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 guiding apparatus, system, method, and forceps device for facilitating placement of sutures in a surgical procedure. The apparatus including a shaft portion having a non-circular aperture extending laterally therethrough and a blade portion having a shank extending at an angle from the shaft portion and a blade having a blade aperture extending from the shank. The system includes a plurality of the apparatuses held substantially parallel by an elongated rod through the apertures of the shafts. The blade apertures guide the at least one suture to a desired location to pierce through a target body tissue.

According to some embodiments, systems and methods are provided for non-invasively detecting the force generated by a non-invasively adjustable implantable medical device and/or a change in dimension of a non-invasively adjustable implantable medical device. Some of the systems include a non-invasively adjustable implant, which includes a driven magnet, and an external adjustment device, which includes one or more driving magnets and one or more Hall effect sensors. The Hall effect sensors of the external adjustment device are configured to detect changes in the magnetic field between the driven magnet of the non-invasively adjustable implant and the driving magnet(s) of the external adjustment device. Changes in the magnetic fields may be used to calculate the force generated by and/or a change in dimension of the non-invasively adjustable implantable medical device.

Disclosed are methods and devices for bidirectional crossing of a vascular obstruction in a patient. The method includes the steps of advancing a first catheter transvascularly in a first (e.g., retrograde) direction towards a vascular obstruction, the first catheter having a first central lumen in communication with a first side port. A second catheter is advanced transvascularly in a second, opposite (e.g., antegrade) direction towards the obstruction, the second catheter having a second central lumen in communication with a second side port. The first and second side ports are aligned to place the first central lumen in communication with the second central lumen; and a wire is advanced through the first and second side ports such that a first end of the wire is on a first side of the obstruction and a second end of the wire is on a second side of the obstruction.

A medical device may include an elongated body, a balloon positioned at a distal portion of the elongated body, and one or more pressure-wave emitters positioned along a central longitudinal axis of the elongated body within the balloon. The one or more pressure-wave emitters may be configured to propagate pressure waves radially outward through the fluid to fragment a calcified lesion at the target treatment site. The at least one of the one or more pressure-wave emitters may comprise an electronic emitter including a first electrode and a second electrode. The first electrode and the second electrode may be arranged to define a spark gap between the first electrode and the second electrode, and the second electrode may comprise a portion of a hypotube.

A surgical cutting instrument including a first tubular member, a second tubular member, a sleeve member, a third tubular member, and an orientation member. The first tubular member includes a cutting tip. The second tubular member has a distal region forming a cutting window. The first tubular member is co-axially disposed within the second tubular member such that the cutting tip is selectively exposed at the cutting window. The first and second tubular members are co-axially disposed within the sleeve member. The third tubular member is co-axially disposed around an intermediate section of the first tubular member, an intermediate region of the second tubular member and the sleeve member. The orientation member is rotatable to transmit a rotational force applied to the orientation member to selectively rotate the second and third tubular members relative to the sleeve member to effectuate spatial rotation of the cutting window.

A surgical device includes a cartridge alignment mechanism that loads a cartridge onto an engagement portion without having to place the cartridge in proper orientation with the engagement portion.

A hemostatic device is disclosed, which capable of favorably keeping strength of an inflatable portion and easily adjusting a discharge speed of gas. The hemostatic device includes a band for wrapping around a wrist, a fastener or means for securing that secures the band to the wrist in a wrapped state, an inflatable portion connected to the band and inflated by being injected with gas, and a filter member that controls discharge of gas injected into the inflatable portion, in which the band has one or more hole portions penetrating between an inner surface and an outer surface of the band, the inflatable portion is disposed to cover the hole portions on the inner surface of the band, and the filter member is disposed on the band to block the hole portions and controls discharge of gas from the hole portions.

A positioning and retrieval device manipulated by carrying element coupled to a handle and driven by an actuator that allows for axial movement and rotational movement of a capturing portion on the carrying element.

A cannula system and method for accessing a blood mass in the brain. The system comprises a cannula with a camera mounted on the proximal end of the cannula with a view into the cannula lumen and the surgical field below the lumen. A prism, reflector or other suitable optical element is oriented between the camera and the lumen of the cannula to afford the camera a view into the cannula while minimizing obstruction of the lumen. The system may also include an obturator with a small diameter shaft and a large diameter tip which is optically transmissive, so that a surgeon inserting or manipulating the assembly can easily see that the obturator tip is near brain tissue (which is white) or blood (which is red).
