Retractor device for transforming a retrieval device from a deployed position to a delivery position
First Claim
1. A kit for retrieving material from a body of a subject, the kit comprising:
- a retrieval device including an elongated shaft and a retrieval assembly coupled to a distal zone of the elongated shaft, wherein—
the retrieval assembly includes a capture structure and a cover,the cover has a first portion coupled to the distal zone of the elongated shaft and a free second portion, andthe cover has a first position in which the second portion extends proximally from the first portion, a second position in which the second portion extends distally from the first portion, and the cover surrounds at least a portion of the capture structure in the second position; and
a retractor having a tubular structure that defines a channel configured to slidably receive the retrieval device, wherein the tubular structure has a length no greater than twice a length of the capture structure measured along a longitudinal axis, and wherein the retractor is configured to extend distally beyond the capture structure to facilitate moving the cover from the second position after deployment to the first position for redeployment.

Abstract
Devices and methods for transforming a covered retrieval device from a deployed position to a delivery position for re-use are disclose herein. A retractor device may include, for example, a tubular structure defining a channel and configured to slidably receive a retrieval device. A method for transforming a retrieval device may include, for example, (a) positioning a retrieval device in a deployed position within a channel of a retractor device, (b) securing a part of the cover against a surface of the retractor, and (c) while securing the cover, advancing the retrieval device distally through the tubular structure to expose a capture structure of the retrieval device.
