Abstract
A system and method for installing/implanting a leadless implant can include a leadless implant with shortened tine-based anchors and an implantation tool with a modified tip. The tines can extend from a surface of the leadless implant and may include a preformed curve or other shape to enable the tine to hook into or grapple tissue. The implantation tool may be provided with a modified tip to assist with proper alignment, insertion, and anchoring of the shortened tines. A tip of the implantation tool can have a reduced inner diameter to cause the tine tips to be approximately normal to the surface of the tissue to which the implant is being anchored. Upon deployment of the leadless implant, the tines of the anchoring mechanism are appropriately aligned for proper insertion so that robust anchoring is achieved.
