Definitions
- the present invention relates to catheters used to remove material from a site in a body lumen. More particularly, this invention pertains to catheters capable of capturing the material removed from the site.
- Atherosclerosis is a progressive disease of the vascular system whereby atheroma is deposited on the inner walls of blood vessels. Over time atheromatous deposits can become large enough to reduce or occlude blood flow through the vessels, leading to symptoms of low blood flow such as pain in the legs (on walking or at rest), skin ulcer, angina (at rest or exertional), and other symptoms. To treat this disease and improve or resolve these symptoms it is desirable to restore or improve blood flow through the vessel.
- Atherectomy catheters can be used to remove atheromatous deposits from the blood vessel and can present an ideal solution when the atheromatous debris removed from the vessel is captured and removed from the body.
- One problem that occurs when removing material from a blood vessel is that material fragments may be created by the removal means, in some cases by a cutter, and such fragments may be left in the body where they can embolize and cause problems. It is desirable to remove from the body all material fragments created at the time of material removal from a vessel wall. Some catheters are designed to remove material from the body by directing material particles into a collection chamber however these collection efforts are not always 100% effective. Improved particle collection means are needed.

- the cutting element has a sharp cutting edge that surrounds a cup-shaped surface. Cut material is directed into the collection chamber by the cup-shaped surface and by fluid flow.
- an atherectomy catheter 2 which has a cutting element 4 , which is used to cut material from a blood flow lumen such as a blood vessel.
- the cutting element 4 is movable between a stored position ( FIG. 2 ) and a cutting position ( FIG. 3 ) relative to an opening 6 in a body 8 of the catheter 2 .
- the cutting element 4 moves outwardly relative to the opening 6 so that a portion of the element 4 extends outwardly from the body 8 through the opening 6 .
- the cutting element 4 may be positioned relative to the body 8 and opening 6 so that less than 90 degrees of the cutting element 4 is exposed to cut tissue. In other embodiments more of the cutting element 4 may be exposed without departing from numerous aspects of the invention.
- Distal end of catheter 2 is positioned near a treatment site of a vessel with cutting element 4 in the stored position. Then catheter 2 is moved distally through the vessel with the cutting element 4 in the working or cutting position as described in further detail below. As the catheter 2 moves through the blood vessel with the cutting element 4 in the working or cutting position the tissue material is cut by the cutting element 4 and is directed into a tissue chamber 12 positioned distal to the cutting element 4 .
- the tissue chamber 12 may be somewhat elongated to accommodate the tissue which has been cut.
- cutting element 4 is moved proximally from the stored position so that a cam surface 14 on the cutting element 4 engages a ramp 16 on the body 8 of the catheter 2 .
- the interaction between the cam surface 14 and the ramp 16 causes the cutting element 4 to move to the cutting position and also causes a tip 18 to deflect which tends to move the cutting element 4 toward the tissue to be cut.
- the cutting element 4 has a cup-shaped surface 24 , which directs the tissue cut by the cutting edge 22 into the tissue chamber 12 .
- Cutting edge 22 may be at a radially outer edge 23 of the cutting element 4 .
- the cup-shaped surface 24 may be a smooth and continuous surface free of through holes, teeth, fins or other features, which disrupt the smooth nature of the surface 24 for at least half the distance from the longitudinal axis LA to the outer radius at the cutting edge 22 .
- the cup-shaped surface 24 may also be free of any such features throughout an area of at least 300 degrees relative to the longitudinal axis LA.
- the cup-shaped surface may have a limited amount of through holes, teeth, fins or other features as described in further detail below.
- One or more raised elements 26 may extend outwardly from the cup-shaped surface 24 with FIG. 4 showing two raised elements 26 .
- the raised element 26 is a small wedge of material that rises relatively abruptly from the cup-shaped surface 24 .
- the raised element 26 helps to break up hard tissue and plaque by applying a relatively blunt striking force to the hard tissue or plaque since cutting such tissue with the cutting edge 22 may not be effective, and strips of such hard tissue may not be flexible enough to be redirected by cup-shaped surface 24 into collection chamber 12 .
- the raised elements 26 altogether occupy a relative small part of the cup-shaped surface 24 .
- the raised elements 26 do not interfere with the ability of the cutting element 4 cup-shaped surface 24 to cut and re-direct large strips of tissue into the tissue chamber while still providing the ability to break up hard tissue and plaque with raised element 26 .
- the cutting element 4 is coupled to a shaft 20 that extends through a lumen 21 in the catheter 2 .
- Catheter 2 is coupled to exemplary cutter driver 5 .
- Cutter driver 5 is comprised of motor 11 , power source 15 (for example one or more batteries), microswitch (not shown), housing 17 (upper half of housing is removed as shown), lever 13 and connection assembly (not shown) for connecting shaft 20 to driver motor 11 .
- Cutter driver 5 can act as a handle for the user to manipulate catheter 2 .
- Lever 13 when actuated to close the microswitch, electrically connects power source 15 to motor 11 thereby causing rotation of cutting element 4 .
- the cutting element 4 is rotated about a longitudinal axis LA when the shaft 20 rotates.
- the cutting element 4 is rotated at about 1 to 160,000 rpm but may be rotated at any other suitable speed depending upon the particular application. Further description of catheters similar to catheter 2 is found in U.S. Patent Application Publication No. U.S. 2002/0077642 A1 to Patel et. al., entitled “Debulking Catheter”, the contents of which are hereby incorporated by reference herein.
- catheter 2 cuts softer atheroma from a vessel wall in relatively large strips and cup-shaped surface 24 directs these strips through opening 6 into collection chamber 12 .
- Smaller particles in some cases produced during the removal of harder or calcified atheroma, can be directed towards opening 6 by the cup-shaped surface 24 and can also be directed tangentially to the spinning cutting element outer edge 23 , in some cases past opening 6 and in this event not collected in chamber 12 .

