    摘要: Methods, systems and devices for establishing communication between organs and/or tissue lumens. The devices include catheters having magnetized distal ends which are configured to magnetically couple to each other such that a coaxial alignment is established between two or more catheters. The systems include two or more the subject catheters. The methods include use of the catheters and magnetically coupling them to establish a continuous passageway between them.

    摘要: Methods are provided for locally administering an agent to a host. Specifically, the subject methods provide for the local administration of an agent to an interstitial space of a host. In the subject methods, an agent is retroinfused into a vessel of a host, typically a vein, under conditions sufficient for the agent to enter an interstitial space of the host proximal to the vessel location into which the agent is retroinfused. In practicing the subject methods, the agent is administered to the host in combination with the production of vascular stress at the site of administration, where the vascular tissue stress is sufficient to provide for transport of the agent from the vascular site of deposition into the target interstitial space. In a preferred embodiment, the agent is retroinfused at a pressure sufficient to provide for mechanical stress on the vessel proximal to the target interstitial space. Also provided are kits for use in practicing the subject methods. The subject invention finds use in the local administration of a variety of different agents for treatment of a variety of different disease or other conditions.

    摘要: An ultrasound imaging apparatus for measuring the curvature of a vessel consisting of a distal transducer mounted on a transducer supporting device. A resilient deformable material is attached to the transducer supporting device and allows the angular orientation of the transducer to change based on the local vessel curvature. The ultrasound imaging apparatus emits ultrasound radiation from multiple pulsed electronic signals as the apparatus is moved through a vessel or sheath catheter at a known velocity. The distal transducer receives the scattered ultrasound radiation and differences in the phase shifts of the scattered ultrasound radiation are analyzed to detect or measure curvature.
