A method for treating spinal nerve compression includes sequential dilation to position an instrument cannula along a patient's spine. Instruments can be delivered through the instrument cannula to remove targeted tissue for a decompression procedure. One of the instruments can be a reamer instrument configured to abrade, cut, or otherwise affect tissue along the patient's spine.

A medical apparatus according to one embodiment of the present invention can be used for dissociating adhesion to an epidural space and alleviating stenosis to a spinal canal; and comprises: an insertion part including a first end configured to be inserted into a human body and a second end opposite to the first end, and having a first through hole extended from the first end to the second end and formed inside the insertion part, an expansion part configured to be expandable and formed on an outer surface of the insertion part at a predetermined distance apart from the first end of the insertion part, a pair of wires extending in the insertion part and fixed to a region of the first end of the insertion part, a main body, a dial installed to the main body, and a rotation control part coupled to the dial.

A portable and passive safety intraosseous device to allow for direct introduction of medications, etc., within the intermedullary space of a subject patient's bone or, if needed, the removal of certain substances from such a subject patient's bone. Such a device permits direct drilling and placement of a cannula within the subject bone with access external to the subject patient's skin, permitting, as well, connection of a tube for such introduction/removal purposes. The ability to provide a passive safety unit allows for facilitated utilization in, for instance, emergency situations with the entire device provided for utilization thereof. The device includes a drilling component with a permanently attached stylet and a removable cannula, a power supply for a single drilling operation, a mechanism to draw the stylet back into the drill component after use and disengagement from the cannula, and an automatic closure that activates with the separation of the cannula.

A device is described for marking a path on a skin surface for inserting an epidural needle into an epidural space. The device includes a first arm having one or more holes spaced apart along the length of the first arm. A pin is attached at the proximal end of the first arm. A second arm has a proximal end attached to the pin allowing the first and second arms to rotate about the pin to adjust an angle separating the first and second arms. The second arm has one or more holes spaced apart along the length of the second arm. The holes on the first and second arms provide locations for marking the path on the skin surface to insert the epidural needle.

Within examples, a wire clamping device includes a base. The base includes an indentation, a first attachment component at a first end of the base, and a second attachment component at a second end of the base that is opposite the first end. The wire clamping device further includes an arm that includes a protrusion and a third attachment component that is attached to the first attachment component. The arm is configured to rotate with respect to the first attachment component to a position at which the arm is restrained by the second attachment component against the base and at least a portion of the protrusion is within the indentation or aligned with the indentation. Additional examples include a method for using the wire clamping device, a tool for opening the wire clamping device, and a method for using the tool to open the wire clamping device.

Provided is a guide device for puncturing with a puncture needle from a puncture point A provided at a vicinity of a first point B on a waist of a patient to a target point D inside a patient's body, the target point D corresponding to a second point C different from the first point B on the waist. The guide device includes a guide part for guiding the puncturing with the puncture needle, and a support base for supporting the guide part and abutting on the waist. A portion of the support base is configured to define a first angle with respect to a straight line connecting the puncture point A and the second point C, and the guide part is provided at a second angle with respect to a line perpendicular to the support base. The first angle is defined by the puncture point A, the second point C and the first point B, and the second angle is defined by the puncture point A, the target point D and the second point C. Accordingly, it is possible to provide a guide device capable of easily and accurately puncturing a target point with a puncture needle regardless of a patient or an operator.

An intrathecal needle closed system for spinal needle that reduces the incidence of Post Dural Puncture Headache (PDPH) and infection. The intrathecal needle closed system generally includes closed system with CSF indicator, CSF indicator port, introducer needle, standardized needle size, and re-insertable stylet in closed system.

A device includes a push rod that extends through a portion of a shaft, and an end of the push rod is translated by rotating a lever. The device further includes a needle assembly coupled to an end of the shaft, and the needle assembly includes a first needle arm and a second needle arm that are pivotable between a first open position and a second closed position. When the lever is rotated by a user, the end of the push rod is configured to contact a portion of the needle assembly to displace the needle assembly from a first open position into a second closed position.

An apparatus for loading an endovascular shunt into a delivery catheter includes a base, a boss rod connected to, and extending longitudinally across, the base, and a plurality of guide bosses slidably coupled to the boss rod. The guide bosses include a delivery catheter guide boss coupled to the delivery catheter, a malecot holding tube guide boss, wherein a malecot holding tube is connected to a first lateral side of the malecot guide boss extending towards the delivery catheter guide boss, a claw assembly guide boss, where a claw assembly is attached to a first lateral side of the claw guide boss extending towards the malecot holding tube guide boss, and a chase pin guide boss, wherein a chase pin is connected to a first lateral side of the chase pin guide boss extending towards the claw assembly guide boss.

A drug delivery system comprising: a plurality of needles; a needle guide for guiding and holding the plurality of needles during insertion into a patient's spine; a syringe containing a drug which is to be delivered into the patient's spine; a port multiplier comprising an inlet port connectable to the syringe and a plurality of outlet ports; and a plurality of tubes for providing fluid connections between the outlet ports of the port multiplier and the plurality of needles.
