Abstract
A catheter having improved steering and torque transmission capabilities.
Claims49
An catheter, comprising:
- a hollow catheter body defining a proximal portion and a distal portion;
- at least one internal component within the distal portion of the catheter body;
- adhesive material located within the distal portion of the catheter body about the at least one internal component;
- and
- a torque transfer device located within at least a portion of the adhesive material and adapted to engage at least a portion of the at least one internal component and transfer torque to the at least one internal component.
2 more elements
A steering mechanism for use with a catheter, comprising:
- a steering center support defining a distal end;
- and
- at least one steering wire connected to the center support a sufficient distance from the distal end of the center support to provide a straight distal end when the steering wire is activated to bend the center support.
An apparatus for creating a lesion in body tissue, comprising:
- a catheter body having a distal assembly including a steering mechanism adapted to cause the distal assembly to contact body tissue along the length of the distal assembly;
- and
- at least two electrodes supported by the distal assembly and capable of creating generally elliptical lesions at least 2 cm long and 7 mm deep which are substantially continuous and uniform in depth when a source of radiofrequency energy simultaneously conveys radiofrequency energy to the at least two electrodes.
A catheter, comprising:
- a hollow catheter body having a side wall and an aperture extending through a predetermined portion of the side wall;
- at least one internal component located within the catheter body;
- and
- adhesive material located within the hollow catheter body such that at least a portion of the adhesive material is in the vicinity of the side wall aperture, the adhesive material securing the hollow catheter body to the at least one internal component.
1 more element
A catheter, comprising:
- a hollow catheter body proximal member defining a distal region;
- a hollow catheter body distal member defining a proximal region, the distal and proximal members being respectively located such that one of the distal region of the proximal member and the proximal region of the distal member overlaps the other, thereby creating an overlapping region;
- a bond at the overlapping region securing the proximal member to the distal member;
- and
- at least one internal component located within at least the distal member.
