Chemo port implantation has enhanced the quality of life for cancer patients. Interventional radiologists or surgeons may implant chemo ports via Internal Jugular Vein (IJV) Subclavian (SCV). A central catheter that is implanted into venous system connected to a chamber (subcutaneous) form system. The chamber's subcutaneous position enhances patient and lower infection rate than non-totally dev...

BACKGROUND The left ventricular (LV) lead local electrogram (EGM) delay from the beginning of the QRS complex (QLV) is considered a strong predictor of response to cardiac resynchronization therapy. We have developed a method for fast epicardial QLV mapping during video-thoracoscopic surgery to guide LV lead placement. METHODS A three-port, video-thoracoscopic approach was used for LV free wa...

OBJECTIVES To evaluate the long-term functional and hemodynamic effects of right ventricular outflow tract (RVOT) pacing by comparison with right ventricular apical (RVA) pacing. BACKGROUND Acute studies have suggested that RVOT pacing could significantly improve cardiac performance in comparison with RVA pacing but no data are available in chronically implanted patients. METHODS Sixteen pa...

External beam radiation therapy (RT) is often offered to breast cancer patients after surgical mastectomy followed by breast reconstruction with silicone implants. In some cases, the RT is administered while the patient is still implanted with a temporary tissue expander including a high-density metallic port, which is expected to affect the planned dose distribution. This work uses Monte Carlo...

BACKGROUND Tissue expanders are devices which are used to create enough skin to form suitable flap in restoration of great skin deficiencies which are not modified initially. The current study aimed at investigating the patients' satisfaction and the complications such as rupture, hematoma, wound infection, seroma, leakage, chronic pain, and expander expose of internal (implanted under the skin...

The introduction of new imaging techniques has markedly improved the diagnosis of hepatobiliary disorders. Due to their anatomic situation, a substantial percentage of malignancies located near the hilus is not suitable for surgical management. We discuss an effective palliative intervention to relieve jaundice. In many instances drainage is a superior choice when biliodigestive anastomoses are...

BACKGROUND AND OBJECTIVES To remove a foreign body from the peritoneal cavity in laparoscopic surgery, 2 or 3 ports are usually used. We have recently performed such a removal using a single 10-mm transumbilical port, a 0-degree laparoscope, a Farabeuf retractor, and a laparoscopic grasping forceps. METHODS Two patients with ventriculoperitoneal shunt catheter (V-P shunt) were admitted to our...

OBJECTIVE We aimed to evaluate the effectiveness of subcutaneously implanted epidural ports (SIEP) in the management of patients with advanced-stage gynecologic cancer-related severe chronic pain who do not respond to intravenous tramadol infusion, transdermal fentanyl, and oral morphine administration or who cannot tolerate the unacceptable and unmanageable side effects of these drugs. METHO...

OBJECTIVE To evaluate the fixation strength and tissue reaction of the glue fixation and self-stabilizing leg fixation methods and to compare the results with those of the conventional tagging suture fixation method. MATERIALS AND METHODS Twelve healthy rabbits were selected and three different methods of implanting the port chamber were employed on the back of each rabbit. A total of thirty ...

Sensors implanted inside a body compose so called intra body networks (IBNs), which promise high degree of mobility, remote diagnostic accuracy, and the potential of directly activating the action of drug delivery actuators. To enable communication among these implanted sensors, we use the concept of galvanic coupling, in which extremely low energy electrical signals are coupled into the human ...
