Abstract
Abstract A percutaneous catheter introducer (PCI) is disclosed having a transparent housing, a valve seal disposed within the housing, a rotatable suture ring including a tab, and a sheath extending through the suture ring and into the housing. The transparent housing allows for detection of emboli formation inside the percutaneous catheter introducer. The rotatable suture ring permits versatility of movement when sewing the PCI device to the patient.
