11、 Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a
12、technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matter
13、s of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This docu
14、ment was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such pa
15、tent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received. www.iso.org/patents Any trade name used in this document is information given for the convenience of users and does not cons
16、titute an endorsement. The committee responsible for this document is ISO/TC 150, Implants for surgery, sous-comit SC 2, Cardiovascular implants and extracorporeal systems. The following definitions apply in understanding how to implement an ISO International Standard and other normative ISO deliver
17、ables (TS, PAS, IWA): “shall” indicates a requirement; “should” indicates a recommendation; “may” is used to indicate that something is permitted; “can” is used to indicate that something is possible, for example, that an organization or individual is able to do something. 3.3.1 of the ISO/IEC Direc
18、tives, Part 2 (sixth edition, 2011) defines a requirement as an “expression in the content of a document conveying criteria to be fulfilled if compliance with the document is to be claimed and from which no deviation is permitted.” 3.3.2 of the ISO/IEC Directives, Part 2 (sixth edition, 2011) define
19、s a recommendation as an “expression in the content of a document conveying that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others, or that a certain course of action is preferred but not necessarily required, or that (in the negative for
20、m) a certain possibility or course of action is deprecated but not prohibited.”iv ISO 2014 All rights reserved PD ISO/TS 17137:2014 ISO/TS 17137:2014(E) Introduction Absorbable cardiovascular implants are medical devices with various clinical indications for use in the human cardiovascular blood sys
21、tem. An absorbable cardiovascular implant, or at least a portion thereof, is designed to intentionally degrade over time into products that are absorbed by the body through metabolism, assimilation, and/or excretion (elimination). Such implants can be either surgically or interventionally introduced
22、 to the site of treatment. This Technical Specification outlines requirements for intended performance, design attributes, materials, design evaluation, manufacturing, sterilization, packaging, and information supplied by the manufacturer. This Technical Specification should be considered as a suppl
23、ement to ISO 14630, which specifies general requirements for the performance of non-active surgical implants. This Technical Specification should also be considered as a supplement to relevant device-specific standards such as the ISO 25539 series specifying requirements for endovascular devices, wh
24、ich do not address degradation and other time dependent aspects of absorbable implants and coatings. This Technical Specification is not comprehensive with respect to the pharmacological evaluation of cardiovascular absorbable implants. More detailed safety and performance requirements for pha r mac
25、olog ic a l agent s included in t he absorbable c a rdiova sc u la r impla nt a re desc r ibed in ISO/ T S 12417. Only issues related to absorption combined with the cardiovascular implant are covered by this Technical Specification. NOTE For issues related to the common mechanical function of the c
26、ardiovascular implant, the reader might find it useful to consider a number of other International Standards (see Bibliography). ISO 2014 All rights reserved v PD ISO/TS 17137:2014 Cardiovascular implants and extracorporeal systems Cardiovascular absorbable implants 1 Scope This Technical Specificat
27、ion outlines design verification and validation considerations for absorbable cardiovascular implants. NOTE Due to the variations in the design of implants covered by this Technical Specification and in some cases due to the relatively recent development of some of these implants (e.g. absorbable st
28、ents), acceptable standardized in vitro tests and clinical results are not always available. As further scientific and clinical data become available, appropriate revision of this Technical Specification will be necessary. For the purpose of this Technical Specification the terms “vessel and/or vasc
29、ular space” refer to the entire circulatory system, including the heart and all vasculature. This Technical Specification is applicable to implants in direct contact with the cardiovascular system, where the intended action is upon the circulatory system. This technical specification does not addres
30、s the specific evaluation of issues associated with viable tissues, viable cells, and/or implants with non- viable biological materials and their derivatives. Additionally, procedures and devices used prior to and following the introduction of the absorbable cardiovascular implant (e.g. balloon angi
31、oplasty devices) are excluded from the scope of this Technical Specification if they do not affect the absorption aspects of the implant. A cardiovascular absorbable implant may incorporate substance(s) which, if used separately, can be considered to be a medicinal product (drug product) but the act
32、ion of the medicinal substance is ancillary to that of the implant and supports the primary mode of action of the implant. NOTE Some aspects of absorbable components of cardiovascular device-drug combination products (e.g. coatings) in their connection with drug-related aspects of the device are add
33、ressed in ISO/TS 12417. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

41、nd/or tissue over time 3.2 degradation product (noun) byproduct (noun) any intermediate or final result from the physical, metabolic, and/or chemical decomposition of a material or substance 3.3 degrade (verb) to physically, metabolically, and/or chemically decompose a material or substance 3.4 leac
42、hable (adjective) substances that can be released from a medical device or material during clinical use Note 1 to entry: In absorbable devices, leachables may be substances released from the as-manufactured product or substances generated and released as a consequence of its degradation (i.e. degrad
43、ation products). 4 Implant considerations 4.1 Classification A cardiovascular absorbable implant is a product that is considered to be a medical device that accomplishes its intended clinical use and performance over a defined time period. A cardiovascular absorbable implant accomplishes its intende
44、d clinical use and is then absorbed by the body over a finite period of time. The implants temporary nature is provided by its ability to degrade and the resulting products ability to be metabolized, assimilated, and/or excreted (eliminated) over time. An absorbable cardiovascular implant may also i
45、ncorporate a medicinal substance. However, for the purposes of this Technical Specification, if the action of the medicinal substance is ancillary to a devices primary mode of action, the product is considered to be a surgical implant. The manufacturer shall determine the acceptability of the produc
46、t for clinical use at all stages of the product life cycle.2 ISO 2014 All rights reserved PD ISO/TS 17137:2014 ISO/TS 17137:2014(E) 4.2 Intended clinical performance The intended performance of an absorbable implant shall be described and documented by addressing at least the following, with particu
47、lar regard to patients safety: a) intended purpose(s); b) intended lifetime. 4.3 Intended clinical use The intended clinical location shall be identified as one or more of the following: a) abdominal aorta; b) arterio-venous shunt for vascular access; c) carotid artery; d) coronary artery; e) corona
48、ry heart chambers; f) femoral artery; g) iliac artery; h) popliteal artery; i) intra-cerebral artery; j) renal artery; k) thoracic aorta; l) thoraco-abdominal aorta; m) tibial artery; n) other arterial or venous vessels to be specified. 4.4 Materials The requirements of ISO 14630:2012, Clause 6, sha
49、ll apply. Additional testing appropriate to specific material types (e.g. metals, polymers, drugs) shall be performed to determine material acceptability for use in the design. For example, a general guide for assessing absorbable polymeric implants can be found in ASTM F2902. In a more specific example, absorbable materials dependent on shape memory properties should be subjected to testing that assesses transformation properties. For drug-eluting absorbable implants, drug identity testing shall be perf
