Abstract: A tissue resecting instrument includes an end effector assembly having a proximal hub housing, a retainer cap extending proximally therefrom, an elongated outer shaft extending distally from the proximal hub housing, an inner cutting shaft rotatably disposed within the elongated outer shaft, and an inner core drive assembly that includes a proximal driver and a distal driver. The distal driver is coupled to the inner cutting shaft such that rotation of the distal driver rotates the inner cutting shaft relative to the elongated outer shaft. The proximal driver is slidable relative to the distal drive between a more-proximal position wherein the proximal driver is engaged with the retainer cap to rotationally fix the proximal driver, thereby rotationally locking the inner cutting shaft, and a more-distal position wherein the proximal driver is disengaged from the retainer cap permitting rotation thereof thereby permitting rotation of the inner cutting shaft.

Abstract: An end effector assembly of a tissue-resecting device includes an outer shaft defining a window, a drive wire extending through the outer shaft, and a distal cutting tip disposed within the outer shaft. The drive wire includes a cylindrical body and a distal end portion defining a semi-cylindrical configuration including a semi-cylindrical bottom surface and a planar top surface having a semi-cylindrical cut-out defined therein. The distal cutting tip at least partially overlaps the window and has a semi-cylindrical lumen defined by a semi-cylindrical bottom surface and an open top. The distal end portion of the drive wire is at least partially received and within the semi-cylindrical lumen with the semi-cylindrical surfaces substantially mating. The drive wire is configured to drive rotation or oscillation of the distal cutting tip relative to the outer shaft.

Abstract: Embodiments of this invention relate to a fluid delivery device. The fluid delivery device comprises a fluid reservoir for containing a fluid, a first drive mechanism configured to remove a predetermined amount of the fluid from the fluid reservoir when the first drive mechanism is actuated, a needle, a septum and a housing having an orifice. Also disclosed is a method for dispensing a fluid from a fluid delivery device into a patient.

Abstract: An end effector assembly of a tissue resecting device and a tissue resecting device including the end effector assembly and a handpiece assembly. The end effector assembly including a proximal hub housing, an inner drive core at least partially disposed within the proximal hub housing, a cutting member extending distally from the proximal hub housing and engaged with the inner drive core such that rotation of the inner drive core rotates the cutting member, and a lock and release mechanism operably coupled between the inner drive core and the proximal hub housing. The lock and release mechanism is transitionable between a locked condition rotationally fixing the inner drive core and the proximal hub housing relative to one another thereby rotationally locking the cutting member, and a release condition enabling relative rotation between the inner drive core and the proximal hub housing thereby enabling rotation of the cutting member.

Abstract: A method of revising a graft in a bone tunnel including unpinning a graft ligament support block from within a bone tunnel in a host bone, withdrawing the graft ligament support block from the bone tunnel to create a vacated bone tunnel, advancing a graft ligament support block into the vacated bone tunnel, and pinning the graft ligament support block within the bone tunnel. In one embodiment, the graft ligament support block includes a body having a graft hole and a transverse fixation pin hole extending through the body. The graft hole and the transverse fixation pin hole extend substantially perpendicular to the longitudinal axis of the body. An installation tool can be provided for inserting the graft ligament support block into the bone tunnel.
