Definitions

  • This disclosure relates to medical catheters and assemblies comprising a catheter in combination with a guide tube, sheath or sleeve.
  • the blood pumping action of the heart muscle is critical to sustaining the life of a patient.
  • the tissues of the heart muscle must be continuously supplied and re-supplied with oxygen.
  • the heart muscle To receive an adequate supply of oxygen, the heart muscle must be well perfused with blood.
  • blood perfusion is accomplished with a system of arteries and capillaries.
  • a build-up of plaque may occur inside an artery. These plaque deposits limit blood flow to the portions of the heart that are supplied by the artery. When these deposits build up in the arteries of the heart, this condition is sometimes referred to as coronary artery disease (CAD).
  • CAD coronary artery disease
  • CAD may be treated using relatively non-invasive techniques such as percutaneous transluminal angioplasty (PTA) and percutaneous transluminal coronary angioplasty (PTCA).
  • PTA percutaneous transluminal angioplasty
  • PTCA percutaneous transluminal coronary angioplasty
  • These therapeutic techniques typically involve the use of guidewires, balloon catheters, and stents.
  • the balloon catheter is advanced over the guidewire such that the balloon is positioned within a restriction in a diseased vessel.
  • the balloon is then inflated and the restriction in the vessel is opened.
  • a physician may implant a stent.
  • the stent is implanted through the use of a stent delivery system including a stent delivery catheter and a stent.
  • the device comprises a tubular guiding member and an elongated positioning member extending in a proximal direction beyond the tubular guiding member for advancing and retracting the tubular guiding member in distal and proximal directions.
  • the tubular guiding member comprises an inner tubular member having an outer surface, an elongate support member disposed along a helical path around the outer surface and an encapsulation layer overlaying the outer surface and the elongate support member.
  • the encapsulation layer is mechanically interlocked with and adhered to the elongate support member.
  • the encapsulation layer comprises thermoplastic material from a sheet, the thermoplastic material having melted, mixed and solidified during a reflow process.
  • a feature and benefit of embodiments is a tubular guiding member that is configured and dimensioned to make new treatment options available to physicians.
  • a feature and benefit of embodiments is a device having a tubular guiding member with a thin wall and a high inner diameter to wall thickness ratio to enable medical procedures using combinations of catheters such as a guide catheter, an extension catheter and a therapy catheter (e.g., a stent delivery catheter).
  • the tubular guiding member is dimensioned and configured to be received in a six French guide catheter along with a stent delivery catheter.
  • the tubular guiding member can be received in the lumen of a six French guide catheter and the lumen of the tubular guide member can receive a stent delivery catheter configured for use with a six French guide catheter.
  • the term of art “French” may be defined as three times the diameter of a device as measured in millimeters. For example, a nine French catheter has a three millimeter diameter.
  • the tubular guiding member can be received in the lumen of a selected French size guide catheter and the lumen of the tubular guide member can receive a stent delivery catheter configured for use with the same French size guide catheter.
  • the tubular guiding member has an inner diameter to wall thickness ratio equal to or greater than 24:1.
  • the tubular guiding member has an inner diameter to wall thickness ratio equal to or greater than 22:1.
  • the tubular guiding member has an inner diameter to wall thickness ratio equal to or greater than 18:1.
  • devices are provided with thin walled structures and arrangements having no dedicated marker band.
  • the device includes an elongate support member comprising a core portion comprising a core material and a jacket portion disposed about the core portion.
  • the core material comprises a radiopaque material and the core portion of the elongate support member serves as a sole radiographic marker of the device, the device having no radiopaque marker separate from the elongate support member.
  • structures and arrangements with no dedicated marker band help to provide a thin walled tubular guiding member that is dimensioned and configured dimensioned to make new treatment options available to physicians.
  • the jacket material of the elongate support member has a first radiopacity
  • the core material of the elongate support member has a second radiopacity
  • the second radiopacity is greater than the first radiopacity.
  • the jacket material has an X-ray attenuation coefficient less than 50 l/cm

  • the jacket material comprises stainless steel or nitinol.
  • the core material comprises tantalum.
  • the elongate support member has a rectangular cross-sectional shape and the rectangular cross-sectional shape has a width dimension and a thickness dimension, the width dimension being greater than the thickness dimension. In some embodiments, a ratio of the width dimension to the thickness dimension is greater than four.
  • a feature and benefit of some embodiments is a device having a high pull strength.
  • the device includes an encapsulation layer that is mechanically interlocked with and adhered to a saddle member.
  • a feature and benefit of some embodiments is a device including a guiding member having an overhanging lip of polymer material located at a proximal lumen entrance.
