METHODS, SYSTEMS, AND KITS FOR IMPLANTING ARTICLES
First Claim
1. A system for implanting an article into solid tissue comprising:
- a needle;
a radially expandable sleeve including a lumen extending therethrough configured and dimensioned to receive the needle;
a tubular cannula configured and dimensioned for insertion through the lumen of the sleeve, the cannula including a non-collapsible lumen extending therethrough;
a dilator configured and dimensioned for insertion through the lumen of the cannula; and
at least one pharmaceutical implant having peripheral dimensions permitting the at least one pharmaceutical implant to be delivered into the tissue through the lumen of the cannula.

Abstract
Methods, systems, and kits for subcutaneously implanting articles, such as drug inserts and reservoirs. The methods rely on percutaneously forming a tissue tract and radially dilating the tract to a diameter which permits introduction of the article. By fully expanding the lumenal diameter of the tissue tract prior to introduction of the article, damage to the article resulting from passage through a partially expanded tissue tract can be avoided. In the exemplary embodiment, a radially expandable sleeve is first percutaneously introduced to the subcutaneous target site. An assembly of a cannula and dilator is then passed through the sleeve, effecting radial expansion. The dilator is removed and the article is then introduced through a lumen of the cannula.

17. A method for implanting an article within solid tissue, the method comprising the steps of:
-
inserting an assembly of a needle and a radially expandable sleeve into the tissue; then withdrawing the needle from the sleeve; then inserting an assembly of a cannula and a dilator into the sleeve such that a distal-most end of the cannula reaches a target site in the tissue and extends beyond a distal-most end of the sleeve, and a distal-most end of the dilator extends beyond a distal-most end of the cannula; then withdrawing the dilator from the cannula to reveal an opening in the tissue positioned adjacent the distal-most end of the cannula; then advancing the article through the lumen of the cannula; and then depositing the article within the opening in the tissue. - View Dependent Claims (18, 19, 20)
