Abstract
A treatment apparatus includes a cannula with a cannula lumen. The cannula has a first average diameter. A probe is positionable in the cannula lumen. The probe has a first section with a second average diameter and a second section with a third average diameter that is less than the second average diameter. At least a portion of the second section has a curved section with at least one radius of curvature. The radius of curvative is selected to provide that as the second section passes through the cannula lumen a first side of the second section is tangential to a first side of the cannula lumen, and a second opposing side of the second section is tangential to a second opposing side of the cannula lumen.
Claims31
A treatment apparatus, comprising:
- a cannula with a cannula lumen and having a first diameter;
- and
- a probe positionable in the cannula lumen, the probe having a distal portion with a curved section that has at least one radius of curvature, the at least one radius of curvature selected to ensure passage of the curved section of the probe through the length of the cannula without interference.
A treatment apparatus, comprising:
- a cannula with a cannula lumen with a first average diameter;
- a probe positionable in the cannula lumen, the probe having a first section with a second average diameter and a second section with a third average diameter that is less than the second average diameter, at least a portion of the second section having a curved section with at least one radius of curvature, the at least one radius of curvative selected to provide that as the second section passes through the cannula lumen a first side of the second section is tangential to a first side of the cannula lumen, and a second opposing side of the second section is tangential to a second opposing side of the cannula lumen.
A method of treatment, comprising:
- providing a treatment device a cannula with a cannula lumen, a probe positionable in the cannula lumen, the probe having a first section with a second average diameter and a second section with a third average diameter that is less than the second average diameter, at least a portion of the second section having a curved section with at least one radius of curvature;
- introducing a distal section of the cannula into a tissue;
- introducing the probe through the cannula lumen with a first side of the second section being tangential to a first side of the cannula lumen, and a second opposing side of the second section being tangential to a second opposing side of the cannula lumen;
- and
- advancing a distal portion of the probe into a tissue site of the tissue.
