IMPLANT DELIVERY DEVICE AND METHOD
First Claim
1. A delivery device suitable for implanting a medical implant into a cavity comprising:
- (i) a barrel defining a bore and having a proximal end and a distal end, and(ii) a plunger within the bore and being in slidable relationship with the barrel, characterised in that the delivery device further comprises;
(iii) implant contacting means positioned within the bore to hold an implant,wherein, in use the implant contacting means is adapted to limit longitudinal deformation of an implant as it travels through the bore by eliminating, or reducing the duration of, direct contact between the plunger and the implant.

Abstract
An implant delivery device (10) comprises a barrel (20), a plunger (30) and an inner sleeve (130) which comprises material stress means (140). The plunger is adapted to fit into a central bore of the inner sleeve in a sliding relationship and the inner sleeve in turn is adapted to fit into the bore of the barrel also in a sliding relationship. An alternative embodiment of the device generally comprises a barrel (20) and plunger (30) and an implant (100) loaded within the barrel, and a column of liquid (110) located proximally behind the implant. A user depressing plunger exerts a compression force on liquid, which is transferred onto the implant and the implant moves distally along the barrel toward the distal end (50).
