Strategies to increase the INGEVITY lead strength during lead extraction procedures based on laboratory bench testing.

ABSTRACT:

Background

The INGEVITY lead (Boston Scientific, St Paul, MN, USA) has excellent clinical performance. However, its single filar design results in decreased lead tensile strength and a possible challenging extraction. This study's goal is to evaluate techniques for extracting the INGEVITY lead.

Methods

Two- and three-dimensional models were created to simulate lead extraction from a right atrial appendage lead implant with a left subclavian approach and lead/fibrosis attachment sites. Standard and unique lead extraction preparation strategies were evaluated. Traction forces were measured from a superior approach alone or in combination with a femoral approach.

Results

For lead extraction via the superior approach, leaving the terminal on the lead was the only factor i
