SWAN NECK™ Presternal Peritoneal Catheters

SWAN NECK™ Presternal Peritoneal Catheters are differentiated from other catheters by the presternal (upper) segment of this catheter that is tunneled into the subcutaneous tissue of the chest wall. The upper segment connects with the intraperitoneal (lower) segment by a double-barbed titanium connector. Both the presternal and intraperitoneal segments can be trimmed in order to custom fit the patient. The intraperitoneal segment is a variation of the Missouri catheter. The pre-formed 180° angle is designed to keep both the internal and external portions of the catheter positioned downward. They are intended to keep the internal portion from migrating out of position and to decrease stress on the exit site by the external portion, which often occurs when a straight catheter is manually curved during placement. The SWAN NECK™ Presternal Peritoneal Catheter is indicated for patients with a more active lifestyle. As the exit site is located on the upper chest wall instead of at the belt line, this catheter is ideal for those patients who enjoy wading in a pool or soaking in a tub. This catheter is also ideal for obese patients who may have difficulty manipulating a catheter at the belt line and incontinent patients.

Frequently Asked Questions

Question Answer
WHAT IS THE FRENCH SIZE OF THE SWAN NECK™ PRESTERNAL CATHETERS? The SWAN NECK™ Presternal Catheters are 15Fr. in outer diameter.
WHAT IS THE INNER DIAMETER OF THE SWAN NECK™ PRESTERNAL CATHETERS? The inner diameter of the SWAN NECK™ Presternal Catheters is 2.6 mm or 8Fr.
WHAT MATERIAL COMPRISES THE SWAN NECK™ PRESTERNAL CATHETERS? The SWAN NECK™ Presternal Catheters are comprised of a highly kink-resistant, biocompatible silicone that provides comfort for the patient by reducing the likelihood of skin abrasion at the exit site and not impeding patient mobility. The silicone also reduces the risk of organ or intestinal damage during insertion and use.
WHAT FUNCTION DOES THE PRESTERNAL (UPPER) SEGMENT SERVE ON THE SWAN NECK™ PRESTERNAL CATHETERS? The SWAN NECK™ Presternal Catheter is indicated for patients with a more active lifestyle. The presternal (upper) segment allows the exit site to be located on the upper chest wall instead of at the belt line, this catheter is ideal for those patients who enjoy wading in a pool or soaking in a tub. Also ideal for obese patients who may have difficulty manipulating a catheter at the belt line as well as incontinent patients.
WHAT FUNCTION DOES THE SWAN NECK™ SERVE ON THE SWAN NECK™ PRESTERNAL CATHETERS? The SWAN NECK™ portion of the SWAN NECK™ Presternal Catheters serves three main functions: - Directs the internal portion of the catheter downward and keeps it from migrating out of position - Decreases stress on the exit site - Positions the external portion of the catheter downward, preventing debris from collecting at the exit site.
WHAT FUNCTION DOES THE SILICONE BEAD SERVE ON THE SWAN NECK™ PRESTERNAL CATHETERS? The silicone bead on the SWAN NECK™ Presternal Catheter rests just inside the peritoneum and is designed to prevent dialysate leakage.
WHAT FUNCTION DOES THE FELT DISK SERVE ON THE SWAN NECK™ PRESTERNAL CATHETERS? The felt disk on the SWAN NECK™ Presternal Catheter is placed just outside the peritoneum and is sutured to the rectus muscle. Fibroblasts grow into the fibers of the felt cuff to anchor the catheter. A second cuff in the subcutaneous tissue is designed to seal the exit site, helping to prevent bacteria from entering into the catheter tract.
CAN THE SWAN NECK™ PRESTERNAL CATHETERS BE PLACED VIA A MODIFIED SELDINGER TECHNIQUE OR LAPAROSCOPICALLY? No. The SWAN NECK™ Presternal Catheters can not be placed via a modified Seldinger technique or laparoscopically due to the Missouri beaded flange on this catheter design. An open insertion technique is recommended for this catheter. Please refer to the product's Instructions for Use (IFU) for additional information for implanting a peritoneal catheter by the open method.
HOW MANY CUFFS DO THE SWAN NECK™ PRESTERNAL CATHETERS HAVE? The SWAN NECK™ Presternal Catheter design has three (3) cuffs, a preperitoneal or deep felt disc and two (2) subcutaneous cuffs in the chest. The advent of three (3) cuffs in this design has been shown to greatly reduce the occurrence of infections when compared to standard abdominal peritoneal dialysis catheters. According to the product’s Instructions for Use, the preperitoneal disc is anchored to the anterior rectus sheath making a watertight seal to prevent leakage from the peritoneal cavity. The subcutaneous cuffs are placed at the second or third intercostal space and 3cm from the catheter exit site in the presternal or parasternal area to avoid cuff infection or extrusion. The cuffs serve to anchor the catheter via tissue ingrowth and serve as a barrier to infection.
WHEN WOULD I CHOOSE TO PLACE A SWAN NECK™ PRESTERNAL CATHETER VS. A NON-PRESTERNAL SWAN NECK™ CATHETER? The SWAN NECK™ Presternal Catheter is indicated for patients with a more active lifestyle, obese patients who may have difficulty manipulating a catheter at the belt line, or incontinent patients.
WHERE SHOULD THE EXIT SITE BE LOCATED WHEN PLACING THE SWAN NECK™ PRESTERNAL CATHETERS? According to the products Instructions for Use, to ensure catheter tip position is in the true pelvis, the position of the abdominal cuff should be above the umbilicus in small persons and at the level of or slightly below the umbilicus in tall persons. On the chest, a superficial cuff is marked at the second or third intercostal space and 3cm from the catheter exit site in the presternal or parasternal area. Caution: Take care to avoid an exit site that would interfere with undergarments in women and avoid the midline in patients likely to have open heart surgery. Please refer to the product's Instructions for Use (IFU) for additional information.
HOW DO YOU CALCULATE THE PRIMING VOLUME OF THE SWAN NECK™ PRESTERNAL CATHETERS? To determine the priming volume of the SWAN NECK™ Presternal Catheters multiply the length of the catheter in centimeters (cm) by the correction factor (0.0548 cc/cm). The result is the priming volume expressed in cc.
HOW ARE THE SWAN NECK™ PRESTERNAL CATHETERS PACKAGED? All products are supplied sterile. Products are shipped one (1) per package.
