The present disclosure provides devices, kits and methods for preparing injections with cells and carrier components for delivery to a target area in the body. The disclosed devices, kits, and methods provide preparation and monitoring of injections.

Multi-component injection system and methods for tissue repair

A method of localizing a medical device inside a patient's body, the method comprising: transmitting ac magnetic signals between a plurality of points of known location outside of the patient's body and a plurality of points on the medical device inside the patient's body, the signals transmitted between at least some of the points comprising at least two different frequencies; and receiving the transmitted ac magnetic signals and processing the received signals to determine the position of the points on the medical device, and thus the location of the medical device, this processing including correcting for the affects of metal in the vicinity by using the transmitted and received signals at different frequencies. In an alternate embodiment, a reference device is provided inside the patients' body, and the medical device is localized relative to the reference catheter. The use of signals comprising at least two frequencies may or may not be used in this relative localization embodiment, but preferably is used at least to localize the reference catheter.

Method of localizing medical devices

Generally, the shielded x-ray source of the present invention has a cast shield of an iron based material substantially enclosing and closely conforming to the x-ray tube to shield the x-ray tube imaging beam from interference from magnetic fields. The method of the present invention includes providing a shield cast from an iron-based material in a shape having a cavity to receive and closely conform to the x-ray tube, and installing the cast shield around the x-ray tube. The magnetic surgical system comprising at least one magnetic for magnetically navigating a medical device in an operating region in a patient's body, and an imaging apparatus including at least one x-ray tube for imaging the operating region. A cast shield of an iron-based material substantially enclosing and closely conforming to the at least one x-ray tube.
