Cothren C.C. and Moore, E. A., "Emergency department thoracotomy for the critically injured patient: Objectives, indications, and outcomes," World J Emerg Surg., 2006; 1 :4. This may be partly due to the fact that emergency department thoracotomy is An aggressive operation, and its aggressive properties and associated imperfections limit its therapeutic possibilities

[0376] Example 1: Measurement of Response Time of Vascular Cannulation Device

[0377] Vascular cannulation device response time measurements were tested by puncturing a pressurized elastic tubing system filled with electrolyte solution using Device Example 269 (in Figure 41 shown in). The device is connected to a laptop computer through a data acquisition card, the sample input voltage of the device is at a frequency of 500Hz and wired as follows:

[0378] 1. Wiring is used to identify catheter piercing time: one wire, connected to needle 11, the other wires are connected to metal catheter connectors, which are in fluid communication with the rest of the elastic catheter system. Thus, the piercing of the elastic conduit through the needle 11 closes the circuit with the electrolyte solution, thereby indicating the piercing time.

[0379] 2. Wiring is used to identify lever movement time: Wires are connected to shafts 216 and 218 of lever 214 and lever 220, both of which are...

Abstract

The present invention provides for devices and methods for providing endovascular therapy, including facilitating establishment of vascular access, placement of endovascular sheaths, catheter tip localization, and administration of vascular occlusion. The invention includes a vessel cannulation device, an expandable sheath, an occlusion catheter, and a localizer each of which may be provided separately or used as part of a system. One embodiment of the invention is a vessel cannulation device including: a housing having a distal end with a distal tip and a proximal end; a guidewire lumen passing through the housing and at least the distal tip; a sensor coupled to the guidewire lumen; and an advancing member, which is configured for advancing at least one of a guidewire or a sheath and which is operably coupled to the sensor.
