Abstract

A delivery apparatus comprises a handle, a first shaft, and a second shaft. The first shaft extends through and is movable axially relative to the second shaft. The delivery apparatus comprises an inflatable balloon having a proximal end portion coupled to the second shaft and a distal end portion of the balloon coupled to the first shaft. An inflation hub assembly comprises an inflation manifold and a piston, wherein the inflation manifold comprises a main body defining a main lumen and an inflation port defining an inflation port lumen. The piston extends into the main lumen and is slidable relative to the inflation manifold. A proximal end portion of the first shaft is coupled to the piston. The piston is moveable relative to the inflation manifold in proximal and distal directions to produce movement of the first shaft and adjust the length of the balloon.

Claims19

Dependent claims

A delivery apparatus for an implantable prosthetic device, the delivery apparatus comprising:

a handle;
a first shaft extending distally from the handle;
a second shaft extending distally from the handle, wherein the first shaft extends through the second shaft and is movable axially relative to the second shaft;
an inflatable balloon having a proximal end portion and a distal end portion, wherein the proximal end portion of the balloon is coupled to a distal end portion of the second shaft and the distal end portion of the balloon is coupled to a distal end portion of the first shaft;
and
an inflation hub assembly comprising an inflation manifold and a piston, wherein the inflation manifold comprises a main body defining a main lumen extending therethrough and an inflation port defining an inflation port lumen in fluid communication with the main lumen, wherein the piston extends into the main lumen and is slidable relative to the inflation manifold;
wherein a proximal end portion of the first shaft is coupled to the piston and a proximal end portion of the second shaft is coupled to the main body of the inflation manifold or the handle;
wherein the piston is moveable relative to the inflation manifold in proximal and distal directions such that distal movement of the piston produces distal movement of the first shaft relative to the second shaft, which increases the length of the balloon, and such that proximal movement of the piston produces proximal movement of the first shaft relative to the second shaft, which decreases the length of the balloon.

a handle;
a first shaft extending distally from the handle;
a second shaft extending distally from the handle, wherein the first shaft extends through the second shaft and is movable axially relative to the second shaft in proximal and distal directions;
and
an inflatable balloon having a proximal end portion and a distal end portion, wherein the proximal end portion of the balloon is coupled to a distal end portion of the second shaft and the distal end portion of the balloon is coupled to a distal end portion of the first shaft;
wherein distal movement of the first shaft relative to the second shaft moves the distal end portion of the balloon away from the proximal end portion of the balloon to increase a length of the balloon and proximal movement of the first shaft relative to the second shaft moves the distal end portion of the balloon toward the proximal end portion of the balloon to decrease the length of the balloon;
and
a retaining mechanism configured to selectively retain the first shaft against distal and proximal movement relative to the second shaft.
