Randomized Trial Comparing Sphincteroplasty and Lithotripsy for Extraction of Large Bile Duct Stones

Stones in the bile duct can result in various complications including acute cholangitis, acute pancreatitis and secondary biliary cirrhosis.1 Bile duct stones should therefore be removed and this can be successfully achieved in 85-90% of patients using standard endoscopic techniques. This comprises endoscopic sphincterotomy whereby the duodenal sphincter at the ...

Phase N/A

Effects of Different Exercise Training Dose on Exercise Performance and Noninvasively Estimated Muscle Oxygen Extraction in Diabetic Postmenopausal Women

The purpose of this study is specifically to investigate (1) the exercising muscle oxygenation response in diabetic postmenopausal women; (2) the dose-response of different physical activity interventions on skeletal muscle oxygenation response; (3) the related mechanisms of training effects.

Phase N/A

Measurement of Cerebral Oxygen Extraction Fraction Using MRI Technique

All images in this study were acquired on a 1.5 T Sonata whole body scanner (Siemens Medical Inc., Erlangen, Germany) using 2D multi-echo gradient echo/spin echo sequence and 2D single-shot gradient echo-planar imaging sequence plus intravenous magnetic susceptibility contrast medium. The quantitative estimates and mapping of cerebral metabolic rate of ...

Phase N/A

EyeKon Medical Inc. Capsular Tension Ring Study

The clinical study of the CTR-10 and CTR-12 Capsular Tension Rings is to be conducted with the following objectives: 1. Determine the ability of the device to maintain the shape of the capsular bag and therefore keep the intraocular lens centered; 2. Determine post-operative visual acuity of patients receiving the ...

Phase N/A

Bridge Occlusion Balloon in Lead Extraction Procedure

This study will evaluate the use of an occlusion balloon (Bridge™ Occlusion Balloon, Spectranetics) within the Superior Vena Cava in lead extraction patients. This will be performed in a non-emergent setting to allow for evaluation of how best to integrate this new technology into the investigators clinical practice. The study ...

Phase N/A

A Comparison of Two Ab Interno Procedures in the Treatment of Glaucoma in Patients Undergoing Cataract Extraction

The purpose of this study is to compare the safety and efficacy of goniotomy performed with a novel ophthalmic knife compared to trabecular bypass stent implantation in mild to moderate glaucoma subjects who are also undergoing cataract extraction with phacoemulsification (Phaco) and posterior chamber intraocular lens (PCIOL) implant.

Phase N/A

A Clinical Assessment of the Full Range of Functional Vision With Three Tecnis Multifocal IOL 1-Piece Models in Bilateral Cataract Extraction

This will be a multi-center, parallel comparison clinical study design with two treatment groups. One hundred (100) qualified study patients will receive a +2.75D (ZKB00) Tecnis Multifocal 1-Piece IOL in their dominant eye. Of these study patients, 50 patients will receive the +3.25D (ZLB00) Tecnis Multifocal 1-Piece IOL in their ...

Phase N/A

Intra-surgical Evaluation of CATS Tonometer Prism and Abbott Medical Optics Versus Alcon Phacoemulsification Machines

This study will measure the dynamic real-time IOP in the anterior chamber during standard phacoemulsification surgery. What is known: - Fluidics control is determined to be one of the primary drivers of physician decision making in choosing phacoemulsification equipment. - Active pressure system fluidic control has a perceived and possibly ...

Phase N/A

A Comparison of Two Socket Sealing Collagen Matrices for Extraction Socket Management

A prospective, randomized, multi-center, controlled clinical study of intact extractions (bony dehiscences <1/3 socket apico-coronal and mesial-distal dimension) with delayed implant placement. Study objective: to compare extraction socket management effectiveness and office economics of a frequently used wound dressing (control) with a soft tissue augmentation matrix (test) in 32-64 subjects ...

Phase N/A

Ridge Preservation With Moldable Beta-tricalcium Phosphate Bone Substitute on Non-containable Non-Molar Extraction Sites

Purpose of the single arm study is to clinically and histologically evaluate alloplastic in-situ hardening, moldable beta-tricalcium phosphate(TCP) bone graft material and polylactide membrane in alveolar ridge preservation following extraction of non-molar teeth with non-containable extraction sockets.
