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.

Methods, systems, and kits for implanting articles

Devices and methods for providing access to a body cavity without substantial loss of inflation gas therein. The device comprises an access assembly 10 that may have a tubular member 12, at least one sleeve 16 coaxially disposed over the tubular member, a pneumostasis valve 13 attached to the tubular member, and an obturator 11 removably received in the tubular member. Sleeve 16 comprises expandable region 19 capable of forming an anchor 30 upon axial compression. A method to provide access using assembly 10 comprises insertion of the assembly 10 into the body cavity, expanding region 19, and insufflating the cavity with gas. Expandable region 19 on assembly 10 is axially compressed to form anchor 30 to seal against an interior wall of the body cavity. The method may further comprise either a second expanded anchor 50 or a non-expanding anchor 40 which clamps against an exterior wall of the body cavity to securely position and seal the access assembly 10.

Device and method for accessing a body cavity

Methods and systems for introducing articles and surgical instruments to target body cavities utilize conformable sleeves which are percutaneously positioned within the cavity. Articles may then be passed directly through the conformable sleeve, without use of a rigid cannula, either by pushing the articles inwardly through the sleeve using an introducer or pulling the articles inwardly through the sleeve using a tapered carrier. Surgical instruments are also passed directly inwardly through the sleeve. Such systems and methods may be used in a variety of minimally invasive surgical procedures.

Method and apparatus employing conformable sleeve for providing

An improved flashing unit for use in weatherproofing a roof penetration including complimentary mating half portions of generally regid, high-strength sheet material, each half portion comprising a base plate, a generally semi-cylindrical stack portion attached to and extending upwardly from the base plate, each base plate having an upwardly directed generally semi-cylindrical flanged edge disposed within the lower end of each semi-cylindrical stack portion, a longitudinal edge portion of each stack portion forming an elongated continuous channel for receipt of a corresponding smooth longitudinal edge of the opposite stack portion for snap-fit frictional retention of the two stack portions when mated with the edge portions of the base plates in abutment, lap plates attached to abutting edge portions of the base plates to be received in lapping relation with an abutting side edge portion of the opposing base plate, and a generally cylindrical counterflashing, or cap, for surrounding a roof penetration and receiving the upper end portion of the mated stack portions in radially inwardly spaced relation therefrom. The flashing unit may also serve as a roof vent.
