Cap with integrated magnet and magnetic shield for tissue penetration devices

Abstract

A cap for a shaft of a magnetized tissue penetrating medical device is disclosed which includes a sleeve member having a hollow body to form a protective closure on the shaft of the tissue penetrating medical device. The proximal end of the hollow body provides a receiving space for receiving the shaft of the tissue penetrating medical device. One or more magnets are disposed on the sleeve member. The magnetic shield is composed of one or more shielding materials associated with the cover, which minimizes any influence of the magnetic field generated within the cover on the clinical environment. A medical device and method of magnetizing a shaft of a tissue penetrating medical device using the cover is also disclosed.

Description

technical field [0001] Aspects of the present disclosure relate to a cover for passively magnetized tissue penetrating medical devices for procedure guidance utilizing magnetic sensors to locate and project the position of features on the tissue penetrating medical device relative to target anatomy When used together, the system enhances visualization during invasive procedures while shielding the clinical environment and equipment from exposure to magnetic fields generated within the cover. Background technique [0002] Traditionally, during catheterization, invasive medical devices such as needles and catheter tubing pass through skin tissue to reach veins invisible to clinicians. For this reason, clinicians must rely on their first-hand needle insertion experience, combined with tactile sense, to successfully identify the location of the vein. This can be a difficult task when attempting to access small veins deep under the skin, increasing the patient's risk of excessiv...

Problems solved by technology

[0005] In systems of the type shown in Figure 1, needle damage that is not obvious to the user may occur, which can negatively affect the insertion process

Furthermore, the step of user actively magnetizing the metal cannula has some limitations and inherent risks, as this method cannot guarantee consistent magnetization due to variability in clinician procedures such as insertion depth, processing speed, and alignment of the needle in the magnetizer. will result in varying degrees of magnetization in the
