Abstract

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.

Dependent claims

A medical device for use with assembly comprising an endoscope having a working channel and a delivery tube configured to be received in the working channel, the device, comprising:

a substantially cylindrical plug configured to be deliverable through a uterine cavity and into a fallopian tube of a patient by way of the delivery tube, the plug including a substantially cylindrical mandrel flexible in a longitudinal direction, a nose portion comprising a closed forward end and a substantially cylindrical member, and at least one body portion comprising a ring member having a forward end arranged against a rearward end of the nose portion, the nose portion and the at least one body portion mounted on an outer surface of the mandrel;
wherein the plug is configured to expand to internally seal the fallopian tube of the patient following its delivery into the fallopian tube;
wherein the flexibility of the mandrel allows the nose portion and the at least one body portion to bend out of alignment in the longitudinal direction, conforming to a curvature of the fallopian tube;
and
wherein at least one of:
a first portion of the mandrel is configured to expand relative to the nose portion to expand the rearward end of the nose portion and a second portion of the mandrel is configured to expand relative to the at least one body portion to expand a rearward end of the at least one body portion;
or
material at the rearward end of the nose portion is configured to expand more relative to material at the forward end of the nose portion, and wherein material at a rearward end of the at least one body portion is configured to expand more relative to material at the forward end of the at least one body portion.
