Device and method for positioning an object in a body lumen
First Claim
1. A device for positioning an object in a body lumen, the device comprising:
- a liquid filled tube having a proximal end and a distal end;
an injecting apparatus; and
a holding and releasing unit having a bore configured to hold and release the object, wherein the liquid filled tube is detachably connected at its proximal end to the injecting apparatus and detachably connected at its distal end to the holding and releasing unit, such that liquid can pass from the tube into the bore, and wherein the distal end of the tube is capable of being inserted and maneuvered through a body lumen.

Abstract
It is an object of the present invention to provide a device and method for controlled positioning and/or releasing an object in a body lumen.
The device of the invention comprises a liquid filled tube detachably connected to an injecting apparatus at its proximal end and to a holding and releasing unit having a bore configured to hold and release the object, at its distal end. The holding and releasing unit is connected to the tube such that liquid can pass from the tube into the holding and releasing unit bore.
The distal end of the tube is capable of being inserted and maneuvered through a body lumen.
The object is retained in the device during its manipulation through the body lumen due to frictional force exerted by the holding and releasing unit on the object. The object is released by activating the injecting apparatus to achieve an hydraulic pressure in the holding and releasing unit bore which is higher than the frictional force.

12. A method for positioning an object in a body lumen using a device including a holding and releasing unit with a bore and an injecting apparatus for injecting liquid into the bore, the method comprising the steps of:
-
placing the object in the bore of the holding and releasing unit of the device;
holding the object in the bore via a friction fit;
inserting the device into a body lumen;
manipulating the holding and releasing unit to a desired location in the body lumen; and
activating the injecting apparatus of the device to obtain hydraulic pressure in the bore of the holding and releasing unit, wherein the hydraulic pressure is such so as to release the object from the holding and releasing unit. - View Dependent Claims (13, 14)
