A bone fastener comprises a first member defining a plurality of grooves. A coupling member is disposed with the first member. A first band and a second band are disposable within the grooves. A second member is configured to penetrate tissue and includes a head engageable with the first band to provisionally connect the first member to the second member. The coupling member is engageable with a part to move the part relative to the first member into engagement with the second band to dispose the second band adjacent the first band to connect the first member to the second member. Systems, surgical instruments, implants and methods are disclosed.

A surgical retractor for positioning within an incision within a body of a patient is described. The surgical retractor comprises a flexible air-impermeable bag surrounding an interior region and extending from a first end through a central region to a second end. The surgical retractor includes a first port in the central region, the flexible air-impermeable bag surrounding a first channel that extends from the first port towards the first end, a second port in the central region, the flexible air-impermeable bag surrounding a second channel that extends from the second port toward the second end, and a plurality of beads substantially filling the interior region of the flexible air-impermeable bag. The flexible air-impermeable bag is configured to rigidify in response to air being evacuated from the interior region to position and hold intra-incision contents within a surgical working space in a patient.

A blade for a cutting instrument, in particular for medical use, includes a first ceramic layer, a second ceramic layer, and a heating device arranged between the first ceramic layer and the second ceramic layer.

A bone fastener comprises a first member comprising a first surface defining an implant cavity. The first member includes a first part being non-rotatable relative to the first surface and a second part including a second surface defining a portion of the implant cavity and a slot. A second member is configured to penetrate tissue and is connectable with the first member. The first member is rotatable relative to the second member in a first plane of a body and the second part is movable relative to the first part in a second plane of the body such that the first part is relatively translatable in the slot. Implants, systems, instruments and methods are disclosed.

A tissue-removing catheter for removing tissue in a body lumen includes an elongate body and a tissue-removing element mounted on a distal end portion of the elongate body. The tissue-removing element is configured to remove the tissue as the tissue-removing element is rotated by the elongate body within the body lumen. An inner liner is received within the elongate body. The inner liner defines a guidewire lumen. The inner liner isolates an interior of the guidewire lumen from the elongate body and tissue-removing element such that rotational forces are not transferred from the elongate body and tissue-removing element to the interior of the guidewire lumen when the elongate body and tissue-removing element are rotated during removal of tissue from the body lumen.

An electrode assembly for an electrosurgical pencil includes an insulative core configured to support an active wire around a peripheral surface thereof and a ground electrode coupled about the insulative core and adapted for insertion within an electrosurgical pencil. A hypotube is disposed between the ground electrode and the active pin and encapsulates the active pin to insulate the active pin from the ground electrode. An active pin is included that is adapted for insertion within the pencil and has a tensioning assembly including: a set screw with threads that engage grooves of the active pin such that, upon rotation, the set screw advances to secure the active wire within the active pin; and a nut is fixed within the hypotube that includes grooves that engage threads of the active pin such that, upon rotation, the active pin translates proximally to tension the active wire about the insulative core.

A delivery system for delivering an implantable heart valve includes an outer shaft and an inner shaft that is slidingly disposable within an outer shaft lumen, the inner shaft including a distal end region. A plurality of fingers extend distally relative to the distal end region of the inner shaft and are adapted to releasably engage an implantable heart valve. A plurality of looped sheathing aids extend distally from the distal region of an inner shaft lumen and are adapted to guide the implantable heart valve back into the outer shaft lumen when the implantable heart valve is pulled back into the outer shaft lumen. Each of the plurality of looped sheathing aids include a distal petal adapted to engage tissue adjacent a native valve annulus in order to limit distal advancement of the implantable heart valve during deployment of the implantable heart valve.

A cannula for transferring a substance to and/or from a patient includes a rigid, tubular support sleeve, an inner sleeve, a transfer tube, and a conformal polymeric sleeve. The support sleeve defines a support sleeve lumen extending from a first opening at a proximal end of the support sleeve to a second opening at a distal end of the support sleeve. The support sleeve includes a rigid, MRI-compatible material. The inner sleeve is disposed in the support sleeve lumen and extends beyond the distal end of the support sleeve to a distal end of the inner sleeve. The inner sleeve defines an inner sleeve lumen. The transfer tube is disposed in the inner sleeve lumen and extends to or beyond the distal end of the inner sleeve to a distal end of the transfer tube. The transfer tube defines a transfer tube lumen terminating at an opening at the distal end of the transfer tube. The conformal polymeric sleeve surrounds at least a portion of the support sleeve and at least a portion of the inner sleeve. The conformal polymeric sleeve includes a transitional section extending from the distal end of the support sleeve and over the inner sleeve in a direction toward the distal end of the inner sleeve. The transitional section tapers inwardly in the direction toward the distal end of the inner sleeve.
