This international search report has been prepared by this International Searching Authority and is transmitted to the applicant according to Article 18. A copy is being transmitted to the International Bureau.
It is also accompanied by a copy of each prior art document cited in this report.
1. Basis of the report
a. With regard to the language, the international search was carried out on the basis of:
the international application in the language in which it was filed.
a translation of the international application into                                          which is the language of a translation furnished for the purposes of international search (Rules 12.3(a) and 23.1(b)).
This international search report has been established taking into account the rectification of an obvious mistake authorized by or notified to this Authority under Rule 91 (Rule 43.6bis(a)).
With regard to any nucleotide and/or amino acid sequence disclosed in the international application, the international search was carried out on the basis of a sequence listing:
2. Certain claims were found unsearchable
This international search report has not been established in respect of certain claims under Article 17(2)(a) for the following reasons:
Claims Nos.: 1-8
because they relate to subject matter not required to be searched by this Authority, namely:
The subject-matter of claims 1-8 has not been searched since it relates to a method for treatment of the human or animal body by therapy (Rule 39.1(iv) PCT). The claims comprise the step of delivering defibrillation shocks and therapeutic/pacing pulses the the living human body, therefore clearly relating to therapy. Accordingly, claims 1-8 relate to subject-matter considered by this Authority to be covered by the provisions of Rule 67.1(iv) PCT. Consequently, no opinion will be formulated with respect to the subject-matter of these claims (Article 34(4)(a)(i) PCT).
Claims Nos.:
because they relate to parts of the international application that do not comply with the prescribed requirements to such an extent that no meaningful international search can be carried out, specifically:
Claims Nos.:
because they are dependent claims and are not drafted in accordance with the second and third sentences of Rule 6.4(a).
3. Unity of invention is lacking
This International Searching Authority found multiple inventions in this international application, as follows:
1. claims: 1-15
Method and implantable medical device for delivering a multi-phase ventricular defibrillation therapy comprising 1st phase with medium-voltage shocks and 2nd phase with low-voltage pulse train, and an optional 3rd phase with pacing pulses.
2. claims: 16-36
Method, implantable medical device (IMD) and output control system for said IMD characterised by duty cycle variation to define the shape of the defibrillating shock waveform.
3. claims: 37-49
Implantable medical device and method for switching a reconfigurable defibrillator capacitor bank between parallel and series configuration during shock delivery.
As all required additional search fees were timely paid by the applicant, this international search report covers all searchable claims.
As all searchable claims could be searched without effort justifying additional fees, this Authority did not invite payment of additional fees.
As only some of the required additional search fees were timely paid by the applicant, this international search report covers only those claims for which fees were paid, specifically claims Nos.:
No required additional search fees were timely paid by the applicant. Consequently, this international search report is restricted to the invention first mentioned in the claims; it is covered by claims Nos.: 1-15
Remark on Protest
The additional search fees were accompanied by the applicant’s protest and, where applicable, the payment of a protest fee.
The additional search fees were accompanied by the applicant’s protest but the applicable protest fee was not paid within the time limit specified in the invitation.
No protest accompanied the payment of additional search fees.

The text has been established by this Authority to read as follows:
5. Abstract
