Ramped biopsy needle device

A biopsy needle system, comprising:

• a needle extending from a tissue piercing distal end to a proximal end, the needle defining a lumen extending from the distal end and configured to house a target tissue;
• an elongated member extending from a proximal end to a distal end, the elongated member defining a channel therethrough open at the proximal end, the channel sized and shaped to permit passage of the needle therethrough;
• and
• a rigid end cap coupled to the distal end of the elongate member, the end cap including an arced channel extending from the channel of the elongated member to a hole extending through a lateral wall of the end cap, the hole being sized and shaped to permit passage of the needle therethrough, a surface of the arced channel of the end cap comprising a ramp extending from the channel of the elongated member to the hole to guide the needle through the hole, the arced channel including three points of contact positioned along the arced channel, the three points of contact configured to contact the needle as the needle passes through the channel and to provide three force loads, as found in a three-point bend flexural system, to guide the needle through the hole without translating forces to the proximal end of the elongated member.
