Exhibit B

Development Plan

Overview

Luna will develop for Hansen a localization and shape sensing solution for Hansens robotic system designed to meet the target performance metrics
described in Exhibit A (Development Milestones) on the [***] basis set forth in (and otherwise in accordance with) Section 2.1 of the Development and Supply Agreement.

Fiber based localization will be embedded by Hansen inside a Hansen robotic catheter (both open lumen product line and closed lumen product line) to aid instinctive driving and navigation of the robotic
catheters.

The robotic catheters with embedded fiber localization capability will be configured to provide localization and shape data to the
Sensei system and related mapping module/software such that the mapping capability is supported.

[***]

The following describes the budget and summary of activities for each phase of the Development Program corresponding to each Development Milestone, with
the Total Budget Estimates listed below constituting the Budget Caps for each Development Milestone for purposes of Section 4.1 of the Agreement. For the avoidance of doubt, the description of development activities for each Development
Milestone below, and the corresponding budget therefor, shall include all the specific activities expressly described in Exhibit A for each corresponding Development Milestone (to the extent not already described below).

Notwithstanding anything else herein or in Exhibit A to the contrary, to the extent any item is designated below [***], such item shall be deemed to be
deleted from the [***] set forth in Exhibit A and this Exhibit B, and [***]
