Implants for altering wear patterns of articular surfaces
Methods and devices for correcting wear pattern defects in joints. The methods and devices described herein allow for the restoration of correcting abnormal biomechanical loading conditions in a joint brought on by wear pattern defects, and also can, in embodiments, permit correction of proper kinematic movement.
RETENTION DEVICES, LATTICES AND RELATED SYSTEMS AND METHODS
A woven retention device, lattice device and woven patch device that are configured to receive a fastener in a bone hole can be configured to impede biofilm formation. The devices can be made of woven filaments that outline apertures of varying sizes and shapes and can serve as an interface between a fastener and the bone material. The devices can be configured to allow for optimal bone growth while at the same time minimizing the likelihood that biofilm forms thereon. The devices can be made of materials that facilitate soft tissue fixation, and screw-activated expansion.
Medical devices for use along the biliary and/or pancreatic tract
Medical devices and method for making and using the same are disclosed. An example medical device may include implantable medical device for use along the biliary and/or pancreatic tract. The implantable medical device may include a tubular member having a first end configured to be disposed within the duodenum of a patient and a second end configured to be disposed adjacent to a pancreatic duct and/or bile duct. The tubular member may have a body including one or more wire filaments that are woven together. The tubular member may also have an outer surface with a longitudinal channel formed therein.
WRIST PROSTHESIS, AND A SET OF COMPONENTS FOR FORMING THE SAME
The invention relates to a wrist prosthesis (1), comprising a proximal prosthesis body (21) and a distal prosthesis body (11), wherein, at least in a deployed state of the wrist prosthesis, a portion of the proximal prosthesis body that faces away from the distal prosthesis body is provided with a convexly curved surface (22). Additionally, a portion of the distal prosthesis body that faces away from the proximal prosthesis body is furthermore provided with a convexly curved surface (12). Furthermore, the surfaces of the proximal prosthesis body and the distal prosthesis body that are facing each other are provided with complementary convex-concave curved surfaces (13, 23). The invention further relates to a set of components for such a wrist prosthesis, which allows the wrist prosthesis to be placed in a wrist, without anchoring means, and with a high degree of adaptation to the specific situation.
Devices for therapeutic vascular procedures
Devices for treating a cerebral aneurysm may include proximal and distal self-expanding resilient permeable shells each including a plurality of elongate resilient filaments having a braided structure. The distal permeable shell may include a first plurality of filaments gathered at least at the proximal end thereof. The proximal permeable shell may include a second plurality of filaments are gathered at least at the proximal end thereof. The expanded state of the distal permeable shell may have a convex shape at the distal end of the distal permeable shell and the expanded state of the proximal permeable shell may have a generally convex shape at the proximal end of the proximal permeable shell. The expanded states of the distal and proximal permeable shells may also define a toroidal cavity through which an elongate support member extends.
STENT
The invention relates to a stent having a tubular woven structure (3) formed from wire strands (1, 2) interwoven with one another, wherein at least one first wire strand (1) is formed by at least two individual wires (1.1, 1.2) which run adjacently and contact one another, wherein the first wire strand (1) winds helically in a first direction around an axis of rotation of the woven structure (3) and crosses at least one second wire strand (2), which comprises at least one individual wire (2.1) and winds helically in a second direction around the axis of rotation of the woven structure (3), and wherein at least one individual wire (1.1) of the first wire strand (1) comprises an X-ray visible core material which is encased by a sheath material having a lower X-ray visibility than the core material.

The device includes an expandable cylindrical structure made of wires and a self-expanding permeable shell located at the distal end of the cylindrical structure. Methods and devices for treating a cerebral aneurysm are described. The device may include a distal self-expanding resilient permeable shell, a proximal self-expanding resilient permeable shell, and an elongate support member positioned between the distal and proximal permeable shells. The elongate support member may be rigid or may be a coil, such as an extension spring. The distal and proximal permeable shells may be made from a plurality of braided filaments, the shells having different pore sizes. The device may also be a braided implant with a force biasing component, such as a coil or generally circular extension, attached to its distal end.
Stents having radiopaque mesh
A stent including a mesh made of strands. The mesh has at least one radiopaque strand and at least one non-radiopaque strand, and the at least one radiopaque strand and the at least one non-radiopaque strand each have different diameters. Each strand has an index of wire stiffness EI, where EI is the mathematical product of the Young's modulus (E) and the second moment of area (I). The EI of all strands in the mesh is no more than five times the EI of the strand having the smallest EI of any of the strands.
IVC FILTER WITH TRANSLATING HOOKS
A filter with translating hooks is described. The filter can include strut members having first and second struts connected by a connecting portion, A translating hook is disposed adjacent the connecting portion at the strut members, the hook including a first elongate member attached at one end to the first strut and a second elongate member attached at one end to a second strut, the opposite ends of the elongate members connected together to define a tip. The translating hooks are configured to bend toward a central axis of the filter when the filter is in a collapsed configuration for delivery to a blood vessel and recovery from a blood vessel, and away from the central axis of the filter when the filter is in an expanded configuration within a blood vessel such that the hooks engage a vessel wall.
