Abstract
In general, medical sheath systems that can employ retainer devices having a plurality of channels configured to retain a sheath assembly in one or more curved configurations are described. In one embodiment, a retainer device may releasably retain a curvable tube of the sheath assembly in any of multiple curved configurations that range, for example, in selectable increments between 0° to 180°.
Claims20
A method of using a sheath assembly, the method comprising:
- positioning a curvable tube relative to a patient access opening of a patient, the curvable tube comprising a first end, a second end, and a lumen extending between the first end and the second end, the second end of the curvable tube comprising a port configured to receive an interventional tool for delivery through the patient access opening;
- bending the curvable tube into a curved configuration;
- retaining the curvable tube in the curved configuration by positioning the curvable tube in at least one tube retainer of a retainer, the retainer including a plurality of tube retainers configured to releasably retain the curvable tube in a plurality of configurations including a first configuration in which the curvable tube is releasably retained in a 90° curve by the retainer while the interventional tool is advanced through the curvable tube and through the patient access opening and a second curved configuration in which the curvable tube is releasably retained in a 180° curve by the retainer while the interventional tool is advanced through the curvable tube and through the patient access opening;
- and
- advancing an interventional tool through the curvable tube and through the patient access opening while the retainer, the first end of the curvable tube, and the second end of the curvable tube remain in a fixed position relative to the patient access opening such that the curvable tube is retained in the curved configurations while the interventional tool is advanced through the curvable tube and through the patient access opening.

- bending the curvable tube into a curved configuration;
- retaining the curvable tube in the curved configuration by positioning the curvable tube in at least one tube retainer of a retainer, the retainer including a plurality of tube retainers configured to releasably retain the curvable tube in a plurality of configurations including a first configuration in which the curvable tube is releasably retained in a 90° curve by the retainer while the interventional tool is advanced through the curvable tube and through the patient access opening and a second curved configuration in which the curvable tube is releasably retained in a 180° curve by the retainer while the interventional tool is advanced through the curvable tube and through the patient access opening;
- anchoring a base of the retainer to a support surface;
- and
- advancing an interventional tool through the port of the curvable tube and through the patient access opening while the base, the first end of the curvable tube, and the second end of the curvable tube remain in a fixed position relative to the patient access opening, the interventional tool entering the curvable tube in a first direction and exiting the curvable tube in a second direction, the first direction rotated at least 90° relative to the second direction, while the first and second ends of the curvable tube remain in a fixed position relative to the patient access opening.
