Abstract:
An embolic protection device for capturing emboli during treatment of a stenotic lesion in a body vessel is disclosed. In one example, the device comprises a filter and a filter portion made of an extracellular matrix circumferentially attached to the filter. The filter comprises a plurality of struts having first ends attached together at a center portion along a longitudinal axis. Each strut has an arcuate segment extending from the first end to a second end. The struts are configured to move between an expanded state for engaging with the body vessel and a collapsed state for filter retrieval or delivery. The filter portion is configured for allowing blood to flow therethrough and for capturing emboli when the filter is in the expanded state.
Abstract:
A coated medical device adapted for introduction into a passage or vessel of a patient is provided. The medical device is preferably an implantable balloon with a bioactive deposited or within the balloon. The balloon can further include a hydrophilic material positioned between the balloon and a bioactive material posited on the balloon.
Abstract:
An apparatus is provided for introducing a wire guide into a vessel through a medical device. The apparatus generally includes a body, a distal tip, and a first advancement wheel. The body defines a first axial passageway therein. The distal tip of the body defines a male Luer fitting and terminates in a taper having an angle relative to an outer surface of the male Luer fitting. The advancement wheel is rotatably attached to the body and positioned adjacent the first axial passageway. The first wheel defines a grasping area contacting the wire guide and axially translates the wire guide relative to the body. A holder is preferably attached to a proximal end of the body and stores a portion of the guide wire for delivery into the vessel.
Abstract:
A stent is provided which can be crimped to a reduced profile with reduced stress in the stent, while maintaining the strength and flexibility of the stent so that it can be advanced through the narrow passageways present in a patient's body and then expanded to dilate and/or circumferentially support the vessel wall. Also provided is a method of deploying such a stent.
Abstract:
An electropolishing apparatus and method are provided for polishing stents and other medical implants. The apparatus includes a motor that rotates a roller. The roller continuously rotates the medical implant to be electropolished. One of the advantages of the apparatus and method is that marks generated around the electrical contact between the anode and the medical implant are minimized. In addition, the medical implant is polished more evenly than conventional electropolishing systems.
Abstract:
Medical devices, methods and kits useful in the disruption and removal of unwanted materials, such as calculi and other formations, from within body lumens are described. The disclosure describes particular embodiments and methods useful in the lithotriptic removal of stones from the salivary glands.
Abstract:
Devices, kits, and methods of treatment are described. More particularly, methods of treating tissue of a passage wall defining a bodily passage, such as a sinus cavity, airway, or sinus passage are described. An exemplary method utilizes an elongate member having an elongate member proximal end, elongate member distal end, and an elongate member body that defines a curve.
Abstract:
Medical devices are described. More particularly, medical devices and methods for the identification and treatment of bodily passages, such as sinus cavities, are described herein. An exemplary medical device comprises an elongate member, a handle, and a wire member. The elongate member is moveable between a first straight, or substantially straight, configuration to a second curved configuration.
Abstract:
Catheters useful in the identification and treatment of bodily passages, such as sinus cavities, are provided. A catheter includes an elongate main body defining an inflation lumen and an optic lumen, an inflatable balloon attached to the distal end of the main body, and a fiber optic disposed in the optic lumen. When connected to a light source, the fiber optic emits light radially along a portion of the balloon and axially from the distal end of the main body. Methods of identifying and treating bodily passages, such as sinus cavities, are also described.
Abstract:
Delivery systems and methods of creating an accessory maxillary ostium and implanting a ventilation tube for purposes of ventilation, irrigation, infusion or procedural work are described. The delivery systems include an introducer and an associated ventilation tube. An irrigation and/or infusion catheter may be advanced through the ventilation tube in order to irrigate or express the contents of the sinus cavities. A secondary irrigation and/or infusion catheter or a balloon catheter may be advanced through an outer irrigation and/or infusion catheter, deeply into the sinus cavity, in order to irrigate or express the contents of the sinus cavities. Moreover, the balloon catheter may alternatively or additionally be employed to for dilation of the natural ostium. Still further, a device for delivering drugs, fluids or the like, may be coupled to the ventilation tube for delivery of same.
