Medical device with anchor members
First Claim
1. An implantable medical device comprising:
- a frame having a longitudinal axis, the frame having a collapsed configuration and an expanded configuration, and being configured to move from the collapsed configuration to the expanded configuration;
an elongate anchor having a first end coupled to the frame and a second movable end that is slidably disposed within a retaining structure on the frame and is longitudinally slideable relative to the frame,wherein, when the frame is in the collapsed configuration, the anchor is disposed within the frame; and
when the frame is in the expanded configuration, at least a portion of the anchor extends out of the frame at an angle to the axis.

Abstract
An implantable medical support frame (104) having a central longitudinally extending axis is expandable from a collapsed configuration having a first diameter to an expanded configuration having a second diameter. The frame also includes an anchoring mechanism with an elongate member (110). At least a portion of the elongate member is slidably disposed within a retaining structure when the frame is in the collapsed configuration. When the frame expands from the collapsed configuration to the expanded configuration, a portion of the elongate member is advanced out of the retaining structure such that the portion of the elongate member protrudes radially outward of the frame at an angle to the axis, thereby forming an anchor. A length of the protruding portion of the anchor increases as the frame expands from the collapsed configuration to the expanded configuration.

8. An endoluminal prosthesis comprising:
-
a radially expandable frame having a central longitudinally extending frame axis, a first frame location, a second frame location, a collapsed configuration, and an expanded configuration; and a barb having a first end coupled to the frame at the first frame location, a second end, and an elongate body extending away from the first frame location toward the second frame location, wherein at least a portion of the barb is slidably disposed within a part of the frame at the second frame location and is longitudinally slideable relative to the frame, and a portion of the barb protrudes from a retaining structure at an angle to the frame axis and forms an anchor when the frame is in the expanded configuration, and wherein a distance between the first and second frame locations decreases and a length of the protruding portion of the barb increases as the frame expands from the collapsed configuration to the expanded configuration. - View Dependent Claims (9, 10, 11, 12)

13. An endoluminal prosthesis comprising:
-
a radially expandable frame having a central longitudinally extending axis, the frame having a collapsed configuration and an expanded configuration, and being configured to move from the collapsed configuration to the expanded configuration, wherein the frame comprises at least one cell, the cell including a first strut member connected to a second strut member by a first bend, the first and second strut members forming a first angle extending toward a center of the cell, and a third strut member connected to a fourth strut member by a second bend, the third and fourth strut members forming a second angle extending toward a center of the cell, the first and third strut members being connected by a first connecting member and the second and fourth strut members being connected by a second connecting member; and a barb member fixedly connected to the frame at the first bend, the barb member having an elongate body extending away from the first bend toward the second bend and is longitudinally slideable relative to the frame, wherein, when the frame is in an expanded configuration, a first portion of the elongate body is slidably disposed within the cell, and a second portion of the elongate body protrudes radially outward of the cell and forms an anchor, wherein a longitudinal distance between the first and second bends decreases and a length of the protruding portion of the elongate body increases as the frame expands from the collapsed configuration to the expanded configuration. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
