Abstract
A medial device including a handle portion, and a deployable member disposed in mechanical cooperation with the handle portion is disclosed. The deployable member includes a distal tip and a bend that is disposed adjacent the distal tip. The deployable member is extendable form the handle portion such that the distal tip extends in a spiral-like configuration in response to extension of the deployable member. The spiral-like configuration includes non-equivalent radii.
Claims27
A medical device, comprising;
- a handle portion;
- and
- a deployable member disposed in mechanical cooperation with the handle portion, the deployable member including a distal tip and a bend disposed adjacent the distal tip,
- wherein the deployable member is extendable from the handle portion such that the distal tip extends in a spiral-like configuration in response to extension of the deployable member and wherein the spiral-like configuration includes non-equivalent radii and wherein a portion of the distal tip that is disposed distally of the bend is configured to deploy towards a center of the spiral-like configuration.
An ablation device, comprising:
- a handle portion;
- an inner conductor extending distally from the handle portion and including a length, a proximal portion, a distal tip and a bend disposed adjacent the distal tip;
- and
- an outer conductor surrounding the inner conductor and extending at least partially along the length of the inner conductor, the outer conductor defining a longitudinal axis,
- wherein at least the distal tip of the inner conductor is extendable distally beyond a distal-most end of the outer conductor, and wherein the distal tip extends in a spiral-like configuration in response to extension of the inner conductor, and wherein the spiral-like configuration includes non-equivalent radii, and wherein a portion of the distal tip that is disposed distally of the bend is configured to deploy towards a center of the spiral-like configuration.
A method of treating tissue, comprising:
- providing an ablation device, including:
- a handle portion;
- an inner conductor extending distally from the handle portion and including a length, a proximal portion, a distal tip and a bend disposed adjacent the distal tip;
- and
- an outer conductor surrounding the inner conductor and extending at least partially along the length of the inner conductor, the outer conductor defining a longitudinal axis;
- and
- extending the distal tip of the inner conductor beyond a distal-most end of the outer conductor such that the distal tip extends in a spiral-like configuration having non-equivalent radii and such that a portion of the distal tip that is disposed distally of the bend extends towards a center of the spiral-like configuration.
An ablation device for treating tissue, the ablation device comprising;
- an outer conductor defining a longitudinal axis;
- a dielectric material retained within the outer conductor;
- and
- an inner conductor slidably supported within the dielectric material and extendable from a distal end of the outer conductor and a distal end of the dielectric material, the inner conductor including a bend disposed adjacent a distal tip thereof,
- wherein a distal portion of the inner conductor is biased to a spiral-like configuration having a varying radius along an entire length thereof,
- and wherein a portion of the distal tip that is disposed distally of the bend is configured to deploy towards a center of the spiral-like configuration.
