Abstract
An engagement system for a surgical sensor assembly, formed of a sensing component in a fixed position and a lead wire in an electrical communication therewith. The engagement system employs a jacket of heat shrink polymeric material to hold the sensing component to the lead wire and eliminates the employment of soldering and welding and crimping which can damage such sensing components. The system is employed in combination with catheters having a lumen for control wires for surgical instruments.
Claims19
An engagement system of a surgical sensor assembly, formed of a sensing component in a fixed position upon, and communicating with, a lead wire, said engagement system comprising:
- a jacket of polymeric material;
- said jacket being formed by a first lumen of a multi-lumen catheter;
- said first lumen having a first seal at a distal end and a second seal at a proximal end of said catheter;
- a distance between said first seal and said second seal thereby defining a distance of said first lumen;
- said distance being equal to or slightly less than an aggregate length of said surgical sensor assembly formed by an said sensing component in operative electrical engagement to said lead wire;
- contact of said sensing component and said lead wire with said first and said second seals, providing a biasing force upon said sensing component, said biasing holding said sensing component in said operative electrical engagement to said lead wire;
- and
- said jacket positioned to surround both said lead wire and said sensing component for an aggregate length of said assembly formed of said sensing component operatively engaged to said lead wire, whereby said sensing component is held in operative electrical engagement to said lead wire by a contact between said jacket and respective exterior surfaces of said sensing component and said lead wire.
An engagement system of a surgical sensor assembly, formed of a sensing component in a fixed position upon, and communicating with, a lead wire, said engagement system comprising:
- a jacket of polymeric material, said jacket positioned to surround both said lead wire and said sensing component for an aggregate length of said assembly formed of said sensing component operatively engaged to said lead wire, whereby said sensing component is held in operative electrical engagement to said lead wire by a contact between said jacket and respective exterior surfaces of said sensing component and said lead wire;
- said surgical sensor assembly being employed in combination with a catheter having at least one lumen therein for translation and operation of a control wire for a surgical instrument;
- a recess formed in an exterior surface of said catheter parallel to said lumen;
- said surgical sensor assembly positioned within said recess;
- and
- a second said jacket of polymeric material formed of said heat-shrink tubing, said second jacket surrounding said exterior surface of said catheter and providing means to maintain said surgical sensor assembly positioned therein.
An engagement system of a surgical sensor assembly, formed of a sensing component in a fixed position upon, and communicating with, a lead wire, said engagement system comprising:
- a jacket of polymeric material, said jacket positioned to surround both said lead wire and said sensing component for an aggregate length of said assembly formed of said sensing component operatively engaged to said lead wire, whereby said sensing component is held in operative electrical engagement to said lead wire by a contact between said jacket and respective exterior surfaces of said sensing component and said lead wire;
- said surgical sensor assembly being employed in combination with a catheter having an interior surface wall defining at least one lumen therein for translation and operation of a control wire for a surgical instrument;
- a recess formed in said surface wall;
- and
- said surgical sensor assembly positioned within said recess;
- an insulating layer positioned between said surgical sensor assembly and said control wire.
