Title:
物品を移植する方法、システムおよびキット
Document Type and Number:
Japanese Patent JP4746182
Kind Code:
B2
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.
