Instrument for implanting a sensor
First Claim
1. An instrument for implanting a sensor in a body part of a subject, comprising:
- a guide sheath having a first end and a second end, a bore extending along the length of guide sheath between the first end and the second end, a guide handle located at the second end and extending about the circumference of the guide sheath, and a slot extending along the length between the first end and the second open end and through the guide handle;
a delivery sheath having a first end and a second end, a bore extending along the length of the delivery sheath between the first end and the second end, a delivery handle located at the second end and extending about the circumference of the delivery sheath, a slot that extends along its length between the first end and the second end, wherein the delivery sheath is configured to be slidably disposed within the bore of the guide sheath;
a sensor having a cord extending therefrom, the sensor configured to be mounted on the first end of the delivery sheath and, when assembled with the delivery sheath, having the cord extending from the sensor within the delivery sheath bore; and
a reference pad attached to the cord, the reference pad being configured to be attached to the body of the subject, and farther being configured to be at least partially disposed within the delivery sheath handle;
wherein the slots of the guide and delivery sheaths are configured to be aligned to allow the cord to be removed through the slot in the guide sheath; and
wherein when the guide sheath, the delivery sheath, the sensor and the reference pad are assembled, the delivery sheath is partially disposed within the guide sheath, and the reference pad is matingly engaged with the delivery sheath, and the guide handle and the delivery handle have inter-engaging formations that are shaped such that the delivery sheath can only be fully received in the guide sheath when the slots of the guide sheath and the delivery sheath are aligned.

Abstract
An instrument for implanting a sensor in a body part, in which the sensor has at least one cord extending therefrom which is connected to an external device, includes a guide sheath for defining a path to the surface of the body part through overlaying soft tissue, the sheath having a bore extending along its length between first and second open ends through which the tool can pass and a slot that extends along its length between its first and second open ends. A delivery sheath for implanting the sensor in the hole has a bore extending along its length between a first open end at which the sensor can be mounted and a second end, with the cord extending from the sensor along the bore, in which the sheath has a slot that extends along its length between its first and second end, and wherein the delivery sheath can be received within the guide sheath by sliding the delivery sheath within the bore of the guide sheath. The slots of the guide and delivery sheaths can be aligned to allow the cord to be removed from the bores other than at the ends of the bores.

5. An instrument for implanting a sensor in a body part of a subject, comprising:
-
a guide sheath having a first end and a second end, a bore extending along the length of guide sheath between the first end and the second end, a guide handle located at the second end, and a guide slot extending along the length of the guide sheath between the first end and the second open end; and a delivery sheath having a first end and a second end, a bore extending along the length of the delivery sheath between the first end and the second end, a delivery handle located at the second end, a delivery slot that extends along the length of the delivery sheath between the first end and the second end, at least a portion of the delivery sheath being slidably disposable within the bore of the guide sheath; and a sensor having a cord extending therefrom, the sensor configured to be mounted on the first end of the delivery sheath and, when assembled with the delivery sheath, having the cord extending from the sensor within the delivery sheath bore; wherein the guide handle and the delivery handle have inter-engaging formations that are shaped such that the delivery sheath can only be fully received in the guide sheath when the guide slot and the delivery slots are aligned. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
