Introduction and Anchoring Tool for An Implantable Medical Device Element

Content Provider	The Lens
Abstract	In some examples, an apparatus may include a needle configured to define a path through tissue of a patient, tubing configured to slidably receive the needle via a proximal opening, an anchor configured to slidably receive at least a portion of the tubing, and an anchor deployment member comprising a body and an anchor engagement member. Such an apparatus may be used to introduce and anchor an implantable medical device within a patient.

Claim	1 - 22 . (canceled) 23 : An apparatus for introducing and anchoring an elongated implantable medical device element within a tissue of a patient, the apparatus comprising: a first elongated member defining a proximal end and a distal end, the first elongated member configured to define a path through tissue of a patient for insertion of the implantable medical device element into the path; a second elongated member defining a proximal opening, a distal opening, and a lumen extending between the proximal opening and the distal opening, the lumen configured to slidably receive at least a portion of the first elongated member and at least a portion of the implantable medical device element via the proximal opening, an anchor having an anchor lumen, the anchor being configured to secure the elongated implantable medical device in the path; and an anchor deployment member comprising: a body defining a channel, wherein the first elongated member is slidable out of a proximal end of the channel, and an anchor engagement member configured to bear against the anchor when the second elongated member is moved in a proximal direction relative to the body such that the second elongated member is withdrawn from the anchor lumen. 24 : The apparatus of claim 23 , wherein the channel extends from a proximal end of the body to a distal end of the body, wherein the first elongated member, the second elongated member, and the implantable medical device element are slidable through the channe 25 : The apparatus of claim 23 , wherein the first elongated member defines a first length, the channel defines a second length, and the first length is greater than the second length. 26 : The apparatus of claim 23 , wherein the anchor lumen is configured to slidably receive at least a portion of the second elongated member. 27 : The apparatus of claim 26 , wherein the anchor comprises at least one of a low-profile anchor, a sinusoidal configuration, or tines. 28 : The apparatus of claim 23 , wherein the first elongated member defines a lumen configured to slidably receive the elongated implantable medical device element. 29 : The apparatus of claim 23 , further comprising at least one actuator coupled to the second elongated member, wherein the at least one actuator is configured such that movement of the at least one actuator toward the proximal opening causes movement of the second elongated member toward the proximal opening. 30 : The apparatus of claim 29 , wherein the second elongated member is configured such that the movement of the second elongated member toward the proximal opening comprises movement of the second elongated member relative to the anchor. 31 : The apparatus of claim 23 , further comprising at least one distance marking on an outer surface of the body of the anchor deployment member, wherein the at least one distance marking is visually indicative of a position of the second elongated member relative to the anchor deployment member. 32 : The apparatus of claim 23 , wherein the anchor engagement member is separable from the body of the anchor deployment member, wherein the anchor engagement member is configured to substantially completely enclose the elongated implantable medical device element. 33 : A method for introducing and anchoring an elongated implantable medical device element within a tissue of a patient, the method comprising: defining a path through the tissue of the patient for insertion of the elongated implantable medical device element into the path, wherein defining the path through tissue of the patient comprises tunneling through tissue of the patient with a first elongated member of a medical device apparatus comprising: the first elongated member defining a proximal end and a distal end, the first elongated member configured to define the path through the tissue of the patient for insertion of the implantable medical device element into the path; a second elongated member defining a proximal opening, a distal opening, and a lumen extending between the proximal opening and the distal opening, the lumen configured to slidably receive at least a portion of the first elongated member and at least a portion of the implantable medical device element via the proximal opening, an anchor having an anchor lumen, the anchor being configured to secure the elongated implantable medical device in the path; and an anchor deployment member comprising: a body defining a channel, wherein the first elongated member is slidable out of a proximal end of the channel, and an anchor engagement member configured to bear against the anchor when the second elongated member is moved in a proximal direction relative to the body such that the second elongated member is withdrawn from the anchor lumen. 34 : The apparatus of claim 33 , wherein the channel extends from a proximal end of the body to a distal end of the body, wherein the first elongated member, the second elongated member, and the implantable medical device element are slidable through the channe 35 : The apparatus of claim 33 , wherein the first elongated member defines a first length, the channel defines a second length, and the first length is greater than the second length. 36 : The method of claim 33 , further comprising, prior to defining the path through tissue of the patient, inserting the first elongated member into the second elongated member, wherein defining the path through tissue of the patient comprises tunneling the first and second elongated members through tissue of the patient. 37 : The method of claim 36 , further comprising withdrawing the first elongated member from the second elongated member. 38 : The method of claim 36 , further comprising inserting the elongated implantable medical device element into the lumen of the second elongated member via the proximal opening of the second elongated member. 39 : The method of claim 38 , further comprising withdrawing the second elongated member to expose at least a portion of the elongated implantable medical device element. 40 : The method of claim 39 , further comprising deploying the anchor around the exposed portion of the elongated implantable medical device element, wherein the anchor lumen is configured to slidably receive at least a portion of the second elongated member and the elongated implantable medical device element. 41 : The method of claim 40 , wherein deploying the anchor around the exposed portion of the elongated implantable medical device element comprises moving the second elongated member in a proximal direction relative to the body of the anchor deployment member such that the second elongated member is withdrawn from the anchor lumen. 42 : The method of claim 40 , wherein deploying the anchor around the exposed portion of the elongated implantable medical device element comprises suturing the anchor to tissue of the patient. 43 : The method of claim 40 , further comprising withdrawing the second elongated member from tissue of the patient. 44 : The method of claim 33 , wherein tunneling through tissue of the patient with a first elongated member of a medical device apparatus comprises tunneling through tissue of the patient with the first elongated member of the medical device apparatus to a target tissue site within the patient. 45 : A system for introducing and anchoring an implantable medical device element within a tissue of a patient, the system comprising: an implantable medical device element, wherein the implantable medical device element is configured to deliver therapy to a target tissue site within a patient; and an apparatus comprising: a first elongated member defining a proximal end and a distal end, the first elongated member configured to define a path through tissue of a patient for insertion of the implantable medical device element into the path;
