Abstract
A tool to determine a pre-puncture needle shape to provide a desired approach to a target location based on measured patient anatomy is disclosed herein. Anatomical relationship between an outlet of an access vessel and a desired puncture sight on the interatrial septum is used to determine the pre-puncture needle shape. The tool may be used to provide a recommended preferred needle shape from a collection of predetermined needle shapes (e.g. commercially available needle shapes) and/or recommend a bent shape to which a physician may modify a predetermined needle shape to fit. Additionally, or alternatively, the tool may be used to provide a recommended preferred needle shape to manufacturers to create a bespoke needle shape for a given patient and/or a recommended preferred needle shape for patient cohort having similar anatomy within the cohort.
