A method and apparatus for safer and more effective deep trans-cervical intra-uterine artificial insemination (AI) is provided. Such a deep AI catheter causes minimal discomfort and risk of trauma, and does not require the services of a highly trained AI professional. First, a catheter is inserted into the cervical tract of the animal. A membrane, initially positioned inside a tube section of the catheter, is then extended from an opening in the tube and into the tract under pressure. The membrane extends into the tract without friction thereby reducing the discomfort and the risk of trauma or injury to the animal. When the membrane is fully extended into the tract, pressure causes the tip of the membrane to open thereby releasing the AI fluid and depositing the genetic material suspended in the fluid into the reproductive tract. In addition to AI and embryo transplant, other applications for the pathway include other therapeutic, diagnostic or procedures, such as introducing fluoroscopic cameras, instruments, and drug delivery.

When the membrane is fully extended into the tract, pressure causes the tip of the membrane to open thereby releasing the AI fluid and depositing the genetic material suspended in the fluid into the reproductive tract. Deployment of the membrane is facilitated by tapering its wall thickness towards its tip. In addition to AI and embryo transplant, other applications for the pathway include therapeutic, diagnostic, or other procedures such as introducing fluoroscopic cameras, instruments, and drug delivery.

Apparatus for creating a pathway in an animal and methods therefor

A biocompatible, biodegradable, bioerodible composite polymer matrix comprising interleukin-2 in an appropriate polymer. The polymer may be a polymer or copolymer of lactic acid, lactide, glycolide, glutamic acid, or it may be collagen or albumin. The material contains from 10.sup.2 to 10.sup.8 U IL-2/g of polymer. Also disclosed is a method for making the composite polyer matrix and a method for implanting the material. A soft, malleable controlled-release composite material may be used for intracranial or other implantation and may be shaped or molded to fit the site from which malignant tissue has been removed, opposing the residual tumor, complementing hemostasis, compatible with anatomical structure, and functioning as an implantable immunotherapeutic adjuvant.
