20100331817 | THERAPEUTIC AGENT DELIVERY DEVICE WITH A DUAL BALLOON HAVING DISTAL TAPER APERTURES - The present disclosure generally provides a multiple balloon assembly used as part of the distal region of a medical device that is capable of delivering a therapeutic agent into a body vessel having bodily fluid. The multiple balloon assembly comprises an inner balloon and an outer balloon. The outer balloon further comprises a proximal taper region, a middle region, and a distal taper region. The inflation of the inner balloon causes the middle region of the outer balloon to contact the inner wall of the body vessel, thereby, occluding the flow of fluid through the body vessel. The proximal taper region and the distal taper region are configured such that they do not touch the inner wall of the body vessel. One of the distal taper and proximal taper regions has a plurality of apertures configured to allow for the therapeutic agent to be delivered into the body vessel at a predetermined rate. A medical device that incorporates the multiple balloon assembly of the present disclosure, as well as a method for using the medical device and multiple balloon assembly are further disclosed. | 12-30-2010 |
20110153007 | Taxane Coatings for Implantable Medical Devices - This disclosure relates to implantable medical devices coated with a taxane therapeutic agent, such as paclitaxel, in one or more solid form(s) having varying dissolution rates. Particularly preferred coatings comprise amorphous and/or solvated solid forms of taxane therapeutic agents that provide durable coatings that release the taxane over a desired period of time, which can be varied in the absence of a polymer by selecting the type and amount of solid forms of the taxane therapeutic agent in the coating. Other preferred embodiments relate to methods of coating medical devices and methods of treatment. The coatings can provide a sustained release of the taxane therapeutic agent within a body vessel without containing a polymer to achieve the desired rate of paclitaxel elution. | 06-23-2011 |
20120010692 | GRAFT DEPLOYMENT ASSIST TOOL - A delivery system for a medical device may include a sheath, a catheter slideably disposed within the sheath, and a hemostatic device comprising a housing disposed around and sealingly engaged with the sheath by a first seal. A sleeve is slideably coupled to the catheter and comprises a second seal sealingly engaging the catheter. The sleeve is movable between a first position, in which the sleeve is disposed outside of the housing and the first seal is sealingly engaged with an outer surface of the catheter, and a second position in which at least a portion of the sleeve is disposed within the housing between an inner surface of the housing and the outer surface of the catheter, wherein, in the second position, the first seal is sealingly engaged with an outer surface of the sleeve and the second seal is sealingly engaged with the outer surface of the catheter. | 01-12-2012 |
20120141656 | NEEDLE-TO-NEEDLE ELECTROSPINNING - An electrospinning apparatus may include a first spinneret and a second spinneret, each including a reservoir and an orifice. The first and second spinnerets may have first and second electrical charges, respectively. The first spinneret orifice may be located substantially opposite the second spinneret orifice. The first and second spinnerets may be used to prepare a medical device defining a lumen with a proximal end, a distal end, a luminal surface and an abluminal surface. The first spinneret orifice distal end may be configured to be located outside of the medical device lumen and between about 0.1 inches and about 6.0 inches from the medical device abluminal surface. The second spinneret orifice distal end may be configured to be located in the medical device lumen and between about 0.1 inches and about 6.0 inches from the medical device luminal surface. | 06-07-2012 |
20120165850 | Spring Action Medical Device - A spring action medical device includes a spring that may propel a hammer component in a distal direction when the spring is released from a loaded state. When propelled forward by the spring, the hammer component makes contact with a distal tip of the medical device. The distal tip may then transfer a force to an external object, such as an occlusion in a body lumen. | 06-28-2012 |
20120172913 | DELIVERY OF AN EMBOLIZATION COIL WITH AN ATTACHER - An occluding device apparatus includes an embolization coil with a distal end and a proximal end with an opening and an attacher that is threaded through the opening at the proximal end of the embolization coil. The apparatus further comprises a delivery kit for delivery of the embolization coil in a body cavity. The kit comprises a guide catheter for percutaneous introduction of the embolization coil and an inner catheter slidably disposed within the guide catheter during insertion. The inner catheter comprises a proximal end and a distal end. The inner catheter further includes a hub disposed adjacent the proximal end. The kit further comprises a guide wire slidably disposed within the inner catheter. The guide wire is configured to provide a path during insertion thereof within a body cavity. The kit further comprises a pushwire to advance the embolization coil through the inner catheter. | 07-05-2012 |
20120238958 | ADJUSTABLE DIAMETER HEMOSTATIC VALVE - A hemostatic valve device for use in inserting an interventional device into a body lumen of a patient. The valve device includes a housing that defines a cavity between first and second end openings. A valve structure is disposed within the cavity, and defines a variable diameter channel for receiving the interventional device. An annular chamber is generally formed between the valve structure and the housing inner surface, and can be filled with fluid. The housing is movable between first and second positions so that the volume of the cavity and the diameter of the channel vary to a degree for the valve structure to form a seal along the interventional device inserted within the channel. The valve structure may be configured to seal without substantial twisting. | 09-20-2012 |
20140102598 | METHOD OF COATING A STENT - A method of coating a stent is provided that minimizes damage to the coating. The stent is self-expanding and made of a superelastic material. The stent is initially cooled so that at least part of the structure of the stent transforms to a martensitic phase. The stent is then compressed, coated and loaded while the structure of the stent remains at least partially martensitic. After the stent is loaded into a tubular restraint, the loaded stent is allowed to warm to room temperature. | 04-17-2014 |
