摘要:
An implantable medical device having a flexible diaphragm is provided with a housing including a shell and an outer layer. The flexible diaphragm extends along the shell. The outer layer has an outer surface and an inner surface. An adhesive coating is applied between the diaphragm and the inner surface of the outer layer. The outer layer includes a recess along the diaphragm for receiving the adhesive.

An implantable sensor module includes a housing having an inner shell and an outer layer formed to extend over and enclose the inner shell to form an outer wall of the housing, the inner shell having a thickness extending between an inner wall of the inner shell and an outer wall of the inner shell, the outer layer having an inner side engaged against the outer wall of the inner shell and having a thickness extending between the inner side and the outer wall of the housing, wherein the inner shell and the outer layer form a substantially flat portion. A flexible diaphragm is formed within the inner shell and extends between a first edge and a second edge, and a shoulder extends adjacent to the first edge to extend the outer layer laterally away from a central medial line extending between the first and second edges of the diaphragm.

Various techniques are disclosed for facilitating selection of at least one vector from among a plurality of vectors for pacing a chamber of a heart. In one example, a method includes presenting, by a computing device, a plurality of criteria by which each of the plurality of vectors may be prioritized, selecting at least one criterion from among a plurality of criteria by which each of the plurality of vectors may be prioritized, measuring the at least one selected criterion for each of the plurality of vectors, and automatically prioritizing, by the computing device, the plurality of vectors based on the measurement of the at least one selected criterion.
摘要:
An implantable lead for placement by means of a guide wire passing therethrough. The lead has an elongated insulative lead body with an axially extending lumen through at least a distal portion of the lead body. A conductor is mounted within and extends to an electrode assembly mounted to a distal portion of the lead body. A seal housing with a seal located therein located at a distal end of the lead body. The seal is located generally perpendicular to the axis of the lead body and is concave on both its proximal and distal sides. The housing is provided with a cavity adjacent each of the seal's proximal and distal sides, into which the seal may be deflected. The electrode assembly may be mounted to the seal housing.

An implantable lead including a lead body including an outer surface, a proximal end, a distal end, and at least one electrode; an electrically insulating member that extends axially over a first portion of the outer surface of the lead body between the proximal end and distal end, the electrically insulating member defining at least one aperture that exposes a first portion of the at least one electrode when in a first position over the lead body; and a reinforcement member formed at least partially of a different material than the insulating member and coupled to the insulating member, the reinforcement member extending axially over the outer surface of the lead body between the insulating member and proximal end. The reinforcement member may be configured to transfer at least one of a radial or axial force from a proximal portion of the reinforcement member to the insulating member, wherein the at least one of radial or axial force transferred to the insulating member is sufficient to move the insulating member over the outer surface of the lead body. In some examples, the lead may further include a deployable lobe member configured to anchor the reinforcement member and insulating member adjacent a tissue site within a patient.

In one example, this disclosure is directed to a method for intravascular implantation of an implantable medical device comprising positioning a distal end of an elongated outer sheath forming an inner lumen adjacent a target site within a vasculature of a patient, and partially deploying an implantable medical device from the distal opening, wherein the implantable medical device includes an expandable fixation element. A portion of the expandable fixation element assumes an expanded position when the implantable medical device is partially deployed from the distal opening. The method including advancing the distal end of the outer sheath within the vasculature with the implantable medical device partially deployed from the distal opening, and monitoring at least one of the vasculature and the portion of the expandable fixation element for deflection to determine when the size of the portion of the expandable fixation element corresponds to the size of the vasculature.

In one example, this disclosure is directed to a kit for intravascular implantation of an implantable medical device, the kit comprising an outer sheath, the outer sheath sized to traverse a vasculature of the patient, and an elongated inner sheath with a tapered distal end. The inner sheath is slidable within the inner lumen of the outer sheath and is selectably removable from the inner lumen of the outer sheath by sliding the inner sheath out of the proximal opening of the outer sheath. The kit includes an elongated deployment receptacle including a deployment bay slidable within the inner lumen of the outer sheath when the inner sheath is not within the inner lumen of the outer sheath. The deployment bay carries an implantable medical device through the inner lumen of the outer sheath and facilitates deployment of the implantable medical device from the distal end of the outer sheath.
