Abstract
A flexible lumen (10, 10', 10'', 110, 210) made from a solid, relatively rigid tubing (12, 12', 12'', 112, 212) that is made flexible by cutting a series of grooves (14, 14', 14'', 114, 214) of varying width and depth through the side of the tubing (12, 12', 12'', 112, 212).
Description
FLEXIBLE TUBE WITH CIRCULAR GROOVES OF VARYING WIDTH AND DEPTH
Background of the Invention
This invention relates generally to the field of catheters and more particularly to steerable catheters. Medical catheters generally comprise flexible tubular members that may be inserted into the body through an incision. Some of these catheters may be twisted or steered by an internal guidewire. See, for example, U.S. Patent Nos. 4.921,482, 4,998,916, 5,037,391, 5,108,368, 5,203,772, 5,308,324, 5,372.587 and 5,378,234 (Hammerslag, et al.), U.S. Patent No. 5,217,465 (Steppe), U.S. Patent Nos. 5,242,449 and 5,364,405 (Zaleski) and U.S. Patent No. 5,084,012 (Kelman), the entire contents of which are incorporated herein by reference.
Prior steerable catheters generally use a helical coil made of metal or plastic. The coil either surrounds flexible plastic tubing or the coil is coated with an elastomer to seal the coil fluid tight. The coil is rigid enough to resist collapse but flexible enough to be steered. Coils of this type, however, are difficult to bend at large angles without causing permanent deformation of the coil, and it can be difficult and relatively expensive to manufacture a coil of variable spring constant.
Accordingly, a need continues for a flexible catheter coil that is easy and inexpensive to manufacture and that can be bent at large angles without permanent deformation.
Brief Summary of the Invention
The present invention improves upon the prior art by providing a flexible lumen made from a solid, relatively rigid tubing that is made flexible by cutting a series of grooves of varying width and depth through the side of the tubing. Accordingly, one objective of the present invention is to provide a flexible catheter lumen that is relatively easy and inexpensive to manufacture.
Another objective of the present invention is to provide a flexible catheter lumen having good torsional stability.
These and other advantages and objectives of the present invention will become apparent from the detailed description and claims that follow.

Detailed Description of the Invention
As best seen in FIGS. 1 , 2 and 3, lumen 10 of the present invention generally consists of relatively rigid tube 12 into which a series of grooves 14 are cut, leaving a series of bands 16 held together by spine 18. As seen in FIGS. 4 and 5, grooves 14' and 14" can be of varying width and depth to effect the desired flexibility of lumens 10' and 10", respectively. Grooves 14, 14' or 14" may be parallel, or cut at any suitable angle. Tubes 12, 12' and 12" may be made from a variety of suitable materials such as plastic,
stainless steel or titanium and may be of any suitable thickness, varying or constant inside diameter or outside diameter.
Alternatively, as best seen in FIGS. 6, 7 and 8, lumen 110 can consist of tubing length 112 into which a series of opposing grooves 1 14 and 115 have been cut, leaving a series of semicircular bands 1 16 held together by a plurality of spines 1 18. The use of a plurality of spines 118 increases the torsional rigidity of lumen 110.
Lumens 10, 10', 10" and 1 10 may be made as a separate piece, as illustrated in FIGS. 1-8 or, as illustrated in FIG. 9, lumen 210 may be formed on the end of a relatively long tube 212. Such a structure eliminates the need to attach and seal lumen 210 to the end of a separate aspiration tube (not shown).
In use, lumens 10, 10', 10", 1 10 and 210 are sealed fluid tight by methods well- known in the art. The mechanism used to steer lumens 10, 10', 10", 1 10 and 210 are also well-known in the art. One preferred method is the use of one or more push/pull wires 20, 20', 20", 120 or 220. The operation of push/pull wires 20, 20', 20", 120 or 220 is fully disclosed in U.S. Patent Nos. 5,217.465 (Steppe) and 5,378,234 (Hammerslag, et al.) and is incorporated herein by reference.
This description is given for purposes of illustration and explanation. It will be apparent to those skilled in the relevant art that changes and modifications may be made to the invention described above without departing from its scope or spirit.
