First Claim
Patent Images
1. An implantable medical device for the treatment of obesity comprising:
- an access port configured to attach to body tissue;
a tube having a first end and a second end, the first end coupled to the access port; and
a needle guard assembly covering the first end of the tube, the needle guard assembly including;
a first composite guard and a second composite guard, each composite guard including an arrangement of puncture resistant members and a flexible substrate having a first side on which the puncture resistant members are positioned,the second composite guard covering the first composite guard, andthe first composite guard and the second composite guard being positioned such that the arrangement of puncture resistant members of the second composite guard is misaligned with the arrangement of puncture resistant members of the first composite guard.
