摘要:
An endoscope is communicatively coupled to electronics that receive images of tissue from the endoscope and determine a correlation between the received images and images of normal and abnormal tissues in a database. Based on the determined correlation, an operator of the endoscope is notified of the correlation and the electronics can cause the endoscope to act accordingly (e.g., biopsy abnormal tissue).

A disposable catheter and reusable stylet assembly is disclosed. The disposable catheter prevents infectious bodily fluids and tissues from making contact with the stylet. The catheter includes an implantable elongated tube connected to a stylet receiving body. The stylet includes a control handle that can be coupled or engaged to the receiving body. The stylet also includes a stylet member that can extend within the catheter tube. An image capturing component can be positioned at the distal end of the stylet member. A control mechanism can control the movement of the stylet member.

A catheter assembly is provided with a first visual device and a second visual device. The second visual device is movable with respect to the first visual device to provide image feedback of a lesion from a different prospective than the first visual device. The second visual device can be moved before, contemporaneously with, or subsequent to a diagnostic or therapeutic procedure. The second visual device can include an elongated tube that can be extended into or retracted out from an insertion tube of the catheter assembly.

An endoscope includes an imaging device, a first polarizing filter disposed in front of the imaging device, a light source, and a second polarizing filter disposed in front of the light source.
摘要:
An endoscope includes an imaging device, a first polarizing filter disposed in front of the imaging device, a light source, and a second polarizing filter disposed in front of the light source. The planes of polarization of the first and second polarizing filters are at a substantially 90° angle.

摘要:
A stone capture device comprises a shaft with a deployable sweeping structure at its distal end. The shaft is adapted to be removably placed over and connected to a conventional ureteroscope. The combination of the stone capture device and ureteroscope can be introduced into the urinary tract to capture, fragment, and remove stones from the bladder and kidney.
摘要:
A luminal occlusion device comprises a tension member, an elongate shaft, and a flat film having an axial receptacle which is received over a distal portion of the tension member. The flat film has proximal and distal ends which are attached to the distal ends of the tension member and the elongate shaft, respectively. Thus, distal advancement of the tension member relative to the shaft will cause the flat film to assume a low profile configuration, while proximal retraction of the tension member relative to the elongate shaft will cause the flat film to assume a foreshortened, compacted configuration. The film usually includes one or more radioopaque markers which help shape the compacted film.
