated slots formed through the body defines a tang therebetween. A graft retention loop is disposed over the tang and is slidable therealong. A trailing line connects to the body adjacent the slots and extends therefrom through the graft retention loop toward the first end. Tension applied to the trailing line thus tends to urge the graft retention loop away from the first end and toward the midpoint.
