HANDLE ASSEMBLY FOR MEDICAL DEVICE DEPLOYMENT SYSTEM

摘要

A medical device deployment system includes an inner shaft telescopically received within a retractable sheath and a medical device positioned over the inner shaft. A handle assembly includes a proximal handle portion having a handle body having an elongate slot therethrough. A distal end of the handle body is attached to an open proximal end of the retractable sheath. The handle assembly also includes a distal handle portion attached to a proximal end of the inner shaft through a connection portion. In a pre-deployment configuration, the connection portion is positioned through a proximal end of the elongate slot and the retractable sheath restricts radial expansion of the medical device. In a post-deployment configuration, the connection portion is positioned through a distal end of the elongate slot and the retractable sheath is retracted such that the medical device is not restricted from radial expansion by the retractable sheath.

主权项

1. A medical device deployment system, comprising:
an inner shaft having an elongate body, a proximal end, a distal end, and a medical device support region at the distal end of the elongate body; a retractable sheath having an elongate tubular body defining a lumen extending from an open proximal end to an open distal end, wherein the inner shaft is telescopically received within the retractable sheath; a medical device positioned over the inner shaft at the medical device support region; and a handle assembly including:
a proximal handle portion having a handle body having an elongate slot therethrough, wherein a distal end of the handle body is attached to the open proximal end of the retractable sheath; anda distal handle portion attached to the proximal end of the inner shaft through a connection portion, wherein the connection portion is positioned through and movable within the elongate slot; wherein the medical device deployment system has a pre-deployment configuration in which the connection portion is positioned through a proximal end of the elongate slot and the retractable sheath restricts radial expansion of the medical device, and a post-deployment configuration in which the connection portion is positioned through a distal end of the elongate slot and the retractable sheath is retracted such that the medical device is not restricted from radial expansion by the retractable sheath.
