20110301569 | Methods and apparatus for the CVCS - The present invention provides an indirect method and accompanying apparatus for supplying a high concentration of medicaments, particularly antibiotics, to the nasal sinuses by first loading the medicament into the cerebrospinal venous system (CVCS) via a Valsalva manuever. Because the CVCS is a valveless, three-dimensional closed system, traditional physiological dogma such as veins always draining tissues does not always apply. Instead, because in its closed-system blood can flow in any direction, the blood of the CVCS and any medicaments that it contains will be drawn to any portion of it where there is increased outflow, such as the copious venous-derived sinus fluid drainage present during nasal allergy or nasal infection. Thus, the very nasal congestion that impedes the effectiveness of direct medicament application, such as seen with nasal inhalers or systemic antibiotics, aids in applying the medicament indirectly to the nasal sinuses via the CVCS. Additionally, the present method has the benefit of delivering medicaments that, unlike present treatment regimens, are not limited solely to those medicaments that can be successfully absorbed from the G.I. tract. This means that, in the case of antibiotics, the bacteria infecting this portion of the CVCS will not be as resistant to treatment if they have not had prior exposure to this new line of antibiotics. Finally, if the infection extends to the eardrums, making the Valsalva maneuver painful, or if the patient is simply unusually sensitive, then earplugs to reduce the stress on the eardrums may be worn while the patient performs the Valsalva maneuver. | 2011-12-08 |

The invention provides for the establishment of artificial antegrade blood flow in the lumen of a target vessel through a path between the outer wall of the balloon catheter and the inner wall of the introducer sheath, through the conduit, through the opening in the balloon catheter, and exiting through the distal end of the balloon catheter. When the occlusion balloon is inflated, there is no back flow in the target vessel and, as the artificial antegrade flow takes place, there is full control of the target vessel blood flow and as a result a significant increase in the safety of the embolization procedures. | 2011-12-08 |
