Abstract
Safety adaptors for connecting external medical devices to lead connector elements of temporary medical leads extending percutaneously into a patient's body are disclosed. The safety adaptors comprise a first member attached to but movable in respect of a second member. An elongated bore receives a lead proximal end segment and includes the lead connector elements.
Claims50
A safety adaptor for connecting an external medical device to at least one lead connector element of a medical lead extending percutaneously into a patient's body, comprising:
- an elongated first member having an elongated bore extending between a first member first end and a first member second end for receiving a lead proximal end segment including the lead connector element upon insertion of the lead proximal end segment therein through the first member first end;
- a second member having a breech for receiving the first member and the proximal end segment, the second member having at least one breech connector terminal located in the breech for making electrical contact with the at least one lead connector element within the elongated bore upon moving the first member into the breech;
- and
- a hinge coupled between the first member and the second member to enable movement of the first member with respect to the second member between an open position wherein the lead proximal end is insertable into the elongated bore of the first member and a closed position wherein the at least one connector element is brought into contact with the at least one breech connector terminal such that the at least one connector element is electrically isolated within the safety adaptor.
A method of using a safety adaptor having a first member and a second member for connecting an external medical device to at least one lead connector element of a medical lead extending percutaneously into a patient's body wherein a hinge between the first member and the second member enables movement of the first member with respect to the second member between an open position enabling the insertion of the lead proximal end into an elongated bore of the first member and a closed position enabling contact between the at least one connector element and at least one breech connector terminal, comprising:
- inserting a lead proximal end segment including the lead connector element into the elongated bore of the first member, the elongated bore extending between a first member first end and a first member second end;
- moving the first member into a breech of the second member that receives the first member and the proximal end segment;
- making electrical contact between the at least one lead connector element within the elongated bore and the at least one breech connector terminal located in the breech upon moving the first member into the breach of the second member, such that the at least one connector element is electrically isolated within the safety adaptor;
- and
- electrically coupling the safety adaptor to the external medical device.
