Abstract: A support catheter may be used in combination with a guidewire or other medical device. The support catheter may be adapted to provide both high pushability and good torque response. The elongate shaft of the support catheter may include a polymeric inner layer, stainless steel braided layer disposed over the polymeric inner layer, and a polymeric blend layer that is extruded directly over the stainless-steel braided layer. The construction of the elongate shaft may provide the support catheter with a pushability value of at least 900 grams per centimeter and a torque response value of less than 300 degrees.

Abstract: Fingerprinting, including: receiving a plurality of master datasets, each master dataset divided into a plurality of input segments, wherein at least one master dataset of said plurality of master datasets is uniquely marked; selecting a corresponding input segment from one of said plurality of master datasets; storing a segment identifier indicating from which master dataset said selected corresponding input segment was selected; and sending said selected corresponding input segment to a client computer system over a computer network.

Abstract: A percutaneous nephrolithotomy (PCNL) needle may include a cannula including a shaft and a cannula hub coupled to a proximal end of the cannula shaft. A depth guide may be disposed on an outer surface of the cannula shaft.
