Abstract: A steerable device, such as a steerable catheter, may include a control handle and an insertion shaft extending outwardly therefrom. In use, the insertion shaft is navigated to an area of interest for examination and/or treatment thereof. The steerable device may include a steering system that controls the deflection angle of the distal end of the insertion shaft in two or more non-planar directions for navigating the insertion shaft to the area of interest. The steering system may also include a locking mechanism for arresting or partially arresting the movement of the distal end of the insertion shaft in a first direction independent of arresting or partially arresting the movement of the distal end in a second non-planar direction.

Abstract: In one aspect of the present disclosure, a device may include a shaft having a distal end, and a tip at the distal end of the shaft. The tip may include an opening defined by a surface of the tip. An instrument inserted through the shaft may extend distally out of the opening. The device also may include an elevator for engaging the instrument. The elevator may include a proximal end fixed relative to the surface of the tip, a proximal portion extending distally from the proximal end, and a distal portion extending distally from the proximal portion. A force exerted on the elevator bends the proximal portion to deflect the distal portion without bending of the distal portion.

Abstract: Medical systems and methods for making and using medical systems are disclosed. Example medical systems may include an atherectomy system configured to engage and remove plaque from walls in vessels of a vascular system. The atherectomy system may include a drive shaft, a rotational tip coupled to an end of the drive shaft, a motor coupled to the drive shaft to rotate the rotational tip, and a controller configured to control a motor state of the motor. The controller may adjust a range of possible load outputs from the motor and/or a maximum load output from the motor to account for external loads acting on the drive shaft and/or rotational tip rotated by the motor and facilitate passing an occlusion in a vasculature of a patient.

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: A medical system that includes a medical device having an imaging device configured to capture images of a target site. A location of the target site is determined based on the images. The medical device includes a light source configured to direct light onto the location of the target site, and a processor and non-transitory computer readable medium storing instructions that, when executed by the processor, causes the processor to move a sensor of a medical instrument toward the location of the target site based on the sensor detecting the light at the target site.

Abstract: The present disclosure provides apparatus and methods to both infer stent expansion (vessel expansion or compliance) and probability of procedural success (vessel patency) from pretreatment diagnostic imaging at the point-of-care and also train an inference model to generate such an inference, thus allowing a physician to choose with greater certainty an optimal treatment tool and treatment protocol for treating a vessel of a patient.

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 Gl 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 Gl area of the patient.
