STEERABLE MEDICAL DEVICE FOR TISSUE DISRUPTION
First Claim
1. A method, comprising:
- inserting a distal end portion of a medical device into a biological body such that a cutting member disposed at a distal end of the medical device is at a first location within the biological body;
disrupting tissue at the first location within the biological body;
reconfiguring the distal end portion of the medical device from a first configuration in which the distal end portion of the medical device has a first curvature to a second configuration in which the distal end portion of the medical device has a second curvature different than the first curvature to position the cutting member at a second location within the biological body; and
after the reconfiguring, disrupting tissue at the second location within the biological body.

Abstract
Apparatuses and methods for accessing and disrupting a tissue are disclosed herein. In one embodiment, a method includes inserting a distal end portion of a medical device into a biological body such that a cutting member disposed at a distal end of the medical device is at a first location within the biological body. A tissue is disrupted at the first location within the biological body. The distal end portion of the medical device is reconfigured from a first configuration in which the distal end portion of the medical device has a first curvature to a second configuration in which the distal end portion of the medical device has a second curvature different than the first curvature and the cutting member is at a second location within the biological body. A tissue is then disrupted at the second location within the biological body.

9. A method, comprising:
-
inserting a distal end portion of a medical device into a biological body while the distal end portion of the medical device is in a substantially linear configuration, the medical device including an expandable member disposed at a distal end of the medical device, the expandable member being disposed at a first region within the biological body during the inserting; moving the expandable member to an expanded configuration after the inserting; rotating the expandable member while in the expanded configuration such that tissue is disrupted within the biological body at the first region; and moving the distal end portion of the medical device to a curved configuration while disposed within the biological body such that the expandable member is disposed at a second region within the biological body different from the first region. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. An apparatus, comprising:
-
a first elongate member; and a second elongate member coupled to the first elongate member, the second elongate member movable between a constrained configuration in which a distal end portion of the first elongate member has a first curvature and an unconstrained configuration in which the distal end portion of the first elongate member has a second curvature different than the first curvature, the first elongate member and the second elongate member collectively configured to be inserted into a biological body when the second elongate member is in the constrained configuration, the distal end portion of the first elongate member being movable to the second curvature while disposed within the biological body. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
