The present disclosure provides a cutting tool for surgical procedures. More specifically, the present cutting tool is suitable for bi-directional cutting and removal of soft and hard tissues for surgical procedures. The cutting tool includes a substantially rigid shaft having a shaped end portion. The shaped end portion includes a plurality of shaped talons; each talon including a body bent to retain tissue, and each talon including a cutter end. The cutter end includes both acute and obtuse cutting surface relief angles for diverse cutting action with respect to hard and soft tissues.

A surgical tool that has a pair of transmissions coupled to one another to effect driving of a cutting tool in both bidirectional intermittent rotational manners and in opposite directions of continuous rotation. The transmissions are driven by a motor coupled to one of the transmissions which is coupled to the second transmission.

The present disclosure relates to a tissue cutting system for cutting tissue of a heart, such as tissue of a septum of a heart, comprising: an outer tubular member having a proximal portion and a distal portion, said distal portion comprising a tissue resection window; a resection element axially slidably arranged inside the outer tubular member configured to resect tissue extending through the tissue resection window; at least one pressure sensor; wherein the outer tubular member and resection element are arranged to establish: a first fluid flow channel suitable for transporting resected tissue away from an area adjacent to the resection element; at least one second fluid flow channel configured to assist the first fluid flow channel in transporting resected tissue. The present disclosure further relates to a method for resecting tissue using the disclosed tissue cutting system.

Disclosed herein is a medical device. The medical device includes a blade tube section, a solenoid, and a mechanical arrangement. The blade tube section includes an outer blade tube, an inner blade tube, and a cutting window at a distal end of the blade tube section. The solenoid is offset from a central axis of the blade tube section. The mechanical arrangement is between the inner blade tube and the solenoid.

Discectomy instruments and methods thereof. The discectomy instrument may include a cutter tip configured to release disc material between adjacent vertebrae. The cutter tip may be pivotable such that the cutter tip is positionable off-axis from an access port. The discectomy instrument may be a powered instrument with a constant velocity joint that acts as a point of articulation as well as drive transfer.

A medical instrument for dislodging vertebral disc material from a vertebral disc in a vertebral disc space via a cannula has a pivoting scoop structure with a scoop that provides a 180° pivot sweep outside of the diameter of the cannula. The medical instrument has an elongate body defining a longitudinal axis with the pivoting scoop structure situated at a distal end of the elongate body. The elongate body has a first elongate shaft and a second elongate shaft situated on and configured for longitudinal axial translation relative to the first elongate shaft. Axial movement of the second elongate shaft controllably swivels the pivoting scoop structure from, through, and between 0° to 180° relative to the longitudinal axis of the elongate body. The scoop structure may also allow for collection and removal of dislodged vertebral disc material.

A lateral disc cutter for morcellating and decorticating tissue of an intervertebral disc from between adjacent vertebrae. The device can be arranged in a retracted configuration for insertion via an access tube, and in an extended configuration for cutting of tissue in the target region. The blades may be extended to contact the concave endplate in an orientation that is substantially parallel to a mid-plane of the intervertebral disc. Blades of the device may be configured with a convex profile that substantially conforms to the concave shape of the endplate for enhanced contact length between the blade and the endplate. In some embodiments, the blades are configured for removal and replacement without need for tools, with the blades selectively determining a maximum displacement width of the morecellator assembly.

A neuro stimulator adapter for a tissue removal device is disclosed. In certain arrangements, the adapter includes an engagement sleeve and a hub. The engagement sleeve is fixedly connected to a portion of the hub. In certain arrangements, the hub further has a contact assembly disposed therein, the contact assembly configured to be connected to an electrical source to deliver neurostimlation to the tissue removal device at a distal end thereof.

A spinal joint distraction system for treating a facet joint including articular surfaces having a contour is disclosed and may include a delivery device including a generally tubular structure adapted to engage a facet joint, an implant adapted to be delivered through the delivery device and into the facet joint, the implant comprising two members arranged in opposed position, and an implant distractor comprising a generally elongate member adapted to advance between the two members of the implant causing separation of the members and distraction of the facet joint, wherein the implant is adapted to conform to the shape of the implant distractor and/or the articular surfaces of the facet upon being delivered to the facet joint. Several embodiments of a system, several embodiments of an implant, and several methods are disclosed including a method for interbody fusion.

An interventional device for cutting tissue at a targeted cardiac valve, such as a mitral valve. The interventional device includes a catheter having a proximal end and a distal end. A cutting mechanism is positionable at the distal end, such as by routing the cutting mechanism through the catheter to position it at the distal end. The cutting mechanism includes one or more cutting elements configured for cutting valve tissue when engaged against the tissue. A handle is coupled to the proximal end of the catheter and includes one or more controls for actuating the cutting mechanism.
