Abstract

A male contraception apparatus includes a tube configured for insertion into the seminal duct. The tube has a hollow portion open at both ends. Positioned within the hollow portion is at least one filter. The filter includes a plurality of microchannels that extend through the filter and a plurality of nanospikes formed on one surface.

First claim

The invention claimed is:

1 . A male contraceptive device comprising: a tube having an internal hollow whose both ends are open and insertable into an ejaculatory duct; and at least one filter located in the hollow of the tube, wherein the at least one filter comprises a plurality of microchannels passing therethrough and a plurality of nanospikes formed on a first surface thereof.

2 . The male contraceptive device according to claim 1 , wherein the male contraceptive device comprises a plurality of pressing members arranged on an outer surface of the tube and spaced apart from each other.

3 . The male contraceptive device according to claim 2 , wherein the tube further comprises a partition wall located in the hollow to partition the hollow into an inner space and an outer space and a plurality of second through-holes penetrating an inner surface in contact with the outer space and the outer surface, and the outer space is located outside the inner space to surround the inner space.

4 . The male contraceptive device according to claim 3 , wherein each of the pressing members comprises a second pressing portion having a second accommodation space therein and a second connection portion connecting the second pressing portion and the tube and having a second connection hole through which a corresponding second through-hole is in communication with the second accommodation space.

5 . The male contraceptive device according to claim 2 , wherein the tube further comprises a plurality of first through-holes penetrating an inner surface thereof in contact with the hollow and the outer surface thereof and each of the pressing members comprises a first pressing portion having a first accommodation space therein and a first connection portion connecting the first pressing portion and the tube and having a first connection hole through which a corresponding first through-hole is in communication with the first accommodation space.

6 . The male contraceptive device according to claim 2 , wherein the pressing members are arranged at regular intervals along a circumference of the tube.

7 . The male contraceptive device according to claim 1 , further comprising a movement-preventing member located at one side of the tube and surrounding the tube, wherein the movement-preventing member is made of a material that expands at a preset temperature.

8 . The male contraceptive device according to claim 1 , wherein the tube is made of a stretchable material.

9 . The male contraceptive device according to claim 1 , wherein the at least one filter is provided in plurality and the plurality of filters are arranged along a lengthwise direction of the tube.

10 . The male contraceptive device according to claim 1 , wherein the tube further comprises a flange member protruding from an inner surface to support a second surface of the at least one filter.
