International Classification:

A61B 5/0408

US Classification:

600374, 600509

Abstract:

An integrated catheter placement system for accurately placing a catheter within a patient's vasculature is disclosed. In one embodiment, the integrated system comprises a system console, a tip location sensor for temporary placement on the patient's chest, and an ultrasound probe. The tip location sensor senses a magnetic field of a stylet disposed in a lumen of the catheter when the catheter is disposed in the vasculature. The ultrasound probe ultrasonically images a portion of the vasculature prior to introduction of the catheter. ECG signal-based catheter tip guidance is included in the integrated system to enable guidance of the catheter tip to a desired position with respect to a node of the patient's heart. Various aspects for visualizing and manipulating display of the ECG signal data acquired via the present system, together with aspects of various ECG sensor configurations, are also disclosed.

International Classification:

A61B 8/13

US Classification:

600424

Abstract:

Systems and methods for assisting the placement of a catheter within the body of a patient through the use of an ultrasound imaging system are disclosed. In particular, the systems and methods described herein enable a clinician to determine, prior to insertion of the medical device, how much of the device will be disposed within the vessel, thus enabling the clinician to choose a catheter with suitable length. In one embodiment, an ultrasound imaging system for assisting with placement of the medical device comprises a console, a probe for producing an image of a target location, and a processor. The processor provides to a user proximity information relating to the anticipated proximity of the medical device to the target location prior to insertion of the medical device. A display is included for depicting the image, target location depth, and the proximity information of the medical device to the target location.

Abstract:

Systems and methods for navigation and positioning a central venous catheter within a patient. The system may include a first pole and a second pole designed to generate an electric field sufficient to obtain a plurality of field measurements. The system may include a stylet inserted into a medical device. The stylet may include a magnetic assembly configured to produce a magnetic field positioned along a distal portion of the stylet, and a stylet electrode positioned distal of the magnetic assembly. The stylet electrode may be designed to function as both an interior excitation electrode and an interior detection electrode. Advancement of the medical device in the patient may include using a conductance curve generated from the plurality of field measurements to identify an obstruction or malposition in the patient.

Abstract:

Needle guide systems for a sonography device are disclosed. The needle guide systems include both fixed and adjustable needle guides. In one embodiment, the needle guide includes a needle guide body that is rotatably mounted to a probe of a sonography device. A plurality of needle channels is disposed on a surface of the needle guide body. Each needle channel can be selectively rotated into position to guide a needle into a body of a patient at a predetermined needle insertion angle. If another needle insertion angle is desired, the needle guide is rotated to place a new needle channel defining the desired needle insertion angle into position. In another embodiment, a needle guide is disclosed and includes an extended guide feature, such as a guide cone, to assist in inserting a needle into the needle channel.
