PVDF to Detect and Autonomously Prevent Slip During Retraction in Laparoscopic Surgery
Objective During laparoscopic surgery tissue retraction is necessary for exposure of the operating field. Currently this is performed manually by grasping the tissue in laparoscopic forceps but could be performed automatically with an appropriate device. This would need to automatically detect when tissue is slipping from its grasp and react appropriately. Method Polyvinylidene fluoride (PVDF), a piezoelectric… Continue Reading
DDES™ Flexible Single Incision Operating Platform Facilitates an Extended Thoracic Lymphadenectomy via a Trans-hiatal Approach.
Objective:Emphasis on extended lymph node dissection during esophagectomy is increasing. Many propose that the best technique to achieve this goal is to approach the mediastinal portion of the operation trans-thoracically. However, this may increase overall surgical morbidity compared to a purely transhiatal technique. Totally laparoscopic transhiatal esophagectomies have been performed but while better than open,… Continue Reading
Sumotm System Facilitates Mucosotomy and Submucosal Tunnel Creation for Per-oral Esophageal Myotomy (POEM)
Objective:The POEM procedure for achalasia is a complex therapeutic flexible endoscopic technique, requiring extensive practice to learn. Initial experience with the POEM demonstrates that it has the potential to become the therapeutic procedure of choice in the future. However, in order for this to be achieved, the procedure needs to be simple, safe and easily… Continue Reading

A Modified Buess Rectoscope for TEM
Objective of the technology. TEM (Transanal Endoscopic Microsurgery) is a minimally invasive endoscopic technique, which offers excellent access and visualization of the surgical field, improving the quality of local excision for rectal lesions with full-thickness excision of the rectal wall. We have modified the Buess rectoscope in order to improve the quality and versatility of… Continue Reading
Modified Circular Stapler for Laparoscopic Intracorporeal Colorectal Anastomoses
Objective of the device. During standard colorectal laparoscopic resection, in order to insert the anvil with the purse-string technique, anastomosis is performed by extracting the left colon through a small laparotomy. Intracorporeal colon anastomosis avoids extensive and unnecessary colon mobilisation, but is considered technically challenging. During intracorporeal colorectal anastomoses with the circular stapler, the anvil… Continue Reading
Concurrent Limited Incision Ileostomy Reversal and Cholecystectomy via Flexible Laparoscopic Platform
Introduction: The trend towards minimally invasive procedures has progressed rapidly over the past several decades. Novel techniques and new technologies are constantly being introduced to perform increasingly complex procedures through very limited incisions. Utilization of an ostomy site for laparoscopic colorectal surgery has been described. We performed a cholecystectomy and ileorectal anastamosis (IRA) through an… Continue Reading
Clinical Experience With a Hands-free Internal Liver Retractor in Laparoscopic Bariatric Surgery
<Objective>Endolift (Virtual ports, Richmond, VA) is a new liver retracting device. It is characterized by an internal and hands-free retractor, which does not require an additional port and anchoring to any external device that limits the patient’s position and adds clutter to the operating table. It also enables us to get comparable or better exposure… Continue Reading
Accurate High-intensity Focused Ultrasound Ablation in a Porcine Liver Model Through Integration of Real-Time Image Guidance, Robotic Navigation, and Elastographic Monitoring
Objective Active research into accurate, minimally-invasive, image-guided destruction of focal hepatic malignancies will expand the population of treatable patients and potentially extend survival. Our objective is to develop an accurate, real-time monitored minimally-invasive ablation system through the integration of high-intensity focused ultrasound (HIFU) ablation within a flexible needle configuration, robotic steerable active cannula guidance, and… Continue Reading
Transanal Endoscopic Da Vinci Surgery (teds): Results of Cadaveric Experiments
Background: single port platforms and instrument are increasingly used for transanal surgery. In an effort to tackle some of the limitations and increase intraluminal flexibility, robotic integration could be a logical next step. Objective:To report on our initial experience with transanal endoscopic da Vinci surgery (TEdS) using a glove port on human cadavers. Methods: After… Continue Reading
Development of Metallic Reusable Port for Single Port Surgery: Possibility of Enhancement of Operability and Operation Cost Reduction
Single Port Surgery (SPS) has become used worldwide as a minimally invasive surgery method. However, many SPS ports are polymer-made disposable products, which could cause problems such as steep rise of medical cost or increase of management cost of medical waste, leading to environmental problems. We invented a metallic reusable port for SPS. Smooth fixing… Continue Reading
An Externally-Steerable Magnetic Levitation Surgical Camera for Multiple-Point-of-View Laparoscopy
1. Objective of the technology or deviceThe intended purpose of our device, the Magnetic Internal Mechanism (MIM) camera, is to overcome the ergonomic constraints of laparoscopic surgery and in particular of single port laparoscopy (SPL) by providing a new wired miniature surgical camera with a novel magnetic levitation system. By this innovative approach the number… Continue Reading
Transabdominal Endoscopic Pericardial Access for Epicardial Ablation
Epicardial cardiac ablation (MAZE procedure) and endocardial (percutaneous catheter based) ablation are well described techniques in the treatment of atrial fibrillation. A novel procedure recently developed is the hybrid mini-maze (convergent MAZE procedure) that involves a concurrent transabdominal endoscopic epicardial MAZE and endocardial catheter based ablation. The MAZE procedure has classically involved either a sternotomy… Continue Reading
Leveraging Mobile Health Technology in a Model for Home-based Primary Care: a Demonstration Project
