Implant delivery device
First Claim
1. An implant delivery device comprising:
- a first shaft having a proximal portion and a distal portion, the first shaft having an outer surface and an inner surface defining a first lumen along a longitudinal axis, the distal portion having a tip defining a taper in the distal direction toward the longitudinal axis and terminating at a distal opening;
a second shaft having a proximal portion and a distal portion and an inner surface defining a second lumen therebetween having a first cross-section, the second shaft disposed within the first lumen such that the second lumen is generally coaxial with the first lumen to define a chamber, the distal portion of the second shaft terminating in a port having an opening in communication with the distal opening of the first shaft, the opening of the port having a second cross-section greater than the first cross-section.

Abstract
An implant delivery device preferably includes a first shaft having a proximal portion and a distal portion. The first shaft includes an outer surface and an inner surface defining a first lumen along a longitudinal axis. The distal portion includes a tip defining a taper in the distal direction toward the longitudinal axis and terminating at a distal opening. The device also includes a second shaft having a proximal portion and a distal portion and an inner surface defining a second lumen therebetween having a first cross-section. The second shaft is disposed within the first lumen such that the second lumen is generally coaxial with the first lumen to define a chamber. The distal portion of the second shaft terminates in a port having an opening in communication with the distal opening of the first shaft. The port preferably includes a second cross-section greater than the first cross-section.

22. An implant delivery device comprising:
-
an inner shaft having a first diameter extending between a proximal end and a distal end spaced apart along a longitudinal axis, the inner shaft terminating in a port having a second diameter greater than the first diameter; and an outer sheath disposed about the inner shaft, the outer sheath terminating in a distal tip tapering toward the longitudinal axis, the outer sheath being movable along the longitudinal axis in a proximal direction relative to the inner shaft to expose the port, the outer sheath having a layer including a proximal portion, a distal portion, and at least one intermediate portion therebetween, the proximal, distal and at least one intermediate portions being discrete portions along the longitudinal axis, each having a discrete durometer. - View Dependent Claims (23, 24)
