MEDICAL LEADS HAVING A DISTAL BODY AND AN OPENLY COILED FILAR

Номер: US20190022374A1
Автор: Bonde Eric H., Falkner Phillip C., Hegland Michael T., Stolz Brian T., Wells Patrick D.
Принадлежит:

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. 1. A medical lead , comprising:a filar with an openly coiled central portion;a distal body having an electrode, with a distal portion of the filar passing through the distal body and being coupled to the electrode; andat least one tine extending from a most proximal point of the distal body, the at least one tine extending proximally over a portion of the openly coiled filar that is not within the distal body, the at least one tine having an arced shape over a lateral dimension such that the arced shape rests upon an arced surface of the portion of the openly coiled filar when the at least one tine is in a collapsed state while extending proximally.2. The medical lead of claim 1 , further comprising a proximal body separated from the distal body and having a contact claim 1 , with a proximal end of the coiled filar passing through the proximal body and being coupled to the contact.3. The medical lead of claim 1 , wherein the distal body is molded onto the distal portion of the linear distal end of the coiled filar.4.

Patient-intermediated therapy management

Номер: US20200030618A1

Принадлежит: MEDTRONIC INC

In some examples, controlling delivery of therapy includes using an implantable medical device comprising at least one electrode. Processing circuitry of a system comprising the device may receive, from an application running on a patient personal device, a patient request entered by the patient into the application. The processing circuitry may further determine, based on the patient request, a requested value of a therapy parameter, compare the requested value to information stored in a memory of the medical device system, the information indicating one or more allowable values of the therapy parameter, determine that the requested value is one of the allowable values based on the comparison of the requested value of the therapy parameter to the one or more allowable values, and control the implantable medical device to deliver cardiac pacing via the at least one electrode according to the requested value for a period of time.

Автор: Michael D. Baudino, Patrick D. Wells
Принадлежит: Medtronic, Inc.

An anchor for securing a therapy delivery element in a desired location within a living body is disclosed. The anchor includes an anchor body having a space, which may be a main channel, to receive the therapy delivery element. A fill port is provided in the anchor body to introduce an adhesive into the space when the therapy delivery element is positioned within the space. In one embodiment, the fill port is coupled to a fill port extension that transfers the adhesive from a dispenser located a distance from the fill port into the space. Multiple fill ports, any of which may be coupled to a respective fill port extension, may be provided to introduce the adhesive at various locations of the space. One or more of the fill ports may extend into multiple side channels to introduce the adhesive at various locations of the space.
