Abstract

Abstract A presterilized, packaged, subcutaneous contraception kit including a simple, disposable cutter device (1) which makes precise, repeatable less than 5 mm incisions in the skin which is capable of being used by nonskilled personnel. The contraceptive steroid delivery systems are preloaded in a disposable flexible plastic carrier (30) which is used to blunt disect under the skin where the capsules (52) are deposited by the operation of drawing the carrier (30) back over a rod (42) which is held relatively stationary. The carrier (30) stops automatically when one capsule has been deposited and must be triggered in order to deposit the next capsule.

Claim 8
Dependent Claim 13 words
The apparatus of claim 3 wherein the insertion means is made of plastic.
Claim 9
Dependent Claim 201 words
A kit for subcutaneously placing a medicinal implant beneath the skin, comprising: cutter means for making an incision of a controlled length and depth in the skin; an implanter for inserting the implant through the incision and for locating the implant beneath the surface of the skin and having a bore within which the implant is initially contained, including; a hollow main body portion forming a first part of the bore; and insertion means, connected to the main body portion to form a second part of the bore and adapted to be inserted through the incision and beneath the skin, including: means for blunt dissecting cutaneous tissues when inserted beneath the skin through said incision: and a long, hollow, needle-like means which is flexible along its entire length, for flexibly connecting the hollow main body portion to the blunt dissecting means so that the insertion means may flex along its entire length when inserted through said incision; and manually-activated means, located within the bore and operable when the insertion means has been inserted through an incision, for ejecting an implant out from the main body portion through said insertion means and into a location under the surface of the person's skin.
Claim 10
Dependent Claim 201 words
A kit for subcutaneously placing a medicinal implant beneath the skin, comprising: cutter means for making an incision of a controlled length and depth in the skin; an implanter for inserting the implant through the incision and for locating the implant beneath the surface of the skin and having a bore within which the implant is initially contained, including; a hollow main body portion forming a first part of the bore; and insertion means, connected to the main body portion to form a second part of the bore and adapted to be inserted through the incision and beneath the skin, including: means for blunt dissecting cutaneous tissues when inserted beneath the skin through said incision: and a long, hollow, needle-like means which is flexible along its entire length, for flexibly connecting the hollow main body portion to the blunt dissecting means so that the insertion means may flex along its entire length when inserted through said incision; and manually-activated means, located within the bore and operable when the insertion means has been inserted through an incision, for ejecting an implant out from the main body portion through said insertion means and into a location under the surface of the person's skin.
