Abstract: This invention relates to a measuring device, which includes a body. A digital display is located in the body, the digital display being configured to show at least a linear measurement. The measuring device also includes a holding portion coupled to the body and configured to slidably engage an elongate member, such as a catheter or introducer sheath, in a space provided between the holding portion and the body. The measuring device also includes a sensor or transducer located in the body and configured to measure at least a linear distance traveled by the elongate member, such that the linear measurement is associated with the linear distance.

Abstract: A fluid infusion system includes a pump having a body that slidably interacts with a handle. The body includes a valve housing fluid coupled with an inlet passageway, an outlet passageway, and a dispensing barrel. A finger rest rigidly projects from the dispensing barrel. A loading chamber is recessed within the finger rest and is configured to receive a fluid supply syringe. A plunger, mounted to the handle, is slidably received within the dispensing barrel. As the plunger is advanced within the barrel, fluid is dispensed from the pump. As the plunge is retracted within the barrel, the barrel is automatically filed with a fluid. The nozzle of the pump is fluid coupled to a hemostasis valve which is in turn fluid coupled to an infusion catheter. The infusion catheter has a distal end with an enlarged tip opening and a plurality of small infusion holes extending through the side thereof. An annular sensing ridge radially inwardly projects from the interior of the catheter at the tip opening.

Abstract: An improved catheter includes a double spiral configuration of infusion holes around the circumference and along the length of the catheter which provides an improved lateral dispersion of a thrombolytic fluid to more completely and quickly lyse a clot through which the catheter is passing. The double spiral configuration consists of groups or sets of infusion holes, typically groups of four. The holes in each set are longitudinally spaced from each other at substantially regular intervals along the length of the catheter. Each successive hole in a given group is circumferentially spaced by an angular distance of about 90.degree. around the circumference of the catheter relative to the immediately preceding hole. Each group of holes is circumferentially spaced or offset by an angular distance of between 1.degree. and 89.degree. relative to the immediately preceding group of holes. Typically, the angular spacing between successive groups of holes is 18.degree..
