摘要： A needle and catheter system, including components, is provided such that the position of an epidural needle may be identified after insertion into the body of a patient by electrically stimulating and thus locating a specific nerve. When a specific nerve is located, the catheter is inserted through the needle to a point slightly beyond the distal tip of the needle. The catheter tip may then be manipulated and the optimum position for the catheter tip determined by applying an electrical voltage through the helical wire to the proximal tip of the helical wire, this electrical stimulation being utilized in locating the specific location of the catheter tip within the nerve. Once optimum placement is achieved, the catheter is utilized for continuous administration of anaesthetic. A catheter adapter is utilized to allow easy access to the catheter and introduction of fluid into the nerve of the patient through the catheter tip. The catheter and catheter adapter are also provided with components so that the catheter adapter can be in place for during electrical stimulation of the target nerve.

摘要： A needle and catheter system, including components, is provided such that the position of an stimulating needle may be identified after insertion into the body of a patient by electrically stimulating and thus locating a specific nerve. Positioning of the stimulating needle while simultaneously controlling and monitoring the electrical impulses applied therethrough is made possible by a control device and monitor integral with the stimulating needle. When a specific nerve is located, the catheter is inserted through the needle to a point slightly beyond the distal tip of the needle. The catheter tip may then be manipulated and the optimum position for the catheter tip determined by applying an electrical impulse through the helical wire and/or the ribbon support wire to the proximal tip catheter, this electrical stimulation being utilized in determining the specific location of the catheter tip within the nerve. Once properly located, or at any time relative movement between the catheter and needle is not desirable, the catheter can be locked into position with a catheter lock which may be part of the stimulating needle hub. A catheter adapter is utilized to allow easy access to the catheter and introduction of fluid into the nerve of the patient through the catheter tip.

摘要： A stimulating needle and catheter system, including components, is provided such that the position of the stimulating needle or the stimulating catheter may be identified after insertion into the body of a patient by electrically stimulating and thus locating a specific nerve. Use of the needle and catheter system is eased by providing the system to the medical practitioner in a unitary structure. That is, the needle and catheter are connected by a catheter lock. The catheter lock is attached to the hub of the needle and can be actuated to either firmly grip the catheter or allow the catheter to move axially with respect to the lock and needle assembly. Thus, supplying the catheter to the practitioner already locked into the catheter lock allows the practitioner to insert the needle into the patient and, when ready, release the catheter for disposal through the needle into the patient. This and other disclosed features allow the medical practitioner to focus attention on the medical procedure.

摘要： A stimulating needle and catheter system is provided for delivery of an anaesthetic drug to a nerve having a fascia sheath. The position of the stimulating needle may be identified after insertion into the body of a patient by electrically stimulating and thus locating a specific nerve. When a specific nerve is located, the catheter is inserted through the needle such that the distal tip of the catheter is located at a point slightly beyond the distal tip of the needle. The distal tip of the catheter may then be manipulated and the optimum position within the nerve determined by applying an electrical impulse through a wire located within the catheter from the proximal end to the distal tip of the catheter. A tunneling device is inserted into the skin of the patient to form a subcutaneous tunnel through which the proximal end of the catheter is inserted.
