Atraumatic insertion of a subcutaneous device
First Claim
1. An insertion needle (10, 40, 60) for inserting a subcutaneous device (30, 50), comprising:
- a needle body (11), a distal end portion (13), the distal end portion having a pointed distal tip (14, 44) and a distally facing generally smooth surface (15, 45), wherein the needle body comprising along a portion thereof a longitudinal recess (20, 41) adapted to at least partially accommodate a subcutaneous device.

Abstract
The invention relates to a concept for placing a subcutaneous device such as a sensor at a selected site within the body of a patient, e.g. to obtain blood glucose readings. In a first aspect, an insertion needle comprises an oblong needle body and a distal end portion, the distal end portion having a pointed distal tip allowing the needle to be introduced subcutaneously and a distally facing generally smooth surface, the body comprising along a portion thereof a longitudinal groove adapted to at least partially accommodate the subcutaneous device. In a second aspect, a combination of an insertion needle and a subcutaneous device form an oblong body portion and a distal end portion formed by either of the members or in combination by the two members, the distal end portion having a pointed distal tip and a distally facing generally smooth surface. By the above configuration, a concept is provided reducing the severity of the body response following transcutaneous placement of a device as well as reducing the pain associated with the insertion.

17. A transcutaneous sensor insertion set (300), comprising:
-
a mounting base (320) adapted for mounting onto a patient'"'"'s skin, a flexible sensor device (310) having a proximal portion (312) carried by the base and a distal portion (311) protruding from the mounting base, the distal portion comprising at least one sensor element (315), an insertion needle (330) extending from the mounting base and supporting the sensor distal portion for transcutaneously placing the sensor distal portion when the mounting base is placed against a patient'"'"'s skin, wherein the insertion needle and the sensor distal portion in combination form an insertion body, the insertion body comprising a distal end portion (332) having a pointed distal tip (333) and a distally facing generally smooth surface, the distally facing surface being formed either by the insertion needle, the sensor device or in combination by the insertion needle and the sensor device, the insertion needle being arranged for sliding withdrawal from the sensor device and the mounting base. - View Dependent Claims (18)
