Disclosed herein are exemplary medical devices for controlled delivery of material compositions, particularly occlusive, therapeutic, or diagnostic compositions.

The present invention comprises systems, methods and devices for the delivery of compositions for occluding or of means for opening conduits. The implantable occlusive material may be delivered pre-formed or in situ cured and, may be a resorbable material that supports tissue ingrowth that eventually replaces the material leaving little or no original material in place. The delivery system is positioned to allow for placement of the occlusive material into the body conduit. Use of delivery systems, methods and devices for re-opening an occluded body conduit are also included.

Methods and devices for treating and occluding a female patient's fallopian tubes to provide permanent or extended birth control or sterilization.

A fallopian biocompatible plug can include differently expandable portions. A method of treating a uterine abnormality of a patient includes: providing an endoscope having a working channel; inflating a uterine cavity with a fluid; delivering a biocompatible plug into an ostium of a fallopian tube of the patient, wherein the biocompatible plug is substantially cylindrical in form and configured to be radially expandable, wherein the biocompatible plug is configured to expand in the ostium of the fallopian tube to seal the fallopian tube from the uterine cavity; delivering a resection device through the working channel; and resecting the uterine abnormality.
