Abstract
An implantable line, in particular an electrode line and/or sensor line and/or medicine supply line for implantation in the left ventricle of the heart with perforation of the atrial or ventricular septum, includes an elongated flexible line body, an electrode and/or a sensor and/or a medicine administering device at or near the distal end of the line body, and a closure element integrally molded on the line body or connected thereto for sealing the perforation site in the septum.

An implantable line for implantation in the left ventricle of the heart with perforation of the atrial or ventricular septum, the implantable line including:
- a. an elongated flexible line body having a distal end, and including at least one of:
- (1) an electrode,
- (2) a sensor, and
- (3) a medicine administering device,
- at or near the distal end,
- b. a closure element on the line body, wherein:
- (1) the closure element seals the perforation site in the septum,
- (2) at least a portion of the closure element has an expandable section having a diameter which expands to be greater than the diameter of adjacent lengths of the line body, and
- (3) the closure element also includes a reducing section adjacent the expandable section, the reducing section having a diameter which is reduced when the diameter of the expandable section is expanded,
- c. a distal fixator:
- (1) spaced from the closure element, and
- (2) at or near the distal end of the line body,
- wherein the fixator is configured to fix the distal end of the line body in or adjacent a wall of the left ventricle away from the septum.
An implantable line for implantation in the left ventricle of the heart with perforation of the atrial or ventricular septum, the implantable line including:
- a. an elongated flexible line body having a distal end, and including at least one of:
- (1) an electrode,
- (2) a sensor, and
- (3) a medicine administering device,
- at or near the distal end,
- b. a closure element on the line body, wherein the closure element
- (1) seals the perforation site in the septum, and
- (2) includes a feed-through having opposing open ends, wherein the feed-through:
- (a) is fit about the outer diameter of the line body and through the perforation site in the septum, and
- (b) includes a section with an inner diameter that reduces upon placement of the feed-through within the septum.
An implantable line for implantation in the left ventricle of the heart with perforation of the atrial or ventricular septum, the implantable line including an elongated flexible line body having:
- a. a distal end;
- b. a closure element on or about the outer diameter of the line body, wherein:
- (1) at least a portion of the closure element has an outer diameter that expands upon placement of the closure element within the septum, and
- (2) at least a portion of the closure element has an inner diameter that is reduced when the outer diameter is expanded;
- c. an electrode situated between the distal end and the closure element.
An implantable line for implantation in the left ventricle of the heart with perforation of the atrial or ventricular septum, the implantable line including an elongated flexible line body having:
- a. a distal end;
- b. a closure element on or about the outer diameter of the line body, wherein the closure element includes:
- (1) an expandable fixator situated on or about the line body, the fixator:
- i. expanding to extend beyond the outer diameter of the line body,
- ii. including one or more members spring-biased to extend away from the outer diameter of the line body, the members being restrained toward the outer diameter of the line body by tubing retractably fit over the members, and
- iii. including a stent extending about the line body;
- (2) a reducing section having an inner diameter which reduces to closely fit about the outer diameter of the line body;
- c. an electrode situated between the distal end and the closure element.
An implantable line for implantation in the left ventricle of the heart with perforation of the atrial or ventricular septum, the implantable line including an elongated flexible line body having:
- a. a distal end;
- b. a closure element on or about the outer diameter of the line body, the closure element including two seals extending about the line body wherein:
- (1) one of the seals is defined by an expandable member situated about the line body, the expandable member expanding to extend beyond the outer diameter of the line body;
- (2) the other of the seals is defined by an anchor displaceable in its entirety along the length of the line body, the anchor having an anchor outer diameter greater than the outer diameter of the line body;
- whereby the seals may be situated on opposite sides of the septum to hold the closure element thereon;
- and
- c. an electrode situated between the distal end and the closure element.
An implantable line for implantation in the left ventricle of the heart with perforation of the atrial or ventricular septum, the implantable line including an elongated flexible line body having:
- a. a proximal end;
- b. an opposing distal end;
- c. a distal fixator at or near the distal end, the fixator including a member configured to engage a wall of the left ventricle away from the septum to engage the distal end thereon;
- d. a closure element spaced from the distal fixator, the closure element being situated on or about the outer diameter of the line body, wherein at least a portion of the closure element:
- (1) has an outer diameter that increases upon placement of the closure element within the septum, and
- (2) has an inner diameter that reduces upon placement of the closure element within the septum, wherein the portion having the reduced inner diameter is adjacent the portion having an increased outer diameter;
- e. a distal therapeutic device situated at or distally to the closure element, the distal therapeutic device including at least one of:
- (1) an electrode,
- (2) a sensor, and
- (3) a medicine administering device;
- f. a proximal therapeutic device situated at or proximally to the closure element, the distal therapeutic device including at least one of:
- (1) an electrode,
- (2) a sensor, and
- (3) a medicine administering device.
