Abstract: A bipolar ablation device for treatment of a stenosis within an implanted metallic stent may include an elongate shaft slidably disposable within an endoscope, the elongate shaft including at least one electrode configured to form a first pole of the bipolar ablation device, and an electrode lead slidably disposable within the endoscope. The electrode lead may be configured to electrically engage the implanted metallic stent to form a second pole of the bipolar ablation device. The elongate shaft may be positionable within a lumen of the implanted metallic stent.

Abstract: According to one aspect, a processor device in communication with an endoscopic device obtains a spectrum image of bleeding in an upper gastrointestinal (GI) area of a patient. A filter is applied to the spectrum image to generate a pre-enhanced image. The filter enhances the spectrum image at one or more light wavelengths in the light spectrum. The pre-enhanced image is analyzed to identify an area of interest that represents a portion of the upper GI area with an active bleed. A contrast enhancement technique is applied to the area of interest in the pre-enhanced image to generate an enhanced contrast image. Spatial filters are applied to the enhanced contrast image to produce a final colorized image with defined blood vessels in the upper GI area of the patient.

Abstract: An example medical stent for treating a body lumen is disclosed. The example stent includes an expandable scaffold having a first end region, a second end region and an outer surface. The stent further includes a first fixation member coupled to the expandable scaffold and a biodegradable material disposed along the first fixation member at a first tissue engagement region. Further, the biodegradable material is designed to degrade from a first configuration in which the biodegradable material shields the first fixation member from a target tissue site to a second configuration in which the first fixation member is engaged with the target tissue site.

Abstract: Medical stent designs are disclosed. An example stent includes a tubular scaffold having a proximal end and a distal end. The tubular scaffold includes a first filament extending between the proximal end and the distal end, the first filament including a first biodegradable region positioned adjacent to a second biodegradable region. Further, the first biodegradable region includes a first biodegradable material, the first biodegradable material having a first rate of degradation. The second biodegradable region includes a second biodegradable material, the second biodegradable material having a second rate of degradation, wherein the first rate of degradation is different from the second rate of degradation.
