Abstract
A device is provided for insertion and implantation in a patient's bodily canals or vessels such as the ureter. The device includes interconnected loops that form a flexible structure that may span the length of a bodily canal. The device may include retaining elements at both or either ends. Further according to the present invention, there is provided a stylet for delivering the device to the desired body canal. The device minimizes contact with the lining of the bodily canal while retaining the patency of the canal. The device also is adjustable in length and shape. It is particularly useful for maintaining the tortousness of a body canal.
Claims27
A device for treating a body canal, comprising:
- a proximal end-piece positioned at a proximal end of said device;
- a distal end-piece positioned at a distal end of said device;
- and
- an elongated body portion disposed between said proximal end-piece and said distal end-piece, said body portion comprising a plurality of interconnected loops configured to fit within said body canal, each of said loops comprising a member defining at least one opening, the member of each loop passing through at least one opening of another loop to form said plurality of interconnected loops.
A delivery assembly for delivering a interventional device to a body site, comprising:
- an interventional device for treatment of a body site comprising a proximal end-piece, a distal end-piece, and an elongated body portion;
- and
- a stylet for positioning said interventional device at said body site, said stylet reversibly attachable to said proximal end-piece and free of said distal end-piece and said elongated body portion.
A method for treating a body canal in a patient, comprising:
- inserting an interventional device into a body canal of a patient, said interventional device comprising a proximal end-piece positioned at a proximal end of said device, a distal end-piece positioned at a distal end of said device, and an elongated body portion disposed between said proximal end-piece and said distal end-piece, said body portion comprising a plurality of interconnected loops configured to fit within said body canal, each of said loops comprising a member defining at least one opening, the member of each loop passing through at least one opening of another loop to form said plurality of interconnected loops;
- and
- positioning said interventional device in said body canal.
