Abstract
Various components of an interventional therapy assembly are disclosed. One such component is a pointer which may be configured to indicate the disposition of another portion or component of the assembly. A rotary indexing device which may be configured to control or facilitate rotation of other components is also disclosed. Further, various components of an elongate instrument having flexible segments and operative segments are also disclosed. In some embodiments, the elongate instrument may comprise a biopsy assembly and may be used in connection with other components of the disclosed assembly.
Claims20
A rotary indexing assembly, for positioning of a medical device, the rotary indexing assembly comprising:
- a rotary indexing device comprising:
- a base;
- and
- a rotary member rotatably coupled to the base, the rotary member and base engaged such that interaction between the base and the rotary member releasably couples rotation of the rotary member with respect to the base at one or more stops;
- and
- a medical device coupled to the rotary member such that rotation of the rotary member also rotates the medical device.
A method of transvascular therapy, comprising:
- introducing an elongate device into the vasculature of a patient;
- and
- rotating the elongate device about a longitudinal axis between predetermined stop points.
A rotary indexing device, configured for use in connection with a medical instrument, the rotary indexing device comprising:
- a base;
- and
- a rotary member rotatably coupled to the base and configured to be coupled to the medical instrument, the rotary member and base engaged such that interaction between the base and the rotary member releasably couples rotation of the rotary member with respect to the base at one or more stops such that rotation of the rotary member is configured to rotate the medical instrument at positions corresponding to the one or more stops.
