Embodiment Construction

[0044] For terms defined below, these definitions shall apply unless a different definition is given in the claims or elsewhere in this specification.

[0045] All numerical values ​​herein are assumed to be modified by the term "about," whether or not explicitly stated. The term "about" generally refers to a range of numbers that one of skill in the art would consider equivalent to the recited value (ie, having the same function or result). In many cases, the term "about" may include a number rounded to the nearest significant figure.

[0046]The recitation of numerical ranges by endpoints includes all numbers within that range (eg, 1-5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, and 5).

[0047] As used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the content clearly dictates otherwise. As used in this specification and the appended claims, the term "or" is generally employed in its sense including "and / or...

Abstract

Retrieval devices are used to retrieve chronically implanted devices such as leadless cardiac pacemakers (LCPs). In some cases, the retrieval device can be configured to cut or tear through at least some of the tissue that surrounds and / or encases the chronically implanted device such that the retrieval feature on the chronically implanted device can be grasped. Take to remove chronically implanted devices.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of US Provisional Patent Application No. 62 / 316,074, filed March 31, 2016, the disclosure of which is incorporated herein by reference. technical field [0003] The present disclosure relates generally to retrieval devices, and more particularly to retrieval devices for retrieval of chronically implanted medical devices. Background technique [0004] Pacemakers such as leadless cardiac pacemakers are used to sense and pace the heart, which is prone to a wide variety of incorrect heart rhythms, including but not limited to bradycardia (which is a slow heart rate) and tachycardia ( It is a high heart rate). In some cases, there may be a desire to remove a previously implanted leadless cardiac pacemaker. Because these devices are designed to be long-lived, significant tissue growth (eg, endothelialization) surrounding and even coating leadless cardiac pacemakers can occur in many cases...
