Abstract
Devices and processes for maintaining a narrow body lumen are described. One embodiment of the inventive device includes: (i) a hydraulic propulsion mechanism for propelling an imaging portion or a therapeutic portion through the narrow body lumen; and (ii) a retrieval mechanism for retrieving the imaging portion or the therapeutic portion from the narrow body lumen.
Claims24
A device for maintaining a narrow body lumen, comprising:
- a hydraulic propulsion mechanism and at least one of an imaging portion or a therapeutic portion, said hydraulic propulsion mechanism configured for propelling said imaging portion or said therapeutic portion relative to said hydraulic propulsion mechanism and through the narrow body lumen, said hydraulic propulsion mechanism including an elongate shaft, wherein the narrow body lumen is distal of a distal end of said elongated shaft;
- wherein said imaging portion or said therapeutic portion, when propelled by said hydraulic propulsion mechanism, is driven distally from said distal end of said elongated shaft and is distally spaced therefrom;
- and
- a retrieval mechanism for retrieving said imaging portion or said therapeutic portion from the narrow body lumen.

A method of maintaining a narrow body lumen, said method comprising:
- sealing the narrow body lumen with a sealing member at a location to allow therapeutic treatment of said narrow body lumen using a therapeutic device;
- hydraulically propelling said therapeutic device distally of a main body and said location through said narrow body lumen;
- treating said narrow body lumen;
- and
- retrieving said therapeutic device from said narrow body lumen.

A method of maintaining a narrow body lumen, said method comprising:
- sealing the narrow body lumen with a sealing member at a location to allow imaging of said narrow body lumen using an imaging device;
- hydraulically propelling said imaging device distally of a main body and said location through said narrow body lumen;
- imaging said narrow body lumen;
- and
- retrieving said imaging device from said narrow body lumen.
2 more elements
A device for maintaining a narrow body lumen, comprising:
- a hydraulic propulsion mechanism and at least one of an imaging portion or a therapeutic portion, said hydraulic propulsion mechanism configured for propelling said imaging portion or said therapeutic portion through the narrow body lumen, said hydraulic propulsion mechanism including an elongate shaft;
- a retrieval mechanism for retrieving said imaging portion or said therapeutic portion from the narrow body lumen;
- and
- a microgenerator which uses a hydraulic propellant to provide power for said imaging portion or said therapeutic portion, and wherein said microgenerator converts hydraulic energy into electrical energy.
