Implantable adjuncts for use with a surgical instrument are disclosed. The implantable adjunct includes a first mesh positioned about a first side of the longitudinal knife slot and a second mesh positioned about a second side of the longitudinal knife slot such that the first and second meshes define a gap substantially aligned with the longitudinal knife slot of the staple cartridge body.

Visualization and ablation systems and catheters. The systems can capture a plurality of different 2D images of the patient's anatomy adjacent an expandable member, each of which visualizes at least one part of the patient that is in contact with the expandable membrane, tag each of the plurality of different 2D images with information indicative of the position and orientation of a locational element when each of the plurality of different 2D images was captured, create a patient map, wherein creating the patient map comprises placing each of the plurality of different 2D images at the corresponding tagged position and orientation into a 3D space, and display the patient map.

An end effector including an anvil and a staple cartridge assembly is disclosed. The staple cartridge assembly comprises a deck having steps defined thereon for compressing tissue positioned between the anvil and the staple cartridge assembly to different pressures. The staple cartridge assembly further comprises staples having different unformed heights removably stored therein. The staples are deformed against the anvil to different formed heights.

Methods are provided for extracting bone marrow cells from bone obtained from deceased donors, for preparing the bone marrow for cryopreservation and for obtaining desired cells from cryopreserved and fresh bone marrow.

A medical device configured to perform an endovascular therapy can include an elongate manipulation member and an intervention member. The elongate manipulation member can include a distal end portion. The intervention member can include a proximal end portion and a mesh. The proximal end portion can be coupled with the distal end portion of the elongate manipulation member. The mesh can have a plurality of cells in a tubular configuration and being compressible to a collapsed configuration for delivery to an endovascular treatment site through a catheter and being self-expandable from the collapsed configuration to an expanded configuration. The mesh can include an anodic metal and a cathodic metal. The anodic metal and the cathodic metal can each form a fraction of a total surface area of the mesh.

A flexible catheter with a drive shaft, and associated devices and systems. In some examples, the disclosure describes a flexible catheter with a drive shaft, with a sleeve surrounding the drive shaft and with a sheath surrounding the drive shaft and the sleeve, wherein the drive shaft, the sleeve and the sheath are pliable, wherein the drive shaft at a proximal end of the drive shaft comprises a coupling element for connecting the drive shaft to a drive motor, wherein the drive shaft at least regionally consist of a alloy which contains at least 10% by weight of chromium, nickel and cobalt in each case.

An end effector for use with a surgical instrument includes an anvil with at least one staple pocket that defines a longitudinal axis. The staple pocket comprises a first cup and a second cup. The end effector also includes a staple cartridge.

An accurate and precise surgical guide for dental procedures, especially a procedure involving a subject with few or no teeth as well as methods for making and use of such guides.
