Assemblies and methods provide for implantation of multiple medical leads to a defined space within the body, such as the epidural space, through a single entry. A catheter having multiple lumens or alternatively a single oblong lumen may be used. A distal end of the catheter enters the defined space through the single entry such that the distal ends of the multiple lumens or the oblong lumen are present in the defined space. Medical leads are introduced through the multiple lumens or the oblong lumen into the defined space. In some cases, the distal end of the catheter may be deflectable to direct the medical leads within the defined space. In other cases, sheaths may be present within each lumen of the catheter where the sheaths may be extended into the defined space and deflect to direct the medical leads that are being passed through a lumen of the sheaths.

Medical assemblies and methods for implantation of multiple medical leads through a single entry

A neuromodulation therapy is delivered via at least one electrode implanted subcutaneously and superficially to a fascia layer superficial to a nerve of a patient. In one example, an implantable medical device is deployed along a superficial surface of a deep fascia tissue layer superficial to a nerve of a patient. Electrical stimulation energy is delivered to the nerve through the deep fascia tissue layer via implantable medical device electrodes.

Minimally invasive implantable neurostimulation system

A system including a stimulation generator configured to delivery external stimulation to control or alleviate urinary or fecal incontinence. The system may also include sense electrodes configured to sense the presence of wetness. The system may provide closed loop therapy based on the presence of wetness.

External stimulation therapy for dorsal genital nerve stimulation

A medical device system for delivering a neuromodulation therapy includes a delivery tool for deploying an implantable medical device at a neuromodulation therapy site. The implantable medical device includes a housing, an electronic circuit within the housing, and an electrical lead comprising a lead body extending between a proximal end coupled to the housing and a distal end extending away from the housing and at least one electrode carried by the lead body. The delivery tool includes a first cavity for receiving the housing and a second cavity for receiving the lead. The first cavity and the second cavity are in direct communication for receiving and deploying the housing and the lead coupled to the housing concomitantly as a single unit.

An implantable medical device (IMD) has a housing enclosing an electronic circuit. The housing includes a first housing portion, a second housing portion and a joint coupling the first housing portion to the second housing portion. A polymer seal is positioned in the joint in various embodiments. Other embodiments of an IMD housing are disclosed.

The disclosure is directed to an implant tool and cannula used to facilitate the implantation of a medical device into a patient. The implant tool includes a housing that is held by a user and a needle attached to the housing. The cannula may be positioned over the needle and delivered to a target tissue within the patient. The cannula includes an electrode at a distal portion to deliver test stimulation to confirm the location of the target site or placement of the implant tool relative to the target site before removing the needle of the implant tool. In this manner, the cannula may be repositioned within the patient until the position of the implant tool and cannula relative to the target site is verified with the test stimulation.

Cannula configured to deliver test stimulation

A temporary medical electrical lead includes a connector pin and a single conductor coil. The coil being close-wound and having no turns of the coil distal portion being mechanically coupled together. The coil distal portion translates a force of no greater than 0.1 lb(0.4 N) when strained 400%.

Implantable medical electrical lead construction and associated implant systems

Medical leads include distal tip anchors that are retained by fixation mechanisms of implantation tools. The fixation mechanism may include a fixed body that has features retaining the distal tip anchor. The fixation mechanism may include a movable body that can apply tension to the distal tip anchor to force the distal tip anchor to be released from the features of the fixed body. The movable body may include an axial portion that is received by an axial hole of the fixed body to allow for axial movement of the movable body to release the distal tip anchor. The fixation mechanism may instead include an elongated flexible body that passes through the distal tip anchor and is attached to the fixed body. Tension applied to the elongated body creates a releasing motion of the distal tip anchor to free the distal tip anchor from the features of the fixed body.

Methods, tools, and assemblies for implantation of medical leads having distal tip anchors

In some examples, an implantable medical device includes an implantable housing, a neurostimulator within the housing, a plurality of electrodes, an implantable lead coupled to the housing, and an actuator formed with the housing. The implantable lead includes at least one electrode of the plurality of electrodes and one or more conductors coupling the at least one electrode to the neurostimulator. The actuator is configured to cause at least a portion of the implantable lead to deflect.

Implantable electrical stimulator with deflecting tip lead

Medical leads have one or more openly coiled filars and a distal body coupled to the openly coiled filars. The openly coiled filars provide a lead with compliance and elasticity while the distal body provides the firmness needed for placement and support of the electrodes. The openly coiled filars may transition to a linear distal portion that extends to the distal body, and the distal body may have proximal tines that fold proximally to become adjacent to the linear distal portion of the filars. The openly coiled filars may instead extend to the distal body and the proximal tines may be laterally arced to then fold against the lateral surface of the coiled filars. The tines may fold distally during explantation to allow the distal body to release and exit the body.
