Estimating the term…
A connector for clamping lead bodies into connector bores in implantable medical devices has several alternative embodiments. In each there is a handle that has a fixed relationship with an axle member that connects through the connector block perpendicular to the long axes of the connector bores for the leads. A large, manually operable flag or handle member clicks into position to lock the lead in by positioning a saddle portion against the lead body in the bore. The handle may be split into legs or the axle may be split into legs and the space between the legs filled with medical adhesive if desired. Likewise a soft material elastomer may surround the saddle portion to prevent rough contact with the lead body.
A handle unit for use in an implantable medical device with a base for connecting said implantable medical device to a lead body end, said handle for use by direct manual operation to close off and open to lead access and engagement in said bore, said handle unit comprising;
A handle unit as set forth in claim one wherein said handle member has a top portion and two leg portions each of said leg portions connected to one of said longitudinal portions of said axle member substantial part.
A connector block for use by fixation to an implantable medical device such that an electrical connection between a circuit in an implantable medical device and electrode in a medical lead is establishable by insertion of said medical electrical lead into a lead bore in said connector block and wherein said lead bore has a long axis, said connector block comprising a hard plastic block with a sleeve like cavity formed therein, said sleeve like cavity adapted for and having inserted thereinto a handle actuated rotatable axle and having a through-axis substantially parallel to said inserted axle and substantially perpendicular to said lead bore long axis, and wherein said handle is sufficiently large for manual use and permanently affixed to said rotatable axle.
A connector block for use by fixation to an implantable medical device such that an electrical connection between a circuit in an implantable medical device and electrode in a medical lead is establishable by insertion of said medical electrical lead into a lead bore in said connector block and wherein said lead bore has a long axis, said connector block comprising a hard plastic block with a sleeve like cavity formed therein said sleeve like cavity adapted for insertion of a handle actuated rotatable axle thereinto and having a through-axis substantially perpendicular to said lead bore long axis wherein said sleeve like cavity has a substantially round passage therethrough but has four corner-like detents in a substantially square configuration arranged around said substantially round passage.
An implantable medical device having a connector block and handle mounted therein such that said handle imparts mechanical movement to an axle member fixed thereto, said axle member being mounted in said connector block perpendicularly across a lead bore formed in said connector block, and such that said handle in a position for providing locking connection between said medical device to medical electrical leads is locked by manual movement of a portion of the handle behind a detent formed in said connector block.
A method for operatively coupling a medical electrical lead to a connector block of an implantable medical device comprising;
