Abstract: Disclosed is a tubular endoluminal vascular prosthesis, useful in treating, for example, an abdominal aortic aneurysm. The prosthesis comprises a self expandable wire support structure surrounded by a flexible tubular membrane. A delivery catheter and methods are also disclosed.

Abstract: Disclosed is a low profile catheter shaft configuration for incorporation into any of a variety of catheters. The shaft comprises first and second side-by-side lumens with a movable wall extending axially therebetween. The first lumen may occupy more than half of the inside diameter of the shaft such as during advancement along a guidewire, and the second lumen may occupy more than half of the inside diameter such as following withdrawal of the guidewire and during inflation of a balloon. Methods are also disclosed.

Abstract: Disclosed is a femoral neck fracture fixation device, for reducing and compressing fractures in the proximal femur. The fixation device includes an elongate body with a helical cancellous bone anchor on a distal end. An axially moveable proximal anchor is carried by the proximal end of the fixation device. The device is rotated into position across the femoral neck and into the femoral head, and the proximal anchor is distally advanced to lock the device into place.

Abstract: Disclosed is a bone fracture fixation device, such as for reducing and compressing fractures in the proximal femur. The fixation device includes an elongate body with a helical cancellous bone anchor on a distal end. An axially moveable proximal anchor is carried by the proximal end of the fixation device. The device is rotated into position across the fracture or separation between adjacent bones and into the adjacent bone or bone fragment, and the proximal anchor is distally advanced to apply secondary compression and lock the device into place. The device may also be used for soft tissue attachments.

Abstract: Disclosed is a fracture fixation device, for reducing and compressing fractures in a bone. The fixation device includes an elongate body comprising a first portion and a second portion that are detachably coupled to each other. The first portion defines a helical cancellous bone anchor and the second portion defines a distal end. An axially moveable proximal anchor is carried by the proximal end of the fixation device and is rotationally locked to the first portion. The device is rotated into position across the femoral neck and into the femoral head, and the proximal anchor is distally advanced to lock the device into place. The second portion is then detached from the first portion.

Abstract: Disclosed is a bone fixation device of the type useful for connecting soft tissue or tendon to bone or for connecting two or more bones or bone fragments together. The device comprises an elongate body having a distal anchor thereon. A proximal anchor is axially movably disposed with respect to the distal anchor, to accommodate different bone dimensions and permit appropriate tensioning of the fixation device. In one embodiment, the fixation device is optimized for construction from a biocompatible metal such as titanium, and the proximal anchor is removable to permit removal of the fixation device.

Abstract: Disclosed is a closed lumen catheter for facilitating placement of a radiation source within a vessel. A distal portion of at least a first lumen and a second lumen are separated by a moveable wall, allowing a reduced catheter shaft profile. Centering structures, such as one or more inflatable balloons, with perfusion, may be added. Methods are also disclosed.

Abstract: Disclosed is a self-expandable prosthetic venous valve, such as for implantation in the deep veins of the leg. The valve is mounted in a support structure, such as a self-expandable tubular wire cage. Deployment catheters and methods are also disclosed.

Abstract: Disclosed is a delivery catheter adapted for delivery of a dose of radiation to a vessel wall. A radiation source is enlargeable from a first, reduced cross-sectional profile to a second, enlarged cross-sectional profile by unwinding around a central core. Following delivery of a radiation dose to the vessel wall, the source is reduced in profile by wrapping around the core and removed from the treatment site.

Abstract: Disclosed is a low profile catheter shaft configuration for incorporation into any of a variety of catheters. The shaft comprises an inner collapsible tube coaxially disposed within an outer tube. The outer tube may be collapsible or relatively noncollapsible. The effect of the structure is to provide first and second side-by-side lumens with a movable wall extending axially therebetween. The first lumen may occupy more than half of the inside diameter of the shaft such as during advancement along a guidewire, and the second lumen may occupy more than half of the inside diameter such as following withdrawal of the guidewire and during inflation of a balloon. Methods are also disclosed.
