In various embodiments, a tissue thickness compensator can comprise one or more capsules and/or pockets comprising at least one medicament therein. In at least one embodiment, staples can be fired through the tissue thickness compensator to rupture the capsules. In certain embodiments, a firing member, or knife, can be advanced through the tissue thickness compensator to rupture the capsules.

An intraluminal device includes a radially expandable body and a control member operable to expand and contract the radially expandable body. The radially expandable body comprises plural sets of first filaments spiraling in a first direction from a proximal end portion to a distal end portion of the radially expandable body and plural sets of second filaments spiraling in a second direction from the proximal end portion to the distal end portion. The plural sets of first filaments intersect the plural sets of second filaments, forming plural cross sections of the radially expandable body. At least one of the plural sets of first filaments comprises a filament constructed of a radiopaque material.

A positioning system includes a group of positioning devices including a first device comprising a first positioning source associated with a first positioning modality, the first positioning source being configured to view a first field, a second device comprising a second positioning source associated with a second positioning modality that is of a different type than the first positioning modality, the second positioning source being configured to view a second field, a third device comprising one or more first markers detectable within the first field using the first positioning modality, and a fourth device comprising one or more second markers detectable within the second field using the second positioning modality. A linking structure physically links two of the group of positioning devices to one another in a fixed, rigid relative position and orientation.

Embodiments are directed to a medical robot system including a robot coupled to an end-effectuator element with the robot configured to control movement and positioning of the end-effectuator in relation to the patient. One embodiment is a method for removing bone with a robot system comprising: taking a two-dimensional slice through a computed tomography scan volume of target anatomy; placing a perimeter on a pathway to the target anatomy; and controlling a drill assembly with the robot system to remove bone along the pathway in the intersection of the perimeter and the two-dimensional slice.

Alignment precision technology, in which a system accesses image data of a bone to which a reference marker array is fixed. The system generates a three-dimensional representation of the bone and the reference markers, defines a coordinate system for the three-dimensional representation, and determines locations of the reference markers relative to the coordinate system. The system accesses intra-operative image data that includes the bone and a mobile marker array that is attached to an instrument used in a surgical procedure. The system co-registers the intra-operative image data with the three-dimensional representation by matching the reference markers included in the intra-operative image data to the locations of the reference markers. The system determines locations of the mobile markers in the co-registered image and determines a three-dimensional spatial position and orientation of the instrument relative to the bone.

A non-occlusive device is provided that includes a coilable section and a docking section. When deployed from a microcatheter within a wide-neck vascular aneurysm, the coilable section is configured to become coiled into a coil defining a sequence of concentric loops, and to bridge a neck of the aneurysm so as to at least partially cover an orifice of the aneurysm, when in use. The docking section is configured to be deployed from the microcatheter within the aneurysm. The docking section extends distally from an outermost one of the concentric loops of the coil, and is shaped so as to define one or more concentric loops having an outer diameter less than an outer diameter of the concentric loops of the coil. The docking section is configured to anchor, stabilize, and/or assist with positioning of the device within the aneurysm. Other embodiments are also described.

Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, a leaflet connector carried by a distal end of the catheter can be anchored to a superior surface of a mitral valve leaflet. A needle is axially advanceable through the leaflet connector and through the leaflet. A leaflet anchor having a leaflet suture can be advanced out of the needle to secure the mitral valve leaflet to the leaflet suture. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.

A method for localizing a nodule of a patient includes inserting a delivery tool into tissue of a patient, such as lung tissue, releasing the magnetic fiducial into or adjacent a nodule from the delivery tool, and locating the magnetic fiducial with a localization tool.

System for inserting a self-expandable occluder (12) into a patient and for releasing the occluder (12) in the left atrial appendage (10) of the patient, the system including an insertion unit (100) which has a drive unit (102) and an insertion catheter including an outer tube and an inner tube extending through the outer tube, wherein a proximal end region of the occluder is movement-coupled to the outer tube, and wherein a distal end region of the occluder, is movement-coupled to the inner tube, wherein, in order to release the occluder, the drive unit interacts with the inner tube and the outer tube such that, when actuated, the inner tube can be moved in a distal or proximal direction and the outer tube can be moved in the proximal direction or distal direction, so that the distal end and the proximal end of the occluder can be moved away from or toward one another.
