Patent number: 10653440Abstract: A tip engageable with an elongated sheath member for extracting an implanted elongated structure, such as a cardiac lead, from an obstruction in a body vessel of a patient. The tip includes a tip body having a proximal end, a distal end, and a passageway extending therethrough. The tip body proximal end is engageable with the distal end of the sheath member distal end. The passageway of the tip is aligned with the passageway of the sheath such that the implanted structure is receivable therein. The tip body distal end includes a segment tapering toward a leading edge. A disrupter element, such as a plurality of helices, is disposed along the outer surface of the tip body distal end.

An introducer for the implantable member is received in a passageway of the dilator and extends along a length of the dilator to the tapered distal end. The introducer is arranged relative to the dilator such that upon a relative proximal movement of the dilator, the tapered distal tip of the dilator splits whereby the distal end of the introducer extends therethrough. A handle has a gripping mechanism for engagement with each tab for initiating proximal movement of the dilator relative to the introducer upon rotation of the gripping mechanism. The handle is structured for splitting the dilator proximal portion upon the relative proximal movement of the dilator.Type: GrantFiled: August 22, 2011Date of Patent: September 15, 2015Assignee: Cook Medical Technologies LLCInventors: Louis B.
