Abstract
A catheter assembly comprises a catheter shaft having a first region and a second region. The first region is less radiopaque than the second region. The first region is constructed of a shaft material and the second region is constructed from the shaft material in combination with at least one radiopaque material. At least a portion of the shaft material of the second region defines at least one grooved region. The at least one radiopaque material is positioned at least partially within the at least one grooved region.
Claims41
A catheter assembly comprising:
- a catheter shaft, the catheter shaft comprising a first region and a second region, the first region being less radiopaque than the second region, the first region being constructed of a shaft material, the second region being constructed of the shaft material in combination with at least one radiopaque material, at least a portion of the shaft material of the second region defining at least one grooved region, the at least one radiopaque material being positioned at least partially within the at least one grooved region.
A method of forming a radiopaque catheter shaft comprising the steps of:
- forming a first tubular member;
- forming a second tubular member;
- placing at least one member of radiopaque material into at least a portion of the second tubular member;
- and
- engaging at least one end region of the second tubular member to at least one end region of the first tubular member.
A method of forming a radiopaque catheter shaft comprising the steps of:
- forming a tubular member;
- swaging at least one member of radiopaque material into at least a portion of the tubular member, at least one member of radiopaque material having a length substantially equal to that of a stent
- disposing the stent about the at least a portion of the tubular member such that the at least one member of radiopaque material underlies substantially the entire length of the stent.
A method of forming a radiopaque catheter shaft comprising the steps of:
- forming a tubular member, the tubular member having a first portion and a second portion, the first portion having a first outer diameter and the second portion having a second outer diameter;
- forming at least one indentation into the second portion of the tubular member;
- and
- placing at least one radiopaque material into the at least one indentation, the first outer diameter and the second outer diameter being substantially equal.
The method of claim 36 wherein the at least one indentation is selected from the group consisting of:
- valleys, grooves, channels, pores and any combinations thereof.
A method of forming a radiopaque catheter shaft comprising the steps of:
- forming a tubular member, the tubular member having a first portion and a second portion, the first portion having a first outer diameter and the second portion having a second outer diameter;
- forcing at least one member of radiopaque material into the second portion, the first outer diameter and the second outer diameter being substantially equal.
