Abstract

Delivery device assemblies useful in the delivery of implantable medical devices, such as endografts, into a vascular system are described. A delivery device has a handle having a handle body, at least one actuator mounted to the handle body for rotation about the handle body, the actuator having a follower-driver. For each actuator, at least one follower is disposed around the handle body and is configured to rotate about the handle body. A hard stop on the handle body arrests rotation of a distal most follower for each actuator. Delivery systems, methods of making a delivery device, methods of making a delivery system, and methods of delivering an implantable medical device to a point of treatment in a body lumen are also described.

Claims20

Dependent claims

A delivery device for delivering an implantable medical device into a body lumen of a patient, the delivery device comprising:

a handle assembly having a lengthwise axis and comprising:
a proximal handle portion;
a distal handle portion having a distal handle body defining a circumferential channel and a hard stop adjacent the circumferential channel;
a plurality of followers disposed within the circumferential channel and individually rotatable about the distal handle body, each follower of the plurality of followers having a follower body and a lug having an axially extending cantilever portion with a first face and a second face, the cantilever portion of a first follower of the plurality of followers extending axially over the follower body of an adjacent second follower of the plurality of followers such that a second face of the first follower of the plurality of followers contacts a first face of the second follower of the plurality of followers upon rotation of the first follower about the distal handle body;
and
an actuator disposed over the plurality of followers and rotatable about the distal handle body, the actuator defining a follower driver extending radially inward toward the distal handle body and configured to contact the first face of the first follower of the plurality of followers such that rotation of the actuator drives rotation of the first follower of the plurality of followers;
an inner elongate member extending from the handle assembly;
and
a sheath disposed over the inner elongate member.

A delivery device for delivering an implantable medical device into a body lumen of a patient, the delivery device comprising:

a handle assembly having a lengthwise axis and comprising:
a proximal handle portion defining a rounded triangular cross-sectional shape;
a distal handle portion defining a circular cross-sectional shape, a first circumferential wall defining a hard stop, and a second circumferential wall, a circumferential channel disposed between the first and second circumferential walls;
a first follower disposed in the circumferential channel, the first follower rotatable about the distal handle body and defining a first follower body and a first follower lug having a first follower cantilever portion with a first face and a second face, the first follower cantilever portion extending axially over the first circumferential wall such that the second face of the first follower cantilever portion is configured to contact the hard stop following rotation of the first follower;
a second follower disposed in the circumferential channel, the second follower rotatable about the distal handle body and defining a second follower body and a second follower lug having a second follower cantilever portion with a first face and a second face, the second follower cantilever portion extending axially over the first follower body such that the second face of the second follower cantilever portion is configured to contact the first face of the first follower cantilever portion following rotation of the first follower;
and
an actuator disposed over the plurality of followers and rotatable about the distal handle body, the actuator defining a follower driver extending radially inward toward the distal handle body and configured to contact the first face of the first follower of the plurality of followers such that rotation of the actuator drives rotation of the first follower of the plurality of followers;
an inner elongate member extending from the handle assembly;
and
a sheath disposed over the inner elongate member.
