Abstract
A system for coupling a medical electrical lead to a medical device includes an upsizing sleeve having a plurality of spring contacts, a plurality of seal members, and contact members joined in an alternating manner with relatively rigid insulation members. At least one contact member includes an inner surface for housing a contact from the plurality of spring contacts and at least one insulation member includes an inner surface for housing a seal from the plurality of seal members.

A system for coupling a medical electrical lead to a medical device comprising:
- an upsizing sleeve, including an external surface, a plurality of contact members, a plurality of spring contacts, a plurality of relatively rigid insulation members, and a plurality of seal members;
- the plurality of contact members including outer surfaces forming a first portion of the external surface of the upsizing sleeve, and inner surfaces housing corresponding spring contacts;
- and
- the plurality of relatively rigid insulation members including outer surfaces forming a second portion of the external surface of the upsizing sleeve, and inner surfaces housing corresponding seal members;
- wherein
- each of the plurality of contact members are joined in an alternating manner with each of the plurality of rigid insulation members.
A system for coupling a medical electrical lead to a medical device comprising:
- a proximal end of the medical electrical lead including a plurality of connector rings, a plurality of insulative spacers, and a connector pin having a predetermined diameter and terminating the proximal end of the lead;
- an upsizing sleeve, including an external surface, an internal surface forming a lumen to engage the proximal end of the lead, a proximal opening, a distal end forming a distal opening including a means for strain relief, a plurality of contact members, a plurality of spring contacts, a plurality of relatively rigid insulation members, and a plurality of seal members;
- the plurality of contact members including outer surfaces forming a first portion of the external surface of the upsizing sleeve, and inner surfaces each comprising inner surfaces housing corresponding spring contacts;
- and
- the plurality of relatively rigid insulation members including outer surfaces forming a second portion of the external surface of the upsizing sleeve, and inner surfaces housing corresponding seal members;
- wherein
- each of the plurality of contact members are joined in an alternating manner with each of the plurality of rigid insulation ring members;
- the external surface of the upsizing sleeve conforms to predetermined dimensions when the proximal end of the lead is engaged within the lumen of the upsizing sleeve;
- and
- the connector pin extends proximally from the proximal opening, for a predetermined length, when the proximal end of the lead is engaged within the lumen of the upsizing sleeve.
An upsizing sleeve comprising:
- a plurality of contact members, the plurality of contact members including outer surfaces, to form a first portion of an external surface of the upsizing sleeve, and at least one from the plurality of contact members including an inner surface housing a spring contact;
- a plurality of relatively rigid insulation members, the plurality of insulation members comprising outer surfaces, to form a second portion of the external surface of the upsizing sleeve, and at least one from the plurality of insulation members including an inner surface housing a seal member;
- wherein
- the plurality of contact members is joined with the plurality of insulation members in an alternating fashion by means of mating interfaces.
