Loading a tissue closure device onto a delivery device

摘要

A compression tool is configured to compress one or more components of a delivery device, such as a closure element and one or more flanges of a pusher tube. The compression tool includes clamping means configured to close or release with rotation of actuating means (e.g., rotating means). In a closed position, the clamping means can sufficiently compress the one or more components of the delivery device so that a technician can easily position a garage tube about the compressed delivery device components. The assembled delivery device (or assembled garage tube) can then be removed from the compression tool upon reverse rotation of the actuating means, and subsequent opening of the clamping means.

1. A compression tool configured to compress a closure element of a preliminary assembly of a medical delivery device, the compression tool comprising:
a base configured with a receiving means, the receiving means being configured to receive the closure element of the preliminary assembly of the medical delivery device on a first side, and on a second side to receive a garage tube that is sized and configured to accommodate insertion of the closure element in a compressed configuration; a clamping means positioned about the receiving means, the clamping means including a clamp being configured to slide radially in a linear direction toward or away from the receiving means, the clamp including a differentially shaped contact portion having a first portion that includes a first surface sized and configured to clamp against the closure element and a second surface sized and configured to accommodate insertion of the garage tube, the second surface being recessed radially relative to the first surface; an actuation means configured to, upon application of force in one direction, rotate about a rotation axis in a first direction relative to the base, thereby sliding the clamp of the clamping means radially in a linear direction toward the receiving means, and upon application of force in an opposite direction, rotate in a second direction, opposite to the first direction, relative to the base thereby sliding the clamping means away from the receiving means; and wherein the clamp of the clamping means is configured to remain stationary in longitudinal direction along the rotation axis as the clamp slides in the linear direction toward the receiving means.
