Device Facilitates Endoscopic Lithotripsy Procedures.

"The Accordion Stone Management Device combines the benefits of a device for blocking stone migration with a basket for removing stone fragments," said Richard David M.D., Associate Clinical Professor of Urology, David Geffen School of Medicine, University of California, Los Angeles. "Most importantly, it is easy to deploy even around large fragments, eliminating the challenges that occur when a fragment cannot be released from a basket. For these reasons, the Accordion is a valuable new tool with potential for routine use in lithotripsy procedures." The key feature of the Accordion device is a multi-fold film occlusion that is deployed at its distal end. Once formed, the film occlusion conforms to and fills the ureter in order to prevent retrograde migration of stone fragments into the kidney. During stone fragmentation, the Accordion device facilitates distal rinsing of smaller fragments to keep the field of view clear. Following fragmentation, the device can easily sweep larger fragments into the bladder or a ureteral access sheath, thereby eliminating tedious and time-consuming serial basketing of individual fragments. The robust occlusion film is able to withstand inadvertent contact with holmium laser and intracorporeal lithotripter energy. The Accordion device is easy to place due to a hydrophilic coating that allows it to track past the stone like a guidewire. In addition, the device features radiopaque markers that enable monitoring of advancement and deployment using fluoroscopic visualization. When required, the Accordion device's telescoping design enables the film occlusion to release easily from intact stones and large fragments. About PercSys Percutaneous Systems, Inc. learn more

Endoscopic Carpal Tunnel Surgery for Carpal Tunnel Syndrome

The pain and numbness may go away right after surgery, or it may take several months. Try to avoid heavy use of your hand for a couple of weeks. How soon you can return to work depends on whether your dominant hand (the hand used most, such as the right hand if you are right-handed) was involved, on your work activities, and on the effort that you put into rehabilitative physical therapy. If you have surgery on your nondominant hand and don't do repetitive, high-risk activities at work, you may be able to return to work within 1 to 2 days. If you have surgery on your dominant hand and do repetitive activities at work, you may require 4 or more weeks for recovery. Physical therapy may speed recovery. Why It Is Done Endoscopic carpal tunnel release surgery is considered when: You still have symptoms after a long period of nonsurgical treatment. In general, surgery is not considered until after several weeks to months of nonsurgical treatment. But this assumes that you are having ongoing symptoms but no sign of nerve damage . Nerve damage would make surgery more urgent. Severe symptoms (such as persistent loss of feeling or coordination in the fingers or hand, or no strength in the thumb) restrict your normal daily activities. There is damage to the median nerve (shown by nerve test results and loss of hand or finger function) or a risk of damage to the nerve. A person who is having surgery on both wrists, or who depends on a wheelchair, a walker, or crutches, may choose endoscopic surgery because the healing time can be shorter than with open surgery. How Well It Works Most people who have surgery for carpal tunnel syndrome have fewer or no symptoms of pain and numbness in their hand after surgery. this page
