Abstract: Medical devices and methods for using medical devices are disclosed. An example medical device may include a tubular member having a lumen defined therein and a proximal end. A shaft may extend through the lumen. The shaft may have a distal end and a proximal end. An end effector may be attached to the distal end of the shaft. A handle may be coupled to the proximal end of the tubular member. The handle may include a base, a first hub member attached to the base, a second hub member coupled to the first hub member, and a cap attached to the second hub member.

Abstract: A medical device may include an end effector configured to perform a therapeutic procedure. The medical device may further include a guide having a modifiable shape. The guide may be adapted for insertion through a lumen of an access tube. Also, the end effector may be selectively attachable to the guide and configured to move along the guide.

Abstract: Medical devices are disclosed including polypectomy snare devices. An example polypectomy snare device may include an elongated sheath having a distal end. A hollow shaft may extend through and be movable relative to the sheath. A distal portion of the shaft may have a slit formed therein. The shaft may be shiftable between a first configuration wherein the distal portion is substantially straight and a second configuration wherein the distal portion includes a bend. A snare wire may be disposed within the shaft. A distal section of the snare wire may extend through the slit when the shaft is in the second configuration.

Abstract: A device in the form of a conversion adapter for reducing an internal lumen of a catheter so as to accommodate a guidewire having a diameter substantially smaller than the internal lumen of the catheter as well as a catheter system including such a conversion adapter is provided. The adapter is positionable within the internal lumen of the catheter. The adapter has an external diameter which is substantially equal to the internal lumen of the catheter and further includes a smaller internal lumen which is substantially equal in diameter to the guidewire and is therefore capable of accommodating the smaller diameter guidewire therethrough. Preferably, the adapter extends within the internal lumen of the catheter along the entire length thereof, and preferably extends beyond the length of the catheter, including a flexible tapered tip at the end portion.
