Devices and methods for artificial insemination

A method of depositing or collecting a fluid, an embryo or gametes using a catheter, the catheter comprising a first tubular body, a cervical anchor connected to an outer surface of the first tubular body, and a second tubular body axially and slidably extending within the first tubular body, the second tubular body comprising a lumen, a polyether block amide and a proximal end and a distal end, the distal end comprising a u-shaped portion, wherein the u-shaped portion serves to bend the distal end of the lumen of the second tubular body back in the direction of the proximal end of the second tubular body, and an orifice formed i) in a beveled, radiused or chamfered terminus or ii) in a terminal flange comprising a beveled, radiused or chamfered edge, the method comprising:

• inserting the first tubular body into a sow's vagina;
• advancing the first tubular body into the sow's cervical canal so that the cervical anchor is seated against the cervical canal;
• advancing the second tubular body axially within the first tubular body, past the sow's cervix;
• and
• applying positive or negative pressure within the second tubular body.
