Abstract
An athertome assembly comprises a series of spanning and descending members extended between a segmented base and a cutting surface. This athertome assembly configuration provides both flexibility and structural strength which facilitates the implantation of medical devices.
Claims18
A medical device assembly comprising:
- an expandable balloon having a central longitudinal axis;
- and
- an athertome disposed on the expandable balloon, the athertome having a first end and a second end opposite the first end, the athertome comprising:
- i) a cutting member extending from the first end to the second end, the cutting member having a cutting edge along a first side of the cutting member and a second side opposite the first side;
- ii) a base member mounted to the expandable balloon, the base member extending continuously from the first end of the athertome to the second end of the athertome;
- iii) a first spanning member extending from the second side of the cutting member to the base member;
- iv) a second spanning member extending from the second side of the cutting member to the base member;
- v) a descending member positioned between the first spanning member and the second spanning member, a first through hole at least partially defined between the first spanning member and the descending member and a second through hole at least partially defined between the second spanning member and the descending member, the descending member extending from the second side of the cutting member toward the base member;
- and
- vi) a connector connecting the descending member to the base member, the connector having a width substantially narrower than a width of the descending member.

- iii) a first spanning member extending from the second side of the cutting member to the base member proximate the first end of the athertome;
- iv) a second spanning member extending from the second side of the cutting member to the base member proximate the second end of the athertome;
- v) one or more descending members positioned between the first spanning member and the second spanning member, the one or more descending members extending from the second side of the cutting member toward the base member;
- and
- vi) a connector connecting each of the one or more descending members to the base member, the connector having a width substantially narrower than a width of each of the one or more descending members.
