Abstract: A sheath with an expandable and reducible diameter includes a body having a lumen and that is movable between a first configuration and a second configuration. The body has a first diameter size in the first configuration that is smaller than a second diameter size in the second configuration. The body includes a shaft made from a first material and a wire made from a second material.

Abstract: An expandable dilator for use with an expandable sheath includes a shaft having a tapered distal tip, a body, a proximal end, and a lumen extending longitudinally from the distal tip to the proximal end. The expandable dilator includes an expansion mechanism extending radially outward from the outer surface of the shaft. When the expandable dilator is withdrawn proximally into the expandable sheath, the expansion mechanism engages the distal end of the sheath and expands the sheath as the expansion mechanism moves proximally through the sheath.

Abstract: A device for aiding in recapturing a medical device may include an elongate shaft and an expandable sheath extension coupled to a distal end of the elongate shaft. The expandable sheath extension may be laterally offset from the elongate shaft and may be self-biased toward a radially collapsed configuration. A system for deploying and recapturing a medical device may include a deployment catheter including an elongate tubular member having a lumen configured to slidably receive a medical device, and a device for aiding in recapturing the medical device after the medical device has been deployed. The elongate shaft may be configured to slidably advance the expandable sheath extension through the lumen to a guiding position wherein a proximal end of the expandable sheath extension is disposed within the lumen and a distal end of the expandable sheath extension is disposed distal of the elongate tubular member.

Abstract: A hub and sheath assembly configured to be releasably disposed over a medical device. The hub and sheath assembly may comprise a valve hub including a first body portion, a second body portion, and a lumen extending therethrough and an elongate shaft including a lumen and a seam. The lumen and the seam may extend from a proximal end to a distal end of the elongate shaft. The elongate shaft may be releasably coupled to the valve hub. The seam may be movable from an interlocked configuration configured to hold the elongate shaft in a generally tubular configuration and an open configuration defining an opening extending along a length of elongate shaft.
