The present invention relates to methods and devices for performing endoscopic cannulation, papillotomy and sphincterotomy and similar procedures. According to the present state of the art, endoscopic cannulation of the common bile duct and papillotomy and similar procedures are accomplished by advancing the device into an endoscope / duodenoscope so that the distal tip of the device exits the endoscope adjacent the sphincter muscles at the Papilla of Vater. The endoscope mechanisms are then manipulated to orient the distal tip of the device to the desired position for proper cannulation of the duct. Due to inconsistencies in, for example, the sphincterotome, anatomy, and endoscope manipulation, it is difficult to accurately and consistently position the sphincterotome for proper cannulation. The steerable sphincterotome of the present invention allows the physician to control the position of the distal tip of the device independently of the endoscope and adjust for inconsistencies in the device and the anatomy. According to the present invention, the handle to which the cutting wire is attached is freely rotatable relative to the catheter. The handle, secured to the cutting wire but rotatable relative to the shaft of the catheter, provides a mechanism to rotate the wire, transmitting the force to rotate the device tip. With the handle rotating independently of the shaft at the proximal end, the force can be applied directly to the distal tip without twisting the entire shaft. Also a rotation lock to maintain the orientation of the tip and / or a rotation marking, to indicate the amount of rotation may be included.

This invention presents a basketball training device which resembles a mannequin that defends against basketball players with a series of blocking motions. When a proximity sensor detects an approaching player, a control unit initiates waving of forearms, raising / lowering of upper arms, chopping motion of arms and torso raising and lowering. An audio circuit plays music or realistic background noises. When convex bottom of primary base is placed on a floor, weight of ballast and rechargeable batteries allows the device to return to an upright position when tipped. A gyroscopic unit within a control unit can activate when the device tips to ensure return of the device to an upright position. Alternatively, the unit can be placed with the secondary base, which features castors that allow the unit to roll when stuck and facilitates placement on a basketball court.

Provided is an anti-slip crutch tip apparatus that includes at least one vent opening, located on the side wall of a generally cylindrical section of a crutch tip body and extending into the tip body, so that the vent opening is surrounded by structure forming a portion of the generally cylindrical section of the tip body The at least one vent opening is in physical communication with a portion of at least one channel formed into a surface contact portion of the tip body, so that an unbroken fissure in the tip body resides as a structural breach extending between the side-wall entrance of the at least one opening and the physically communicative association of the at least one vent opening with the portion of the at least one channel. A corresponding method of preventing slipping of a support device tip is also provided.

The present invention relates to a microsurgical device and methods of its use for treatment of various conditions including eye diseases, such as glaucoma, using minimally invasive surgical techniques. The invention relates to a dual-blade device for cutting the trabecular meshwork (TM) in the eye. The device tip provides entry into the Schlemm's canal via its size (i.e., for example, 0.3-0.2 mm width) and configuration where the blade tip curves up providing a ramp-like action for cutting the TM. The dimensions and configuration of the blade is such that an entire strip of TM is removed without leaving TM leaflets behind and without causing collateral damage to adjacent tissues.
