Twist-grip anchors and methods of use

摘要

Devices, systems and methods are provided for anchoring implantable medical devices to maintain an implanted position. In particular, twist-grip anchors are provided. In some embodiments, the twist-grip anchor comprises a first support having a first lumen, a second support having a second lumen, and a sleeve having a first end fixedly attached to the first support and a second end fixedly attached to the second support, wherein the first and second supports and the sleeve are aligned to allow the passage of the elongate device through the first lumen, second lumen and sleeve, and wherein rotation of at least the first support twists the sleeve so that the sleeve engages the elongate device in a manner that resists movement of the elongate device in relation to the sleeve. The anchor is then attached to the tissue, such as by suturing.

主权项

1. An anchor for anchoring an elongate device to tissue within a patient comprising:
a first support having a first lumen; a second support having a second lumen; a sleeve having a first end fixedly attached to the first support, a second end fixedly attached to the second support, and an axial length, wherein the first and second supports and the sleeve are alignable to allow the passage of the elongate device through the first lumen, second lumen and sleeve having the axial length, and wherein manual rotation of at least the first support twists the sleeve while maintaining the same axial length of the sleeve so that the sleeve engages the elongate device in a manner that resists movement of the elongate device in relation to the sleeve, and wherein the anchor is configured for attachment to the tissue; and a locking mechanism to lock the first and second supports in relation to each other.
