Described here are delivery devices for delivering one or more implants to the body, and methods of using. The delivery devices may deliver implants to a variety of locations within the body, for a number of different uses. In some variations, the delivery devices have a cannula with one or more curved sections. In some variations, a pusher may be used to release one or more implants from the cannula. In some variations, one or more of the released implants may be a self-expanding device. Methods of delivering implants to one or more sinus cavities are also described here.

A disposable device for treating a condition of a ureter or kidney having a cylindrical body about 1-2 mm in diameter by about 5 to 10 mm in length and having a top and bottom end. The body is made of absorbent material that expands upon contact with pharmaceutical agent and bodily fluids and includes a string connected to the bottom end of the body for removing the device. The device can be used to treat a condition of the ureter or kidney by inserting into the ureter or kidney, delivering a pharmaceutical agent, and removing the device after it has been impregnated with fluid. The device can be included in a kit with an insertion device and/or appropriate pharmaceutical agents.

Disclosed herein are methods of producing a cartilaginous implant by producing a polymer scaffold composition by electrospinning a polymer solution onto a collector in order to obtain polymer fibers; crosslinking the polymer fibers; and adding a plurality of cells to the polymer scaffold composition, wherein the plurality of cells comprises cartilaginous cells to form a cartilaginous implant.

Multi-filament microcables are used in place of the traditional monofilament wires as the constituent elements of a woven or braided band. This enhances the function and manufacturability of such bands for various applications, such as orthopaedic applications including sternotomy closures.

Medical stent designs are disclosed. An example stent includes a tubular scaffold having a proximal end and a distal end. The tubular scaffold includes a first filament extending between the proximal end and the distal end, the first filament including a first biodegradable region positioned adjacent to a second biodegradable region. Further, the first biodegradable region includes a first biodegradable material, the first biodegradable material having a first rate of degradation. The second biodegradable region includes a second biodegradable material, the second biodegradable material having a second rate of degradation, wherein the first rate of degradation is different from the second rate of degradation.

The present disclosure relates to valve replacement devices that are foldable for catheter-based deployment to the site of implantation, as well as systems for the delivery of valve prostheses, including prostheses having the special characteristics of the disclosed valve replacement devices. The devices include highly effective adhering mechanisms for secure and enduring precision implantation. The adhering mechanisms may employ a unique sealing mechanism that includes a cuff that expands slowly whereby the device is not secured in place until the completion of the implantation procedure. The implanted device, optionally together with the cuff, prevents perivalvular leaks and incorporate an appropriate leaflet system for reliable functioning in situ.

A stent system is disclosed. The stent system includes a balloon catheter having a balloon with a proximal zone, a transition zone and a distal zone including progressively decreasing diameters respectively. The stent of a pre-defined length includes a main branch segment, a transition segment and a side branch segment. The stent includes an expanded state and a crimped state. The stent is mounted over the balloon in the crimped state such that the main branch segment is mounted over the proximal zone, the transition segment is mounted over the transition zone and the side branch segment is mounted over the distal zone. In expanded state, the main branch segment, the transition segment and the side branch segment of the stent correspond to the respective zones of the balloon. The transition segment includes plural rows of elongated members connected to each other.

Systems and methods for tissue engineered synthetic support structures, such as grafts and patches are provided. The systems and methods can be used to make tissue engineered planar sheathes or meshes that can be fashioned into substantially planar or non-planar 3D tissue/organ structures adaptable to structure and organs within a human or mammalian body. The systems and methods can use bioink deposited on a material having specified properties and matured under specified conditions to create the tissue engineered planar sheathes or meshes having biomechanical and biological properties tailored to a particular tissue.

The invention is a modular interbody fusion device for fusing adjacent spinal vertebrae that is adapted to be implanted in a prepared interbody space including a first modular segment having a width including a first rail extending at least partially along one side of the width and beyond a periphery of a body portion of the first modular segment, a second modular segment having a width and slidably connected to the first rail on one side of the width and having a second rail extending at least partially along another side of the width and beyond a periphery of a body portion of the second modular segment, a third modular segment having a width and slidably connected to the second rail on one side of the width and wherein the device has an expanded position in which the second and third modular segments are extended along the first and second rails and positioned in a generally end to end configuration spaced apart by the rails prior to implantation and an implanted position in which the modular segments are positioned in a generally side by side configuration that defines a unitary body that mimics the planar shape of the vertebra such that the device contacts and supports the adjacent vertebra.

Treating a treatment area in the vasculature includes a first catheter adapted for positioning at the treatment area, said first catheter including a first balloon having a transient radiopaque material corresponding to the treatment area. A second catheter adapted for positioning at a treatment area includes a treatment that substantially matches the transient radiopaque material, preferably so that the length and/or position of the treatment corresponds to the length and/or position of the transient radiopaque material. Related kits, assemblies, and methods are also described.
