An apparatus for sampling tissue includes a tissue engaging member for engaging and retaining a sample of a tissue structure, and a cutter surrounding the tissue engaging member. The tissue engaging member and cutter are both operative to translate longitudinally with respect to one another, and a mechanism prevents the cutter from moving distally, the mechanism being released and the cutter freed to move distally when the tissue engaging member is in a predetermined position, preferably distal of the cutter. Thereby, out of sequence operation, e.g., premature cutting of the tissue before the tissue engaging member is in position, is prevented.

An implantable connector electrically connects multi-conductor leads to an implantable medical device such as a neurostimulator. The connector is assembled directly into a hermetic feedthrough of the implantable device and utilizes the feedthrough housing as a sustaining structure for connector clamping. The receptacle contacts detachably connect proximal lead contacts to corresponding feedthrough pins, which provide pass-through connections to electronic circuitry contained in a hermetically sealed case. The receptacle contact has resilient contact tines designed to engage a corresponding lead contact in a sliding manner. The receptacle contact is integrated with a contact guard which protects the receptacle contact from inadvertent handling damage. The contact guard is substantially more rigid than the resilient contact to resist deformation. The contact guard protectively shields the receptacle contact tines and prevents unintended contact tine excursion. In one embodiment, the contact guard is pre-attached to the receptacle contact prior to joining to the feedthrough pin. In another embodiment, the contact guard is an integral part of the feedthrough pin. Numerous embodiments with contact preload are provided.
