Abstract: A prosthetic remodeling annuloplasty ring for use in tricuspid or mitral valve repairs to provide support after annuloplasty surgery. The annuloplasty ring includes a relatively rigid core extending around an axis that is discontinuous to define two free ends. A suture-permeable interface surrounding the core includes floppy regions adjacent both free ends of the core. Sutures are used to attach the annuloplasty ring to the annulus, including at least one suture through each of the floppy regions to secure the free ends of the ring and minimize the risk of ring dehiscence, or pull through of the sutures through the annulus tissue. The floppy regions may project from each free end into the gap toward each other, be radially enlarged such as paddle-like extensions, or may comprise outwardly lateral extensions at the free ends of the core.

Abstract: An elbow prosthesis constructed in accordance to one example of the present teachings can include a first stem structure that is operable to be positioned in a first bone of a joint. The first stem structure can include a first stem portion and a cage structure. The first stem portion may be operable to be positioned in the first bone. The cage structure can be formed generally between an inner sidewall and an outer surface. The stem portion can have opposing surfaces that define a disconnect formed entirely through the cage structure from the inner sidewall to the outer surface. A first bearing component can have an exterior cage opposing surface. The first bearing component can be selectively inserted into the cage structure from an insertion position to an installed position. A fastener can be threadably advanced into an engaged position with the cage structure to reduce a gap defined between the opposing surfaces of the disconnect while radially contracting the cage structure around the first bearing.

Abstract: Prosthetic and/or orthotic devices (PODS), control systems for PODS and methods for controlling PODS are provided. As part of the control system, an inference layer collects data regarding a vertical and horizontal displacement of the POD, as well as an angle of the POD with respect to gravity during a gait cycle of a user of the POD. A processor analyzes the data collected to determine a locomotion activity of the user and selects one or more control parameters based on the locomotion activity. The inference layer may be situated between a reactive layer control module and a learning layer control module of the control system architecture.

Abstract: A prosthetic tricuspid remodeling annuloplasty ring for use in tricuspid valve repairs to provide annular support after reconstructive valve surgery. The ring maintains an optimal annular dimension to prevent excessive dilatation of the natural valve annulus while adapting to the dynamic motion of the tricuspid annulus during the cardiac cycle. An exemplary ring features a waveform contour and may be constructed of a titanium core having a varying cross-section for selective flexibility for good Z-axis or out-of plane movement. The “waveform” contour and selective flexibility of the different segments of this ring are designed to adapt to the complex motion of the annulus. This reduces the stress on the anatomical structures and therefore minimizes the risk of arrhythmia and ring dehiscence.

Abstract: Embodiments of the invention provide knee prostheses which more faithfully and closely replicate the function, anatomy and physiology of the normal human knee yielding a number of advantages. Among other things, such prostheses can provide an increased range of motion and function more normally particularly in extension, deep flexion and during normal gait. Knee prostheses according to various aspects of the invention recognize that during movement of the knee, particularly during flexion, the kinematics of the bones of the knee are a result of achieving equilibrium of the forces that cause motion of the knee. In addition, the shape of the articular surfaces acting in combination with forces imposed by various muscles, ligaments and tendons, determines the direction of the large contact forces.

Abstract: A medical treatment system and method of treatment is described having an implant that can be positioned and deployed, then undeployed to allow repositioning of the implant. The system includes a self-expanding medical implant that longitudinally foreshortens upon radially expanding from a radially compacted state, a distal interface configured to attach the implant to a distal mount of a delivery device, and a proximal interface configured to attach the implant to a proximal mount of the delivery device. Moving the distal mount longitudinally away from the proximal mount applies a longitudinal tension to the implant causing the implant to expand longitudinally and contract radially, and moving the distal mount toward the proximal mount reduces a longitudinal tension in the implant allowing the implant to expand radially toward a fully expanded state.
