Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes inserting an intramural crossing device into the vascular lumen, positioning at least the distal tip of the crossing device in the vascular wall, advancing an orienting device over the crossing device such that an orienting element of the orienting device resides in the vascular wall, inserting a reentry device, and re-entering the true vascular lumen.

A surgical device includes an outer member, an inner member, and at least one locking element. The inner member is at least partially supported within the outer member. The at least one locking element is configured in a first arrangement of the surgical device to lock the inner member in a first position and configured in a second arrangement of the surgical device to unlock the inner member from the first position. The at least one locking element is configured to change from the first arrangement to the second arrangement upon coupling the inner member in an operational arrangement to a hand piece.

The present invention relates to a guiding needle for a suction tube, which is for increasing accuracy and preventing medical accidents by enabling an operator to accurately recognize the bent direction of the needle and to stably hold the needle by means of a handle portion formed inside the rear end of the needle connected to a tube or by means of a separate fixing handle coupled to the inside of the rear end of the needle. In other words, the present invention relates to a needle having the rear end thereof coupled to one end of a tube connected to a drainage container for discharging body blood of a patient, wherein the needle has a coupling part formed inside the rear end thereof and comprises a fixing handle detachably coupled to the coupling part.

Embodiments systems and methods for a platform that is configured to hold a medical device. In embodiments, a physician, nurse, medical practitioner, etc. may perform actions to change the positioning and orientation of the medical device while the medical device is secured to the platform. In further embodiments, the platform may include robotic components configured to change the positioning and orientation of the medical device.

Devices, systems, and computer-implemented and surgical methods for providing and/or using optical, visual, and/or audio feedback when using a surgical instrument, such as to position and orient an implant are disclosed. A device includes a frame and a C-ring. The frame includes a fixation component optionally located at a first end and a tracking array optionally located at an opposing second end. The fixation component can be positioned at or near a center axis of the C-ring and is configured to releasably engage a surgical instrument. The tracking array may include tracking elements, such as reflective surfaces. The C-ring may include a plurality of light sources optionally arranged in a radial pattern. The light sources may be selectively illuminated based on a determined realignment to provide optical feedback with respect to at least a direction in which the surgical instrument should be moved to achieve a planned alignment.

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 include an electronic emitter comprising 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 cannula device for removing, including by aspirating, bodily material is disclosed. The device may include a cannula and a hub. The cannula includes an open proximal end and a deflectable distal segment, and one or a plurality of distal orifices fluidly connected to the lumen. When distally extended from an outer guide cannula, the deflectable segment assumes a curved shape, which includes temperature-dependent curvature subject to elevated temperature along a memory metal length of the cannula.

Methods and surgical tools for treating back pain use a spinal facet debridement tool with cautery and denuding action and minimally invasive protocol that can denude and cauterize soft tissue associated with a synovial capsule of the spinal facet joint.

A sternal elevator apparatus is disclosed. The sternal elevator may include a panel, a support beam traversing the panel, and a post coupled to a proximal end of the panel. The apparatus may also include an indicator handle coupled to the sternal elevator, an actuator drive pivotably coupled to the indicator handle, and a housing movably coupled to the actuator drive. The sternal elevator apparatus may have an actuator drive incorporating a linear rack. The housing further may include a cylindrical gear where the cylindrical gear is engaged with the linear rack.
