A cranial implant may include an interior guide portion, an exterior guide portion, and one or more flanges. In one example, the interior guide portion may be disposed in a burr hole of a cranium and include a distal end, a proximal end, an inner surface, and an outer surface. The distal end may be inserted further into the burr hole than the proximal end. The inner surface may at least partially define a channel that accepts an elongated member, and the outer surface may extend around the full circumference of the burr hole. The exterior guide portion may be coupled to the interior guide portion and may contact an external surface of the cranium. The interior guide portion may define one or more surface features configured to secure the interior guide portion to the burr hole or secure an elongated member within the channel of the cranial implant.

Cranial implant for device fixation in burr holes

A delivery system for percutaneously deploying a valve prosthesis. The system includes a catheter assembly including a delivery sheath capsule and a handle having an oscillating device. The capsule is configured to compressively retain the valve prosthesis during implantation. After the valve prosthesis is partially exposed during implantation, the oscillating device can create a vibratory motion to reduce the friction between the valve prosthesis and the delivery sheath capsule in order to recapture the valve prosthesis.

Transcatheter valve prosthesis delivery system with recapturing feature and method

A burr cap assembly is at least partially inserted into a burr hole within the cranium of a patient. The burr cap assembly enables a elongate member to be inserted through the burr cap assembly to access a brain of the patient. A shifting member of the burr cap assembly may be configured to enable the elongate member to move with shifting fluid and matter of the brain. The shifting member of the burr cap assembly may be configured to move within a cavity defined by the burr cap assembly. The shifting member may be configured to move in a direction that is substantially perpendicular to a longitudinal axis of the distal portion of the elongate member. The shifting member may at least partially retain the elongate member, so as the shifting brain applies forces upon the elongate member, the elongate member and the shifting member may move within the cavity.
