摘要： A catheter assembly includes an elongate member and a balloon. The elongate member defines at least one lumen and an outer surface. The outer surface defines at least one opening in fluid communication with the at least one lumen. The balloon is disposed within the at least one lumen. The balloon is inflatable such that a portion of the balloon expands from the at least lumen through the at least one opening. The expansion of the balloon increases the flow restriction through the at least one opening compared to the flow restriction through the at least one opening when the balloon is in a deflated condition. Methods for using a catheter assembly to remove occlusive material from a catheter are also described.

摘要： An immunotherapy delivery device is provided including a catheter and a pressure modulating device fixed adjacent the distal end of the catheter. In accord with aspects of the device, the lumen of the catheter is coated to facilitate delivery of a healthy immunotherapy agent. A method for delivering an immunotherapy agent to a tumor includes advancing the delivery device into a vessel of a patient, and infusing the agent under pressure into the vessel to penetrate the tumor. The delivery device prevents reflux of the agent toward non-treatment sites.

摘要： A radiopaque, optically translucent thermoplastic polyurethane compound is disclosed. The use of nano-sized particles of barium sulfate optionally in combination with a minor amount of certain dispersion aids allows the barium sulfate to be sufficiently dispersed within the thermoplastic polyurethane to retain optical translucency according to a defined Haze Determination Test. Medical devices, needing both visual spectrum observation before and during in-vivo medical use and radiopacity monitoring during in-vivo medical use, benefit from this compound. Optionally, a surface enhancer can also be used.

摘要： Methods for creating nanostructured surface features on polymers and polymer composites involve application of low pressure during curing of solid polymer material from a solvent solution. The resulting nanoscale surface features significantly decrease bacterial growth on the surface. Polymer materials having the nanoscale structuring can be used in implantable medical devices to inhibit bacterial growth and infection.

摘要： An implantable catheter is provided that may be disinfected without removal from the body of a patient, using an electrochemical method to generate an electric field on the catheter surface and thus destroy microorganisms in a biofilm that is present or forming. A catheter system includes the implantable catheter and a voltage source that is operably connected to electrodes on or embedded in the exterior and optionally the interior catheter surface. Methods are also provided for disinfecting the implantable catheter in vivo and for detecting or confirming the presence of a pathogenic biofilm thereon.

摘要： Catheter includes an outer shaft member having a proximal section and a distal outer member. The outer shaft has an inflation lumen defined therethrough. A balloon is in fluid communication with the inflation lumen and has a proximal balloon shaft, a proximal cone portion, a working length, a distal cone portion, and a distal balloon shaft. Catheter also includes a monolithic inner tubular member extending from the outer shaft proximal section through the distal outer member and through the balloon to form a tip. The distal balloon shaft has an inner diameter and comprises a distal seal portion coupled to the inner tubular member and a proximal portion free of attachment to the inner tubular member. The length of the proximal portion of the distal balloon shaft is at least about two times the inner diameter of the distal balloon shaft. Methods of making a catheter are also provided.

摘要： A peelable protective sheath and related assemblies/systems and methods are disclosed. The protective sheath may be used on a balloon catheter to protect the balloon and any coating thereon. The protective sheath may be peelable to make removal of the protective sheath easier. The peelable protective sheath may be inserted into a hemostatic valve and introducer while still disposed over the balloon of a balloon catheter to protect the balloon and any bioactive coating thereon from damage during insertion. The peelable protective sheath may be peeled from a proximal end to initiate removal. Alternatively, the peelable protective sheath may be peeled from a distal end of the peelable protective sheath as the balloon catheter is inserted through a hemostatic valve and introducer.
