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.

An absorbable vascular filter is disclosed for deployment within a vessel for temporary filtering of body fluids. A preferred embodiment is the placement of such absorbable vascular filter within the inferior vena cava (IVC) to filter emboli for the prevention of pulmonary embolism for a limited duration in time. Once protection from PE is complete, the filter is sequentially biodegraded according to a planned schedule determined by the absorption properties of the filter components. Hence the temporary absorbable vascular filter obviates the long term complications of permanent IVC filters such as increased deep vein thrombosis, while also circumventing the removal requirement of metal retrievable IVC filters.

A blood filter delivery system for delivering a filter into a vein from either a femoral or jugular access. The preferred system includes an introducer and a push-rod with a spline member disposed along the push-rod and a pusher member disposed on a distal end. The spline member has a main body, first and second boss portions spaced apart along the longitudinal axis to provide a gap for retaining anchor members of the filter during delivery via the introducer. In an alternative embodiment, a preferred filter includes first and second filter structures diverging in opposite directions. A link is connected to portions of each of the first and second filter structures so that each filter structure can be independently collapsed into a generally cylindrical shape.

Methods and devices for treating a cerebral aneurysm are described. The device may include a self-expanding resilient permeable shell made from elongate resilient filaments. At least some of the filaments have a distal region that extends beyond the distal end of the permeable shell and form an extension having a generally circular shape when expanded. The permeable shell has a radially constrained elongated state configured for delivery within a microcatheter and has an expanded state with a globular, axially shortened configuration. The permeable shell has a plurality of openings formed between the braided filaments. The distal regions of the plurality of filaments that form the extension may be braided, partially braided, or unraveled. Once deployed within the cerebral aneurysm, the extension is positioned near a dome of the cerebral aneurysm.

A problem with total disc implant surgery appears to be the positioning of the implant which if not correct may lead to pain and eventually new surgery. The present invention relates to an improved disc implant for total disc replacement, that includes two inter-vertebral elements which are flexibly connected via a coupling mechanism. Following surgery, the relative movability of the two inter-vertebral elements is decreased overtime, as bone ingrowth occurring around the implant and specifically through osseointegrative sections gradually decrease the movability of the elements relative to each other. Following, the relative movability of the implant elements is replaced by fixation of the elements. The fixation has flowingly occurred in a position affected by the movement of the patient, and is thereby more acceptable to the patient.

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 of 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.

The present invention is directed to a surgical implant for the fusion of two adjacent vertebrae with an upper plane for contacting an upper vertebral body and a lower plane for contacting a lower vertebral body and a tubular structure, wherein the tubular structure is formed by a plurality of tubes running from the upper plane to the lower plane and in substantially horizontal direction throughout one side of the surgical implant straight to the opposite side of the surgical implant. This tubular structure has the advantage that the formation and ingrowth of new bone is promoted and advantaged and that the degree of formation and ingrowth of new bone is detectable by X-ray measurements.

Disclosed herein are methods and devices for repairing a knee joint, including customizable and/or highly selectable implants and/or implant components for each patient to provide optimal fit and function.
