Casmed- Double Lumen Follicle Aspiration Set,
Single Lumen Follicle Aspiration Set with Side Arm,
Embryo Transfer Catheter (Standard)

Double Lumen Follicle Aspiration Set

Designed for transvaginal aspiration of follicles to obtain oocytes. The set includes needle with tubing and bung for connection to a standard test tube. This needle allows continuous aspiration and flushing of the follicle thereby reducing operating time. All needles have echogenic markings for easy recognition under ultrasound.

Materials: The needle and its connections are all manufactured from high grade surgical stainless steel. The tubing to the collection tube is manufactured from translucent F.E.P. Both the needle and tubing are available in different lengths and gauges.

• Sterilization: Steam sterilized and designed for single use only.
• Testing: All materials are tested to mouse embryo blastocyst survival to ensure a nontoxic, sterile product.
• This needle is available in both 15 and 16 gauges.
• All products are manufactured in accordance with quality standards ISO 9001-2000, ISO 13485 and CE marking.

Single Lumen Follicle Aspiration Set with Side Arm

Designed for transvaginal aspiration of follicles to obtain oocytes. The set includes needle with tubing and bung for connection to a standard test tube. This needle also incorporates a side arm to facilitate flushing if required. All needles have echogenic markings for easy recognition under ultrasound.

Materials: The needle and its connections are all manufactured from high grade surgical stainless steel. The tubing to the collection tube is manufactured from translucent F.E.P. Both the needle and tubing are available in different lengths and gauges.

• Sterilization: Steam sterilized and designed for single use only.
• Testing: All materials are tested to mouse embryo blastocyst survival to ensure a nontoxic, sterile product.
• Standard needle is 17 gauge x 31 cm with 60 cm tubing – Order code SCSB. Also available in other gauges or lengths, please state when ordering.
• All products are manufactured in accordance with quality standards ISO 9001-2000, ISO 13485 and CE marking.

Embryo Transfer Catheter (Standard)

The catheter tip is rounded and smooth for non-traumatic access. The outer sheath and catheter are marked with 1cm graduations to indicate degree of advancement.

• Materials: Catheter made from ultra soft non-embryo toxic polyurethane.
• Testing: All materials are tested to mouse embryo blastocyst survival to ensure a nontoxic, sterile product.
• All products are manufactured in accordance with quality standards ISO 9001-2000, ISO 13485 and CE marking.

Proposed Directions

This totally novel design ensures an easy access through the cervical canal yet, with an extremely soft smooth-ended catheter, minimizes the risk of damage to the wall of the uterus of the fundus. Avoiding such trauma is critical to the successful implantation of the embryo.

1. The device consists of a dual lumen catheter. The first lumen has a closed rounded tip and carries a stainless steel stylet which is malleable to allow for bending to a predetermined shape (from previous examinations of the route through the cervical canal). The stylet provides sufficient rigidity to ease the passage through the canal.
2. The other lumen is open-ended but still extremely smooth. The stiffness provided by the stylet also makes the loading of the embryo(s) easier under the microscope. Once loaded the device is inserted through the cervical canal as far as the internal os. The 1cm graduation marks from the tip of the catheter will assist in determining this point which can also be confirmed using ultra sound.
3. From the internal os the catheter only is advanced the required distance into the uterus. This can be observed by the graduations on the stylet which show the distance between the distal tips of the catheter and stylet.
4. The extreme softness of the catheter and its very smooth tip will avoid damage to the uterine wall during passage towards the fundus. It is still advisable to stop just short of the fundus, without touching it, before transferring the embryo(s).
5. This procedure ensures easy access in almost every case without the need for dilation or other devices. Coupled with the softness and smoothness of the tip, this catheter provides the least traumatic method available for transferring embryo(s).
