Abstract: Methods and apparatuses for peritoneal catheter placement are disclosed herein. An example method includes using a puncture device to create an access hole to a patient's peritoneal cavity. The puncture device includes a lumen that enables a guidewire to be inserted into the peritoneal cavity. The puncture device is then replaced with a catheter, which is inserted along the guidewire. A surgical seal is next applied to connect the catheter to adjacent patient muscle tissue. After the guidewire is removed, a tunneling device creates a pathway through fat tissue to anchor the catheter. An end of the tunneling device is aligned with an external piercing device to pierce the patient's skin from the outside, creating a catheter exit hole. An end of the catheter is connected to the tunneling device and pulled through the exit hole, thereby enabling the catheter to be connected to peritoneal dialysis tubing for a treatment.

Abstract: A trocar for peritoneal dialysis is disclosed herein. An example trocar includes a conduit having two or more parallel lumens and a head connected to a first end of the conduit. The head includes two (or more) parallel lumens that are aligned respectively with the parallel conduit lumens and includes at least one of a gasket or a seal for each lumen. The trocar also includes a coupler connected to the head. The coupler includes two (or more) parallel lumens that are aligned respectively with the parallel lumens of the head. The coupler includes a coupling mechanism for each lumen for securing surgical tools in place after insertion into a patient. The trocar may also include an obturator having a shaft that is removably inserted through the coupler, head, and conduit to protrude from a second end of the conduit.