In other embodiments these flow rates are achieved at driving pressures of 1, 5, 10, 20, 100 or 150 psi (6.9, 35, 69, 140, 690, or 1000 kilopascal), or at pressures therebetween.
- Vent holes 31 allow fluid to flow out of interior 68 of collection chamber 12 without allowing significant particles of material to pass therethrough.
- vent hole diameter is 50 microns.
- vent hole diameter is from 25 to 200 microns, including 25, 35, 65, 80, 100, 150 or 200 microns.

- the holes can be uniformly or non-uniformly distributed over the outer surface of collection chamber 12 .
- more than half of the holes are distributed over the proximal half of the outer surface of collection chamber 12 so that flow from interior 68 of collection chamber 12 is preserved as holes of the collection chamber become blocked by particles and fragments.

- catheter 2 B has improved material collection capability and is additionally comprised of tube 7 , fluid source (not shown) and vent holes 31 in wall of collection chamber 12 .
- Tube 7 is attached to the fluid source with a leak-tight fluid connection such as a gasketed mechanical seal in the vicinity of cutter driver 5 .
- the fluid source in some embodiments, provides flow only when cutter 4 is rotating, for example by means of a valve, so as to prevent infusion of excessive fluid into a patient.
- the fluid source can provide flow before, during or after rotation of cutting element 4 , or any combination of before, during or after rotation of cutting element 4 .

- the distal end of tube 7 can be oriented in any direction ranging from towards the side wall of collection chamber 12 to towards the distalmost end of collection chamber 12 . In one embodiment the distal end of tube 7 is oriented towards distal region 68 d of interior 68 of collection chamber 12 .
- tube 7 has a one way valve that allows flow distally through the tube but prevents flow proximally through the tube so as to prevent blood or debris from entering tube 7 and potentially clogging the lumen of tube 7 .
- the lumen diameter and length of tube 7 are sized so as to permit fluid flow rates of 0.5 to 50 cc/min, including 0.5, 1, 2, 5, 10, 20, or 50 cc/min, or other flow rates at a driving pressure of 50 psi (345 kilopascal). In other embodiments these flow rates are achieved at driving pressures of 1, 5, 10, 20, 100 or 150 psi (6.9, 35, 69, 140, 690, or 1000 kilopascal), or at pressures therebetween.
