Definitions

  • 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.
  • 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.
  • FIG. 1 is a perspective view of the first embodiment of the lumen of the present invention.
  • FIG. 2 is a side elevational view of the first embodiment of the lumen of the present invention.
  • FIG. 3 is a cross-sectional view of the first embodiment of the lumen of the present invention taken along line 3-3 in FIG. 2.
  • FIG. 4 is a side elevational view of the second embodiment of the lumen of the present invention.
  • FIG. 5 is a side elevational view of the third embodiment of the lumen of the present invention.
  • FIG. 6 is a front elevational view of the fourth embodiment of the lumen of the present invention.
  • FIG. 7 is a front elevational view of the fourth embodiment of the lumen of the present invention.
  • FIG. 8 is a cross-sectional view of the fourth embodiment of the lumen of the present invention taken along line 8-8 in FIG. 7.
  • FIG. 9 is a front elevational view of the fifth embodiment of the lumen of the present invention.
  • 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.
  • 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.
  • 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).
  • 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.

Abstract

L'invention concerne une lumière (10, 10', 10', 110, 210) flexible constituée d'un tubage (12, 12', 12', 112, 212) qu'on rend flexible en coupant une série de cannelures (14, 14', 14', 114, 214) de diverses largeurs et profondeurs sur le côté du tubage (12, 12', 12', 112, 212).
