Abstract
The invention encompasses improved catheters comprised of multiple tubular bodies and methods of using them in artificial insemination.
Claims23
A 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 polyether block amide and
- a proximal end and a distal end, the distal end comprising an orifice formed i) in a beveled, radiused or chamfered terminus or ii) in a terminal flange comprising a beveled, radiused or chamfered edge.
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 polyether block amide and a proximal end and a distal end, the distal end comprising 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.
A catheter comprising:
- a first tubular body, a second tubular body and a third tubular body,
- the third tubular body axially and slidably extending within the first tubular body, and
- the second tubular body axially and slidably extending within the third tubular body, the third tubular body comprising a proximal end, a distal end and a deflecting element at the distal end.
