Instrument for implanting a sensor
First Claim
1. 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, the instrument comprising:
- 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; and
a delivery sheath for implanting the sensor in the hole, the delivery sheath having 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;
wherein 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.

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.

12. A method for implanting a sensor in a body part, in which the sensor has at least one cord extending therefrom for connection to a device external to the body part, the method comprising:
-
inserting a guide sheath which has first and second open ends and a bore extending along its length between the ends, through tissue which overlies the body part until the first open end of the sheath contacts the desired site on the body part;
mounting the sensor at a first open end of a delivery sheath, the delivery sheath having a bore extending along its length between the first open end and a second end, so that the sensor is located at the first end of the delivery sheath and the cord extends from the sensor along the delivery sheath bore; and
sliding the delivery sheath through the guide sheath until the sensor is located at the site at which the sensor is to be implanted;
implanting the sensor in the body part; and
retrieving the cord from within the bores in the sheaths, through the slots in the sheaths. - View Dependent Claims (13, 14)

- 15. A method of implanting a sensor in a body part, in which the sensor has a cord extending from it and in which the body part has a layer of overlying soft tissue, which includes the steps after implanting the sensor in the body part of manipulating the soft tissue to cause relative transverse movement between skin on the soft tissue and the body part, and then tidying excess cord which protrudes from the tissue to prevent snagging during subsequent surgical procedure steps.
