Catheters and uses of same are described. The catheter may be an aspiration or distal access catheter used to treat stroke or other neurovascular conditions and may include a proximal segment and a distal segment with fixed shapes and outer diameters, and a distensible segment that is located proximal to the distal segment and adjacent to the catheter distal end and that is configured to undergo a conformation change when the catheter open distal end is lodged against the wall of a human blood vessel and a surgeon is attempting to move the catheter distally through the human blood vessel. The catheter may include a wall that is comprised of an inner tube surrounding the catheter's hollow interior, a coil surrounding the inner tube, a braid surrounding the coil and/or an outer tube surrounding the braid. The pitch of the coil may be greater in the distensible segment as compared to the proximal segment and the outer tube may not be attached to the inner tube for at least a portion of the distensible segment, which features allow for the distensible segment to undergo the conformational change. The distal segment may include a metallic marker band, providing rigidity to the distal segment.

Embodiments herein describe tools and instruments for holding, transferring, delivering, deploying an implantable device and methods and means of aseptically storing and shipping the implantable device including but not limited to a device case for protecting, housing and filling the device, a surgical sizer for preparing the implantable site, a deployer for transferring the implantable device from the device case and delivering or deploying the implantable device at the prepared implantable site.

Tools and instruments for use with implantable encapsulation devices

Described herein are devices, methods, systems, and kits configured for use in the surgical treatment of cervical disc disease. Surgery for cervical disc disease may comprise vertebral fixation with screws and plates as well as insertion of one or more intervertebral implants. In some embodiments, a cervical implant may be connected as one single unit with a cervical plate. In some embodiments, a cervical implant and a cervical plate may be separate elements that are configured to be inserted independently into a subject during cervical spinal surgery. In some embodiments, a cervical implant and a cervical plate are designed to be coupled together.

Devices, methods, systems, and kits for the surgical treatment of cervical disc disease

Described herein are devices and methods for limiting the torque applied to surgical screw during a surgical procedure in which a surgical screw is passed into a vertebra, such as, for example, a spinal fusion procedure. A surgical screw driver is configured to prevent an excessive amount of torque from being delivered to the vertebrae through a surgical screw. When an excessive amount of torque is delivered to the handle of a surgical screw driver, it is prevented from being transmitted to the surgical screw and is thus not delivered to the vertebrae. Excessive force in the form of excessive torque transmitted to a vertebrae may cause a fracture along with possible mispositioning or displacement of a surgical screw.

Injection-molded devices and systems for graft or other tissue delivery, methods for their single-use in delivery of an implant, and kits for their sterile delivery to a practitioner are disclosed herein. Systems for implant delivery comprise an injection moldable implant body and an insertion device comprising: an inner and outer shaft that form a locking mechanism that secures an implant body in place and releases it upon placement within a patient. Systems are configured to be manufactured by injection molding, such that they can be cost-effectively manufactured and discarded after a single use to avoid costs and risks associated with re-sterilization and cleaning, but can in some cases optionally also be manufactured by machining to be re-sterilized and reused.

Lock and release implant delivery system

A bite block and methods of use thereof are disclosed. The bite block may be configured to encompass a tube such as an endotracheal tube, and to protect the mouth of an intubated patient from clenching damage.

Bite block

Disclosed is an apparatus and a method for surgical dilation and retraction of tissues during a medical procedure, for example a spinal surgery. The apparatus includes a dilator assembly that includes a plurality of slidingly engaging dilators, wherein at least one dilator includes an outer wall shape different from its inner wall shape. At least one of the dilators may include an eccentrically positioned circular channel, a generally oblong outer wall shape, and a longitudinal gap in a wall. The dilator system may be used in a method that provides off center differential dilation of tissues in one or more preferred directions. A retractor system that may be used with the dilator system is also disclosed.
